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

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.

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.
