How to Write an Abstract for an Essay, Dissertation, or Paper

An abstract is the front door to your research. Many readers will decide whether to read a dissertation or paper based on the abstract alone. A well-written abstract summarises the research question, method, findings, and implications in 150–300 words — complete enough to stand alone, concise enough to read quickly.

What an abstract must include

A standard academic abstract covers five elements:

1. Background / context — What is the research area and why does it matter? (1–2 sentences)
2. Research question / aim — What specific question does this work address? (1 sentence)
3. Method — How was the question investigated? (1–2 sentences — omit for theoretical or humanities work)
4. Findings / argument — What were the main results or central claim? (2–3 sentences)
5. Conclusions / implications — What does this mean? What follows from the findings? (1–2 sentences)

Not all abstracts need all five. Humanities dissertations often omit the methods section and give more space to the argument. Scientific abstracts typically follow this structure closely. Theoretical papers may have only background, question, argument, and implications.

Worked examples

Dissertation abstract (social sciences, 270 words)

This dissertation examines the relationship between digital media use and academic performance among undergraduate students in the UK, with a focus on the moderating role of self-regulation capacity. While the relationship between screen time and wellbeing has attracted considerable attention in recent years, the specific effects on academic outcomes — and the conditions under which those effects are positive or negative — remain insufficiently understood.

Using a mixed-methods design combining a survey of 312 students at a UK research university with 18 semi-structured interviews, the study finds that the relationship between digital media use and academic performance is not linear but strongly moderated by how digital tools are used. Students who use digital tools instrumentally — for academic search, note-taking, and timed study — report significantly better academic outcomes than those who use identical technologies passively (social media browsing, streaming). Self-regulation capacity predicts which pattern of use students adopt.

These findings suggest that institutional interventions targeting total screen time are poorly directed. The relevant variable is not quantity of digital media use but the self-regulatory context in which it occurs. Implications for study skills support programmes and academic induction policies are discussed.

Research paper abstract (psychology, 200 words)

Retrieval practice — being tested on learned material — has been shown to produce stronger long-term retention than re-reading in laboratory settings (Roediger & Karpicke, 2006). However, whether this advantage persists under conditions more representative of educational contexts remains unclear.

This study compared retrieval practice with re-reading in a field experiment conducted in a secondary school setting (N = 147, ages 15–16). Students studied a biology unit under one of three conditions: massed re-reading, distributed re-reading, or distributed retrieval practice. Retention was assessed at 1-week and 4-week delays using free recall and multiple-choice tests.

Distributed retrieval practice produced significantly higher free recall scores at both delay intervals (d = 0.62 at 1 week, d = 0.71 at 4 weeks). The advantage over distributed re-reading, while smaller than laboratory estimates, was consistent across both test formats and all ability quartiles. These results support the practical application of retrieval practice in classroom settings and suggest that the laboratory-to-classroom translation of the testing effect is more robust than previously assumed.

Humanities dissertation abstract (200 words)

This dissertation examines the representation of unreliable memory in Ian McEwan's novel Atonement (2001) and its 2007 film adaptation directed by Joe Wright. Existing scholarship has focused primarily on either the novel's metafictional self-consciousness or the film's cinematographic innovations; this analysis brings the two together through the lens of memory studies.

Drawing on theories of autobiographical memory from psychology (Schacter, 2001) and literary theories of unreliable narration (Booth, 1961; Nünning, 1999), the dissertation argues that both the novel and the film use their medium's specific representational resources to dramatise the same epistemological claim: that memory is reconstructive rather than reproductive, and that this reconstruction is always motivated by the needs of the present rather than fidelity to the past.

The analysis reveals that Wright's adaptation is not merely a translation of McEwan's narrative but an extension of its argument into a different representational register. The comparative reading clarifies what is specific to literary versus cinematic memory representation — and why Briony's unreliability unsettles readers and viewers in different ways.

Abstract formatting

• No citations in most abstracts (you are summarising your own work)
• No section headings (the abstract is a single paragraph — or structured paragraphs in some disciplines)
• No new information: the abstract summarises only what is in the document
• Keywords may be listed below the abstract (5–8 keywords separated by commas)
• Placed after the title page and acknowledgements, before the table of contents (in dissertations)

Common abstract mistakes

Writing it first — The abstract must describe actual findings, not intended ones. Always write it last.

Copying from the introduction — The abstract is a summary of the whole piece, not a paraphrase of the introduction. It must include the findings.

Too long — At over 350 words, most abstracts are padded. Be ruthless about concision.

Incomplete — An abstract that stops after the research question without stating the main findings leaves the reader without the key information.
