Writing an Abstract for Your Research Paper

Definition and Purpose of Abstracts

An abstract is a short summary of your (published or unpublished) research paper, usually about a paragraph (c. 6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes:

• an abstract lets readers get the gist or essence of your paper or article quickly, in order to decide whether to read the full paper;
• an abstract prepares readers to follow the detailed information, analyses, and arguments in your full paper;
• and, later, an abstract helps readers remember key points from your paper.

It’s also worth remembering that search engines and bibliographic databases use abstracts, as well as the title, to identify key terms for indexing your published paper. So what you include in your abstract and in your title are crucial for helping other researchers find your paper or article.

If you are writing an abstract for a course paper, your professor may give you specific guidelines for what to include and how to organize your abstract. Similarly, academic journals often have specific requirements for abstracts. So in addition to following the advice on this page, you should be sure to look for and follow any guidelines from the course or journal you’re writing for.

The Contents of an Abstract

Abstracts contain most of the following kinds of information in brief form. The body of your paper will, of course, develop and explain these ideas much more fully. As you will see in the samples below, the proportion of your abstract that you devote to each kind of information—and the sequence of that information—will vary, depending on the nature and genre of the paper that you are summarizing in your abstract. And in some cases, some of this information is implied, rather than stated explicitly. The Publication Manual of the American Psychological Association , which is widely used in the social sciences, gives specific guidelines for what to include in the abstract for different kinds of papers—for empirical studies, literature reviews or meta-analyses, theoretical papers, methodological papers, and case studies.

Here are the typical kinds of information found in most abstracts:

• the context or background information for your research; the general topic under study; the specific topic of your research
• the central questions or statement of the problem your research addresses
• what’s already known about this question, what previous research has done or shown
• the main reason(s) , the exigency, the rationale , the goals for your research—Why is it important to address these questions? Are you, for example, examining a new topic? Why is that topic worth examining? Are you filling a gap in previous research? Applying new methods to take a fresh look at existing ideas or data? Resolving a dispute within the literature in your field? . . .
• your research and/or analytical methods
• your main findings , results , or arguments
• the significance or implications of your findings or arguments.

Your abstract should be intelligible on its own, without a reader’s having to read your entire paper. And in an abstract, you usually do not cite references—most of your abstract will describe what you have studied in your research and what you have found and what you argue in your paper. In the body of your paper, you will cite the specific literature that informs your research.

When to Write Your Abstract

Although you might be tempted to write your abstract first because it will appear as the very first part of your paper, it’s a good idea to wait to write your abstract until after you’ve drafted your full paper, so that you know what you’re summarizing.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts.

Choosing Verb Tenses within Your Abstract

The social science sample (Sample 1) below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study. That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study. The authors use the past tense to describe previous research.

The humanities sample (Sample 2) below uses the past tense to describe completed events in the past (the texts created in the pulp fiction industry in the 1970s and 80s) and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article.

The science samples (Samples 3 and 4) below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found. In their rationale or justification for their research (what remains to be done), they use the present tense. They also use the present tense to introduce their study (in Sample 3, “Here we report . . .”) and to explain the significance of their study (In Sample 3, This reprogramming . . . “provides a scalable cell source for. . .”).

Sample Abstract 4, a Structured Abstract

Reporting results about the effectiveness of antibiotic therapy in managing acute bacterial sinusitis, from a rigorously controlled study

Note: This journal requires authors to organize their abstract into four specific sections, with strict word limits. Because the headings for this structured abstract are self-explanatory, we have chosen not to add annotations to this sample abstract.

Wald, Ellen R., David Nash, and Jens Eickhoff. “Effectiveness of Amoxicillin/Clavulanate Potassium in the Treatment of Acute Bacterial Sinusitis in Children.” Pediatrics , vol. 124, no. 1, 2009, pp. 9-15.

“OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.

METHODS : This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or ≥6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children’s conditions were rated as cured, improved, or failed according to scoring rules.

RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 6630 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4(14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.

CONCLUSIONS : ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cures and fewer failures than placebo, according to parental report of time to resolution.” (9)

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.

• 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.

What this handout is about

This handout provides definitions and examples of the two main types of abstracts: descriptive and informative. It also provides guidelines for constructing an abstract and general tips for you to keep in mind when drafting. Finally, it includes a few examples of abstracts broken down into their component parts.

What is an abstract?

An abstract is a self-contained, short, and powerful statement that describes a larger work. Components vary according to discipline. An abstract of a social science or scientific work may contain the scope, purpose, results, and contents of the work. An abstract of a humanities work may contain the thesis, background, and conclusion of the larger work. An abstract is not a review, nor does it evaluate the work being abstracted. While it contains key words found in the larger work, the abstract is an original document rather than an excerpted passage.

Why write an abstract?

You may write an abstract for various reasons. The two most important are selection and indexing. Abstracts allow readers who may be interested in a longer work to quickly decide whether it is worth their time to read it. Also, many online databases use abstracts to index larger works. Therefore, abstracts should contain keywords and phrases that allow for easy searching.

Say you are beginning a research project on how Brazilian newspapers helped Brazil’s ultra-liberal president Luiz Ignácio da Silva wrest power from the traditional, conservative power base. A good first place to start your research is to search Dissertation Abstracts International for all dissertations that deal with the interaction between newspapers and politics. “Newspapers and politics” returned 569 hits. A more selective search of “newspapers and Brazil” returned 22 hits. That is still a fair number of dissertations. Titles can sometimes help winnow the field, but many titles are not very descriptive. For example, one dissertation is titled “Rhetoric and Riot in Rio de Janeiro.” It is unclear from the title what this dissertation has to do with newspapers in Brazil. One option would be to download or order the entire dissertation on the chance that it might speak specifically to the topic. A better option is to read the abstract. In this case, the abstract reveals the main focus of the dissertation:

This dissertation examines the role of newspaper editors in the political turmoil and strife that characterized late First Empire Rio de Janeiro (1827-1831). Newspaper editors and their journals helped change the political culture of late First Empire Rio de Janeiro by involving the people in the discussion of state. This change in political culture is apparent in Emperor Pedro I’s gradual loss of control over the mechanisms of power. As the newspapers became more numerous and powerful, the Emperor lost his legitimacy in the eyes of the people. To explore the role of the newspapers in the political events of the late First Empire, this dissertation analyzes all available newspapers published in Rio de Janeiro from 1827 to 1831. Newspapers and their editors were leading forces in the effort to remove power from the hands of the ruling elite and place it under the control of the people. In the process, newspapers helped change how politics operated in the constitutional monarchy of Brazil.

From this abstract you now know that although the dissertation has nothing to do with modern Brazilian politics, it does cover the role of newspapers in changing traditional mechanisms of power. After reading the abstract, you can make an informed judgment about whether the dissertation would be worthwhile to read.

Besides selection, the other main purpose of the abstract is for indexing. Most article databases in the online catalog of the library enable you to search abstracts. This allows for quick retrieval by users and limits the extraneous items recalled by a “full-text” search. However, for an abstract to be useful in an online retrieval system, it must incorporate the key terms that a potential researcher would use to search. For example, if you search Dissertation Abstracts International using the keywords “France” “revolution” and “politics,” the search engine would search through all the abstracts in the database that included those three words. Without an abstract, the search engine would be forced to search titles, which, as we have seen, may not be fruitful, or else search the full text. It’s likely that a lot more than 60 dissertations have been written with those three words somewhere in the body of the entire work. By incorporating keywords into the abstract, the author emphasizes the central topics of the work and gives prospective readers enough information to make an informed judgment about the applicability of the work.

When do people write abstracts?

• when submitting articles to journals, especially online journals
• when applying for research grants
• when writing a book proposal
• when completing the Ph.D. dissertation or M.A. thesis
• when writing a proposal for a conference paper
• when writing a proposal for a book chapter

Most often, the author of the entire work (or prospective work) writes the abstract. However, there are professional abstracting services that hire writers to draft abstracts of other people’s work. In a work with multiple authors, the first author usually writes the abstract. Undergraduates are sometimes asked to draft abstracts of books/articles for classmates who have not read the larger work.

Types of abstracts

There are two types of abstracts: descriptive and informative. They have different aims, so as a consequence they have different components and styles. There is also a third type called critical, but it is rarely used. If you want to find out more about writing a critique or a review of a work, see the UNC Writing Center handout on writing a literature review . If you are unsure which type of abstract you should write, ask your instructor (if the abstract is for a class) or read other abstracts in your field or in the journal where you are submitting your article.

Descriptive abstracts

A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract describes the work being abstracted. Some people consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short—100 words or less.

Informative abstracts

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the writer presents and explains all the main arguments and the important results and evidence in the complete article/paper/book. An informative abstract includes the information that can be found in a descriptive abstract (purpose, methods, scope) but also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of a longer work, it may be much less.

Here are examples of a descriptive and an informative abstract of this handout on abstracts . Descriptive abstract:

The two most common abstract types—descriptive and informative—are described and examples of each are provided.

Informative abstract:

Abstracts present the essential elements of a longer work in a short and powerful statement. The purpose of an abstract is to provide prospective readers the opportunity to judge the relevance of the longer work to their projects. Abstracts also include the key terms found in the longer work and the purpose and methods of the research. Authors abstract various longer works, including book proposals, dissertations, and online journal articles. There are two main types of abstracts: descriptive and informative. A descriptive abstract briefly describes the longer work, while an informative abstract presents all the main arguments and important results. This handout provides examples of various types of abstracts and instructions on how to construct one.

Which type should I use?

Your best bet in this case is to ask your instructor or refer to the instructions provided by the publisher. You can also make a guess based on the length allowed; i.e., 100-120 words = descriptive; 250+ words = informative.

How do I write an abstract?

The format of your abstract will depend on the work being abstracted. An abstract of a scientific research paper will contain elements not found in an abstract of a literature article, and vice versa. However, all abstracts share several mandatory components, and there are also some optional parts that you can decide to include or not. When preparing to draft your abstract, keep the following key process elements in mind:

• Reason for writing: What is the importance of the research? Why would a reader be interested in the larger work?
• Problem: What problem does this work attempt to solve? What is the scope of the project? What is the main argument/thesis/claim?
• Methodology: An abstract of a scientific work may include specific models or approaches used in the larger study. Other abstracts may describe the types of evidence used in the research.
• Results: Again, an abstract of a scientific work may include specific data that indicates the results of the project. Other abstracts may discuss the findings in a more general way.
• Implications: 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?

(This list of elements is adapted with permission from Philip Koopman, “How to Write an Abstract.” )

All abstracts include:

• A full citation of the source, preceding the abstract.
• The most important information first.
• The same type and style of language found in the original, including technical language.
• Key words and phrases that quickly identify the content and focus of the work.
• Clear, concise, and powerful language.

Abstracts may include:

• The thesis of the work, usually in the first sentence.
• Background information that places the work in the larger body of literature.
• The same chronological structure as the original work.

How not to write an abstract:

• Do not refer extensively to other works.
• Do not add information not contained in the original work.
• Do not define terms.

If you are abstracting your own writing

When abstracting your own work, it may be difficult to condense a piece of writing that you have agonized over for weeks (or months, or even years) into a 250-word statement. There are some tricks that you could use to make it easier, however.

Reverse outlining:

This technique is commonly used when you are having trouble organizing your own writing. The process involves writing down the main idea of each paragraph on a separate piece of paper– see our short video . For the purposes of writing an abstract, try grouping the main ideas of each section of the paper into a single sentence. Practice grouping ideas using webbing or color coding .

For a scientific paper, you may have sections titled Purpose, Methods, Results, and Discussion. Each one of these sections will be longer than one paragraph, but each is grouped around a central idea. Use reverse outlining to discover the central idea in each section and then distill these ideas into one statement.

Cut and paste:

To create a first draft of an abstract of your own work, you can read through the entire paper and cut and paste sentences that capture key passages. This technique is useful for social science research with findings that cannot be encapsulated by neat numbers or concrete results. A well-written humanities draft will have a clear and direct thesis statement and informative topic sentences for paragraphs or sections. Isolate these sentences in a separate document and work on revising them into a unified paragraph.

If you are abstracting someone else’s writing

When abstracting something you have not written, you cannot summarize key ideas just by cutting and pasting. Instead, you must determine what a prospective reader would want to know about the work. There are a few techniques that will help you in this process:

Identify key terms:

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.

Highlight key phrases and sentences:

Instead of cutting and pasting the actual words, try highlighting sentences or phrases that appear to be central to the work. Then, in a separate document, rewrite the sentences and phrases in your own words.

Don’t look back:

After reading the entire work, put it aside and write a paragraph about the work without referring to it. In the first draft, you may not remember all the key terms or the results, but you will remember what the main point of the work was. Remember not to include any information you did not get from the work being abstracted.

Revise, revise, revise

No matter what type of abstract you are writing, or whether you are abstracting your own work or someone else’s, the most important step in writing an abstract is to revise early and often. When revising, delete all extraneous words and incorporate meaningful and powerful words. The idea is to be as clear and complete as possible in the shortest possible amount of space. The Word Count feature of Microsoft Word can help you keep track of how long your abstract is and help you hit your target length.

Example 1: Humanities abstract

Kenneth Tait Andrews, “‘Freedom is a constant struggle’: The dynamics and consequences of the Mississippi Civil Rights Movement, 1960-1984” Ph.D. State University of New York at Stony Brook, 1997 DAI-A 59/02, p. 620, Aug 1998

This dissertation examines the impacts of social movements through a multi-layered study of the Mississippi Civil Rights Movement from its peak in the early 1960s through the early 1980s. By examining this historically important case, I clarify the process by which movements transform social structures and the constraints movements face when they try to do so. The time period studied includes the expansion of voting rights and gains in black political power, the desegregation of public schools and the emergence of white-flight academies, and the rise and fall of federal anti-poverty programs. I use two major research strategies: (1) a quantitative analysis of county-level data and (2) three case studies. Data have been collected from archives, interviews, newspapers, and published reports. This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement. The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.

Now let’s break down this abstract into its component parts to see how the author has distilled his entire dissertation into a ~200 word abstract.

Example 2: Science Abstract

Luis Lehner, “Gravitational radiation from black hole spacetimes” Ph.D. University of Pittsburgh, 1998 DAI-B 59/06, p. 2797, Dec 1998

The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.

This science abstract covers much of the same ground as the humanities one, but it asks slightly different questions.

Writing for Publication: Abstracts

An abstract is "a brief, comprehensive summary of the contents of the paper" (American Psychological Association [APA], 2020, p. 38). This summary is intended to share the topic, argument, and conclusions of a research study or course paper, similar to the text on the back cover of a book. When submitting your work for publication, an abstract is often the first piece of your writing a reviewer will encounter. An abstract may not be required for course papers.

Read on for more tips on making a good first impression with a successful abstract.

An abstract is a single paragraph preceded by the heading " Abstract ," centered and in bold font. The abstract does not begin with an indented line. APA (2020) recommends that abstracts should generally be less than 250 words, though many journals have their own word limits; it is always a good idea to check journal-specific requirements before submitting. The Writing Center's APA templates are great resources for visual examples of abstracts.

Abstracts use the present tense to describe currently applicable results (e.g., "Results indicate...") and the past tense to describe research steps (e.g., "The survey measured..."), and they do not typically include citations.

Key terms are sometimes included at the end of the abstract and should be chosen by considering the words or phrases that a reader might use to search for your article.

An abstract should include information such as

• The problem or central argument of your article
• A brief exposition of research design, methods, and procedures.
• A brief summary of your findings
• A brief summary of the implications of the research on practice and theory

It is also appropriate, depending on the type of article you are writing, to include information such as:

• Participant number and type
• Study eligibility criteria
• Limitations of your study
• Implications of your study's conclusions or areas for additional research

Your abstract should avoid unnecessary wordiness and focus on quickly and concisely summarizing the major points of your work. An abstract is not an introduction; you are not trying to capture the reader's attention with timeliness or to orient the reader to the entire background of your study. When readers finish reading your abstract, they should have a strong sense of your article's purpose, approach, and conclusions. The Walden Office of Research and Doctoral Services has additional  tutorial material on abstracts .

Clinical or Empirical Study Abstract Exemplar

In the following abstract, the article's problem is stated in red , the approach and design are in blue , and the results are in green .

End-stage renal disease (ESRD) patients have a high cardiovascular mortality rate. Precise estimates of the prevalence, risk factors and prognosis of different manifestations of cardiac disease are unavailable. In this study a prospective cohort of 433 ESRD patients was followed from the start of ESRD therapy for a mean of 41 months. Baseline clinical assessment and echocardiography were performed on all patients.  The major outcome measure was death while on dialysis therapy. Clinical manifestations of cardiovascular disease were highly prevalent at the start of ESRD therapy: 14% had coronary artery disease, 19% angina pectoris, 31% cardiac failure, 7% dysrhythmia and 8% peripheral vascular disease. On echocardiography 15% had systolic dysfunction, 32% left ventricular dilatation and 74% left ventricular hypertrophy. The overall median survival time was 50 months. Age, diabetes mellitus, cardiac failure, peripheral vascular disease and systolic dysfunction independently predicted death in all time frames. Coronary artery disease was associated with a worse prognosis in patients with cardiac failure at baseline. High left ventricular cavity volume and mass index were independently associated with death after two years. The independent associations of the different echocardiographic abnormalities were: systolic dysfunction--older age and coronary artery disease; left ventricular dilatation--male gender, anemia, hypocalcemia and hyperphosphatemia; left ventricular hypertrophy--older age, female gender, wide arterial pulse pressure, low blood urea and hypoalbuminemia. We conclude that clinical and echocardiographic cardiovascular disease are already present in a very high proportion of patients starting ESRD therapy and are independent mortality factors.

Literature Review Abstract Exemplar

In the following abstract, the purpose and scope of the literature review are in red , the specific span of topics is in blue , and the implications for further research are in green .

This paper provides a review of research into the relationships between psychological types, as measured by the Myers-Briggs Type Indicator (MBTI), and managerial attributes, behaviors and effectiveness. The literature review includes an examination of the psychometric properties of the MBTI and the contributions and limitations of research on psychological types. Next, key findings are discussed and used to advance propositions that relate psychological type to diverse topics such as risk tolerance, problem solving, information systems design, conflict management and leadership. We conclude with a research agenda that advocates: (a) the exploration of potential psychometric refinements of the MBTI, (b) more rigorous research designs, and (c) a broadening of the scope of managerial research into type.

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.

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.

An abstract summarizes, usually in one paragraph of 300 words or less, the major aspects of the entire paper in a prescribed sequence that includes: 1) the overall purpose of the study and the research problem(s) you investigated; 2) the basic design of the study; 3) major findings or trends found as a result of your analysis; and, 4) a brief summary of your interpretations and conclusions.

Importance of a Good Abstract

Sometimes your professor will ask you to include an abstract, or general summary of your work, with your research paper. The abstract allows you to elaborate upon each major aspect of the paper and helps readers decide whether they want to read the rest of the paper. Therefore, enough key information [e.g., summary results, observations, trends, etc.] must be included to make the abstract useful to someone who may want to examine your work.

How do you know when you have enough information in your abstract? A simple rule-of-thumb is to imagine that you are another researcher doing a similar study. Then ask yourself: if your abstract was the only part of the paper you could access, would you be happy with the amount of information presented there? Does it tell the whole story about your study? If the answer is "no" then the abstract likely needs to be revised.

Feak. Abstracts and the Writing of Abstracts . Ann Arbor, MI: University of Michigan Press, 2009.

Structure and Writing Style

I.  Types of Abstracts

To begin, you need to determine which type of abstract you should include with your paper. There are four general types.

Critical Abstract A critical abstract provides, in addition to describing main findings and information, a judgment or comment about the study’s validity, reliability, or completeness. The researcher evaluates the paper and often compares it with other works on the same subject. Critical abstracts are generally 400-500 words in length due to the additional interpretive commentary. These types of abstracts are used infrequently.

Descriptive Abstract A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarized. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less. Informative Abstract The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Highlight Abstract A highlight abstract is specifically written to attract the reader’s attention to the study. No pretense is made of there being either a balanced or complete picture of the paper and, in fact, incomplete and leading remarks may be used to spark the reader’s interest. In that a highlight abstract cannot stand independent of its associated article, it is not a true abstract and, therefore, rarely used in academic writing.

II.  Writing Style

Use the active voice when possible , but note that much of your abstract may require passive sentence constructions. Regardless, write your abstract using concise, but complete, sentences. Get to the point quickly and always use the past tense because you are reporting on a study that has been completed.

Abstracts should be formatted as a single paragraph in a block format and with no paragraph indentations. In most cases, the abstract page immediately follows the title page. Do not number the page. Rules set forth in writing manual vary but, in general, you should center the word "Abstract" at the top of the page with double spacing between the heading and the abstract. The final sentences of an abstract concisely summarize your study’s conclusions, implications, or applications to practice and, if appropriate, can be followed by a statement about the need for additional research revealed from the findings.

Composing Your Abstract

Although it is the first section of your paper, the abstract should be written last since it will summarize the contents of your entire paper. A good strategy to begin composing your abstract is to take whole sentences or key phrases from each section of the paper and put them in a sequence that summarizes the contents. Then revise or add connecting phrases or words to make the narrative flow clearly and smoothly. Note that statistical findings should be reported parenthetically [i.e., written in parentheses].

Before handing in your final paper, check to make sure that the information in the abstract completely agrees with what you have written in the paper. Think of the abstract as a sequential set of complete sentences describing the most crucial information using the fewest necessary words. The abstract SHOULD NOT contain:

• A catchy introductory phrase, provocative quote, or other device to grab the reader's attention,
• Lengthy background or contextual information,
• Redundant phrases, unnecessary adverbs and adjectives, and repetitive information;
• Acronyms or abbreviations,
• References to other literature [say something like, "current research shows that..." or "studies have indicated..."],
• Using ellipticals [i.e., ending with "..."] or incomplete sentences,
• Jargon or terms that may be confusing to the reader,
• Citations to other works, and
• Any sort of image, illustration, figure, or table, or references to them.

Writing Tip

Never Cite Just the Abstract!

Citing to just a journal article's abstract does not confirm for the reader that you have conducted a thorough or reliable review of the literature. If the full-text is not available, go to the USC Libraries main page and enter the title of the article [NOT the title of the journal]. If the Libraries have a subscription to the journal, the article should appear with a link to the full-text or to the journal publisher page where you can get the article. If the article does not appear, try searching Google Scholar using the link on the USC Libraries main page. If you still can't find the article after doing this, contact a librarian or you can request it from our free i nterlibrary loan and document delivery service .

How to Write an Abstract Within a Word Limit (Part I)

What is an Abstract in a Research Paper?

An abstract is a self-contained, short, and powerful statement that covers the main points of a piece of writing. Unlike executive summaries written for non-specialist audiences, abstracts use the same level of technical language and expertise found in the article itself. And unlike general summaries, which can be adapted in many ways to meet various readers’ and writers’ needs, abstracts are typically 150–250 words and have a fairly standard format.

An abstract is not a review, nor does it evaluate the work being abstracted. That is, the abstract is an original document rather than an excerpted passage.

Why is an Abstract Required?

You may be writing an abstract for various reasons. The two most important are

• Selection – to help readers decide if they want to read your article
• Indexing – for quick recovery and cross-referencing.

Many abstracts are published in abstract journals or in online databases without the complete paper itself. Thus, an abstract might serve as the only means by which a researcher determines what information a paper contains.

Therefore, although limited in word count, an abstract must do almost as much work as the multi-page paper that follows it. This means that it should, in most cases, include the following components: motivation, problem statement, approach, results, and conclusions. Each component is typically a single sentence or sometimes spreads across two sentences. Abstracts must also contain keywords and phrases that allow for easy searching.

Think of a half-dozen search phrases and keywords that people working in your field might use. Be sure that those exact phrases appear in your abstract, so that they will appear at the top of a search result listing.

How to Meet the Word Limit?

One of the most critical points to consider while writing an abstract is observing the word limit. Ignoring the limit often leads to the abstract being returned with a request to make it shorter. Reviewers say so easily, however, when abstracting your own work, it may be difficult to condense a piece of writing that you agonized over for weeks (or months or even years) into a 150- to 250-word statement. Described in this article are three simple steps to writing an abstract within a word limit .

The Word Count feature of MS Word can help you track the length of your abstract. Click on the status bar in the bottom left hand corner of the Word window. It will tell you the character count, word count, and number of lines and paragraphs.

Step 1: Write the “Best” First Draft

One way of writing an effective abstract is to start with a draft of the complete paper and apply the following treatment. At this stage, don’t be overly concerned about the length. Understanding what to write in the abstract of a research paper is crucial. Just make sure you include all the key information listed below:

• Highlight the objective and conclusion that are in the paper’s Introduction and Discussion.
• Bracket information in the Methods section of the paper that contains relevant keyword information.
• Highlight the results from the Discussion or Results section of the paper.
• Combine the above highlighted and bracketed information into a single paragraph. One way of doing this is to begin the first sentence with the general topic.
• Condense the bracketed information into key words and phrases that identify but do not explain the methods used.
• Delete extra words and phrases.
• Delete any irrelevant background information.
• Rephrase the first sentence so that it starts off with the new information contained in the paper, rather than with the phrase “this paper” or “this study.”
• Revise the paragraph so that the abstract conveys only essential information.

Step 2: Apply the “Avoid” Checklist

After completing the first draft, we need to ensure that no unnecessary content has been included in the abstract:

• Do not add information not contained in the original work.
• Avoid abbreviations or acronyms. Only define an abbreviation if the term appears multiple times in the abstract.
• Omit background information, literature review , and detailed description of methods.
• Avoid reference to other works.
• Omit bibliography or citations.
• Omit references, tables, and graphs.

In our next article , let’s look at the other ways you can further reduce the word count of your Abstract.

How Long Should an Abstract Be? Word Count & Length

The abstract is perhaps the most important section of your research paper. Apart from the title, it may be the only part of the paper anyone reads. Whether they read further  depends in part on how good an impression your abstract makes .

The abstract may also be the only part of your paper that has a word limit. Most word limits specify a maximum of  between 250 and 300 words , and some journals require that abstracts be as short as 150 words. Writing a great abstract is almost an art—but writing an abstract that meets word limits is, well, a  science .

 Why do journals impose abstract word limits?

There are several reasons your abstract needs to be short and concise. Journals want readers to buy your article, and they want other researchers to cite your study in their own articles. More citations means a higher impact factor for the journal. The best way to sell your study is to grab the reader’s attention with a great title and abstract. Finally, there is the issue of space. Journals want your abstract to fit on half a page so that a reader won’t have to scroll to read all of it.

When it comes to abstracts, less is more. Only essential information needs to be presented. A short, powerful abstract will draw readers into your research and help the journal attract more readers and receive more citations. The trick is how to trim your abstract to get under the word limit. Here are some time- and researcher-tested ways to pull that off.

Omit Needless Words and Adverbs

In their acclaimed guide to English writing,  The Elements of Style , William Strunk, Jr, and E. B. White teach the key to meeting abstract word limits: Omit needless words. Many writers, especially academic writers, pepper their writing with words that simply don’t need to be there.

A “hedge” is a word or phrase you use when you are concerned about making a claim instead of stating a fact. It’s always a good idea to be careful, especially in academic writing, but many authors use hedge words when they don’t need to. Among the most overused hedge words are the verbs “seem” and “appear.” In the examples below, you’ll see why taking away the hedge words does not alter the meaning.

Hedge : Maroney syndrome  seems   to impair quality of life. No Hedge : Maroney syndrome  impairs   quality of life.

Hedge : Ibuprofen  appears   to diminish pain in most patients. No Hedge : Ibuprofen  diminishes   pain in most patients.

In both pairs, the first and second sentences have essentially the same meaning, except that the second sentence omits the hedge word. Notice how the second examples are more powerful and straightforward without this extra verbiage.

Cutting out needless adverbs is another easy way to limit the number of words in an abstract.

With needless adverbs : We  slowly and carefully  dissected the vagus nerve. Without needless adverbs : We dissected the vagus nerve.

By definition, “dissection” is slow and careful (or  should  be!). Removing the needless adverbs “slowly” and “carefully’ leaves you with a sentence with the same meaning and three fewer words. Same your adverbs for situations in which they truly impact the meaning or have an impact on the reader or interpretation.

Remove Awkward and Unnecessary Transitions

Conjunctive adverbs are better known as “ transition terms ,” and although they can be very useful in creating structure and flow within the body of a paper, in the abstract they are often redundant or even incorrectly used. Among the more commonly used conjunctive adverbs are: however, moreover, therefore, furthermore, additionally, and thus.

The conjunction “moreover” is perhaps the most commonly used needless adverb in scientific papers. Some writers use it because they believe it makes them sound more “academic.” Others use it because they may know that it’s a grammatical faux-pas to start a sentence with the conjunction “And.” Nevertheless, “moreover” can virtually  always  be removed from a sentence without altering the meaning. Watch what happens when we remove the word “moreover from these sentences.

With a transition :  Moreover , we dissected the vagus nerve. Without a transition : We dissected the vagus nerve.

In the instance above, “moreover” does not really make sense as a transition term. Even other transition terms (furthermore, therefore, in addition, etc.) would be somewhat unnecessary when discussing how the study or experiment was performed.

With a transition :  Furthermore , patients with Boney-Maroney syndrome are likely to experience hot flashes and fatigue. Without a transition : Patients with Boney-Maroney syndrome are likely to experience hot flashes and fatigue.

Note that these two sentences have exactly the same meaning with and without the transition term “furthermore.”  These transitions can be much more useful in the longer sections of the paper’s body, especially in the Introduction and Discussion/Conclusion sections.

Use the Active Voice Instead of Passive Voice

One way to shorten your abstract is to apply a rule you might have learned in primary school: use active voice instead of passive voice . In active voice constructions, the subject carries the action. In passive voice, the subject is acted upon, usually by an unnamed actor. Scientists seem to be in love with the passive voice, as it can be found in many papers, simply adding to the word count and making the writing less engaging. Because of this longstanding convention, many believe it makes them sound more “scientific.” Others shun active voice because they feel as though it is too personal. That is a shame. Your sentences will often sound more convincing and powerful in active voice, as the following examples demonstrate:

Passive voice : Pituitary cells  were grown  in dishes that had been subjected to irradiation (12 words). Active voice :  We grew  pituitary cells in irradiated dishes (7 words). Passive voice : Three-hundred and forty-five patients  who had undergone  ovariectomy at our institution  were enrolled  in the present study (17 words). Active voice :  We enrolled   345 patients whom we had ovariectomized (eight words).

Remember, studies don’t conduct themselves;  scientists  conduct studies. Avoid using the passive voice in the abstract—save it for the Methods section!

Do not Include Statistical Methods or Findings in the Abstract

Most scientific articles include statistics. Usually, the statistical methods are described in detail in the Methods section of a paper. But many authors feel compelled for some reason to mention statistics in the abstract, perhaps to get the details out first. But unless your paper is primarily about statistics, it is best to keep statistics out of the abstract and stick to language that expresses the most important use and findings of the study. Not only do statistics add to your word count, but they also interrupt the flow of your argument. You certainly do not need to tell the reader what statistical tests you used or the version of the statistics program you used—that is what the Methods section is for. And never go into detail about EXACTLY which findings your study yielded—that is what the Results section is for.

Consent, Approval, and Other Info That Doesn’t Belong in an Abstract

Some authors place information about patient consent and institutional review board approval in the abstract. Whereas this information is indeed essential, it is not necessary to put it in the abstract. Like statistics, consent and approval statements interrupt the flow of your argument. Readers expect to find information about consent and approval in the Methods section. Leaving this out of your abstract will certainly free up your space to describe the importance of your study.

Abstract Word Limits Are not Targets

Keep in mind that a limit of 250 words does not mean that you should attempt to come as close as possible to the limit. The best abstracts include all essential information well before reaching word limit. Use the above tips to help you create a leaner, tighter abstract that will hook readers and entice them to read your full study.

Having trouble writing an abstract? You’re not alone.

Crafting an abstract can be problematic, especially when dealing with voluminous work. After all, converting a 100-page academic paper into 150 words is not an easy task. And this is where an abstract maker can help you immensely.

The amount of time you’ll save by relying on a machine to do the work for you is huge. Not to mention the result will be entirely error-free. No logical, grammatical, or other mistakes will spoil your piece.

Sounds interesting? Then, keep reading to learn more about abstracts and our generator.

An abstract is a brief summary of a work. Usually, it's a single paragraph containing 150 to 250 words. It describes all the key points and elements of an article, essay, or work of any other format.

Keep in mind that an abstract merely describes a text. It shouldn’t be an evaluation or an attempt to defend the paper. Instead, it’s just an overview.

Structure of an Abstract

An abstract is not a simple summary. It has a specific structure and should contain the following elements:

Remember that an abstract is separate from the rest of the paper. For the reader to get the complete picture of your research, your abstract must include everything listed above.

✍️ How to Write an Abstract

It can be tempting to go and write an abstract right away. But make sure to finish the planning of your work first. You want to write your abstract about your piece's contents, not build the contents around your abstract.

To make the writing process easier, divide it into 5 manageable steps:

• Check the requirements. First off, you need to know how much you are allowed to write. An average abstract is about 150-250 words long, but there is often a strict limit. Make sure to stay within it!
• Establish the goal and the problems of the research. The reader needs to know what your paper will be about right from the get-go. That’s why you need to formulate your thesis and showcase it first.
• Establish the methods. Tell the reader how you did your research. Don’t go in too deep: simply describe the methods without unnecessary details.
• Describe the results. Write a couple of sentences about the outcome of your investigation.
• Write a conclusion. Address the issue you established in the second step. You might also want to mention your work’s limitations regarding your research samples or methods. Try to give the reader a clear understanding of your goal and how you achieved it.

Abstract Writing Tips

Finally, we want to help you make your abstract truly amazing. Check out our best tips below:

• It's best to get to the point immediately and without adding any filler or unnecessary details.
• The less specific your abstract is, the better.
• Check out some examples before you start writing. Sometimes the best way to learn something is to watch how everyone else does it.
• Avoid long sentences or bizarre vocabulary to make an abstract paragraph as concise as possible.
• It’s a great idea to single out some keywords from your outline and put them into your abstract.
• Don't forget about formatting. Any serious academic work has its requirements. Make sure you check them before writing your piece.

Following these simple tips will make you a master of abstract writing.

✨ Free Abstract Sample

As an example, check out this abstract of the article “Bioeffcacy of Mentha piperita essential oil against dengue fever mosquito” by Sarita Kumar:

The Mentha balsamea, or peppermint plant, is a result of cross-breeding between spearmint and water mint. These plants are most commonly used in the area of repelling insects. The following research revolves around peppermint oil insect repellent and its development. As a part of an experiment, we obtained 25 grams of fresh peppermint and, after grinding it, put it in a glass jar with olive oil. The jar was then left for two days in a warm temperate. Next, the oil was strained with a cheesecloth, gathered, and diluted at 70%. It then got separated into three different spray bottles. The test was to put the spray sample into a jar with mosquitoes and equate the result to the same test with a commercial repellant. Thus, we challenged the stereotype of synthetic repellents being more efficient than their analogs made from natural materials.
