The majority of social, behavioral, biological, and clinical journals follow the conventional structured abstract form with the following four major headings (or variations of these headings):
OBJECTIVE (Purpose; aim; goal): Tells reader the purpose of your research and the questions it intends to answer
METHODS (Setting; study design; participants): Explains the methods and process so that other researchers can assess, review, and replicate your study.
RESULTS (Findings; outcomes): Summarizes the most important findings of your study
CONCLUSIONS (Discussion; implications; further recommendations): Summarizes the interpretation and implications of these results and presents recommendations for further research
Guidelines for Structured Abstracts*
- Total Word Count: ~200-300 words (depending on the journal)
- Content: Abstract should reflect only the contents of the original paper (no cited work)
* Always follow the formatting guidelines of the journal to which you are submitting your paper.
