APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association, (6th ed., 2nd printing).

General APA Guidelines
Your essay should be typed and double-spaced on standard-sized paper (8.5" x 11"), with 1" margins on all sides. You should use a clear font that is highly readable. APA recommends using 12 pt. Times New Roman font.
Include a page header (also known as the "running head") at the top of every page. To create a page header/running head, insert page numbers flush right. Then type "TITLE OF YOUR PAPER" in the header flush left using all capital letters. The running head is a shortened version of your paper's title and cannot exceed 50 characters including spacing and punctuation.
Major Paper Sections
Your essay should include four major sections: the Title Page, Abstract, Main Body, and References.
The title page should contain the title of the paper, the author's name, and the institutional affiliation. Include the page header (described above) flush left with the page number flush right at the top of the page. Please note that on the title page, your page header/running head should look like this:
Running head: TITLE OF YOUR PAPER
Pages after the title page should have a running head that looks like this:
TITLE OF YOUR PAPER
After consulting with publication specialists at the APA, OWL staff learned that the APA 6th edition, first printing sample papers have incorrect examples of running heads on pages after the title page. This link will take you to the APA site where you can find a complete list of all the errors in the APA's 6th edition style guide.
Type your title in upper and lowercase letters centered in the upper half of the page. APA recommends that your title be no more than 12 words in length and that it should not contain abbreviations or words that serve no purpose. Your title may take up one or two lines. All text on the title page, and throughout your paper, should be double-spaced.
Beneath the title, type the author's name: first name, middle initial(s), and last name. Do not use titles (Dr.) or degrees (PhD).
Beneath the author's name, type the institutional affiliation, which should indicate the location where the author(s) conducted the research.

Begin a new page. Your abstract page should already include the page header (described above). On the first line of the abstract page, center the word “Abstract” (no bold, formatting, italics, underlining, or quotation marks).
Beginning with the next line, write a concise summary of the key points of your research. (Do not indent.) Your abstract should contain at least your research topic, research questions, participants, methods, results, data analysis, and conclusions. You may also include possible implications of your research and future work you see connected with your findings. Your abstract should be a single paragraph, double-spaced. Your abstract should be between 150 and 250 words.
You may also want to list keywords from your paper in your abstract. To do this, indent as you would if you were starting a new paragraph, type Keywords: (italicized), and then list your keywords. Listing your keywords will help researchers find your work in databases.

APA format is the official style of the American Psychological Association and is use in psychology writing as well as other social sciences. These style guidelines specify different aspects of a document's presentation and layout, including how pages are structured, the organization of references, and how citations are made. This format also stipulates the use of an abstract designed to very briefly summarize the key details contained in a paper without providing too much detail.
Why Is an Abstract Important In APA Format?
While it is sometimes overlooked or only an afterthought, an abstract is an important part of any academic or professional paper. This brief overview serves as a summary of what your paper contains, so it should succinctly and accurately represent what your paper is about and what the reader can expect to find.
Fortunately, by following a few simple guidelines, you can create an abstract that generates interest in your work and help readers quickly learn if the paper will be of interest to them.
The Basics of an APA Format Abstract
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. The APA publication manual suggests that your abstract should function much like your title page—it should allow the person reading it too quickly determine what your paper is all about.
The APA manual also states that the abstract is the single most important paragraph in your entire paper. It is the first thing that most people will read, and it is usually what informs their decision to read the rest of your paper. A good abstract lets the reader know that your paper is worth reading.
According to the official guidelines of the American Psychological Association, a good 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.
- Objective and accurate. The abstract's purpose is to report rather than provide commentary. It should also accurately reflect what your paper is about. Only include information that is also included in the body of your paper.
How to Write an Abstract
- First, write your paper. While the abstract will be at the beginning of your paper, it should be the last section that 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 and place your running head and the page number 2 in the top right-hand corner. You should also center the word "Abstract" at the top of the page.
- Keep it short. According to the APA style manual, an abstract should be between 150 to 250 words. Exact word counts can 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 also be written as only one paragraph with no indentation. In order to succinctly describe your entire paper, you will need to determine which elements are the most important.
- 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. 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.
Things to Consider When Writing an Abstract
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 abstract of an experimental report:
- Begin by identifying the problem.
- Describe the participants in the study.
- Briefly, describe the study method used.
- Give the basic findings.
- Provide any conclusions or implications of the study.
For an abstract of a meta-analysis or literature review:
- Describe the problem of interest.
- Explain the criteria that were used to select the studies included in the paper.
- Identify the participants in the studies.
- Provide the main results.
- Describe any conclusions or implications.
How Long Should Your Abstract Be?
The sixth-edition APA manual suggests that an abstract be between 150 and 250 words. However, they note that the exact requirements vary from one journal to the next. If you are writing the abstract for a class, you might want to check with your instructor to see if he or she has a specific word count in mind.
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.
In order to ensure that all of your APA formatting is correct, consider consulting a copy of the Publication Manual of the American Psychological Association.
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. It may not take a lot of time to write, but careful attention to detail can ensure that your abstract does a good job representing the contents of your paper.
Some more tips that might help you get your abstract in tip-top shape:
- Look in academic psychology journals for examples of abstracts.
- Keep on hand a copy of a style guide published by the American Psychological Association for reference.
- If possible, take your paper to your school's writing lab for assistance.
