The matrix method for literature reviews.

This handout is available for download in DOCX format and PDF format .

What is the Matrix Method, and why should I use it?

Using a review matrix enables you to quickly compare and contrast articles in order to determine the scope of research across time. A review matrix can help you more easily spot differences and similarities between journal articles about a research topic. While they may be helpful in any discipline, review matrices are especially helpful for health sciences literature reviews covering the complete scope of a research topic over time. This guide focuses on the review matrix step in the literature review process and offers tips on how to use it effectively.

Organize your sources

Once you complete your research, organize your source by date in order to make it easier to see changes in research over time.

Begin by creating the blank matrix. The matrices can be easily constructed using table-making software such as Microsoft Excel, Word or OneNote, Google Sheets, or Numbers. Every review matrix should have the same first three column headings: (1) authors, title, and journal, (2) publication year, and (3) purpose.

Be aware that it may be difficult to determine purpose from just a cursory review of the article. In some cases, it may be necessary to first read the paper fully to identify its purpose.

Choose your remaining column topics

Next, carefully read all your articles. Note any important issues you identify. The following broad categories provide some suggestions for determining your own subject headings:

Methodological

Methodology is often an important question. For example, if you are looking at tests of an Ebola vaccine beyond human subjects, it will be important to note what type of animal the test was carried out on, i.e. macaques or mice.

Content-specific

Consider noting what was actually studied. For example, when looking at the effectiveness of traditional Chinese medicine in the treatment of illnesses, it would be important to note what illness was being studied.

Geographical

It may be important to note where the research was completed. For example, if you want to compare the effects of the AIDS epidemic in different countries, you would use country as a column heading.

There are many ways to choose your column headings, and these are just a few suggestions. As you create your own matrix, choose column headings that support your research question and goals.

• Do not include column headings that are explicit in your research question. For example, if you are looking at drug use in adolescents, do not include a column heading for age of study participants. If the answer will be the same for every study, it's generally a bad choice for a column heading.
• Do not try to fully complete a review matrix before reading the articles. Reading the articles is an important way to discern the nuances between studies.

Nursing Literature Reviews

What is a Literature (Lit) Review? 

A Literature Review is Not: 

• a quick summary of sources
• a grouping of broad, unrelated sources
• a compilation of everything that has ever been written on a topic
• a literature criticism or book review

So, what is it then?

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

Creating a Literature Review using the Matrix Method: 

A matrix review allows you to quickly compare and contrast articles in an easy to read format. It can help you to easily spot differences and similarities between journal articles and your nursing research topic. Review matrices are especially helpful for health sciences literature reviews that cover the scope of research over a given amount of time. 

Most literature reviews are set up in this format: 

Chart adapted from the book below: 

• Check out the e-book above for more help in creating a literature review matrix. 

Steps for Conducting a Literature Review

1. Choose Your Topic

• Review your PICO question and think about your central research question. To review the PICO process, please see Kerry Sewell's LibGuide on this subject. 

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? 

3. Select the databases you want to use to conduct your searches (See the Databases Tab Above!)

4. Conduct your searches and find the literature. (Keep track of your searches, try using the Search Strategy Lab Notebook!)

• Review the abstracts and conclusions carefully. This will help you decide which articles actually fit the criteria you are looking for. 
• Write down the keywords you used and where you found them. 
• You can also use RefWorks to keep track of your citations. 

5. Review the Literature (This will probably be the most time consuming part)

• What was the research question of the study you are reviewing?  What were the authors trying to discover? 
• Was the research funded by a company or source that could influence the findings? (Such as Colgate® sponsoring a toothpaste study?)
• What were the research methodologies? Analyze the paper's literature review, the samples and variables used, the results and conclusions. Does the research seem to be complete? Could it have been conducted more soundly? What questions does it raise? 
• If there are conflicting studies, why do you think that is? 
• How are the authors of the paper viewed in the field? Has this study been cited by other publications? 

Literature Review Examples

Remember, a lit review provides an intelligent overview of the topic. There may or may not be a method for how studies are collected or interpreted. Lit reviews aren't always labeled specifically as "literature reviews," they may often be embedded with other sections such as an introduction or background.

Module 4: Strategic Reading

Organize your Readings with a Literature Review Matrix

The next step after reading and evaluating your sources is to organize them in a way that will help you start the writing process.

Review Matrix

One way to organize your literature is with a review matrix. The review matrix is a chart that sorts and categorizes the different arguments presented per topic or issue. Using a matrix enables you to quickly compare and contrast your sources in order to determine the scope of research across time. This will allow you  to spot similarities and differences between sources. It is particularly useful in the synthesis and analysis stages of a review (See Module 1 Conducting a Literature Review with the SALSA Framework ).

Example of a Review Matrix

My research question:

How can we use machine learning to analyze social media data related to HIV?

Writing a Literature Review Modified from The WI+RE Team,  UCLA. Creative Commons CC-BY-NA-SA

Create a Review Matrix

Start with a charting tool you are most familiar with (for example MS Word, MS Excel, Google Sheets, Numbers etc).

• Organize your sources from oldest to most recent. This way you can see how the research on your topic has changed over time.
• First Column: citation (i.e., author, title, source, publication year)
• Second Column: purpose or summary (1-2 sentences)
• methodology
• intervention

Using a spreadsheet or table to organize the key elements (e.g. subjects, methodologies, results) of articles/books you plan to use in your literature review can be helpful. This is called a review matrix.

When you create a review matrix, the first few columns should include (1) the authors, title, journal, (2) publication year, and (3) purpose of the paper. The remaining columns should identify important aspects of each study such as methodology and findings.

What is a literature matrix?

As defined by Judith Garrard in her handbook entitled  Health Sciences Literature Reviews Made Easy: The Matrix Method , a “Review of the literature consists of reading, analyzing, and writing a synthesis of scholarly materials about a specific topic. When reviewing scientific literature, the focus is on the hypotheses, the scientific methods, the strengths and weaknesses of the study, the results, and the authors’ interpretations and conclusions.” When reading materials for a literature review, you should critically evaluate the study’s major aims and results. 

The purpose of completing a literature matrix is to help you identify important aspects of the study. Literature matrixes contain a variety of headings, but frequent headings include: author surname and date, theoretical/ conceptual framework, research question(s)/ hypothesis, methodology, analysis & results, conclusions, implications for future research, and implications for practice. You can add additional columns as needed, and you might consider adding a “notes column” to proactively have important quotations and your thoughts already collected.  As you read journal articles, have your literature matrix ready. It is best to fill in the matrix directly after reading a work, rather than returning to the matrix later.  

Literature Matrix Files

You should use a literature matrix that best helps you to organize your reading and research. Excel workbooks can help to organize your research. Sample basic and complex literature matrixes are provided below: 

• Literature Matrix Basic BLANK
• Literature Matrix Basic SAMPLE
• Literature Matrix Complex BLANK

Synthesize vs. Summarize

When writing your literature review, you will not simply summarize the materials that you found related to your topic. A summary is a recap of the information provided in research articles. Summaries provide basic information about the study, but the details provided in a summary are not enumerative or systematic. 

Synthesizing goes beyond summarizing to explore specific aspects of the research study. When synthesizing the literature, rely on your completed literature matrix to inform your writing. Do you see any tends across publications? Was one type of methodology used repeatedly, why or why not? Did separate teams of researchers come to the same conclusion, differing conclusions, or is the literature inconclusive? Synthesizing requires that you look at the current state of the research overall. 

When preparing to write a synthesis, you will read the literature available, tease apart individual findings and supporting evidence across different articles, and then reorganize this information in a way that presents your understanding of the current state of research in this field.

Synthesis Matrix

A synthesis matrix helps you record the main points of each source and document how sources relate to each other.

After summarizing and evaluating your sources, arrange them in a matrix or use a citation manager to help you see how they relate to each other and apply to each of your themes or variables.  

By arranging your sources by theme or variable, you can see how your sources relate to each other, and can start thinking about how you weave them together to create a narrative.

Literature Review Outline

Ai generator.

Literature Review. We all been there, especially those who are currently in high school or college. We get to review different types of literary pieces ranging from short stories , poem , and novels just to name a few. It can be confusing when you have a lot of ideas but you have no idea how to formulate them into one clean thought. It can also be quite frustrating if you have to start from the beginning or back to square one if you forgot a single part of the whole, but don’t worry, here are some literature review outline examples you can download to help you with your problems. Let’s check them out.

What is a Literature Review Outline?

A literature review outline is a structured framework that organizes and summarizes existing research on a specific topic. It helps identify key themes, gaps, and methodologies in the literature. The outline typically includes sections such as introduction, major themes, sub-themes, methodologies, and conclusions, facilitating a clear and comprehensive review of the literature.

Literature Review Format

A literature review is a comprehensive summary of previous research on a topic. It includes a systematic examination of scholarly article , book , and other sources relevant to the research area. Here’s a guide to structuring a literature review effectively:

Introduction

• Explain the purpose of the literature review.
• Define the scope of the review – what is included and what is excluded.
• State the research question or objective .
• Provide context or background information necessary to understand the literature review.
• Highlight the significance of the topic.
• Organize the literature review by themes, trends, or methodological approaches rather than by individual sources.
• Use headings and subheadings to categorize different themes or topics.
• For each theme or section, summarize the key findings of the relevant literature.
• Highlight major theories, methodologies, and conclusions.
• Note any significant debates or controversies.
• Critically evaluate the sources.
• Discuss the strengths and weaknesses of the existing research.
• Identify gaps or inconsistencies in the literature.
• Compare and contrast different sources.
• Synthesize the information to provide a coherent narrative.
• Show how the different studies are related to one another.
• Summarize the main findings from the literature review.
• Highlight the most important insights and their implications.
• Identify any gaps in the existing research that require further investigation.
• Suggest areas for future research.
• Discuss the overall significance of the literature review.
• Explain how it contributes to the field of study and the specific research question.
• List all the sources cited in the literature review.
• Follow the appropriate citation style (APA, MLA , Chicago, etc.) as required by your academic institution.

Research Literature Review Outline Example

I. Introduction Background Information: Provide context and background on the research topic. Explain the importance of the topic in the current research landscape. Purpose of the Review: State the main objectives of the literature review. Clarify the research questions or hypotheses guiding the review. Scope of the Review: Define the scope, including time frame, types of studies, and key themes. Explain any limitations or boundaries set for the review. II. Search Strategy Databases and Sources: List the databases and other sources used to find relevant literature. Keywords and Search Terms: Detail the specific keywords and search terms employed. Inclusion and Exclusion Criteria: Describe the criteria for including or excluding studies. III. Theoretical Framework Relevant Theories: Introduce and explain the key theories and models related to the research topic. Application of Theories: Discuss how these theories provide a foundation for understanding the literature. IV. Review of Literature Thematic Organization: Organize the literature into themes or categories based on common findings or approaches. Example Structure: Theme 1: Impact of Rising Temperatures Summarize key studies and findings. Compare and contrast different research approaches. Theme 2: Changing Precipitation Patterns Highlight significant studies and their results. Discuss any conflicting findings or perspectives. Theme 3: Socioeconomic Factors Review literature focusing on socioeconomic impacts. Analyze how these factors interact with environmental changes. V. Critical Analysis Strengths and Weaknesses: Evaluate the strengths and limitations of the reviewed studies. Discuss the reliability and validity of the methodologies used. Methodological Critique: Assess the methodologies for potential biases and gaps. VI. Discussion and Synthesis Integration of Findings: Synthesize the findings from the literature into a cohesive narrative. Highlight common themes, trends, and gaps. Research Gaps: Identify areas where further research is needed. Suggest potential future research directions. VII. Conclusion Summary of Main Findings: Summarize the key insights and conclusions drawn from the literature review. Importance of the Topic: Reiterate the significance of the research topic. Implications for Future Research: Outline the implications of the findings for future research. VIII. References Citation List: Provide a complete list of all sources cited in the literature review. Follow a specific citation style (e.g., APA, MLA, Chicago). IX. Appendices (if applicable) Supplementary Material: Include tables, charts, or detailed methodological information that supports the review but is too extensive for the main text.

Thematic Literature Review Outline Example

I. Introduction Background Information: Provide context and background on the research topic. Explain the importance of the topic in the current research landscape. Purpose of the Review: State the main objectives of the literature review. Clarify the research questions or hypotheses guiding the review. Scope of the Review: Define the scope, including time frame, types of studies, and key themes. Explain any limitations or boundaries set for the review. II. Search Strategy Databases and Sources: List the databases and other sources used to find relevant literature. Keywords and Search Terms: Detail the specific keywords and search terms employed. Inclusion and Exclusion Criteria: Describe the criteria for including or excluding studies. III. Thematic Review of Literature Theme 1: Impact of Rising Temperatures Summary of Key Studies: Summarize the findings of major studies related to rising temperatures. Example: “Smith et al. (2020) found that increasing temperatures have led to a 5% decline in crop yields globally.” Comparison of Research Approaches: Compare different methodologies and approaches used in the studies. Example: “While Jones (2018) used a longitudinal study, Brown (2019) employed a cross-sectional analysis.” Theme 2: Changing Precipitation Patterns Summary of Key Studies: Highlight significant studies and their results. Example: “Lee and Wang (2021) reported that altered precipitation patterns have increased the frequency of droughts.” Discussion of Conflicting Findings: Discuss any contradictory findings or differing perspectives. Example: “Contrary to Lee and Wang, Garcia (2020) found minimal impact of precipitation changes on crop health.” Theme 3: Socioeconomic Factors Summary of Key Studies: Review literature focusing on the socioeconomic impacts of climate change. Example: “Davis (2017) highlighted the disproportionate effects on small-scale farmers.” Analysis of Interactions: Analyze how socioeconomic factors interact with environmental changes. Example: “Economic instability exacerbates the vulnerability to climate impacts (Green, 2018).” IV. Critical Analysis Strengths and Weaknesses: Evaluate the strengths and limitations of the reviewed studies. Example: “Many studies provide robust data but often lack consideration of regional variability.” Methodological Critique: Assess the methodologies for potential biases and gaps.

Types of Literature Review

A literature review is an essential part of academic research, providing a comprehensive summary of previous studies on a particular topic. There are various types of literature reviews, each serving a different purpose and following a unique structure. Here, we explore the main types:

1. Narrative Review

A narrative review, also known as a traditional or descriptive review, provides a comprehensive synthesis of the existing literature on a specific topic. It focuses on summarizing and interpreting the findings rather than conducting a systematic analysis.

2. Systematic Review

A systematic review follows a rigorous and predefined methodology to collect, analyze, and synthesize all relevant studies on a particular research question. It aims to minimize bias and provide reliable findings.

3. Meta-Analysis

A meta-analysis is a subset of systematic reviews that statistically combines the results of multiple studies to arrive at a single conclusion. It provides a higher level of evidence by increasing the sample size and improving the precision of the results.

4. Scoping Review

A scoping review aims to map the existing literature on a broad topic, identify key concepts, theories, and sources, and clarify research gaps. It is often used to determine the scope of future research.

5. Critical Review

A critical review evaluates the quality and validity of the existing literature, often questioning the methodology and findings. It provides a critical assessment and aims to present a deeper understanding of the topic.

6. Theoretical Review

A theoretical review focuses on analyzing and synthesizing theories related to a specific topic. It aims to understand how theories have evolved over time and how they can be applied to current research.

7. Integrative Review

An integrative review synthesizes research on a topic in a more holistic manner, combining perspectives from both qualitative and quantitative studies. It aims to generate new frameworks and perspectives.

8. Annotated Bibliography

An annotated bibliography provides a summary and evaluation of each source in a list of references. It includes a brief description of the content, relevance, and quality of each source.

9. Rapid Review

A rapid review streamlines the systematic review process to provide evidence in a timely manner. It is often used in healthcare and policy-making to inform decisions quickly.

10. Umbrella Review

An umbrella review, or overview of reviews, synthesizes the findings of multiple systematic reviews on a particular topic. It provides a high-level summary and identifies broader patterns and trends.

Purpose of a Literature Review

A literature review is a critical component of academic research, serving multiple important purposes. It provides a comprehensive overview of existing knowledge on a topic, helps identify research gaps, and sets the context for new research. Here are the key purposes of a literature review:

1. Summarizing Existing Research

A literature review summarizes and synthesizes the findings of previous studies related to a specific topic. This helps researchers understand what is already known and what remains to be explored.

2. Identifying Research Gaps

By reviewing existing literature, researchers can identify gaps or inconsistencies in the current knowledge. This allows them to pinpoint areas where further investigation is needed and justify the need for their research.

3. Providing Context and Background

A literature review sets the context for new research by providing background information. It helps readers understand the broader landscape of the topic and how the current study fits into it.

4. Establishing the Theoretical Framework

Literature reviews often involve discussing various theories and models relevant to the topic. This helps establish a theoretical framework for the research, guiding the study’s design and methodology.

5. Demonstrating Researcher Knowledge

Conducting a thorough literature review demonstrates that the researcher is knowledgeable about the field. It shows that they are aware of the key studies, debates, and trends in their area of research.

6. Justifying Research Questions and Methodology

A literature review helps justify the research questions and methodology of a study. By showing how previous studies were conducted and what their limitations were, researchers can argue for their chosen approach.

7. Avoiding Duplication

Reviewing existing literature ensures that researchers do not duplicate previous studies unnecessarily. It helps them build on existing work rather than repeating it.

8. Highlighting Key Findings and Trends

A literature review highlights significant findings and trends in the research area. This helps researchers understand the development of the field and identify influential studies and seminal works.

9. Informing Practice and Policy

In applied fields, literature reviews can inform practice and policy by summarizing evidence on what works and what doesn’t. This helps practitioners and policymakers make evidence-based decisions.

10. Facilitating a Comprehensive Understanding

Overall, a literature review facilitates a comprehensive understanding of the topic. It integrates various perspectives, findings, and approaches, providing a well-rounded view of the research area.

Components of a Literature Review

A well-structured literature review is essential for providing a clear and comprehensive overview of existing research on a particular topic. The following components are typically included in a literature review:

1. Introduction

The introduction sets the stage for the literature review. It provides background information on the topic, explains the review’s purpose, and outlines its scope.

Example: “Over the past decade, research on climate change’s impact on agriculture has proliferated. This literature review aims to synthesize these studies, focusing on the effects of rising temperatures and changing precipitation patterns on crop yields.”

2. Search Strategy

The search strategy describes how the literature was identified. This includes the databases and search engines used, search terms and keywords, and any inclusion or exclusion criteria.

Example: “The literature search was conducted using databases such as PubMed, Google Scholar, and JSTOR. Keywords included ‘climate change,’ ‘agriculture,’ ‘crop yields,’ and ‘precipitation patterns.’ Studies published between 2000 and 2023 were included.”

3. Theoretical Framework

The theoretical framework presents the theories and models relevant to the research topic. This section provides a foundation for understanding the studies reviewed.

Example: “This review utilizes the Sustainable Livelihoods Framework to analyze the impact of climate change on agricultural communities, focusing on how environmental changes affect economic stability and food security.”

4. Review of Literature

The core of the literature review, this section summarizes and synthesizes the findings of the selected studies. It is often organized thematically, chronologically, or methodologically.

Example: “Studies from the early 2000s focused on temperature changes, while recent research has shifted to examining precipitation patterns. Common findings include a general decline in crop yields, with significant regional variations.”

5. Critical Analysis

A critical analysis evaluates the strengths and weaknesses of the existing research. This involves assessing the methodology, data, and conclusions of the studies reviewed.

Example: “Many studies used longitudinal data to track changes over time, but few incorporated socioeconomic factors. Additionally, the reliance on regional data limits the generalizability of some findings.”

6. Discussion and Synthesis

The discussion and synthesis section integrates the findings from the literature review, highlighting common themes, trends, and gaps. It connects the reviewed studies to the current research question.

Example: “The literature consistently shows that rising temperatures negatively affect crop yields. However, there is a gap in understanding the role of adaptive farming practices, suggesting a need for further research in this area.”

7. Conclusion

The conclusion summarizes the main findings of the literature review. It reiterates the importance of the research topic and outlines the implications for future research.

Example: “In summary, climate change poses a significant threat to agricultural productivity. Future research should focus on adaptive strategies to mitigate these effects and ensure food security.”

8. References

The references section lists all the sources cited in the literature review. It should follow a specific citation style, such as APA, MLA, or Chicago.

• Smith, J. (2021). Climate Change and Crop Yields . Journal of Environmental Science, 12(3), 45-60.
• Brown, A., & Jones, B. (2019). Precipitation Patterns and Agriculture . Climate Research, 8(2), 34-48.

9. Appendices (if applicable)

Appendices may include supplementary material that is relevant to the literature review but would disrupt the flow of the main text. This could include tables, charts, or detailed methodological information.

Example: “Appendix A includes a table of regional crop yield changes from 2000 to 2020. Appendix B provides a detailed description of the data collection methods used in the reviewed studies.”
