How to Write a Thematic Literature Review: A Beginner’s Guide

Literature reviews provide a comprehensive understanding of existing knowledge in a particular field, offer insights into gaps and trends, and ultimately lay the foundation for innovative research. However, when tackling complex topics spanning multiple issues, the conventional approach of a standard literature review might not suffice. Many researchers present a literature review without giving any thought to its organization or structure, but this is where a thematic literature review comes into play. In this article, we will explore the significance of thematic reviews, delve into how and when to undertake them, and offer invaluable guidance on structuring and crafting a compelling thematic literature review.

What is a thematic literature review?

A thematic literature review, also known as a thematic review, involves organizing and synthesizing the existing literature based on recurring themes or topics rather than a chronological or methodological sequence. Typically, when a student or researcher works intensively on their research there are many sub-domains or associated spheres of knowledge that one encounters. While these may not have a direct bearing on the main idea being explored, they provide a much-needed background or context to the discussion. This is where a thematic literature review is useful when dealing with complex research questions that involve multiple facets, as it allows for a more in-depth exploration of specific themes within the broader context.

When to opt for thematic literature review?

It is common practice for early career researchers and students to collate all the literature reviews they have undertaken under one single broad umbrella. However, when working on a literature review that involves multiple themes, lack of organization and structure can slow you down and create confusion. Deciding to embark on a thematic literature review is a strategic choice that should align with your research objectives. Here are some scenarios where opting for a thematic review is advantageous:

• Broad Research Questions: When your research question spans across various dimensions and cannot be adequately addressed through a traditional literature review.
• Interdisciplinary Research: In cases where your research draws from multiple disciplines, a thematic review helps in synthesizing diverse literature cohesively.
• Emerging Research Areas: When exploring emerging fields or topics with limited existing literature, a thematic review can provide valuable insights by focusing on available themes.
• Complex Issues: Thematic reviews are ideal for dissecting complex issues with multiple contributing factors or dimensions.

Advantages of a Thematic Literature Review

With better comprehension and broad insights, thematic literature reviews can help in identifying possible research gaps across themes. A thematic literature review has several advantages over a general or broad-based approach, especially for those working on multiple related themes.

• It provides a comprehensive understanding of specific themes within a broader context, allowing for a deep exploration of relevant literature.
• Thematic reviews offer a structured approach to organizing and synthesizing diverse sources, making it easier to identify trends, patterns, and gaps.
• Researchers can focus on key themes, enabling a more detailed analysis of specific aspects of the research question.
• Thematic reviews facilitate the integration of literature from various disciplines, offering a holistic view of the topic.
• Researchers can provide targeted recommendations or insights related to specific themes, aiding in the formulation of research hypotheses.

Now that we know the benefits of a thematic literature review, what is the best way to arrange reviewed literature in a thematic format?

How to write a thematic literature review

To effectively structure and write a thematic literature review, follow these key steps:

• Define Your Research Question: Clearly define the overarching research question or topic you aim to explore thematically. When writing a thematic literature review, go through different literature review sections of published research work and understand the subtle nuances associated with this approach.
• Identify Themes: Analyze the literature to identify recurring themes or topics relevant to your research question. Categorize the bibliography by dividing them into relevant clusters or units, each dealing with a specific issue. For example, you can divide a topic based on a theoretical approach, methodology, discipline or by epistemology. A theoretical review of related literature for example, may also look to break down geography or issues pertaining to a single country into its different parts or along rural and urban divides.
• Organize the Literature: Group the literature into thematic clusters based on the identified themes. Each cluster represents a different aspect of your research question. It is up to you to define the different narratives of thematic literature reviews depending on the project being undertaken; there is no one formal way of doing this. You can weigh how specific areas stack up against others in terms of existing literature or studies and how many more aspects may need to be added or further looked into.
• Review and Synthesize: Within each thematic cluster, review and synthesize the relevant literature, highlighting key findings and insights. It is recommended to identify any theme-related strengths or weaknesses using an analytical lens.
• Integrate Themes: Analyze how the themes interact with each other, draw linkages between earlier studies and see how they contribute to your own research. A thematic literature review presents readers with a comprehensive overview of the literature available on and around the research topic.
• Provide a Framework: Develop a framework or conceptual model that illustrates the relationships between the themes. Present the most relevant part of the thematic review toward the end and study it in greater detail as it reflects the literature most relevant and directly related to the main research topic.
• Conclusion: Conclude your thematic literature review by summarizing the key findings and their implications for your research question. Be sure to highlight any gaps or areas requiring further investigation in this section.
• Cite and Reference: It is important to remember that a thematic review of literature for a PhD thesis or research paper lends greater credibility to the student or researcher. So ensure that you properly cite and reference all sources according to your chosen citation style.
• Edit and Proofread: Take some time to review your work, ensure proper structure and flow and eliminate any language, grammar, or spelling errors that could deviate reader attention. This will help you deliver a well-structured and elegantly written thematic literature review.

Thematic literature review example

In essence, a thematic literature review allows researchers to dissect complex topics into smaller manageable themes, providing a more focused and structured approach to literature synthesis. This method empowers researchers to gain deeper insights, identify gaps, and generate new knowledge within the context of their research.

To illustrate the process mentioned above, let’s consider an example of a thematic literature review in the context of sustainable development. Imagine the overarching research question is: “What are the key factors influencing sustainable urban planning?” Potential themes could include environmental sustainability, social equity, economic viability, and governance. Each theme would have a dedicated section in the review, summarizing relevant literature and discussing how these factors intersect and impact sustainable urban planning. Close with a strong conclusion that highlights research gaps or areas of investigation. Finally, review and refine the thematic literature review, adding citations and references as required.

In conclusion, when tackling multifaceted research questions, a thematic literature review proves to be an indispensable tool for researchers and students alike. By adopting this approach, scholars can navigate the intricate web of existing literature, unearth meaningful patterns, and contribute to the advancement of knowledge in their respective fields. We hope the information in this article helps you create thematic reviews that illuminate your path to new discoveries and innovative insights.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example 

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:  

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

Thematic Analysis Literature Review

A thematic literature review serves as a critical tool for synthesizing research findings within a specific subject area. By categorizing existing literature into themes, this method offers a structured approach to identify and analyze patterns and trends across studies. The primary goal is to provide a clear and concise overview that aids scholars and practitioners in understanding the key discussions and developments within a field. Unlike traditional literature reviews , which may adopt a chronological approach or focus on individual studies, a thematic literature review emphasizes the aggregation of findings through key themes and thematic connections. This introduction sets the stage for a detailed examination of what constitutes a thematic literature review, its benefits, and guidance on effectively structuring and writing one.

A thematic literature review methodically organizes and examines a body of literature by identifying, analyzing, and reporting themes found within texts such as journal articles, conference proceedings, dissertations, and other forms of academic writing. While a particular journal article may offer some specific insight, a synthesis of knowledge through a literature review can provide a comprehensive overview of theories across relevant sources in a particular field.

Unlike other review types that might organize literature chronologically or by methodology , a thematic review focuses on recurring themes or patterns across a collection of works. This approach enables researchers to draw together previous research to synthesize findings from different research contexts and methodologies, highlighting the overarching trends and insights within a field.

At its core, a thematic approach to a literature review research project involves several key steps. Initially, it requires the comprehensive collection of relevant literature that aligns with the review's research question or objectives. Following this, the process entails a meticulous analysis of the texts to identify common themes that emerge across the studies. These themes are not pre-defined but are discovered through a careful reading and synthesis of the literature.

The thematic analysis process is iterative, often involving the refinement of themes as the review progresses. It allows for the integration of a broad range of literature, facilitating a multidimensional understanding of the research topic. By organizing literature thematically, the review illuminates how various studies contribute to each theme, providing insights into the depth and breadth of research in the area.

A thematic literature review thus serves as a foundational element in research, offering a nuanced and comprehensive perspective on a topic. It not only aids in identifying gaps in the existing literature but also guides future research directions by underscoring areas that warrant further investigation. Ultimately, a thematic literature review empowers researchers to construct a coherent narrative that weaves together disparate studies into a unified analysis.

Conducting a literature review thematically provides a comprehensive and nuanced synthesis of research findings, distinguishing it from other types of literature reviews. Its structured approach not only facilitates a deeper understanding of the subject area but also enhances the clarity and relevance of the review. Here are three significant advantages of employing a thematic analysis in literature reviews.

Enhanced understanding of the research field

Thematic literature reviews allow for a detailed exploration of the research landscape, presenting themes that capture the essence of the subject area. By identifying and analyzing these themes, reviewers can construct a narrative that reflects the complexity and multifaceted nature of the field.

This process aids in uncovering underlying patterns and relationships, offering a more profound and insightful examination of the literature. As a result, readers gain an enriched understanding of the key concepts, debates, and evolutionary trajectories within the research area.

Identification of research gaps and trends

One of the pivotal benefits of a thematic literature review is its ability to highlight gaps in the existing body of research. By systematically organizing the literature into themes, reviewers can pinpoint areas that are under-explored or warrant further investigation.

Additionally, this method can reveal emerging trends and shifts in research focus, guiding scholars toward promising areas for future study. The thematic structure thus serves as a roadmap, directing researchers toward uncharted territories and new research questions .

Facilitates comparative analysis and integration of findings

A thematic literature review excels in synthesizing findings from diverse studies, enabling a coherent and integrated overview. By concentrating on themes rather than individual studies, the review can draw comparisons and contrasts across different research contexts and methodologies . This comparative analysis enriches the review, offering a panoramic view of the field that acknowledges both consensus and divergence among researchers.

Moreover, the thematic framework supports the integration of findings, presenting a unified and comprehensive portrayal of the research area. Such integration is invaluable for scholars seeking to navigate the extensive body of literature and extract pertinent insights relevant to their own research questions or objectives.

The process of structuring and writing a thematic literature review is pivotal in presenting research in a clear, coherent, and impactful manner. This review type necessitates a methodical approach to not only unearth and categorize key themes but also to articulate them in a manner that is both accessible and informative to the reader. The following sections outline essential stages in the thematic analysis process for literature reviews , offering a structured pathway from initial planning to the final presentation of findings.

Identifying and categorizing themes

The initial phase in a thematic literature review is the identification of themes within the collected body of literature. This involves a detailed examination of texts to discern patterns, concepts, and ideas that recur across the research landscape. Effective identification hinges on a thorough and nuanced reading of the literature, where the reviewer actively engages with the content to extract and note significant thematic elements. Once identified, these themes must be meticulously categorized, often requiring the reviewer to discern between overarching themes and more nuanced sub-themes, ensuring a logical and hierarchical organization of the review content.

Analyzing and synthesizing themes

After categorizing the themes, the next step involves a deeper analysis and synthesis of the identified themes. This stage is critical for understanding the relationships between themes and for interpreting the broader implications of the thematic findings. Analysis may reveal how themes evolve over time, differ across methodologies or contexts, or converge to highlight predominant trends in the research area. Synthesis involves integrating insights from various studies to construct a comprehensive narrative that encapsulates the thematic essence of the literature, offering new interpretations or revealing gaps in existing research.

Presenting and discussing findings

The final stage of the thematic literature review is the discussion of the thematic findings in a research paper or presentation. This entails not only a descriptive account of identified themes but also a critical examination of their significance within the research field. Each theme should be discussed in detail, elucidating its relevance, the extent of research support, and its implications for future studies. The review should culminate in a coherent and compelling narrative that not only summarizes the key thematic findings but also situates them within the broader research context, offering valuable insights and directions for future inquiry.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

Prevent plagiarism, run a free check.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

What Is a Literature Review?

Review the literature, write the literature review, further reading, learning objectives, attribution.

This guide is designed to:

• Identify the sections and purpose of a literature review in academic writing
• Review practical strategies and organizational methods for preparing a literature review

A literature review is a summary and synthesis of scholarly research on a specific topic. It should answer questions such as:

• What research has been done on the topic?
• Who are the key researchers and experts in the field?
• What are the common theories and methodologies?
• Are there challenges, controversies, and contradictions?
• Are there gaps in the research that your approach addresses?

The process of reviewing existing research allows you to fine-tune your research question and contextualize your own work. Preparing a literature review is a cyclical process. You may find that the research question you begin with evolves as you learn more about the topic.

Once you have defined your research question , focus on learning what other scholars have written on the topic.

In order to  do a thorough search of the literature  on the topic, define the basic criteria:

• Databases and journals: Look at the  subject guide  related to your topic for recommended databases. Review the  tutorial on finding articles  for tips. 
• Books: Search BruKnow, the Library's catalog. Steps to searching ebooks are covered in the  Finding Ebooks tutorial .
• What time period should it cover? Is currency important?
• Do I know of primary and secondary sources that I can use as a way to find other information?
• What should I be aware of when looking at popular, trade, and scholarly resources ? 

One strategy is to review bibliographies for sources that relate to your interest. For more on this technique, look at the tutorial on finding articles when you have a citation .

Tip: Use a Synthesis Matrix

As you read sources, themes will emerge that will help you to organize the review. You can use a simple Synthesis Matrix to track your notes as you read. From this work, a concept map emerges that provides an overview of the literature and ways in which it connects. Working with Zotero to capture the citations, you build the structure for writing your literature review.

How do I know when I am done?

A key indicator for knowing when you are done is running into the same articles and materials. With no new information being uncovered, you are likely exhausting your current search and should modify search terms or search different catalogs or databases. It is also possible that you have reached a point when you can start writing the literature review.

Your literature review should be focused on the topic defined in your research question. It should be written in a logical, structured way and maintain an objective perspective and use a formal voice.

Review the Summary Table you created for themes and connecting ideas. Use the following guidelines to prepare an outline of the main points you want to make. 

• Synthesize previous research on the topic.
• Aim to include both summary and synthesis.
• Include literature that supports your research question as well as that which offers a different perspective.
• Avoid relying on one author or publication too heavily.
• Select an organizational structure, such as chronological, methodological, and thematic.

The three elements of a literature review are introduction, body, and conclusion.

Introduction

• Define the topic of the literature review, including any terminology.
• Introduce the central theme and organization of the literature review.
• Summarize the state of research on the topic.
• Frame the literature review with your research question.
• Focus on ways to have the body of literature tell its own story. Do not add your own interpretations at this point.
• Look for patterns and find ways to tie the pieces together.
• Summarize instead of quote.
• Weave the points together rather than list summaries of each source.
• Include the most important sources, not everything you have read.
• Summarize the review of the literature.
• Identify areas of further research on the topic.
• Connect the review with your research.

Structuring Your Literature Review: Visualizing Key Themes and Sub-themes

Introduction.

Embarking on the journey of a literature review is akin to setting sail into a vast ocean of knowledge, where clarity and coherence serve as your guiding stars. In this second part of our Literature Review Series, we will delve into structuring and organizing your review, using visual representation as a compass to navigate through the sea of information.

Visual Representation

Picture this: your literature review as a sprawling cherry blossom tree, its branches stretching out to embrace the essence of your research, with each delicate bloom representing a key theme and every petal symbolizing a sub-theme. Visual metaphors like this breathe life into the abstract, transforming words into vibrant imagery. As you paint the canvas of knowledge with your insights, let these visuals guide your journey toward clarity and understanding.

Main Themes

At the heart of your literature review lie the main themes, like sturdy branches supporting the weight of your analysis. But how do you identify them amidst the foliage of information? Look for recurring patterns, prominent concepts, and overarching ideas that define your research landscape. By distilling this wealth of information into three major themes, you lay the groundwork for a robust framework that will shape your narrative. Think of it as unearthing hidden gems from the depths of scholarly discourse, each one a testament to the richness of your field.

But the beauty of a literature review lies in its intricacies, its ability to capture the nuances and complexities that define a subject. Venture beyond the main branches and into the realm of sub-themes, where subtleties await discovery. For every major theme, uncover three sub-themes that offer depth and granularity to your analysis. These sub-branches serve as pathways to specialized areas of interest, illuminating facets of your topic that might otherwise remain in shadow. Imagine yourself as an intrepid explorer, charting new territories in the landscape of knowledge, guided by the light of inquiry.

Expanding on Sub-themes

Delving deeper into sub-themes enriches the texture of your literature review, providing readers with a nuanced understanding of the subject. Consider, for instance, a literature review exploring the impact of climate change on global agriculture. While the main theme may encompass broad concepts such as "Climate Change Effects," delving into sub-themes like "Crop Adaptation Strategies," "Water Management Practices," and "Policy Interventions" offers a more comprehensive view of the topic. Each sub-theme acts as a lens through which to examine the multifaceted dimensions of the overarching theme, shedding light on diverse perspectives and contributing to a more holistic analysis.

Furthermore, sub-themes allow you to highlight specific areas of interest or contention within your research area. By identifying key sub-themes, you can structure your literature review in a way that reflects the breadth and depth of scholarly discourse, ensuring that no important aspect goes unnoticed. For example, in a review of the literature on mental health interventions, sub-themes such as "Cognitive Behavioral Therapy," "Pharmacological Treatments," and "Community-Based Programs" offer insight into different approaches to addressing mental health issues. Each sub-theme represents a distinct avenue of inquiry, contributing unique insights to the overall discussion.

In the tapestry of academia, a well-structured literature review serves as a thread that binds together disparate ideas and perspectives. By embracing visual representation and organizing key themes and sub-themes, you not only enhance the clarity of your analysis but also invite readers to embark on a journey of discovery alongside you. So fear not, fellow scholar, for with the tools of visualization and organization at your disposal, you are well-equipped to navigate the labyrinth of knowledge and emerge victorious on the shores of understanding.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

How to Write a Literature Review

What is a literature review.

• What Is the Literature
• Writing the Review

A literature review is much more than an annotated bibliography or a list of separate reviews of articles and books. It is a critical, analytical summary and synthesis of the current knowledge of a topic. Thus it should compare and relate different theories, findings, etc, rather than just summarize them individually. In addition, it should have a particular focus or theme to organize the review. It does not have to be an exhaustive account of everything published on the topic, but it should discuss all the significant academic literature and other relevant sources important for that focus.

This is meant to be a general guide to writing a literature review: ways to structure one, what to include, how it supplements other research. For more specific help on writing a review, and especially for help on finding the literature to review, sign up for a Personal Research Session .

The specific organization of a literature review depends on the type and purpose of the review, as well as on the specific field or topic being reviewed. But in general, it is a relatively brief but thorough exploration of past and current work on a topic. Rather than a chronological listing of previous work, though, literature reviews are usually organized thematically, such as different theoretical approaches, methodologies, or specific issues or concepts involved in the topic. A thematic organization makes it much easier to examine contrasting perspectives, theoretical approaches, methodologies, findings, etc, and to analyze the strengths and weaknesses of, and point out any gaps in, previous research. And this is the heart of what a literature review is about. A literature review may offer new interpretations, theoretical approaches, or other ideas; if it is part of a research proposal or report it should demonstrate the relationship of the proposed or reported research to others' work; but whatever else it does, it must provide a critical overview of the current state of research efforts. 

Literature reviews are common and very important in the sciences and social sciences. They are less common and have a less important role in the humanities, but they do have a place, especially stand-alone reviews.

Types of Literature Reviews

There are different types of literature reviews, and different purposes for writing a review, but the most common are:

• Stand-alone literature review articles . These provide an overview and analysis of the current state of research on a topic or question. The goal is to evaluate and compare previous research on a topic to provide an analysis of what is currently known, and also to reveal controversies, weaknesses, and gaps in current work, thus pointing to directions for future research. You can find examples published in any number of academic journals, but there is a series of Annual Reviews of *Subject* which are specifically devoted to literature review articles. Writing a stand-alone review is often an effective way to get a good handle on a topic and to develop ideas for your own research program. For example, contrasting theoretical approaches or conflicting interpretations of findings can be the basis of your research project: can you find evidence supporting one interpretation against another, or can you propose an alternative interpretation that overcomes their limitations?
• Part of a research proposal . This could be a proposal for a PhD dissertation, a senior thesis, or a class project. It could also be a submission for a grant. The literature review, by pointing out the current issues and questions concerning a topic, is a crucial part of demonstrating how your proposed research will contribute to the field, and thus of convincing your thesis committee to allow you to pursue the topic of your interest or a funding agency to pay for your research efforts.
• Part of a research report . When you finish your research and write your thesis or paper to present your findings, it should include a literature review to provide the context to which your work is a contribution. Your report, in addition to detailing the methods, results, etc. of your research, should show how your work relates to others' work.

A literature review for a research report is often a revision of the review for a research proposal, which can be a revision of a stand-alone review. Each revision should be a fairly extensive revision. With the increased knowledge of and experience in the topic as you proceed, your understanding of the topic will increase. Thus, you will be in a better position to analyze and critique the literature. In addition, your focus will change as you proceed in your research. Some areas of the literature you initially reviewed will be marginal or irrelevant for your eventual research, and you will need to explore other areas more thoroughly. 

Examples of Literature Reviews

See the series of Annual Reviews of *Subject* which are specifically devoted to literature review articles to find many examples of stand-alone literature reviews in the biomedical, physical, and social sciences. 

Research report articles vary in how they are organized, but a common general structure is to have sections such as:

• Abstract - Brief summary of the contents of the article
• Introduction - A explanation of the purpose of the study, a statement of the research question(s) the study intends to address
• Literature review - A critical assessment of the work done so far on this topic, to show how the current study relates to what has already been done
• Methods - How the study was carried out (e.g. instruments or equipment, procedures, methods to gather and analyze data)
• Results - What was found in the course of the study
• Discussion - What do the results mean
• Conclusion - State the conclusions and implications of the results, and discuss how it relates to the work reviewed in the literature review; also, point to directions for further work in the area

Here are some articles that illustrate variations on this theme. There is no need to read the entire articles (unless the contents interest you); just quickly browse through to see the sections, and see how each section is introduced and what is contained in them.

The Determinants of Undergraduate Grade Point Average: The Relative Importance of Family Background, High School Resources, and Peer Group Effects , in The Journal of Human Resources , v. 34 no. 2 (Spring 1999), p. 268-293.

This article has a standard breakdown of sections:

• Introduction
• Literature Review
• Some discussion sections

First Encounters of the Bureaucratic Kind: Early Freshman Experiences with a Campus Bureaucracy , in The Journal of Higher Education , v. 67 no. 6 (Nov-Dec 1996), p. 660-691.

This one does not have a section specifically labeled as a "literature review" or "review of the literature," but the first few sections cite a long list of other sources discussing previous research in the area before the authors present their own study they are reporting.

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

Literature Review

Definition:

A literature review is a comprehensive and critical analysis of the existing literature on a particular topic or research question. It involves identifying, evaluating, and synthesizing relevant literature, including scholarly articles, books, and other sources, to provide a summary and critical assessment of what is known about the topic.

Types of Literature Review

Types of Literature Review are as follows:

• Narrative literature review : This type of review involves a comprehensive summary and critical analysis of the available literature on a particular topic or research question. It is often used as an introductory section of a research paper.
• Systematic literature review: This is a rigorous and structured review that follows a pre-defined protocol to identify, evaluate, and synthesize all relevant studies on a specific research question. It is often used in evidence-based practice and systematic reviews.
• Meta-analysis: This is a quantitative review that uses statistical methods to combine data from multiple studies to derive a summary effect size. It provides a more precise estimate of the overall effect than any individual study.
• Scoping review: This is a preliminary review that aims to map the existing literature on a broad topic area to identify research gaps and areas for further investigation.
• Critical literature review : This type of review evaluates the strengths and weaknesses of the existing literature on a particular topic or research question. It aims to provide a critical analysis of the literature and identify areas where further research is needed.
• Conceptual literature review: This review synthesizes and integrates theories and concepts from multiple sources to provide a new perspective on a particular topic. It aims to provide a theoretical framework for understanding a particular research question.
• Rapid literature review: This is a quick review that provides a snapshot of the current state of knowledge on a specific research question or topic. It is often used when time and resources are limited.
• Thematic literature review : This review identifies and analyzes common themes and patterns across a body of literature on a particular topic. It aims to provide a comprehensive overview of the literature and identify key themes and concepts.
• Realist literature review: This review is often used in social science research and aims to identify how and why certain interventions work in certain contexts. It takes into account the context and complexities of real-world situations.
• State-of-the-art literature review : This type of review provides an overview of the current state of knowledge in a particular field, highlighting the most recent and relevant research. It is often used in fields where knowledge is rapidly evolving, such as technology or medicine.
• Integrative literature review: This type of review synthesizes and integrates findings from multiple studies on a particular topic to identify patterns, themes, and gaps in the literature. It aims to provide a comprehensive understanding of the current state of knowledge on a particular topic.
• Umbrella literature review : This review is used to provide a broad overview of a large and diverse body of literature on a particular topic. It aims to identify common themes and patterns across different areas of research.
• Historical literature review: This type of review examines the historical development of research on a particular topic or research question. It aims to provide a historical context for understanding the current state of knowledge on a particular topic.
• Problem-oriented literature review : This review focuses on a specific problem or issue and examines the literature to identify potential solutions or interventions. It aims to provide practical recommendations for addressing a particular problem or issue.
• Mixed-methods literature review : This type of review combines quantitative and qualitative methods to synthesize and analyze the available literature on a particular topic. It aims to provide a more comprehensive understanding of the research question by combining different types of evidence.

Parts of Literature Review

Parts of a literature review are as follows:

Introduction

The introduction of a literature review typically provides background information on the research topic and why it is important. It outlines the objectives of the review, the research question or hypothesis, and the scope of the review.

Literature Search

This section outlines the search strategy and databases used to identify relevant literature. The search terms used, inclusion and exclusion criteria, and any limitations of the search are described.

Literature Analysis

The literature analysis is the main body of the literature review. This section summarizes and synthesizes the literature that is relevant to the research question or hypothesis. The review should be organized thematically, chronologically, or by methodology, depending on the research objectives.

Critical Evaluation

Critical evaluation involves assessing the quality and validity of the literature. This includes evaluating the reliability and validity of the studies reviewed, the methodology used, and the strength of the evidence.

The conclusion of the literature review should summarize the main findings, identify any gaps in the literature, and suggest areas for future research. It should also reiterate the importance of the research question or hypothesis and the contribution of the literature review to the overall research project.

The references list includes all the sources cited in the literature review, and follows a specific referencing style (e.g., APA, MLA, Harvard).

How to write Literature Review

Here are some steps to follow when writing a literature review:

• Define your research question or topic : Before starting your literature review, it is essential to define your research question or topic. This will help you identify relevant literature and determine the scope of your review.
• Conduct a comprehensive search: Use databases and search engines to find relevant literature. Look for peer-reviewed articles, books, and other academic sources that are relevant to your research question or topic.
• Evaluate the sources: Once you have found potential sources, evaluate them critically to determine their relevance, credibility, and quality. Look for recent publications, reputable authors, and reliable sources of data and evidence.
• Organize your sources: Group the sources by theme, method, or research question. This will help you identify similarities and differences among the literature, and provide a structure for your literature review.
• Analyze and synthesize the literature : Analyze each source in depth, identifying the key findings, methodologies, and conclusions. Then, synthesize the information from the sources, identifying patterns and themes in the literature.
• Write the literature review : Start with an introduction that provides an overview of the topic and the purpose of the literature review. Then, organize the literature according to your chosen structure, and analyze and synthesize the sources. Finally, provide a conclusion that summarizes the key findings of the literature review, identifies gaps in knowledge, and suggests areas for future research.
• Edit and proofread: Once you have written your literature review, edit and proofread it carefully to ensure that it is well-organized, clear, and concise.

Examples of Literature Review

Here’s an example of how a literature review can be conducted for a thesis on the topic of “ The Impact of Social Media on Teenagers’ Mental Health”:

• Start by identifying the key terms related to your research topic. In this case, the key terms are “social media,” “teenagers,” and “mental health.”
• Use academic databases like Google Scholar, JSTOR, or PubMed to search for relevant articles, books, and other publications. Use these keywords in your search to narrow down your results.
• Evaluate the sources you find to determine if they are relevant to your research question. You may want to consider the publication date, author’s credentials, and the journal or book publisher.
• Begin reading and taking notes on each source, paying attention to key findings, methodologies used, and any gaps in the research.
• Organize your findings into themes or categories. For example, you might categorize your sources into those that examine the impact of social media on self-esteem, those that explore the effects of cyberbullying, and those that investigate the relationship between social media use and depression.
• Synthesize your findings by summarizing the key themes and highlighting any gaps or inconsistencies in the research. Identify areas where further research is needed.
• Use your literature review to inform your research questions and hypotheses for your thesis.

For example, after conducting a literature review on the impact of social media on teenagers’ mental health, a thesis might look like this:

“Using a mixed-methods approach, this study aims to investigate the relationship between social media use and mental health outcomes in teenagers. Specifically, the study will examine the effects of cyberbullying, social comparison, and excessive social media use on self-esteem, anxiety, and depression. Through an analysis of survey data and qualitative interviews with teenagers, the study will provide insight into the complex relationship between social media use and mental health outcomes, and identify strategies for promoting positive mental health outcomes in young people.”

Applications of Literature Review

some applications of literature review in different fields:

• Social Sciences: In social sciences, literature reviews are used to identify gaps in existing research, to develop research questions, and to provide a theoretical framework for research. Literature reviews are commonly used in fields such as sociology, psychology, anthropology, and political science.
• Natural Sciences: In natural sciences, literature reviews are used to summarize and evaluate the current state of knowledge in a particular field or subfield. Literature reviews can help researchers identify areas where more research is needed and provide insights into the latest developments in a particular field. Fields such as biology, chemistry, and physics commonly use literature reviews.
• Health Sciences: In health sciences, literature reviews are used to evaluate the effectiveness of treatments, identify best practices, and determine areas where more research is needed. Literature reviews are commonly used in fields such as medicine, nursing, and public health.
• Humanities: In humanities, literature reviews are used to identify gaps in existing knowledge, develop new interpretations of texts or cultural artifacts, and provide a theoretical framework for research. Literature reviews are commonly used in fields such as history, literary studies, and philosophy.

Role of Literature Review in Research

Here are some applications of literature review in research:

• Identifying Research Gaps : Literature review helps researchers identify gaps in existing research and literature related to their research question. This allows them to develop new research questions and hypotheses to fill those gaps.
• Developing Theoretical Framework: Literature review helps researchers develop a theoretical framework for their research. By analyzing and synthesizing existing literature, researchers can identify the key concepts, theories, and models that are relevant to their research.
• Selecting Research Methods : Literature review helps researchers select appropriate research methods and techniques based on previous research. It also helps researchers to identify potential biases or limitations of certain methods and techniques.
• Data Collection and Analysis: Literature review helps researchers in data collection and analysis by providing a foundation for the development of data collection instruments and methods. It also helps researchers to identify relevant data sources and identify potential data analysis techniques.
• Communicating Results: Literature review helps researchers to communicate their results effectively by providing a context for their research. It also helps to justify the significance of their findings in relation to existing research and literature.

Purpose of Literature Review

Some of the specific purposes of a literature review are as follows:

• To provide context: A literature review helps to provide context for your research by situating it within the broader body of literature on the topic.
• To identify gaps and inconsistencies: A literature review helps to identify areas where further research is needed or where there are inconsistencies in the existing literature.
• To synthesize information: A literature review helps to synthesize the information from multiple sources and present a coherent and comprehensive picture of the current state of knowledge on the topic.
• To identify key concepts and theories : A literature review helps to identify key concepts and theories that are relevant to your research question and provide a theoretical framework for your study.
• To inform research design: A literature review can inform the design of your research study by identifying appropriate research methods, data sources, and research questions.

Characteristics of Literature Review

Some Characteristics of Literature Review are as follows:

• Identifying gaps in knowledge: A literature review helps to identify gaps in the existing knowledge and research on a specific topic or research question. By analyzing and synthesizing the literature, you can identify areas where further research is needed and where new insights can be gained.
• Establishing the significance of your research: A literature review helps to establish the significance of your own research by placing it in the context of existing research. By demonstrating the relevance of your research to the existing literature, you can establish its importance and value.
• Informing research design and methodology : A literature review helps to inform research design and methodology by identifying the most appropriate research methods, techniques, and instruments. By reviewing the literature, you can identify the strengths and limitations of different research methods and techniques, and select the most appropriate ones for your own research.
• Supporting arguments and claims: A literature review provides evidence to support arguments and claims made in academic writing. By citing and analyzing the literature, you can provide a solid foundation for your own arguments and claims.
• I dentifying potential collaborators and mentors: A literature review can help identify potential collaborators and mentors by identifying researchers and practitioners who are working on related topics or using similar methods. By building relationships with these individuals, you can gain valuable insights and support for your own research and practice.
• Keeping up-to-date with the latest research : A literature review helps to keep you up-to-date with the latest research on a specific topic or research question. By regularly reviewing the literature, you can stay informed about the latest findings and developments in your field.

Advantages of Literature Review

There are several advantages to conducting a literature review as part of a research project, including:

• Establishing the significance of the research : A literature review helps to establish the significance of the research by demonstrating the gap or problem in the existing literature that the study aims to address.
• Identifying key concepts and theories: A literature review can help to identify key concepts and theories that are relevant to the research question, and provide a theoretical framework for the study.
• Supporting the research methodology : A literature review can inform the research methodology by identifying appropriate research methods, data sources, and research questions.
• Providing a comprehensive overview of the literature : A literature review provides a comprehensive overview of the current state of knowledge on a topic, allowing the researcher to identify key themes, debates, and areas of agreement or disagreement.
• Identifying potential research questions: A literature review can help to identify potential research questions and areas for further investigation.
• Avoiding duplication of research: A literature review can help to avoid duplication of research by identifying what has already been done on a topic, and what remains to be done.
• Enhancing the credibility of the research : A literature review helps to enhance the credibility of the research by demonstrating the researcher’s knowledge of the existing literature and their ability to situate their research within a broader context.

Limitations of Literature Review

Limitations of Literature Review are as follows:

• Limited scope : Literature reviews can only cover the existing literature on a particular topic, which may be limited in scope or depth.
• Publication bias : Literature reviews may be influenced by publication bias, which occurs when researchers are more likely to publish positive results than negative ones. This can lead to an incomplete or biased picture of the literature.
• Quality of sources : The quality of the literature reviewed can vary widely, and not all sources may be reliable or valid.
• Time-limited: Literature reviews can become quickly outdated as new research is published, making it difficult to keep up with the latest developments in a field.
• Subjective interpretation : Literature reviews can be subjective, and the interpretation of the findings can vary depending on the researcher’s perspective or bias.
• Lack of original data : Literature reviews do not generate new data, but rather rely on the analysis of existing studies.
• Risk of plagiarism: It is important to ensure that literature reviews do not inadvertently contain plagiarism, which can occur when researchers use the work of others without proper attribution.

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

Pheeww, so damn helpful, thank you for this informative piece.

I’m doing a research project topic ; stool analysis for parasitic worm (enteric) worm, how do I structure it, thanks.

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it

Asking questions are actually fastidious thing if you are not understanding anything fully, but this article presents good understanding yet.

Theme Definition

What is theme? Here’s a quick and simple definition:

A theme is a universal idea, lesson, or message explored throughout a work of literature. One key characteristic of literary themes is their universality, which is to say that themes are ideas that not only apply to the specific characters and events of a book or play, but also express broader truths about human experience that readers can apply to their own lives. For instance, John Steinbeck's The Grapes of Wrath (about a family of tenant farmers who are displaced from their land in Oklahoma) is a book whose themes might be said to include the inhumanity of capitalism, as well as the vitality and necessity of family and friendship.

Some additional key details about theme:

• All works of literature have themes. The same work can have multiple themes, and many different works explore the same or similar themes.
• Themes are sometimes divided into thematic concepts and thematic statements . A work's thematic concept is the broader topic it touches upon (love, forgiveness, pain, etc.) while its thematic statement is what the work says about that topic. For example, the thematic concept of a romance novel might be love, and, depending on what happens in the story, its thematic statement might be that "Love is blind," or that "You can't buy love . "
• Themes are almost never stated explicitly. Oftentimes you can identify a work's themes by looking for a repeating symbol , motif , or phrase that appears again and again throughout a story, since it often signals a recurring concept or idea.

Theme Pronunciation

Here's how to pronounce theme: theem

Identifying Themes

Every work of literature—whether it's an essay, a novel, a poem, or something else—has at least one theme. Therefore, when analyzing a given work, it's always possible to discuss what the work is "about" on two separate levels: the more concrete level of the plot (i.e., what literally happens in the work), as well as the more abstract level of the theme (i.e., the concepts that the work deals with). Understanding the themes of a work is vital to understanding the work's significance—which is why, for example, every LitCharts Literature Guide uses a specific set of themes to help analyze the text.

Although some writers set out to explore certain themes in their work before they've even begun writing, many writers begin to write without a preconceived idea of the themes they want to explore—they simply allow the themes to emerge naturally through the writing process. But even when writers do set out to investigate a particular theme, they usually don't identify that theme explicitly in the work itself. Instead, each reader must come to their own conclusions about what themes are at play in a given work, and each reader will likely come away with a unique thematic interpretation or understanding of the work.

Symbol, Motif, and Leitwortstil

Writers often use three literary devices in particular—known as symbol , motif , and leitwortstil —to emphasize or hint at a work's underlying themes. Spotting these elements at work in a text can help you know where to look for its main themes.

• Near the beginning of Romeo and Juliet , Benvolio promises to make Romeo feel better about Rosaline's rejection of him by introducing him to more beautiful women, saying "Compare [Rosaline's] face with some that I shall show….and I will make thee think thy swan a crow." Here, the swan is a symbol for how Rosaline appears to the adoring Romeo, while the crow is a symbol for how she will soon appear to him, after he has seen other, more beautiful women.
• Symbols might occur once or twice in a book or play to represent an emotion, and in that case aren't necessarily related to a theme. However, if you start to see clusters of similar symbols appearing in a story, this may mean that the symbols are part of an overarching motif, in which case they very likely are related to a theme.
• For example, Shakespeare uses the motif of "dark vs. light" in Romeo and Juliet to emphasize one of the play's main themes: the contradictory nature of love. To develop this theme, Shakespeare describes the experience of love by pairing contradictory, opposite symbols next to each other throughout the play: not only crows and swans, but also night and day, moon and sun. These paired symbols all fall into the overall pattern of "dark vs. light," and that overall pattern is called a motif.
• A famous example is Kurt Vonnegut's repetition of the phrase "So it goes" throughout his novel Slaughterhouse Five , a novel which centers around the events of World War II. Vonnegut's narrator repeats the phrase each time he recounts a tragic story from the war, an effective demonstration of how the horrors of war have become normalized for the narrator. The constant repetition of the phrase emphasizes the novel's primary themes: the death and destruction of war, and the futility of trying to prevent or escape such destruction, and both of those things coupled with the author's skepticism that any of the destruction is necessary and that war-time tragedies "can't be helped."

Symbol, motif and leitwortstil are simply techniques that authors use to emphasize themes, and should not be confused with the actual thematic content at which they hint. That said, spotting these tools and patterns can give you valuable clues as to what might be the underlying themes of a work.

Thematic Concepts vs. Thematic Statements

A work's thematic concept is the broader topic it touches upon—for instance:

• Forgiveness

while its thematic statement is the particular argument the writer makes about that topic through his or her work, such as:

• Human judgement is imperfect.
• Love cannot be bought.
• Getting revenge on someone else will not fix your problems.
• Learning to forgive is part of becoming an adult.

Should You Use Thematic Concepts or Thematic Statements?

Some people argue that when describing a theme in a work that simply writing a thematic concept is insufficient, and that instead the theme must be described in a full sentence as a thematic statement. Other people argue that a thematic statement, being a single sentence, usually creates an artificially simplistic description of a theme in a work and is therefore can actually be more misleading than helpful. There isn't really a right answer in this debate.

In our LitCharts literature study guides , we usually identify themes in headings as thematic concepts, and then explain the theme more fully in a few paragraphs. We find thematic statements limiting in fully exploring or explaining a the theme, and so we don't use them. Please note that this doesn't mean we only rely on thematic concepts—we spend paragraphs explaining a theme after we first identify a thematic concept. If you are asked to describe a theme in a text, you probably should usually try to at least develop a thematic statement about the text if you're not given the time or space to describe it more fully. For example, a statement that a book is about "the senselessness of violence" is a lot stronger and more compelling than just saying that the book is about "violence."

Identifying Thematic Statements

One way to try to to identify or describe the thematic statement within a particular work is to think through the following aspects of the text:

• Plot: What are the main plot elements in the work, including the arc of the story, setting, and characters. What are the most important moments in the story? How does it end? How is the central conflict resolved?
• Protagonist: Who is the main character, and what happens to him or her? How does he or she develop as a person over the course of the story?
• Prominent symbols and motifs: Are there any motifs or symbols that are featured prominently in the work—for example, in the title, or recurring at important moments in the story—that might mirror some of the main themes?

After you've thought through these different parts of the text, consider what their answers might tell you about the thematic statement the text might be trying to make about any given thematic concept. The checklist above shouldn't be thought of as a precise formula for theme-finding, but rather as a set of guidelines, which will help you ask the right questions and arrive at an interesting thematic interpretation.

Theme Examples

The following examples not only illustrate how themes develop over the course of a work of literature, but they also demonstrate how paying careful attention to detail as you read will enable you to come to more compelling conclusions about those themes.

Themes in F. Scott Fitzgerald's The Great Gatsby

Fitzgerald explores many themes in The Great Gatsby , among them the corruption of the American Dream .

• The story's narrator is Minnesota-born Nick Caraway, a New York bonds salesman. Nick befriends Jay Gatsby, the protagonist, who is a wealthy man who throws extravagant parties at his mansion.
• The central conflict of the novel is Gatsby's pursuit of Daisy, whom he met and fell in love with as a young man, but parted from during World War I.
• He makes a fortune illegally by bootlegging alcohol, to become the sort of wealthy man he believes Daisy is attracted to, then buys a house near her home, where she lives with her husband.
• While he does manage to re-enter Daisy's life, she ultimately abandons him and he dies as a result of her reckless, selfish behavior.
• Gatsby's house is on the water, and he stares longingly across the water at a green light that hangs at the edge of a dock at Daisy's house which sits across a the bay. The symbol of the light appears multiple times in the novel—during the early stages of Gatsby's longing for Daisy, during his pursuit of her, and after he dies without winning her love. It symbolizes both his longing for daisy and the distance between them (the distance of space and time) that he believes (incorrectly) that he can bridge. 
• In addition to the green light, the color green appears regularly in the novel. This motif of green broadens and shapes the symbolism of the green light and also influences the novel's themes. While green always remains associated with Gatsby's yearning for Daisy and the past, and also his ambitious striving to regain Daisy, it also through the motif of repeated green becomes associated with money, hypocrisy, and destruction. Gatsby's yearning for Daisy, which is idealistic in some ways, also becomes clearly corrupt in others, which more generally impacts what the novel is saying about dreams more generally and the American Dream in particular. 

Gatsby pursues the American Dream, driven by the idea that hard work can lead anyone from poverty to wealth, and he does so for a single reason: he's in love with Daisy. However, he pursues the dream dishonestly, making a fortune by illegal means, and ultimately fails to achieve his goal of winning Daisy's heart. Furthermore, when he actually gets close to winning Daisy's heart, she brings about his downfall. Through the story of Gatsby and Daisy, Fitzgerald expresses the point of view that the American Dream carries at its core an inherent corruption. You can read more about the theme of The American Dream in The Great Gatsby here .

Themes in Chinua Achebe's Things Fall Apart

In Things Fall Apart , Chinua Achebe explores the theme of the dangers of rigidly following tradition .

• Okonkwo is obsessed with embodying the masculine ideals of traditional Igbo warrior culture.
• Okonkwo's dedication to his clan's traditions is so extreme that it even alienates members of his own family, one of whom joins the Christians.
• The central conflict: Okonkwo's community adapts to colonization in order to survive, becoming less warlike and allowing the minor injustices that the colonists inflict upon them to go unchallenged. Okonkwo, however, refuses to adapt.
• At the end of the novel, Okonkwo impulsively kills a Christian out of anger. Recognizing that his community does not support his crime, Okonkwo kills himself in despair.
• Clanswomen who give birth to twins abandon the babies in the forest to die, according to traditional beliefs that twins are evil.
• Okonkwo kills his beloved adopted son, a prisoner of war, according to the clan's traditions.
• Okonkwo sacrifices a goat in repentence, after severely beating his wife during the clan's holy week.

Through the tragic story of Okonkwo, Achebe is clearly dealing with the theme of tradition, but a close examination of the text reveals that he's also making a clear thematic statement that following traditions too rigidly leads people to the greatest sacrifice of all: that of personal agency . You can read more about this theme in Things Fall Apart   here .

Themes in Robert Frost's The Road Not Taken

Poem's have themes just as plot-driven narratives do. One theme that Robert Frost explores in this famous poem,  The Road Not Taken ,  is the illusory nature of free will .

• The poem's speaker stands at a fork in the road, in a "yellow wood."
• He (or she) looks down one path as far as possible, then takes the other, which seems less worn.
• The speaker then admits that the paths are about equally worn—there's really no way to tell the difference—and that a layer of leaves covers both of the paths, indicating that neither has been traveled recently.
• After taking the second path, the speaker finds comfort in the idea of taking the first path sometime in the future, but acknowledges that he or she is unlikely to ever return to that particular fork in the woods.
• The speaker imagines how, "with a sigh" she will tell someone in the future, "I took the road less travelled—and that has made all the difference."
• By wryly predicting his or her own need to romanticize, and retroactively justify, the chosen path, the speaker injects the poem with an unmistakeable hint of irony .
• The speaker's journey is a symbol for life, and the two paths symbolize different life paths, with the road "less-travelled" representing the path of an individualist or lone-wolf. The fork where the two roads diverge represents an important life choice. The road "not taken" represents the life path that the speaker would have pursued had he or she had made different choices.

Frost's speaker has reached a fork in the road, which—according to the symbolic language of the poem—means that he or she must make an important life decision. However, the speaker doesn't really know anything about the choice at hand: the paths appear to be the same from the speaker's vantage point, and there's no way he or she can know where the path will lead in the long term. By showing that the only truly informed choice the speaker makes is how he or she explains their decision after they have already made it , Frost suggests that although we pretend to make our own choices, our lives are actually governed by chance.

What's the Function of Theme in Literature?

Themes are a huge part of what readers ultimately take away from a work of literature when they're done reading it. They're the universal lessons and ideas that we draw from our experiences of works of art: in other words, they're part of the whole reason anyone would want to pick up a book in the first place!

It would be difficult to write any sort of narrative that did not include any kind of theme. The narrative itself would have to be almost completely incoherent in order to seem theme-less, and even then readers would discern a theme about incoherence and meaninglessness. So themes are in that sense an intrinsic part of nearly all writing. At the same time, the themes that a writer is interested in exploring will significantly impact nearly all aspects of how a writer chooses to write a text. Some writers might know the themes they want to explore from the beginning of their writing process, and proceed from there. Others might have only a glimmer of an idea, or have new ideas as they write, and so the themes they address might shift and change as they write. In either case, though, the writer's ideas about his or her themes will influence how they write. 

One additional key detail about themes and how they work is that the process of identifying and interpreting them is often very personal and subjective. The subjective experience that readers bring to interpreting a work's themes is part of what makes literature so powerful: reading a book isn't simply a one-directional experience, in which the writer imparts their thoughts on life to the reader, already distilled into clear thematic statements. Rather, the process of reading and interpreting a work to discover its themes is an exchange in which readers parse the text to tease out the themes they find most relevant to their personal experience and interests.

Themes in Literature

Have you ever put down a book and wondered, what in the world did that mean ? Chances are, the author didn’t have a clearly defined theme worked out, or didn’t execute it well.

What is Theme?

Theme definition – literature.

A literary theme is the unifying or dominant idea in a work of fiction. This is not to be confused with the plot. The theme is the main topic or central idea. This can be as simple as “love,” “family,” or “revenge.” It can be as complicated as “science vs. nature,” “the folly of youth,” or “the treachery of commerce.”

Every writer makes his or her writing about something, and that something, the essence of the story, is the theme.

Example of Theme in a Story

For example, a major theme in Great Expectations is that moral values are more important than wealth and status. Alienation is a primary theme in Crime and Punishment , while “true love triumphs” dominates the well-loved classic, Princess Bride .

What good does it do to know major themes? We’ve already pointed out how a story without a uniting theme is often confusing and leaves the reader wanting more. Well, learning about themes isn’t just a way to better analyze an author’s finished work of fiction. It’s also a way to improve your own writing. The stronger a writer’s theme is, and the more in tune the writer is with that theme’s execution, the better the work as a whole will be.

For your own written work, ask yourself: what, under all the characters and subplots, is my story really about? Is it about love conquering all? About good triumphing over evil? About the dangers of progress? Often, your story will have a “ spine .” This is a one-sentence description of the heart behind your book. For example, one could say the “spine” of Pride and Prejudice is “a man and woman in the regency era overcome their preconceptions to ultimately find love” while two major themes are matrimony and, you guessed it, prejudice.

This might sound too simple, but that’s okay. The theme is supposed to be an oversimplification of the story’s meaning.

Once you’ve defined your theme and the spine of your story, it’s helpful to look at all your characters, situations, and plot developments through this lens. Say your theme is “love fails in the end.” Even at the happiest moments of your love story, it might be wise to include some foreshadowing of love’s imminent doom. This helps enrich your writing.

Two of the primary ways to build a theme in writing are through motifs and symbols . A motif is a recurring literary structure that helps develop your theme. It’s a meaningful pattern that reuses objects, characters, even weather, to further emphasize the theme.

For example, in The Great Gatsby , changing weather patterns reflect the shifting tone of the story. The weather is overwhelmingly hot when characters feel suffocated by a situation, tension is connected to storms, and the day of Gatsby’s funeral it’s pouring rain.

A symbol is like a motif, but on a smaller scale. It’s an image, character, or object that has a meaning beneath the immediate surface. Let’s stick with The Great Gatsby in our explanation. In the novel, Gatsby is still in love with a former flame, Daisy. He’s come up in the world since their last meeting, and now lives across the lake from her in an enormous mansion. Daisy has a green light on the edge of her dock, and Gatsby watches that light from the edge of his own dock. This is an example of symbolism. There’s nothing to suggest Gatsby is particularly infatuated with green lights, but for him the light symbolizes Daisy, who seems to him unattainable.

In summary, a literary theme is different than a plot. While a plot is the order of events in a work of fiction, the theme involves the overall meaning and purpose of the book. The theme is where fiction intersects with life. It may be a story about hobbits in Middle Earth, but the theme of friendship and good conquering evil is still applicable in real life.

Thanks for watching, and I’ll see you next time.

What's a Literature Review? 

A literature review (or "lit review," for short) is an in-depth critical analysis of published scholarly research related to a specific topic. Published scholarly research (aka, "the literature") may include journal articles, books, book chapters, dissertations and thesis, or conference proceedings. 

A solid lit review must:

• be organized around and related directly to the thesis or research question you're developing
• synthesize results into a summary of what is and is not known
• identify areas of controversy in the literature
• formulate questions that need further research

This was very helpful Jes! Thanks a lot.

We're glad you found this post helpful, Eniale!

Thank you Jes. I found your method to thematic literature review very useful and easy to understand. I am a Phd student in Education with the University of Durban.I am based in Zimbabwe.

We are glad you found this method useful!

I am having difficulties locating an example of a completed literature review outline. Where would I find additional examples? Thank you.

You’re welcome!

Hi is literature review writing same as writing a thematic summary after reading articles based on the given topic?

Great question! It depends on the assignment (what faculty want with the thematic summary assignment). For literature reviews, paragraphs revolve around themes within the literature as opposed to authors. So, when Jes uses the phrasing, "thematic literature reviews," she is referring to how literature reviews are about synthesizing themes across the literature as opposed to creating paragraphs that are summaries for each singular author/ source. You can read more about synthesis on our website http://bit.ly/2JEUK09

thank you, this one is useful.

I've been in a slump for weeks regarding a literature review assignment. This is very very helpful! Thank you!

We're happy this helped! Good luck with your literature review!

I'm doing a lit review for a post grad certificate and I have to discuss the findings using a framework analysis, can you lead me to the right section. Yours struggling

Hello, You might check with your professor regarding what is meant by “framework analysis” in relation to the finding of your literature review. While the Writing Center has some sources on components of writing literature reviews, it is best to speak with faculty regarding assignment specifics. You might also check out our page on literature reviews: https://academicguides.waldenu.edu/writingcenter/assignments/literaturereview We hope this helps!

i have found it useful, it has polished me some how, my problem in the literature review is how to formulate themes and subthemes for the topic. forexample dealing with solid waste skips monitoring and management for municpalities. what themes can i build on in the study. thank you dear.

Hello! I think creating an outline my help you identify some main themes and sub themes and then you can choose what themes and sub themes you want to focus on from there. You might check out our outlining page for tips on creating an outline: http://bit.ly/2WP3UCe. We hope this helps!

Thank you! My professor referenced this link/article for the literature review assignment in a research class. This was helpful.

So glad you found it helpful! Thank you for commenting!

This really was helpful. I feel so much better about tackling my lit review now. Thanks!

Helping writers gain confidence in their skills is one of our primary goals for this blog. Thank you for reaching out with this kind note to let us know we are on the right track! :)

Really informative study. It helped me in finding themes in literature. Plz if u can give me your email. It will be very helpful to me in writing my dissertation

This was very helpful; clear and concise. Thank you!

Oh Jes! you just sent me back to the drawing board, guilty of annotated bibliography. Thank you for this helpful writeup.

I'm sure you're not alone! And there is a reason this is a blog post topic. :) Kudos for identifying potential issues in your own writing and thank you so much for reading and commenting!

im failing to understand the concept themes

This can be a tricky concept to grasp, which is why we've created blog posts like this one. Basically, "themes" are ideas that connect so that writers are organizing based on themes rather than on sources. So instead of having one paragraph about one article, another paragraph about a different article, and a third paragraph about a third article, the paragraphs would be organized based on common ideas shared between two or three of the articles. You might check out our MEAL plan resources (https://academicanswers.waldenu.edu/faq/72800), or our resources for synthesis (https://academicanswers.waldenu.edu/faq/72694) for further clarification. Hope this helps! Thanks for reading!

Metrics details

A Strategic Guiding Council (SGC) was created within a Family Carer Decisions Support study, to engage family carers of persons with advanced dementia as advisors to inform the design and implementation of the study. The SGC consists of an international group of family advisors from Canada, the Republic of Ireland, the United Kingdom, the Netherlands, and the Czech Republic. There are limited studies that have explored the integration of Patient and Public Involvement (PPI) in dementia research, end-of-life care and long-term care. Therefore, this study explores PPI engagement in health research with family carers to understand further their interest in being involved in the SCG within the FCDS intervention which is focused on supporting caregivers to make decisions about end-of-life care for residents with advanced dementia.

This study utilized an interpretive descriptive design and explored the motivations of ten family advisors from Canada, the Republic of Ireland, the United Kingdom, and the Netherlands in being part of the SGC. Semi-structured interviews were conducted by phone or videoconferencing and were recorded, transcribed, and analyzed using thematic analysis.

Three themes generated from the findings of the study were (1) engaging in reciprocal learning; (2) using lived experience to support other family carers; and (3) creating a collective momentum for advocacy and change.

Conclusions

Family carers motivations to being part of the SCG was driven by their intent to help carers navigate the health system and to create a psychosocial support system for other carers experiencing end-of-life with their loved ones. Being part of the SCG provided a benefit to family carers which provided a venue for them to contribute meaningful information from their experience, learn from other health professionals, research and other advisors and an avenue for advocacy work to improve access to end-of-life care supports through education. To our knowledge, this is the first study that explores the motivations of an international group of family advisors’ engagement in health research to promote integration of a palliative approach to dementia care in long-term care homes. This study further contributes to the literature from an international perspective the importance of PPI in research. Further research is warranted that explores PPI in research to improve access to end-of-life supports.

Plain English summary

Patient and public involvement (PPI) in research has been growing worldwide and ensures that research conducted is relevant to the needs of patients. Within the Family Carer Decisions Support study, we created a Strategic Guiding Council (SGC) to engage family carers of persons with advanced dementia as advisors to improve access to a palliative approach to care. The SGC includes family advisors from Canada, the Republic of Ireland, the United Kingdom, the Netherlands, Italy and the Czech Republic. The goal of the strategy was to engage with family advisors in research activities to improve access to a palliative approach and quality of care provided to people with dementia receiving end-of-life care. Including patients and family in research is extremely important, therefore our aim in this study was to explore family advisors’ motivations to engaging in the SGC. Family advisors reported encountering challenges with navigating the health system with end-of-life care and they chose to participate in the SGC to support other carers who are experiencing a similar situation. Being part of the SGC also provided the family advisors with an avenue to advocate on the importance of improving access to end-of-lifesupports and the opportunity to learn from other advisors, health professionals and researchers.

Peer Review reports

Introduction

Patient and Public Involvement (PPI) in research has been growing internationally due to efforts to ensure that health research is relevant, meaningful and impactful for patients and the public [ 1 ]. PPI ensures studies are focused on patient-identified priorities and encourages patients and their family/friends to be proactive partners in all stages of the research process: study design, intervention implementation, interpretation and developing of findings and knowledge translation [ 2 , 3 ]. PPI values a person’s lived experience and reported benefits include improvement in patient experiences, high quality health care and ensuring research funding is allocated to studies that are relevant and deemed a priority to patients and the public [ 4 , 5 ]. Most importantly, PPI ensures that work is being carried out with or by members of the public, rather than for them or about them.

The inclusion of PPI in health research has been deemed a priority in many countries [ 6 ]. The United Kingdom has made PPI participation a requirement to increase community involvement in health service planning and decision making in the delivery of health initiatives and research [ 6 ]. Similarly, in Canada, the Canadian Institute for Health Research (CIHR) developed partnerships with funding agencies to develop a Strategy for Patient-Oriented Research to improve health outcomes by promoting the engagement of patients and focusing on priorities identified by patients [ 7 ]. PPI has been studied in stroke care [ 8 ], dialysis [ 9 ], mental health research [ 10 ] and has been growing within dementia research [ 11 ]. Findings from the Bethell et al. (2018) scoping review discussed the importance of collective learning from people with lived experience with dementia and reinforced the importance of challenging societal views that portray people with dementia as not fully capable of participating in research [ 11 ]. Although there is broad consensus on the importance of integrating PPI in health research, further research is warranted to explore the integration of PPI in dementia research, long term care (LTC) and end-of-life care to improve health outcomes for older adults living with dementia and their family carers through meaningful engagement in health research.

In order to improve the quality, relevance and uptake of research amongst family carers, PPI engagement was integrated within the Family Carer Decision Support (FCDS) mySupport study [ 12 , 13 , 14 ]. The FCDS intervention focused on supporting caregivers to make decisions about end-of-life care for residents with advanced dementia. Introducing a palliative approach to care promotes a comprehensive person-centered approach to care for residents during end-of-life through advance care planning, management of disease symptoms, psychosocial and spiritual care and bereavement support [ 15 ]. The FCDS study was implemented in Canada, the Republic of Ireland, the United Kingdom, the Netherlands, Czech Republic, and Italy during the COVID-19 pandemic. An international PPI panel, called The Strategic Guiding Council, was formed early on to help inform the design, implementation and evaluation of the FCDS intervention by advising the research team and sharing their experiences in caring for individuals living with advanced dementia in LTC. There were 15 people involved in the Strategic Guiding Council. These individuals met via Zoom at quarterly Strategic Guiding Council meetings. They were involved in reviewing draft intervention components such as the comfort care booklet, providing assistance in interpreting study findings, and offering recommendations for knowledge translation and dissemination activities [ 16 , 17 ].

To our knowledge, there are currently no research studies that have explored PPI engagement in health research within an international Strategic Guiding Council. In addition, there is little information in the literature that discusses how to engage and involve families in LTC research [ 18 , 19 ]. Meaningful engagement with family carers is an important area to focus on in research as it provides researchers with a unique perspective of their lived experience which can also lead to an improvement in research questions, facilitate knowledge transfer and promote trust [ 18 , 20 ]. Therefore, this qualitative study aimed to contribute to the literature on PPI engagement with family carers by exploring the motivations of family carers to become family advisors on the Strategic Guiding Council. It is imperative to explore the motivations of family carers in research for recruitment and retention purposes as they are important members of the research team who can provide feedback on the practicality and relevance of interventions. The research question was: What are family advisors’ motivations in working with a Strategic Guiding Council and research team to promote integration of a palliative approach to dementia care in LTC homes?

This study utilized Sally Thorne’s (2016) interpretive description methodology to address the research question. Interpretive description is grounded in a naturalistic inquiry and objective knowledge is unattainable through empirical analysis but rather, the participants and researcher construct meaning together [ 21 ]. Interpretive descriptive is known as a useful methodology to generate knowledge for health service research due to its focus on experiential knowledge and exploring human commonalities and differences [ 21 ]. This approach was suitable for this study to reflect on the diverse experiences of family carers in supporting persons living with dementia which shaped their motivations to engage in research as family advisors.

Convenience sampling [ 22 ] was used to locate participants who were interested in being a member of the Strategic Guiding Council to advise the FCDS study and share their viewpoint as family carers for individuals living with advanced dementia. Specifically, they met the following inclusion criteria: (a) family carer of a person with advanced dementia (living or passed away in the last five years); (b) 16 years of age or older; and (d) comfortable communicating in English.

Recruitment

Recruitment for the Strategic Guiding Council consisted of both passive and active recruitment strategies. We attempted to recruit participants from all six countries involved in the FCDS intervention, however we were unable to recruit family carers from Italy and the Czech Republic due to language barriers. Hence, we ended up with family carers from four of the six participating countries: Canada, United Kingdom, the Republic of Ireland and the Netherlands. The recruitment of family advisors to join the Strategic Guiding Council and research study was conducted through the completion of an Expression of Interest Form and country-specific recruitment flyer, which were posted at local organizations (i.e., LTC homes) for a period of two months between June to August 2020. The Expression of Interest Form and the Country-Specific Recruitment Flyers were also posted on the mySupport website. Family carers who were interested in participating in the Strategic Guiding Council completed the Expression of Interest Forms and once completed, the PPI study coordinator, along with the country-specific research representative, contacted eligible individuals who met the inclusion criteria.

Active recruitment strategies for the study consisted of staff working in LTC homes or nursing homes to share information to family carers regarding the Strategic Guiding Council and mySupport study following a recruitment script guideline developed by the research team. Verbal permission was sought from the family carers to have their contact information shared with the research team to discuss the Strategic Guiding Council and mySupport study further. A telephone or email recruitment script was used by research staff to inform interested family carers about the study, answer any questions and affirm their continued interest to participate. Family carers that provided consent to be part of the Strategic Guiding Council as family advisors were provided with an orientation, which was conducted by the PPI coordinator or the country-specific research representative either in-person or virtually. Two family advisors were included in this manuscript as co-authors as they contributed to writing and reviewing the manuscript.

Data collection

Demographic data such as country of residence, sex, age, and relationship to person living with dementia were collected electronically using LimeSurvey. Semi-structured interviews were conducted by the PPI coordinator or by the country specific research representative either on the telephone or Zoom videoconference platform based on participants’ preference from September 2020–2021. The interviewers were master’s prepared or graduate students in the field of nursing and health studies. Interviews were scheduled based on their preference for time in their respective time zones and within the first three months of joining the Strategic Guiding Council. Interviews were conducted in English and the country specific research coordinator was available to assist participants with translation support as a ‘buddy’. Participants took part in an interview in a quiet, private location of their choosing such as in their home. An interview guide was used to explore family carers’ motivation in working with a Strategic Guiding Council and research team and developed through a review of the literature for PPI concepts. Examples of interview questions were: What is your experience with palliative care? What is your experience working with research and what about your experience working on a panel or a committee? What is your understanding of a Strategic Guiding Council? The interviews lasted 30 to 40 min and were audio-recorded and transcribed verbatim. Identifying information was removed and transcripts were reviewed against the recording for accuracy [ 23 ]. Participants’ identity was protected throughout the study and all study information that was recorded, transcribed and analyzed were kept in a locked cabinet or stored in a password protected, encrypted file.

Data analysis

Demographic data were analyzed using counts for categorical data and means and standard deviations (SD) for continuous data. The first stage of data analysis consisted of “sorting and organizing” [21 pp 156] the data by reading the transcripts. In the second stage, “making sense of pattern” [21 pp 163], the authors (SL and JK) analyzed two transcripts independently and generated a code list and themes. The authors (SL and JK) met together and discussed their preliminary findings. Descriptive codes were merged to develop themes or groupings [ 21 ]. The findings were then discussed with additional research team members (SV, VM and SK) and themes were defined based on consensus. Once consensus was gained within the research team, SL proceeded with analyzing the remaining transcripts using Dedoose qualitative software. For the final stage, “transforming pattern into findings” [21 pp 173] the author SL met frequently with the research team during data analysis to review the findings and themes generated. The final written conceptualization of the findings was reviewed by the research team and presented in this study [ 21 ].

Ethical considerations

This study was approved by local research ethics board (#5837). Research was conducted following the standards outlined by the Tri- Council Policy Statement for Ethical Conduct for Research Involving Humans [ 24 ]. Written and verbal informed consent was sought from all participants with the understanding that their participation in the study would not influence them or their relatives care at the LTC home. Each participant had experience as a family carer for a relative with dementia and due to this, were sensitive to emotional reactions. Therefore, the sensitive interviewing techniques were employed, which included validation of emotions and experiences of the interviewer, frequent breaks and if needed, discontinuation of the interview.

Rigour and trustworthiness

Several strategies were employed by the research team to enhance trustworthiness and rigour in the study. The research team participated in co-constructing knowledge by interpreting participants experiences from the semi-structured interviews. Researcher triangulation was achieved by meeting frequently with the research team to discuss data analysis and themes developed. Engaging in triangulation allowed the researcher to confirm constructed perception of an event or process [ 21 ]. An audit trial was maintained by the primary author to establish confirmability of the research findings and ensure the findings are based on participants responses instead of the researchers’ own preconceptions and biases.

Characteristics of sample

A total of 10 family advisors shared their perspectives in being part of the Strategic Guiding Council for the mySupport Family Carer Decision Support Study. There was representation from four countries, Canada ( n  = 4), United Kingdom ( n  = 1), the Netherlands ( n  = 1), and the Republic of Ireland ( n  = 4). Demographics were missing for some advisors ( n  = 5). Half of the advisors were female ( n  = 5). The mean age of advisors was 65.6 years (SD = 5.0) and most were caring for a spouse or parent. Most of the advisors reported having education at the post-secondary level (i.e., college, bachelor’s degree, masters).

Overview of findings

Three themes represented the family advisors’ motivation in engaging with the Strategic Guiding Council: (1) engaging in reciprocal learning; (2) using lived experience to support other family carers ; and (3) creating a collective momentum for advocacy and change.

Theme 1. Engaging in reciprocal learning

This first theme explains how family advisors were motivated to be engaged with the Strategic Guiding Council and research team to help and also learn about health and social services from other care partner experiences. This was identified by one advisor who shared: “I have experiences that might be valuable, but other people on the council may have experiences that could help me as well” (P2, Canada). A family advisor expressed that engaging with health professionals on the research team (e.g., nurses, physicians, social workers) allowed for reciprocal learning, where the care partner learned from the health professional and the health professional had the chance to learn from caregivers:

I also very much enjoy the interaction of working with professionals [health]. I love the learning experience that both of us can get and ultimately again as we discussed before, what I learn I can then take back to the people who can gain the most from what I learn. Which are the people suffering the condition. (P5, United Kingdom)

By engaging with the Strategic Guiding Council, participants mentioned that it provided them with the opportunity to learn about interventions and programs that are happening in other countries. Family advisors further endorsed that being involved with the Strategic Guiding Council, not only did it promote reciprocal learning between the caregiver and healthcare team, it also allowed family advisors to be active participants in their loved one’s care and not “only visitors” (P6, The Netherlands).

Theme 2. Using lived experience to support other family carers

This theme describes the participants’ lived experience as a family carer of a person with dementia and how their experience was a driver for engaging with the Strategic Guiding Council. Based on their own experiences, family advisors expressed a strong desire to create a circle of moral and psychosocial support system for other carers. Advisors endorsed that their personal experience with a loved one gave them “the drive to do something” (P10, the Republic of Ireland). This revealed how they reflected on their previous experiences in supporting persons with dementia to inform necessary changes for other family carers. The advisor further elaborated: “I thought for anybody that’s going through it, you know I’m going to try and do something to help improve this”. This sentiment was further expressed by another participant:

I think just giving my personal experience that I’ve had in Long Term Care. I watched how my father lived and how his end of life was and just want to help in any way that I can for other families going through such a difficult time. (P1, Canada)

Family advisors expressed experiencing challenges with obtaining appropriate end-of-life care for their loved one due to clinicians working in care homes limited knowledge regarding a palliative approach to care, which contributed to negative experiences. One participant mentioned, “My mom’s GP [general practitioner] denied her Palliative Care because he said she didn’t have Cancer” (P9, The Republic of Ireland). The advisor further attributed that the lack of information from the physician led to feelings of frustration but then ‘sparked something within’, which led the participant to determine that: “rather than fighting the system, I educated myself. I just decided I would speak out and tell mom’s story to change those mistakes and hopefully make a difference” (P9, The Republic of Ireland)

Another advisor expressed a similar situation where she experienced challenges with her husband receiving adequate pain management despite advocating on his behalf to stakeholders in his long-term care home and physician. The advisor shared:

With my husband, the home didn’t know anything about Palliative Care and we became increasingly desperate because he was having such terrible pain. Awful pain, and it was just awful to see his body twisting. I was so desperate. I tried to get him into a hospice and they had no beds and I turned to the Palliative Care nursing team that cover residents around the country side and towns. They said they can’t come in and help unless they are asked to by the GP that covers the residential home and I asked him [GP] and he wouldn’t speak to me. (P5, United Kingdom)

After advocating on behalf of her husband for adequate end-of-life care, the advisor further shared:

It was only the day before he died that he was completely pain free. The last few days of his life he had some pain control. That shouldn’t have happened, he should have had pain control months before, or weeks before he became in such a terrible state. That’s why I’m desperate that it doesn’t happen to other people. (P5, United Kingdom)

Although many family advisors shared negative experiences with end-of-life care, an advisor described end-of-life care as a “beautiful, worthwhile thing to be a part of” (P2, Canada). She further describes how end-of-life care has been a large part of her life since she was a caregiver to family members who passed away in LTC. Therefore, she hopes to be able to help others going through a difficult moment by sharing her experience:

It’s worthwhile to be able to share the things you know and share your experience with families to have when they are facing this end-of-life care phase. It’s a really difficult circumstance to be in and it’s very complex it’s nothing that you can rehearse for… I think that my experience could be valuable to other people. (P2, Canada)

A strong motivating factor that led advisors to engage with the Strategic Guiding Council and research team was to help others navigate the health system. Advisors expressed encountering challenges navigating the health system to ensure that their family member with dementia was provided with the treatment that they needed. Many endorsed a motivation to be engaged with the Strategic Guiding Council was to help other caregivers navigate the health system. An advisor shared: "I think it is in helping people find their way through different systems … as they begin to navigate it and know the important things to look for and what things to just let go" (P4, Canada).

In addition, an advisor also learned from her experience that it is important to seek help early on and engage in discussions about dying early on in a person’s care until they are at the end-of-life. She shared:

My mission is that what happened to my husband never happens to other people. They get to that stage and understand and get help quickly … definitely get help early on and leave it sort of until its Palliative and it can’t be controlled. They need to know earlier on. (P5, United Kingdom)

A family advisor further described supporting a family member with dementia as the power of attorney and described the process as not black or white. The advisor disclosed the challenges and complexities of being power of attorney, especially in relation with capacity of understanding concerns. Supporting families navigate these concerns was a motivating factor for the advisor to join the Strategic Guiding Council. One advisor expressed: “To think that I could help family members understand what might be ahead of them, I thought was interesting and useful…so that was the motivation” (P8, The Republic of Ireland). Overall, participants identified the importance of sharing their knowledge and experience as a means of enlightening others and helping other carers in their caregiving journey.

Theme 3. Creating a collective momentum for advocacy and change

This theme describes the importance of advocacy to improve access to palliative care supports and education to reduce stigma in end-of-life care. Family advisors are motivated to be engaged with the Strategic Guiding Council to be able to use their voice to improve the quality of care provided to individuals with dementia and use their voices to “support or influence the direction of the program (P7, The Republic of Ireland). An advisor shared:

Advocate for elderly people to have Comfort Care, even if it is not in the last part of their lives. They have to have Comfort Care even when the disease of Dementia comes, to have all the people around you and try to make the life of the person as comfortable as can be. (P6, The Netherlands)

An advisor shared how being involved in their loved ones care brought fulfillment in their life through the advocacy work they are engaged in:

I look back now and I think it’s probably the best thing I have achieved in my life. Plus, it’s opened up my world to meeting amazing people. Like even now talking to you today [researcher], like if mom hadn’t come into my life, I wouldn’t be doing any of this [advocacy]. I don’t’ know what I’d be doing but I certainly wouldn’t’ be worrying about Dementia and end of life or having anything to do with it. It’s completely the opposite to what my life was. (P9, The Republic of Ireland)

Despite programs developed to bring more awareness regarding dementia care, advisors endorsed that there is still stigma that exists regarding dementia.

I don’t know about other countries but in the Republic of Ireland there’s not as much of a stigma as there was but there’s definitely still a stigma around Dementia or Alzheimer’s. There’s definitely huge education needed for the general public as well. It’s getting better. People are more aware, as well as there are more supports. But there’s still … you know, it’s one of those things that some people don’t want to talk about. (P10, The Republic of Ireland)

The Strategic Guiding Council was identified as an opportunity for advisors to be engaged in research initiatives and cross-country collaborations to improve integration of a palliative approach to care for individuals with dementia. An advisor who also had a long career in research shared:

I like the idea that it’s an international project and it will be interesting to see what the results are and also to make a difference for families that have family members or friends who have Dementia and reach end of life. It would be nice to make a difference if we can somehow. I like fairly efficient things, but I want to see some real impact you know collectively from this research project. I’ve been doing research for forty-five years so I know that lots of things take a long time to make a difference but I’d like to see some real outcomes from the research. (P3, Canada)

Through engagement in the Strategic Guiding Council and research team, a collective momentum for change can be made to improve the care being provided to people with dementia and provide person-centered care. An advisor emphasized the importance for health professionals to explore the wishes of the person with dementia and their family members to improve quality of life:

The nurses and the staff must be aware of the wishes of patients and family of the patients so they can be part of the last few times [moments] of the patient’s life and try to make it more about the person and family want to have and not the wishes of the organization to be efficien.t (P6, The Netherlands)

This study sought to explore the perspectives of family advisors’ motivations in working with a Strategic Guiding Council and research team to promote integration of a palliative approach to improve dementia care in LTC homes. To our knowledge, this is the first study which explores the perspectives of family carers motivations to participate in PPI research in an international Strategic Guiding Council, from four participating countries (Canada, United Kingdom, Republic of Ireland, and the Netherlands). The Strategic Guiding Council international study provided the advisors with an opportunity to be engaged in cross-country collaborations to improve end-of-life care for individuals with dementia and support the research team in determining opportunities to improve patient and family engagement.

The study findings are relevant to healthcare as it provides the perspectives of family carers motivation in being partners in care and research, which is an area of research that requires further exploration in LTC settings [ 18 ]. Involving family and patients in the development and implementation of research, enriches the relevance of the study by generating interventions that are sustainable and translatable to the community of interest [ 25 ]. PPI involvement is a growing area in health research and ensures that research is conducted in a manner that is relevant and meaningful to patients and the public [ 26 , 27 ]. Warner et al. [ 28 ] emphasizes the importance of involving patients and families in their care to ensure care reflects their needs and values. Through patient and family integration in the planning process, it can lead to positive patient end-of-life and family bereavement outcomes [ 28 ].

Family advisors in the study discussed how their lived experience providing care for a person with dementia was a motivating factor to wanting to be engaged with a Strategic Guiding Council and research team. Participants wanted to use their experience to help others who are going through difficult situations. Similar to the findings in our study, a study conducted by Cashin et al. [ 29 ] explored family’s motivation to being engaged in research and education development with health professionals, which was driven by their desire to improve their knowledge and promote awareness of dementia. Findings from the study are also consistent with family centered research that has been conducted in different disciplines. O’Keeffe et al. [ 30 ] explored family members motivation to being engaged in research in the field of adolescent mental health. A commonly cited motivation for being engaged with a research team was a desire to help others going through similar difficulties [ 30 ].

Advisors in the study discussed challenges with obtaining appropriate referral for end-of-life care or palliative treatment (i.e., pain management) for their loved one which was a driver for them to want to be engaged in a Strategic Guiding Council. Advisors reported stakeholders in care homes and health professionals limited knowledge regarding a palliative approach to care as a reason for experiencing challenges with obtaining a referral or treatment. This finding is consistent in the literature which discusses the need to expand education on end-of-life care amongst health professionals of all disciplines, patients and family [ 31 , 32 , 33 ]. In a study from Bolt et al. [ 34 ], the author emphasizes that nurses who provide care to people with dementia have a crucial role in identifying end-of-life needs and observing changes in clinical health status due to their frequent interactions with residents. However, it is imperative to explore effective education opportunities to promote capacity building within health professionals working in long-term care homes to provide a palliative approach to care to improve the health service delivery of older adults receiving end-of-life care.

PPI research is critical and it is imperative that researchers aim to achieve actionable outcomes with the participation of patients and public participation in research [ 11 ]. Advisors in the study disclosed how they want to be involved with the research team to be able to ‘see some real impact’ from the research projects they are engaged with. In a systematic review conducted by Domecq et al. [ 35 ], patient engagement in the planning and execution of research may improve its translation into clinical practice and may yield meaningful reports that’s written in a language that is understandable for participants and the community, thus supporting knowledge translation. Increasing participatory action research amongst patients and family to improve end-of-life careand dementia care may improve a person’s quality of life through the inclusion of individuals with lived experience to make program improvement recommendations [ 11 ]. Thus, reinforcing the importance of an interdisciplinary and unified approach to research.

Results from this study generated implications for research, policy, and practice. Research and policy implications generated from the study further emphasizes the importance of ensuring PPI is integrated in LTC settings and international research projects to further improve the implementation of a palliative approach to care within nursing homes and improve the quality of life of residents in the late phase of their illness. Advisors in the Strategic Guiding Council supported the FCDS study and were actively involved in creating guides for families and education materials along with the research team. Practice implications from the study reinforces the importance of involving family members in the decision-making process of their loved one’s goals of care during end of life. Families who are not provided the opportunity to discuss their relative’s illness, prognosis, and treatment experience difficulties with decision-making processes, feel uncertainty about the illness and may also feel unprepared for their relative’s death [ 31 ]. Exploring the motivations of family carers allowed the research team to engage family carers meaningfully by ensuring that their perspectives and lived experiences were incorporated in the FCDS research study. In addition, this study further contributes to the limited body of literature that explores PPI research amongst family caregivers in LTC [ 18 , 19 ].

Strengths and limitations

A major strength of this study is that the Strategic Guiding Council includes advisors from four countries with unique contexts with regards to healthcare systems and available services and presents findings PPI research within an international team. Additional study strengths include strategies to enhance trustworthiness of the study findings which consisted of meeting with the research team to engage in debriefing to ensure reflexivity and conformability with the research findings. The authors in the study also utilized triangulation to ensure rigour, which allowed for the confirmation of the findings and different perspective with the phenomena of interest [ 36 ]. Despite the research study utilizing a small sample of individuals from participating countries, this study offered an international perspective that explored the motivation of family advisors’ in working with a Strategic Guiding Council and research team which has not be explored before. Future qualitative research could include a large sample size and more countries beyond Canada and Europe. Advisors had to be comfortable in speaking in English, however a ‘buddy’ such as a research coordinator was assigned to those who required some translation. Despite the use of a ‘buddy’, due to limited time and resources we were unable to recruit family advisors in Italy and Czech Republic. Therefore, we were unable to include advisors in the study due to their limited proficiency in English. Future research should have measures in place to allow participants to take part in interviews in the language of their choosing. This study was also conducted during the COVID-19 pandemic and therefore future research should explore the impact of the pandemic with family caregivers’ participation in research. Additionally, the findings reinforce that family caregivers are motivated to be active participants in their loved ones care and want to be involved in meaningful work through research engagement. Therefore, researchers should aim to explore further family caregivers role in research to support in recruitment and to conduct meaningful research to improve health service delivery for patients.

This study contributed to the enrichment of literature by exploring PPI in research from an international perspective. Motivations that led to engagement with the Strategic Guiding Council and research team consisted of family advisors’ using lived experience to support other family carers and the motivation to engage in reciprocal learning with other care partners and research professionals. While many Family Advisors had strong motivations to be engaged with the Strategic Guiding Council and research team, many endorsed aspirations to support care partners navigate through the complexity of the health system and create a collective momentum for advocacy and change to improve end of life dementia care through their involvement with the Strategic Guiding Council.
