An APA abstract is a brief, comprehensive summary of the contents of an article, research paper, dissertation, or report.

It is written in accordance with the guidelines of the American Psychological Association (APA), which is a widely used format in social and behavioral sciences. 

An APA abstract summarizes, usually in one paragraph of between 150–250 words, the major aspects of a research paper or dissertation in a prescribed sequence that includes:

• The rationale: the overall purpose of the study, providing a clear context for the research undertaken.
• Information regarding the method and participants: including materials/instruments, design, procedure, and data analysis.
• Main findings or trends: effectively highlighting the key outcomes of the hypotheses.
• Interpretations and conclusion(s): solidify the implications of the research.
• Keywords related to the study: assist the paper’s discoverability in academic databases.

The abstract should stand alone, be “self-contained,” and make sense to the reader in isolation from the main article.

The purpose of the abstract is to give the reader a quick overview of the essential information before reading the entire article. The abstract is placed on its own page, directly after the title page and before the main body of the paper.

Although the abstract will appear as the very first part of your paper, it’s good practice to write your abstract after you’ve drafted your full paper, so that you know what you’re summarizing.

Note : This page reflects the latest version of the APA Publication Manual (i.e., APA 7), released in October 2019.

Structure of the Abstract

[NOTE: DO NOT separate the components of the abstract – it should be written as a single paragraph. This section is separated to illustrate the abstract’s structure.]

1) The Rationale

One or two sentences describing the overall purpose of the study and the research problem(s) you investigated. You are basically justifying why this study was conducted.

• What is the importance of the research?
• Why would a reader be interested in the larger work?
• For example, are you filling a gap in previous research or applying new methods to take a fresh look at existing ideas or data?
• Women who are diagnosed with breast cancer can experience an array of psychosocial difficulties; however, social support, particularly from a spouse, has been shown to have a protective function during this time. This study examined the ways in which a woman’s daily mood, pain, and fatigue, and her spouse’s marital satisfaction predict the woman’s report of partner support in the context of breast cancer.
• The current nursing shortage, high hospital nurse job dissatisfaction, and reports of uneven quality of hospital care are not uniquely American phenomena.
• Students with special educational needs and disabilities (SEND) are more likely to exhibit behavioral difficulties than their typically developing peers. The aim of this study was to identify specific risk factors that influence variability in behavior difficulties among individuals with SEND.

2) The Method

Information regarding the participants (number, and population). One or two sentences outlining the method, explaining what was done and how. The method is described in the present tense.

• Pretest data from a larger intervention study and multilevel modeling were used to examine the effects of women’s daily mood, pain, and fatigue and average levels of mood, pain, and fatigue on women’s report of social support received from her partner, as well as how the effects of mood interacted with partners’ marital satisfaction.
• This paper presents reports from 43,000 nurses from more than 700 hospitals in the United States, Canada, England, Scotland, and Germany in 1998–1999.
• The study sample comprised 4,228 students with SEND, aged 5–15, drawn from 305 primary and secondary schools across England. Explanatory variables were measured at the individual and school levels at baseline, along with a teacher-reported measure of behavior difficulties (assessed at baseline and the 18-month follow-up).

3) The Results

One or two sentences indicating the main findings or trends found as a result of your analysis. The results are described in the present or past tense.

• Results show that on days in which women reported higher levels of negative or positive mood, as well as on days they reported more pain and fatigue, they reported receiving more support. Women who, on average, reported higher levels of positive mood tended to report receiving more support than those who, on average, reported lower positive mood. However, average levels of negative mood were not associated with support. Higher average levels of fatigue but not pain were associated with higher support. Finally, women whose husbands reported higher levels of marital satisfaction reported receiving more partner support, but husbands’ marital satisfaction did not moderate the effect of women’s mood on support.
• Nurses in countries with distinctly different healthcare systems report similar shortcomings in their work environments and the quality of hospital care. While the competence of and relation between nurses and physicians appear satisfactory, core problems in work design and workforce management threaten the provision of care.
• Hierarchical linear modeling of data revealed that differences between schools accounted for between 13% (secondary) and 15.4% (primary) of the total variance in the development of students’ behavior difficulties, with the remainder attributable to individual differences. Statistically significant risk markers for these problems across both phases of education were being male, eligibility for free school meals, being identified as a bully, and lower academic achievement. Additional risk markers specific to each phase of education at the individual and school levels are also acknowledged.

4) The Conclusion / Implications

A brief summary of your conclusions and implications of the results, described in the present tense. Explain the results and why the study is important to the reader.

• For example, what changes should be implemented as a result of the findings of the work?
• How does this work add to the body of knowledge on the topic?

Implications of these findings are discussed relative to assisting couples during this difficult time in their lives.

• Resolving these issues, which are amenable to managerial intervention, is essential to preserving patient safety and care of consistently high quality.
• Behavior difficulties are affected by risks across multiple ecological levels. Addressing any one of these potential influences is therefore likely to contribute to the reduction in the problems displayed.

The above examples of abstracts are from the following papers:

Aiken, L. H., Clarke, S. P., Sloane, D. M., Sochalski, J. A., Busse, R., Clarke, H., … & Shamian, J. (2001). Nurses’ reports on hospital care in five countries . Health affairs, 20(3) , 43-53.

Boeding, S. E., Pukay-Martin, N. D., Baucom, D. H., Porter, L. S., Kirby, J. S., Gremore, T. M., & Keefe, F. J. (2014). Couples and breast cancer: Women’s mood and partners’ marital satisfaction predicting support perception . Journal of Family Psychology, 28(5) , 675.

Oldfield, J., Humphrey, N., & Hebron, J. (2017). Risk factors in the development of behavior difficulties among students with special educational needs and disabilities: A multilevel analysis . British journal of educational psychology, 87(2) , 146-169.

5) Keywords

APA style suggests including a list of keywords at the end of the abstract. This is particularly common in academic articles and helps other researchers find your work in databases.

Keywords in an abstract should be selected to help other researchers find your work when searching an online database. These keywords should effectively represent the main topics of your study. Here are some tips for choosing keywords:

Core Concepts: Identify the most important ideas or concepts in your paper. These often include your main research topic, the methods you’ve used, or the theories you’re discussing.

Specificity: Your keywords should be specific to your research. For example, suppose your paper is about the effects of climate change on bird migration patterns in a specific region. In that case, your keywords might include “climate change,” “bird migration,” and the region’s name.

Consistency with Paper: Make sure your keywords are consistent with the terms you’ve used in your paper. For example, if you use the term “adolescent” rather than “teen” in your paper, choose “adolescent” as your keyword, not “teen.”

Jargon and Acronyms: Avoid using too much-specialized jargon or acronyms in your keywords, as these might not be understood or used by all researchers in your field.

Synonyms: Consider including synonyms of your keywords to capture as many relevant searches as possible. For example, if your paper discusses “post-traumatic stress disorder,” you might include “PTSD” as a keyword.

Remember, keywords are a tool for others to find your work, so think about what terms other researchers might use when searching for papers on your topic.

The Abstract SHOULD NOT contain:

Lengthy background or contextual information: The abstract should focus on your research and findings, not general topic background.

Undefined jargon, abbreviations,  or acronyms: The abstract should be accessible to a wide audience, so avoid highly specialized terms without defining them.

Citations: Abstracts typically do not include citations, as they summarize original research.

Incomplete sentences or bulleted lists: The abstract should be a single, coherent paragraph written in complete sentences.

New information not covered in the paper: The abstract should only summarize the paper’s content.

Subjective comments or value judgments: Stick to objective descriptions of your research.

Excessive details on methods or procedures: Keep descriptions of methods brief and focused on main steps.

Speculative or inconclusive statements: The abstract should state the research’s clear findings, not hypotheses or possible interpretations.

• Any illustration, figure, table, or references to them . All visual aids, data, or extensive details should be included in the main body of your paper, not in the abstract. 
• Elliptical or incomplete sentences should be avoided in an abstract . The use of ellipses (…), which could indicate incomplete thoughts or omitted text, is not appropriate in an abstract.

APA Style for Abstracts

An APA abstract must be formatted as follows:

Include the running head aligned to the left at the top of the page (professional papers only) and page number. Note, student papers do not require a running head. On the first line, center the heading “Abstract” and bold (do not underlined or italicize). Do not indent the single abstract paragraph (which begins one line below the section title). Double-space the text. Use Times New Roman font in 12 pt. Set one-inch (or 2.54 cm) margins. If you include a “keywords” section at the end of the abstract, indent the first line and italicize the word “Keywords” while leaving the keywords themselves without any formatting.

How long should an APA abstract be?

An APA abstract should typically be between 150 to 250 words long. However, the exact length may vary depending on specific publication or assignment guidelines. It is crucial that it succinctly summarizes the essential elements of the work, including purpose, methods, findings, and conclusions.

Where does the abstract go in an APA paper?

In an APA formatted paper, the abstract is placed on its own page, directly after the title page and before the main body of the paper. It’s typically the second page of the document. It starts with the word “Abstract” (centered and not in bold) at the top of the page, followed by the text of the abstract itself.

What are the 4 C’s of abstract writing?

The 4 C’s of abstract writing are an approach to help you create a well-structured and informative abstract. They are:

Conciseness: An abstract should briefly summarize the key points of your study. Stick to the word limit (typically between 150-250 words for an APA abstract) and avoid unnecessary details.

Clarity: Your abstract should be easy to understand. Avoid jargon and complex sentences. Clearly explain the purpose, methods, results, and conclusions of your study.

Completeness: Even though it’s brief, the abstract should provide a complete overview of your study, including the purpose, methods, key findings, and your interpretation of the results.

Cohesion: The abstract should flow logically from one point to the next, maintaining a coherent narrative about your study. It’s not just a list of disjointed elements; it’s a brief story of your research from start to finish.

What is the abstract of a psychology paper?

An abstract in a psychology paper serves as a snapshot of the paper, allowing readers to quickly understand the purpose, methodology, results, and implications of the research without reading the entire paper. It is generally between 150-250 words long.

How to write an APA abstract

An APA abstract is a short summary designed to help a reader decide if they are going to read the entire paper. An effective abstract will communicate your hypothesis, method, and results while also creating credibility for yourself as the author. An abstract will also make it easier for new readers to find your work.

In this guide, you will learn how to format an APA abstract. It begins with an overview of the key aspects included with an abstract and ends with a set of real APA abstract examples that you can look at.

The information in this guide comes straight from the source: The Publication Manual of the American Psychological Association, 7 th edition. Most of the relevant information comes from Section 2.9.

Here’s a run-through of everything this page includes:

What is an APA abstract page?

How to format an apa abstract, paragraph format vs. structured format, adding a keywords section after your apa abstract, about apa formatting and the apa style guide.

While the abstract page plays an important role in getting the reader interested, it is not a sales pitch. It’s about reporting, not commenting. That means that it should accurately reflect each key aspect of your paper.  In other words, it is a concise, comprehensive summary of your paper.

This is where you describe the problem you were exploring, the methods you used to explore it, and the results or conclusions of your exploration. In some cases, you might also be required to state the significance of your conclusions.

Here are some of the key aspects of an APA abstract that might be requested by the publication:

• Basic problem : Why did this work need to be done?
• Clearly-stated hypotheses: What was your hypothesis?
• Methods of investigation: How did you do your research? How did you design your experiment or argument? For scientific papers, include basic sample information.
• Results: What was the result of your study?
• Implications: What is the significance of your findings?

Remember, the specific sections or labels in your abstract might vary based on who you are submitting to.

Qualities of a good abstract

In addition to the formatting requirements, the Publication Manual also provides some guidance on what other qualities make for a good abstract.

Here are the qualities of a good abstract as defined by APA. You can find more information on how to formulate a great abstract in chapter 3.

• Accurate: The most important thing is that your abstract accurately reflects the contents and purpose of your paper. The general rule of thumb for accuracy is, if it doesn’t appear in your paper, it should not appear in the abstract.
• Non-evaluative: The APA instructs us to “Report rather than evaluate” (p.73). It is inappropriate to add any opinions or comments to the abstract.
• Coherent and readable: Your abstract needs to be as clear as possible. Use concise, deliberate language. It helps to use verbs instead of nouns when possible (e.g., “investigated” rather than “an investigation of”).
• Concise: Make sure every sentence is as informative as possible. There should be no “extra” words in an abstract; it’s all about getting the point across as efficiently as possible. Because abstracts are often used for academic search engines, it is good practice to use specific terms that you think people would use to find your paper.

In large part, the abstract page is formatted just like any APA paper. That means that it should be 12pt font and double-spaced the whole way through.

A properly formatted abstract will also be:

• No more than 250 words in length.
• Placed on its own page, immediately following the APA title page .
• Labeled with a bold, center-justified “Abstract” at the top

It is important to note that some publications will have their own instructions on how to format the abstract. In addition, some publications require a statement of significance in addition to the abstract.

If you are submitting your paper to a journal, be sure to check the publication’s author instructions.

The abstract page of an APA paper can be presented in two ways. As the author, you have the option of presenting your abstract in either paragraph format or structured format .

Paragraph format is more common with student papers. This is a single paragraph with no indentation on the first line. The objective, method, results, and conclusions are presented one after another in a simple, narrative manner.

Structured format is similar in formatting with one key difference. This format calls for the insertion of specific labels to identify the different parts of the abstract. In other words, “Objective,” “Method,” “Results,” and “Conclusions” are presented as labels before their corresponding sentences in the abstract.

It’s important to remember that some publications have different labeling requirements. If you’re submitting your paper to a journal, be sure to check the formatting standards.

APA abstract example: Paragraph format

Let’s move on to a specific example of a properly formatted APA abstract written in paragraph format.

The following abstract is from the paper “Movement, wildness, and animal aesthetics” by Tom Greaves. Note how the first line is not indented like a normal paragraph.

The key role that animals play in our aesthetic appreciation of the natural world has only gradually been highlighted in discussions in environmental aesthetics. In this article I make use of the phenomenological notion of ‘perceptual sense’ as developed by Merleau-Ponty to argue that open-ended expressive-responsive movement is the primary aesthetic ground for our appreciation of animals. It is through their movement that the array of qualities we admire in animals are manifest qua animal qualities. Against functionalist and formalist accounts, I defend and develop an account of expressive-responsive movement as the primary perceptual sense of animals. I go on to suggest that the primacy of movement in the aesthetic appreciation of animals is also the primary sense of animal ‘wildness’, and that a key part of the rewilding paradigm should be the development of such appreciation.

In the paragraph above, Greaves uses his first sentence to explain the basic problem, and the next two sentences to describe the method. The fourth sentence presents the results, and the fifth sentence wraps things up with a conclusion.

It’s only five sentences, and it tells the reader everything they need to know about the contents of the paper.

APA abstract example: Structured format

Next up is an example of a properly formatted APA abstract written in structured format. This example uses the same abstract as above, with the addition of identifying labels.

Structured abstracts are only necessary when specifically requested by the class, institution, or journal you are submitting to. For all APA journals, these labels are bold, italicized, and capitalized.

Objective. The key role that animals play in our aesthetic appreciation of the natural world has only gradually been highlighted in discussions in environmental aesthetics. Method. In this article I make use of the phenomenological notion of ‘perceptual sense’ as developed by Merleau-Ponty to argue that open-ended expressive-responsive movement is the primary aesthetic ground for our appreciation of animals. It is through their movement that the array of qualities we admire in animals are manifest qua animal qualities. Results. Against functionalist and formalist accounts, I defend and develop an account of expressive-responsive movement as the primary perceptual sense of animals. Conclusions. I go on to suggest that the primacy of movement in the aesthetic appreciation of animals is also the primary sense of animal ‘wildness’, and that a key part of the rewilding paradigm should be the development of such appreciation.

A paper’s keywords section is intended to help people find your work. These are the acronyms, phrases, or words that describe the most important elements of your paper. Any papers submitted to an APA journal should include three to five keywords.

The keywords section is generally only required for professional papers. However, some professors and universities specifically request that it be included in student papers.

Formatting the keywords section

The keywords are presented on the same page as the abstract, one line below the end of the abstract paragraph. It begins with the label “Keywords:”, and it is italicized and indented 0.5in from the margin.

Next comes a list of the keywords separated by commas. The keywords should be lowercase, unless the keyword is a proper noun. There is no punctuation at the end of a keyword list.

APA abstract with keywords example

Take another look at the abstract example that was provided above. Here is what a set of keywords might look like for that paper, pulling between 3-5 specific terms from the abstract itself.

The keywords are placed one line below the abstract without any additional spaces.

Keywords: animals, animal aesthetics, wildness, rewilding

The information in this guide came from the Publication Manual of the American Psychological Association (7 th ed.). Chapter 2 of this book lays out the basic formatting elements for APA 7, including how to write an APA abstract.

You can also consult chapter 3.3 for more in-depth recommendations on how to formulate your abstract based on what type of paper you are writing.

How to Write an Abstract in APA Format

• 3-minute read
• 2nd November 2023

If you’re writing an in-depth research paper following APA guidelines, you most likely need to include an abstract . If you’re confused about where to start – don’t be. We’ve got you covered! In this post, we’ll walk you through the steps of formatting and writing an abstract in APA format.

What Is an Abstract?

An abstract is a brief summary of a larger academic text, such as a thesis, dissertation, or research paper, typically located at the very beginning of the paper before the introduction. Its main purpose is to give readers a clear and concise overview of your key points, objectives, results, and conclusion. Essentially, it lets the reader know the purpose and premise of your study and what to expect from your paper.

How to Write an Abstract Using APA Style

If you’re following APA guidelines, your abstract should include:

●  Your clearly stated hypothesis or hypotheses

●  The key takeaways of the literature review

●  Your research questions and/or objectives

●  The methods used in your study

●  The research design and sample/sample size

●  Your results and key findings

●  The significance of your study and the implications of your findings

Note that you should provide a short overview of these points and not an in-depth analysis (which will come later in your paper) – each should be around one to two sentences long. The total length will vary depending on a variety of factors, such as your university/journal specifications, topic, and the length of your paper, but APA guidelines recommend that abstracts shouldn’t exceed 250 words.

How to Format an Abstract in APA Format

How should you format your abstract if you’re using APA style? To start, the abstract should be located on the second page of your paper, after the title page. To format your abstract:

●  Set one-inch margins on all sides.

●  Label the section “Abstract” on the first line of the page, centered, and using bold font.

●  Use a clear, readable, widely available font, such as Times New Roman (12 pt.) or Calibri (11 pt.).

●  Begin writing the text one line below the “Abstract” label.

●  Do not indent and write text as a single paragraph.

APA guidelines state that three to five keywords can be included at the end of your abstract, which makes your paper searchable in a database. Be sure to choose brief, relevant keywords or phrases that reflect the most important aspects of your study. Keywords should be written one line below the text of the abstract immediately following the label “Keywords” in italics . Keywords can be listed in any order and should be separated using commas.

For example, for a journal article titled Biodiversity and Environmental Resilience: Strategies for Sustainability , the keywords section could look like this:

Note that keywords should be written in lowercase (unless they’re proper nouns) and no end punctuation is necessary after the final keyword.

How to craft an APA abstract

Last updated

16 December 2023

Reviewed by

An APA abstract is a brief but thorough summary of a scientific paper. It gives readers a clear overview of what the paper is about and what it intends to prove.

The purpose of an abstract is to allow researchers to quickly understand the paper's topic and purpose so they can decide whether it will be useful to them.

• What is the APA style?

APA style is a method of formatting and documentation used by the American Psychological Association. This style is used primarily for papers in the field of education and in the social sciences, including:

Anthropology

What is an abstract in APA format?

Writing an abstract in APA format requires you to conform to the writing rules for APA-style papers, including the following guidelines:

The abstract should be 150–250 words

It should be brief but concise, containing all the paper's main points

The abstract is a separate page that comes after the title page and before the paper's main content

• Key elements of an APA abstract 

While the rules for constructing an APA abstract are straightforward, the process can be challenging. You need to pack a great deal of relevant content into a short piece.

The essential elements of an APA abstract are:

Running header containing the title of the paper and page number

Section label, centered and in bold, containing the word "abstract"

The main content of the abstract, 150–250 words in length and double-spaced

A list of keywords, indented and introduced with the word "keywords" in italics

Essential points to cover in an APA abstract  

When you’re creating your APA abstract, consider the following questions.

What is the main topic the paper is addressing?

People searching for research on your topic will probably be browsing many papers and studies. The way your abstract is crafted will help to determine whether they feel your paper is worth reading.

Are your research methods quantitative or qualitative?

Quantitative research is focused on numbers and statistics, typically gathered from studies and polls where the questions are in yes/no or multiple-choice format.

Qualitative research is based on language and gathered using methods such as interviews and focus groups. It is more detailed and time-consuming to gather than quantitative research but can yield more complex and nuanced results.

Did you use primary or secondary sources?

Another key element is whether your research is based on primary or secondary sources. 

Primary research is data that you or your research team gathered. Secondary research is gathered from existing sources, such as databases or previously published studies.

Is your research descriptive or experimental?

Your research may be descriptive, experimental, or both.

With descriptive research , you’re describing or analyzing existing studies or theories on the topic. You may be using surveys, case studies, or observation to study the topic.

Experimental research studies variables using the scientific method. With an experiment, your objective is to establish a cause-and-effect relationship between two variables (or show the lack of one).

What conclusion did you reach?

Readers will want to know upfront what your paper is claiming or proving. Your APA abstract should give them a condensed version of your conclusions. Summarize your most significant findings.

It's customary to place your findings and conclusion in the final sentence of the abstract. This should be directly related to the main topic of the paper.

What is the relevance of your findings?

Show readers that your paper is a significant contribution to the field. While staying accurate and not overstating your case, boast a bit about why people need to read your paper.

Briefly describe the implications and importance of your findings. You can also point out any further research that is needed concerning this topic.

Did you choose the most appropriate keywords?

Including keywords is useful for indexing if your paper is eventually included in a database. Choose keywords that are relevant to the paper and as specific as possible.

For example, if your paper is about signs of learning disabilities in elementary-age children, your keyword list might include:

Learning disability symptoms

Elementary education

Language-based learning disabilities

Any other terms discussed in the paper

• How to format an APA abstract

Use standard APA formatting with double spacing, 12pt Times New Roman font, and one-inch margins.

Place a running head at the top left-hand side of the page. This is an abbreviated version of the paper's title. Use all capital letters for the running header. This is not usually required for academic papers but is essential if you are submitting the paper for publication. The page number “2” should follow the running header (Page 1 is the title page).

Just under the running head, in the center, place the word "abstract."

Place your list of keywords at the end. The list should be indented and, according to APA guidelines, contain three to five keywords.

• What are the 3 types of abstracts?

There are certain variations in different types of APA abstracts. Here are three of the most common ones.

Experimental or lab report abstracts

An abstract for an experimental or lab report needs to communicate the key purpose and findings of the experiment. Include the following:

Purpose and importance of the experiment

Hypothesis of the experiment

Methods used to test the hypothesis

Summary of the results of the experiment, including whether you proved or rejected the hypothesis

Literature review abstracts

A literature review is a survey of published work on a work of literature. It may be part of a thesis, dissertation, or research paper .

The abstract for a literature review should contain:

A description of your purpose for covering the research topic

Your thesis statement

A description of the sources used in the review

Your conclusions based on the findings

Psychology lab reports

Psychology lab reports are part of the experiment report category. Psychology experiments, however, may contain distinctive elements.

Describe the goal or purpose of the experiment

If the experiment includes human subjects, describe them. Mention the number of participants and what demographic they fit

Describe any tools, equipment, or apparatus you used for the experiment. For example, some experiments use electroencephalography (EEG) to measure brain waves. You may have also used tools such as questionnaires , case studies , or naturalistic observation. Describe the procedure and parameters of the experiment.

Summarize your conclusions

• What not to include in an APA abstract

As this section is 250 words maximum, it's important to know what should not be included.

Avoid the following in an APA abstract:

Jargon, acronyms, or abbreviations

Citations. These should appear in the body of the paper.

Lengthy or secondary information. Keep it brief and stick to the main points. Readers should want to read your paper for more detailed information.

Opinions or subjective comments

Anything not covered in the paper

• Guidelines for writing an APA abstract

While an abstract is the shortest section of your paper, it is nevertheless one of the most important parts. It determines whether or not someone decides that the paper is worth reading or not. What follows are some guidelines to keep in mind when creating your APA abstract. 

Focus on your main point. Don't try to fit in multiple conclusions. The idea is to give readers a clear idea of what your main point or conclusion is. On a similar note, be explicit about the implications and significance of your findings. This is what will motivate people to read your paper.

Write the abstract last. Ensure the abstract accurately conveys the content and conclusions of your paper. You may want to start with a rough draft of the abstract, which you can use as an outline to guide you when writing your paper. If you do this, make sure you edit and update the abstract after the full paper is complete.

Proofread your abstract. As the abstract is short and the first part of the paper people will read, it's especially important to make it clear and free of spelling, grammatical, or factual errors. Ask someone in your field to read through it.

Write the abstract for a general audience. While the paper may be aimed at academics, scientists, or specialists in your field, the abstract should be accessible to a broad audience. Minimize jargon and acronyms. This will make the paper easier to find by people looking for information on the topic.

Choose your keywords with care. The more relevant keywords you include, the more searchable your paper will be. Look up papers on comparable topics for guidance.

Follow any specific guidelines that apply to your paper. Requirements for the abstract may differ slightly depending on the topic or guidelines set by a particular instructor or publication.

APA style is commonly used in the fields of psychology, sociology, anthropology, economics, and education.

If you’re writing an abstract in APA style, there are certain conventions to follow. Your readers and people in your industry will expect you to adhere to particular elements of layout, content, and structure.

Follow our advice in this article, and you will be confident that your APA abstract complies with the expected standards and will encourage people to read your full paper.

How to Write an APA Abstract

Verywell / Nusha Ashjaee 

• Writing Your Abstract
• How to Use Keywords

An APA abstract is a concise but comprehensive summary of a scientific paper. It is typically a paragraph long, or about 150 to 250 words. The goal of the abstract is to provide the reader with a brief and accurate idea of what a paper is about.

The APA abstract should appear on a separate page immediately after the title page and before the main content of your paper. While professional papers that appear in scientific journals and other publications require an APA abstract, they may not be required for student papers. However, you should always check with your instructor for specific requirements.

What Is APA Format?

APA format is the official style of the American Psychological Association. It is used in writing for psychology and other social sciences. These style guidelines specify different aspects of a document's presentation and layout, including how pages are structured, how references are organized, and how sources are cited.

This article explains how to create an abstract in APA format for your psychology papers or other types of scientific writing. It covers the basic rules you should follow as well as specific guidelines for writing abstracts for experimental reports, literature reviews, and other articles.

What Is an Abstract in APA Format?

In addition to providing guidance for the general style and organization of a paper, APA format also stipulates using an abstract designed to briefly summarize the key details in a paper.

While it is sometimes overlooked or only an afterthought, an abstract is an integral part of any academic or professional paper. The abstract is a critical component of an APA-formatted paper. This brief overview summarizes what your paper contains. It should succinctly and accurately represent what your paper is about and what the reader can expect to find.

Following a few simple guidelines, you can create an abstract following the format. Done well, an abstract generates interest in your work and helps readers learn if the paper will interest them.

APA Format Abstract Basics

The abstract is the second page of a lab report or APA-format paper and should immediately follow the title page . Think of an abstract as a highly condensed summary of your entire paper.

The purpose of your abstract is to provide a brief yet thorough overview of your paper. It should function much like your title page—it should allow the person reading it to quickly determine what your paper is all about. Your abstract is the first thing that most people will read, and it is usually what informs their decision to read the rest of your paper.

The abstract is the single most important paragraph in your entire paper, according to the APA Publication Manual. A good abstract lets the reader know that your paper is worth reading.

According to the official guidelines of the American Psychological Association, an abstract should be brief but packed with information. Each sentence must be written with maximum impact in mind. To keep your abstract short, focus on including just four or five of the essential points, concepts, or findings.

An abstract must also be objective and accurate. The abstract's purpose is to report rather than provide commentary. It should accurately reflect what your paper is about. Only include information that is also included in the body of your paper.

Key Elements of an APA Abstract

Your abstract page should include:

• A running head , which is a shortened version of your title that appears in all caps at the top left of each page of your paper
• A section label , which should be the word "Abstract" centered and bolded at the top of the page
• A page number , which should be the second page of your paper (the title page should be page 1)
• A double-spaced paragraph of about 150 to 250 words
• An indented list of keywords related to your paper's content. Include the label "Keywords:" in italics and list three to five keywords that are separated by commas

How to Write an Abstract in APA Format

Before you write your abstract, you first need to write your paper in its entirety. In order to write a good abstract, you need to have a finished draft of your paper so you can summarize it accurately.

While the abstract will be at the beginning of your paper, it should be the last section you write.

Once you have completed the final draft of your psychology paper , use it as a guide for writing your abstract.

• Begin your abstract on a new page . Place your running head and page number 2 in the top right-hand corner. Center the word "Abstract" at the top of the page.
• Know your target word count . An abstract should be between 150 and 250 words. Exact word counts vary from journal to journal . If you are writing your paper for a psychology course, your professor may have specific word requirements, so be sure to ask. The abstract should be written as only one paragraph with no indentation.
• Structure the abstract in the same order as your paper . Begin with a brief summary of the introduction , and then continue on with a summary of the method , results , and discussion sections of your paper.
• Look at other abstracts in professional journals for examples of how to summarize your paper . Notice the main points that the authors chose to mention in the abstract. Use these examples as a guide when choosing the main ideas in your own paper.
• Write a rough draft of your abstract . Use the format required for your type of paper (see next sections). While you should aim for brevity, be careful not to make your summary too short. Try to write one to two sentences summarizing each section of your paper. Once you have a rough draft, you can edit for length and clarity.
• Ask a friend to read over the abstract . Sometimes, having someone look at your abstract with fresh eyes can provide perspective and help you spot possible typos and other errors.

The abstract is vital to your paper, so it should not be overlooked or treated as an afterthought. Spend time writing this section carefully to ensure maximum readability and clarity.

It is important to remember that while the abstract is the last thing you write, it is often the most read part of your paper.

Experimental Report Abstracts

The format of your abstract also depends on the type of paper you are writing. For example, an abstract summarizing an experimental paper will differ from that of a meta-analysis or case study . For an experimental report, your abstract should:

• Identify the problem . In many cases, you should begin by stating the question you sought to investigate and your hypothesis .
• Describe the participants in the study . State how many participants took part and how they were selected. For example: "In this study, 215 undergraduate student participants were randomly assigned to [the experimental condition] or [the control condition]."
• Describe the study method . For example, identify whether you used a within-subjects, between-subjects, or mixed design.
• Give the basic findings . This is essentially a brief preview of the results of your paper. 
• Provide any conclusions or implications of the study . What might your results indicate, and what directions does it point to for future research?

Literature Review Abstracts

If your paper is a meta-analysis or literature review, your abstract should:

• Describe the problem of interest . In other words, what is it that you set out to investigate in your analysis or review?
• Explain the criteria used to select the studies included in the paper . There may be many different studies devoted to your topic. Your analysis or review probably only looks at a portion of these studies. For what reason did you select these specific studies to include in your research?
• Identify the participants in the studies . Inform the reader about who the participants were in the studies. Were they college students? Older adults? How were they selected and assigned?
• Provide the main results . Again, this is essentially a quick peek at what readers will find when they read your results section. Don't try to include everything. Just provide a very brief summary of your main findings. 
• Describe any conclusions or implications . What might these results mean and what do they reveal about the body of research that exists on this particular topic?

Lab Reports and Articles

Psychology papers such as lab reports and APA format articles also often require an abstract. In these cases as well, the abstract should include all of the major elements of your paper, including an introduction, hypothesis, methods, results, and discussion.

Remember, although the abstract should be placed at the beginning of your paper (right after the title page), you will write the abstract last after you have completed a final draft of your paper.

To ensure that all of your APA formatting is correct, consider consulting a copy of the  Publication Manual of the American Psychological Association .

Keywords in an APA Abstract

After the paragraph containing the main elements of your abstract, you can also include keywords related to your paper. Such keywords are used when indexing your paper in databases and can help researchers and students locate your paper when searching for information about those topics.

Because keywords help people find your paper, it is essential to choose the right ones. The APA suggests including between three and five keywords.

You can identify keywords by thinking about what your paper is about. For example, if your paper focuses on how social media use is related to depression in teenagers, you might include the keywords: social media, mood, depression, adolescents, social networking sites 

A Word From Verywell

The abstract may be very brief, but it is so important that the official APA style manual identifies it as the most important paragraph in your entire paper. Careful attention to detail can ensure that your abstract does a good job representing the contents of your paper. If possible, take your paper to your school's writing lab for assistance.

APA abstract page: format and template

An abstract is a summary of the main contents of a paper. This part is the first glimpse of information a person gets before reading the whole paper. An abstract can influence the popularity of a paper, as a well-written one will attract readers and a poorly-written one will drive them away. In order to write a great abstract and captivate as many readers as possible, we gathered the abstract rules for both APA 6th and 7th edition.

APA abstract: quality check

First things first, you have to bear in mind the following points while writing an abstract.

• Be accurate: make sure that the abstract includes only the relevant information regarding the purpose and content of your paper.
• Report, do not evaluate: the abstract has the mere objective of sharing the content of your research. Do not discuss or comment.
• Make it readable: write as clear as possible. The use of verbs instead of nouns (e.g. “studied” instead of “a study of)” and the active rather than the passive voice (e.g. “we show”, instead of “it is shown”) is encouraged.
• Be concise: pack as much information as possible in each sentence. Start the abstract with the most relevant topics and do not repeat the main title.

APA abstract format

Moving on to the technical part, these are the rules to follow to write an abstract for submissions to APA journals. For non-APA journals make sure to check the respective guidelines.

• You should have between 150-250 words .
• An abstract has its own page , usually following the title page making it page 2.
• The preferred font is 12 -point Times New Roman .
• Use double line spacing .
• Set 1 inch margins .
• Include a running head at the top left corner of every page.
• The title of the section should be labeled as “ Abstract ” in bold, centered at the top of the page. The text should be placed right below the title.
• There are two ways of writing the text, as a paragraph or as a structured text . The first should be written as a single paragraph without indentation of the first line. A structured text is also a paragraph without indentation, but this one features labels within the text to classify different sections (e.g. Method, Objective, Results).
• Provide three to five keywords describing the content. Write them in italic one line below the abstract, indent it 0.5 in, followed by the keywords in lowercase capitalizing proper nouns, separated with commas. Keywords are listed in no specific order. If they run onto a second line, do not indent this one.

Frequently Asked Questions about APA abstract page

Yes. If you chose to use a 12-point Times New Roman in your paper, then the abstract should have the same font and size.

According to APA 7th guidelines, there are two ways of writing the text, as a paragraph or as a structured text . The first should be written as a single paragraph without indentation of the first line. A structured text is also a paragraph without indentation, but this one features labels within the text to classify different sections (e.g. Method, Objective, Results).

You can include three to five words, phrases or acronyms as keywords.

An abstract in APA style should address the following points:

• key aspects of the literature review
• problem under investigation or research question(s)
• clearly stated hypothesis or hypotheses
• methods used (including brief descriptions of the study design, sample, and sample size)
• study results
• implications (i.e., why this study is important, applications of the results or findings)

An APA abstract should have between 150-250 words.

• Abstracts & Keywords
• Authors & Publication Dates
• Titles & Sources
• In-line, Within-Text Citation ch.8
• Is this a "real" journal? evaluating journals
• Tables and Figures
• Librarian contact

Always follow the abstract guidelines by the journal you are wishing to publish in. That being said, these are some general requirements for writing abstracts:

• An abstract is a summary of the research or article.  Essentially the goal of the abstract is to give a one or two sentence summary from each section  of the article, which typically contains an introduction, methods or design, results, discussion or conclusion. There can be of course deviations from this, but this is typical
• abstracts are in paragraph form. However, some journals have specific formats, one example is below.
• The norm is for 200-250 words for the abstract. Be concise.

What are the keywords for? They are used for indexing and abstracting of your articles, i.e., they help people searching in databases to be able to find your article.

What should I use for keywords? Basically you want to use words that collectively describe your research. They should summarize what your article is about. Look at some publications in your research area and see how they write their keywords. Really think about what the keywords in that particular research are describing or trying to focus on. 

What is the format for keywords? Always follow the journal guidelines that you are publishing in. Most likely they will have specifics. Following APA 7th edition guidelines, the phrase Keywords is to be in italics with a colon, followed by the keywords or phrases separated by commas. After the last keyword, no punctuation is used.   

So if I were writing keywords for this research guide I might use:

Keywords: library research guides, LibGuides, APA 7th edition, citation styles

In this study, we questioned how high school dress codes outlined in official handbooks were written or presented in regard to the gender binary, either/or perspective. We critically analyzed how or if they allowed for flexibility in expression of gender and sexual identity and if they supported, encouraged, or affirmed a variety of expressions, in particular transgender and gender non-conforming expressions, throughout the text or images. The content analysis method was used to analyze 735 handbooks from the 2016 to 2017 school year. Three themes emerged from the data: (1) support of fluid gender expression, yet not overt support; (2) passive marginalization of gender non-conforming or transgender identities or expressions; and (3) active marginalization of gender non-conforming or transgender identities or expressions. The “LGBTQ+ Dress Code Analysis Tool” was developed for policy makers to use to analyze their dress codes.

Keywords : Dress code, gender, high school, LGBTQ+, queer, sexuality

A good abstract summarizes the key points of your paper without providing unnecessary detail. The APA style guide has a specific format for abstract pages, so you should be aware of this format if you are writing an APA paper. Moreover, there are other details to keep in mind concerning how to write an effective abstract. Here's what you should know.

Things You Should Know

• Write and finalize your paper before writing the abstract.
• Center the word "Abstract" at the top of the page, under the header.
• Write a 150-250 word paragraph stating the purpose, methods, scope, results, conclusions, and recommendations included in your paper.

Following the Basic Format

• A shortened version of your paper's title should be aligned to the top left of the page. The character count should not exceed 50 characters, including spaces and punctuation.
• Every letter in the page header should be capitalized.
• The page number should appear in the top right of the page. An APA abstract should be the second page of your paper, so the number "2" should appear in the corner.

• Some professors will also accept Arial font in 10-point or 12-point, but you should check with your professor before deciding to choose it.

• "Double-spaced" means that lines of texts are separated by a blank line.
• Aside from the abstract, the entire paper should also be double-spaced.

• The first letter of the word is capitalized, but the rest of the word is in lower-case.
• Do not bold, italicize, or underline the word, and do not use quotation marks. The word should stand alone and in normal font.

• Keep it short. A standard APA abstract is 150 to 250 words long and contained in a single paragraph.

• Indent as though starting a new paragraph.
• Type the word "Keywords" in italics. Capitalize the "K" and follow it with a colon.
• In normal, non-italicized font, follow the colon with three to four keywords describing the paper. These keywords should each appear in the text of the abstract. Separate them with commas.

Writing a Good Abstract

• To reflect the fact that it is a summary, your abstract should use present tense when referring to results and conclusions and past tense when referring to methods and measurements taken. Do not use future tense.
• Reread your essay before writing the abstract to refresh your memory. Pay close attention to the purpose, methods, scope, results, conclusions, and recommendations mentioned in your paper.
• Write a rough draft of your abstract without looking directly at your paper. This will help you to summarize without copying key sentences from your paper.

• An informational abstract states the purpose, methods, scope, results, conclusions, and recommendations included in your report. The abstract should highlight essential points in order to allow the reader to decide whether or not to read the rest of the report. Its total length should be about 10 percent or less of the length of the report.
• Descriptive abstracts include the purpose, methods, and scope defined in the report, but not the results, conclusions, or recommendations. These abstracts are less common to APA style and usually fall under 100 words. The purpose is the introduce the subject to the reader, essentially teasing the reader into reading the report in order to learn the results.

• For instance, ask yourself why you did the study, what you did, how you did it, what you found, and what those findings signify.
• If your paper is about a new method, ask yourself what the advantages of the new method are and how well it works.

• Even if the information is closely tied to information used in the paper, it does not belong in the abstract.
• Note that you can and should use different wording in your abstract. The information should be the same as the information in your paper, but the way that information is phrased should differ.

• Avoid phrases like, "This paper will look at..." Since the abstract is so short, you should cut straight to the facts and details of your paper instead of spending effort explaining their connection to your paper.
• Do not rephrase or repeat the title since the abstract is almost always read along with the title.
• The abstract should be complete on its own since it is often read without the rest of the paper.

• You can and should state your findings, but do not attempt to justify them. The paper itself should be used to justify your findings and provide additional support, not the abstract.

• You should also stick with active verbs more often than passive verbs.
• For instance, the strongest statement for an abstract would be, "research shows." Avoid using phrases like "I researched" or "it was researched."

• Also avoid trade names and symbols.

Sample Abstracts

Community Q&A

• If you are writing a short APA paper for a professor and the instructions do not specifically call for an abstract, ask the professor to verify that he or she actually wants one. While APA style officially promotes the use of abstracts for all papers, many professors will allow or even prefer that you skip the abstract if the assignment only calls for a 1- to 2-page paper.

About This Article

To write an abstract in APA format, start by writing your paper first. After your paper is done, go back and reread what you've written to identify your purpose, methods, scope, results, and conclusions. State these clearly in your abstract, starting with a broad declaration of your topic, like "This paper explores the role of gender on career ambitions" and then providing more specific information about what is covered in your paper. As you write, use present tense and avoid using first person pronouns like "I" or "me." To learn how to format your font and headings correctly in APA format, read on! Did this summary help you?

The Basic Format of an APA Abstract with Examples

The first thing you'll notice on an APA abstract is the running head, in all caps. Directly to the right of it, you'll see the page number, which should be "2".

This is because the running head and page number are required in all APA papers, and continued at the top right-hand side of the page in all capital letters, along with the page number denoting the second page of the paper, following the title page.

Basic format of an APA abstract

In the basic format of an APA abstract, the word "Abstract" is centered and without additional font changes. Then the abstract content begins beneath it—all in one paragraph with no indentation and one-inch margins on either side.

Here is an example of the basic format of an APA abstract:

Notice that the running title of the paper and the page number are at the header of the page. The abstract itself is beneath the title "Abstract", which is centered and without additional format at the center of the page. Additionally, the keywords are included at the bottom—this time with an indentation and the word "Keywords" italicized. Each keyword is separated by a comma.

The abstract, itself, should be correctly formatted. Specifically, it should be one paragraph that is NOT indented, and it should include the following information:

• An introduction to previous studies
• The main problems with the previous studies that are address in the new study.
• How the new study has been conducted.
• What the new study reveals that adds to previous studies.
• Conclusions of the new studies that add to the literature on the topic.
• Keywords related to the topic, indented, with the title of "Keywords" italicized and the keywords themselves separated by commas.

Below is an example of a correctly formatted and written APA abstract.

This shows you the formatting required for an APA abstract, as well as an example abstract written. Notice how the opening sentence summarizes what the paper explores. The second and third sentences state the problem in research that the paper aims to address. And the abstract closes with the final aims of the paper, along with the results of the study.

Keywords are then included at the bottom. Notice how they are indented and separated by commas.

Also notice the white space at the bottom of the page. This is what you should aim for when writing your abstract. An abstract that takes up an entire page is often an overwritten, wordy one—and one that goes beyond the recommended 150 to 250-word abstract.

How to write and format an APA Abstract (6th edition)

Published on November 6, 2020 by Courtney Gahan .

An APA abstract is a summary of your paper in 150–250 words. It describes the research problem , methods , results and conclusions of your research. For published papers, it also includes a list of keywords.

Write the abstract after you have finished your paper, and place it on a separate page after the title page .

The formatting of the abstract page is the same as the rest of an APA style paper : double-spaced, Times New Roman 12pt font, one-inch margins, and a running head at the top of the page.

An APA abstract must be formatted as follows:

• Include the running head aligned to the left at the top of the page
• On the first line, write the heading “Abstract” (centered and without any formatting)
• Do not indent any part of the text
• Double space the text
• Use Times New Roman font in 12 pt
• Set one-inch (or 2.54 cm) margins
• If you include a “keywords” section at the end of the abstract, indent the first line and italicize the word “Keywords” while leaving the keywords themselves without any formatting

Prevent plagiarism. Run a free check.

Simply answer the following questions and put them together, then voila! You have an abstract for your paper.

• What is the problem? Outline the objective , research questions and/or  hypotheses .
• What has been done? Explain your research methods .
• What did you discover? Summarize the key findings and conclusions .

APA format: Basic Guide for Researchers

The American Psychological Association (APA) is an official style format that is used by researchers and authors for academic and scientific writing. It is basically a standardized style guide used in psychology, education, and social science. It provides a framework for structuring research papers, presenting findings in a clear and concise manner and for accurately cite sources. The other commonly used style guides are the MLA and the Chicago style formats.  

How to write your research paper in APA format    

In the APA style, you need to adhere to specific formats and guidelines throughout the research paper. Some of these are explained below:  

The APA format allows different types of fonts. Some of the recommended ones include 12-point Times New Roman, 11-point Georgia, 11-point Calibri and 11-point Arial. The chosen font should be consistently used throughout the document. Figure images have to be in sans serif font with size between 8 and 14 points. Footnotes should be smaller than the text font and the line spacing will also be different.  

APA style provides for five levels of headings, each having its own format. Level 1 is the main heading, level 2 corresponds to the sub-heading of level 1, level 3 corresponds to the sub-heading of level 2 and so on. The headings should be double spaced and should not be numbered or lettered.  

Line spacing:

Generally, the APA format recommends double spacing throughout the text with few exceptions.  

A one inch margin is to be provided on each side of the paper. For dissertations and thesis, experts’ advice considering specific instructions provided by your institution.  

Paragraph alignment and indentation:

Text should be aligned to the left margin leaving the right margin uneven or “ragged”. The first line of each paragraph in the text should be indented 0.5 inches from the left margin.  

Under the APA format , there are also certain guidelines to be followed while preparing different sections of the research paper. These include –   

• Title page: All manuscripts must have a title page. The title should be concise, and must accurately reflect the contents of the paper. The author’s name and institutional affiliation should be centred, and positioned just below the title.  
• Abstract: A key part of academic manuscripts, an abstract must provide a brief summary of the research paper, including the purpose, methodology, results, and conclusions. It should be written within 250 words and should be the second page of your paper. The heading needs to be given as “Abstract” which is centred and bold. The text of the abstract should be written in a single paragraph, double spaced and must not be indented. Three to five keywords can be given one line below the abstract. These should not be italicized or bold but must be written in lower case. They should be separated by commas and there should not be any ending punctuation at the end of the keywords.  
• Introduction: The introduction is an essential part of scientific manuscripts and should be presented in an interesting and engaging manner. It should be able to convey clearly a critical overview of existing empirical knowledge and highlight knowledge gaps in the topic of study. Additionally, the aim of the research, a well formulated hypothesis, and a description of what you intend to address in the study must be clearly mentioned.  
• Methods: This is another critical part of an academic paper that requires researchers to describe the methods and procedures that were used during the study or experiment. Providing a detailed description contributes to ensuring the reproducibility and replicability of the study. The methods section should explain the research design that was adopted, details of the participants of the study, the equipment or materials used and the variables of the study.  
• Results: Here, researchers have to provide a brief summary of the results of their study. It is important that data is presented in a tabular format or in the form of graphs and figures to make it more interesting and to be easily understood by the reader. It is important to keep in mind that a clear narrative must accompany the statistics provided.  
• Discussion: Researchers must use the discussion section to provide their interpretation of the results of their research and explain its significance. Subsequently, it is in this section that they must present whether or not their results support their hypothesis.  
• References: Each and every source mentioned in a research paper must be referenced and accurately cited in this section.  

References and citations in APA format  

In the APA format, the author-date citation system is followed. Here, a brief in-text citation is provided in the text of your paper of a research paper. It can even appear in tables, figures, footnotes or appendix. Only the author and date of publication is provided here. The readers can refer to the corresponding entry in the reference list where the full citation is provided.   

While writing in-text citations, it is important to ensure that spelling of author names and publication dates are same in the in-text and reference list. The reference provides an alphabetical listing. Following are some examples of citations in APA format for different sources.  

• Books : The author surname with first and middle initials is written first. Only the title of the book is italicized. For eg.  
• Author Surname, A.B. (Publication Year). Title of the book . Publisher.  
• Journal article: Author surname, A.B. (Publication Year). Article Title: Subtitle. Journal title, Volume (issue), page range. URL or DOI.  
• Newspaper or magazine article : Surname. (Date of Publication). Title of the article. Title of the Newspaper or Magazine . URL.

Sporadic occurrence of ensitrelvir-resistant sars-cov-2, japan.

Cite This Article

Using the GISAID EpiCoV database, we identified 256 COVID-19 patients in Japan during March 31–December 31, 2023, who had mutations in the SARS-CoV-2 nonstructural protein 5 conferring ensitrelvir resistance. Ongoing genomic surveillance is required to monitor emergence of SARS-CoV-2 mutations that are resistant to anticoronaviral drugs.

Ensitrelvir fumaric acid (hereafter ensitrelvir) is a drug that inhibits the 3-chymotrypsin-like protease of SARS-CoV-2, also known as nonstructural protein 5 (NSP5), thereby inhibiting virus replication ( 1 – 3 ). Ensitrelvir was first approved for use in Japan on November 22, 2022. After drug approval, ensitrelvir was prescribed widely after March 2023 by many internal medicine clinics throughout Japan for COVID-19 treatment; indeed, 227,216 doses have been distributed in Japan since March 31, 2023 ( 4 ). However, in other countries, ensitrelvir prescriptions have been limited to clinical trials. To track emergence of SARS-CoV-2 mutations conferring resistance to ensitrelvir, we searched the GISAID EpiCoV database ( https://www.gisaid.org ), which contains virus genome sequences collected from COVID-19 patients worldwide.

Figure . Sporadic occurrence of ensitrelvir-resistant SARS-CoV-2 mutants during December 2022–December 2023 in Japan. Solid line indicates the average number of COVID-19 cases. Weekly numbers of SARS-CoV-2 sequences harboring g.10199A>U and g.10199A>C...

We counted the number of SARS-CoV-2 cases that had NSP5 amino acid substitutions conferring ensitrelvir resistance ( 5 – 8 ) from March 31, 2023, the date ensitrelvir was first prescribed by general internal medicine clinics, through December 31, 2023 ( Table ). Although the occurrence of some NSP5 amino acid substitutions showed a regional bias, most were not associated with ensitrelvir prescription. For example, of the 77 sequences harboring the M46I amino acid substitution in NSP5 observed in the United States, 66 were identified in specimens collected during the same period in May 2023, suggesting an association with a cluster that likely arose from a sporadic occurrence. However, the M49L amino acid substitution in NSP5, which confers ensitrelvir resistance without attenuating virus infection both in vitro and in vivo ( 5 ), was observed in 256/49,414 (0.55%) virus sequences from Japan. By comparison, the M49L substitution was observed in 277/845,796 (0.03%) virus sequences deposited globally in the GISAID database; therefore, 92.4% of the deposited M49L mutant sequences of NSP5 were from Japan. The M49L substitution is caused by transversion of adenine at position 10199 within the SARS-CoV-2 NSP5 coding sequence to either cytosine or uracil. Of the 277 sequences with the M49L amino acid substitution, 89 (32.1%) had g.10199A>C, and 188 (67.9%) had g.10199A>U nucleotide mutations. Only 2 sequences had g.10199A>G transitions despite transitions generally occurring more frequently than transversions, which indicates ensitrelvir exerts high selective pressure on SARS-CoV-2 in COVID-19 patients. The number of virus sequences with M49L substitutions began to increase in June, peaked in September, and then decreased in November of 2023, a pattern corresponding to the number of COVID-19 cases observed throughout Japan during that period ( Figure ). In Japan, the monthly occurrence rate of ensitrelvir-resistant SARS-CoV-2 infections was significantly higher during the 9 months after initiating widespread ensitrelvir prescriptions than during the preceding period ( Appendix Figure 1).

We constructed a phylogenetic tree as described previously ( 9 ). We downloaded whole-genome sequences from 277 SARS-CoV-2 mutants collected globally during March 31–December 31, 2023, and constructed the tree by using Nextstrain ( https://www.nextstrain.org ) and 570 reference genomes ( Appendix Figure 2). Single sporadic occurrences of ensitrelvir-resistant mutants that were not linked to each other in the phylogenetic tree were counted if only 1 case occurred in a clade or if 1 case occurred > 2 segments downstream of different branches from other cases belonging to the same clade, as described previously ( 9 ). Sporadic occurrence of g.10199A>C was detected 24 times and g.10199A>U was detected 22 times.

Although SARS-CoV-2 g.10199A>C and g.10199A>U mutations were detected nationwide in Japan, they were more frequent in populated metropolitan areas ( Appendix Figure 3). Sporadic occurrence of mutants not linked to human-to-human virus transmission within a prefecture was defined as detection of 1 genome with either the g.10199A>C or g.10199A>U mutation or defined as detection of 1 mutant genome collected >1 month apart from others. We considered > 105 genome mutations, 46 with g.10199A>C and 59 with g.10199A>U, to be sporadic occurrences ( Appendix Figure 3), suggesting that ensitrelvir-resistant SARS-CoV-2 emerges frequently in Japan.

In conclusion, COVID-19 patients in Japan are usually prescribed ensitrelvir immediately after receiving positive results from a rapid immunochromatographic SARS-CoV-2 test. The Japan Ministry of Health, Labour and Welfare has conducted surveillance by using next-generation sequencing to enable rapid detection of drug-resistant SARS-CoV-2 ( 10 ). We examined the occurrence of ensitrelvir-resistant SARS-CoV-2 after widespread ensitrelvir prescription in Japan. Replication of those ensitrelvir-resistant mutant viruses in individual patients is thought to be driven predominantly by selective pressure exerted by the drug, leading to sporadic occurrence. The decreased occurrence of ensitrelvir-resistant SARS-CoV-2 after October 1, 2023, might be because patients are required to pay a portion of their medical costs, which could thereby decrease the number of ensitrelvir prescriptions. Increasing use of ensitrelvir worldwide will likely increase the frequency of mutations in SARS-CoV-2 causing ensitrelvir resistance. Ongoing genome surveillance using next-generation sequencing is required to monitor emergence of SARS-CoV-2 mutants that are resistant to anticoronaviral drugs.

Dr. Doi was a researcher at the Japan National Institute of Infectious Diseases in Tokyo during this work. His research interests focus on the mechanisms underlying emergence of drug-resistant viruses.
