A dissertation abstract is a short, stand-alone summary that states your study's aim, methods, key findings, and contribution to knowledge.
For Vietnamese postgraduate researchers writing in English, the abstract is the most-read and least-rehearsed part of a thesis — the few hundred words an examiner, a database, and a future reader meet first. This guide answers the seven questions Vietnamese master's and doctoral students ask MAAS mentors most when they compress an entire thesis into one paragraph.

What is a dissertation abstract actually for?
Direct answer: The abstract is a self-contained miniature of the whole thesis that lets a reader decide, in under a minute, what you studied, how, what you found, and why it matters. It is read first, indexed by databases, and quoted in search results — so it works as both a summary and a gateway to the work.
Evidence: Swales and Feak (2009) describe the abstract as a distinct genre that must stand alone and make sense without the thesis attached. Hyland (2004) shows abstracts are not neutral summaries but persuasive, gatekeeping texts: across disciplines, writers use them to promote the significance of their work and win the reader's attention.
Example: A MAAS-coached master's student in management wrote an abstract that described her topic and aim but stopped before the results. Her mentor noted that a reader scanning a database would never learn what she had found — and the paragraph was rebuilt so findings and contribution carried the most words.
What moves should a dissertation abstract contain?
Direct answer: A complete abstract moves through a recognisable sequence: situate the research, state the purpose, describe the method, summarise the main results, and state the contribution. Naming each move as you draft stops the abstract from spending all its words on background and arriving at the findings too late, or not at all.
Evidence: dos Santos (1996) identified a five-move structure for research abstracts — situating the research, presenting it, describing the methodology, summarising the results, and discussing the research. Pho (2008), analysing thirty abstracts in applied linguistics and educational technology, found three of these moves obligatory in practice: presenting the research, describing the methodology, and summarising the results.
Example: A Vietnamese doctoral candidate in education had an abstract that was two-thirds background. Her MAAS mentor used the move table below as a budget — one or two sentences per move — and the rewritten version reached the method by sentence three and closed on a clear contribution.
| Move (dos Santos, 1996) | What you write | Typical length |
|---|---|---|
| 1 — Situate the research | The problem and why it matters | 1 sentence |
| 2 — Present the research | Your aim, question, or hypothesis | 1 sentence |
| 3 — Describe the methodology | Design, data, and analysis | 1–2 sentences |
| 4 — Summarise the results | Your main findings, concretely | 2–3 sentences |
| 5 — Discuss the research | Contribution, implication, or recommendation | 1 sentence |
How long should a dissertation abstract be, and how is it formatted?
Direct answer: Most universities cap a dissertation abstract at roughly 250–350 words, set on its own page after the title page, written as one or a few unbroken paragraphs without citations, tables, or undefined abbreviations. Always follow your department's stated word limit over any general figure.
Evidence: The APA Publication Manual (American Psychological Association, 2020) sets a typical abstract limit near 250 words and asks for prose that is accurate, non-evaluative, coherent, and concise, with keywords beneath. Swales and Feak (2009) note that length conventions vary by field, which is why the binding number is the one in your university's thesis regulations.
Example: A MAAS client in public health wrote a 600-word abstract her institution's template would have truncated. Her mentor mapped the five moves onto the 300-word limit, cutting method detail that belonged in chapter three, and the abstract fit the rule while keeping every essential claim.
| Level / type | Common word range | Notes |
|---|---|---|
| Master's dissertation abstract | 150–300 words | Check the department template first |
| PhD thesis abstract | 250–350 words | Some universities allow up to 500 |
| Journal article abstract | 150–250 words | Follows each journal's author guidelines |
| Structured abstract (some fields) | Labelled headings | Background, Methods, Results, Conclusion |
How do you write each move — background, aim, method, results, conclusion?
Direct answer: Write the abstract move by move in plain past tense: one sentence of context, one naming your aim, one or two on what you did, two or three on concrete results, and a final sentence on what your study contributes. Lead with what is new, not with how long the field has existed.
Evidence: Lorés (2004) found that research abstracts tend to follow one of two organisations — an informational pattern mirroring the introduction-method-results-conclusion shape, or a more indicative, descriptive pattern — and that the informational, results-forward type communicates a study's value most directly. Swales and Feak (2012) stress that abstracts work best when each sentence advances the reader rather than restating the title.
Example: A Vietnamese master's candidate in finance opened with three sentences on the importance of his sector. His MAAS mentor cut them to one and gave the space to a specific results sentence — a measured effect size rather than "significant findings" — so the abstract finally told the reader what the study established.
When should you write the abstract, and how do you condense a whole thesis?
Direct answer: Write the abstract last, once your results and conclusion are stable, then build it from the topic sentences of each chapter rather than from memory. Drafting it early forces you to summarise a thesis you have not finished — which is why early abstracts often promise findings the final study does not deliver.
Evidence: Swales and Feak (2009) treat the abstract as a text written in reflection on a completed piece, distilled from the work rather than composed alongside it. Their graduate-writing guidance (Swales & Feak, 2012) recommends assembling a summary from a paper's existing key sentences, then editing for flow — a reliable way to compress without losing the argument.
Example: A MAAS doctoral client kept rewriting her abstract throughout her candidature, and none matched her final results. Her mentor had her extract one sentence from each chapter's opening, stitch them into a draft, then polish — a half-day task that replaced months of guesswork.
What are keywords, and how do you choose them for discoverability?
Direct answer: Keywords are the handful of terms under the abstract that databases use to surface your thesis to the right readers. Choose words a searcher in your field would actually type — your method, population, context, and core concept — and avoid words already in the title, which add nothing to retrieval.
Evidence: The APA Publication Manual (American Psychological Association, 2020) instructs authors to follow the abstract with keywords that capture the article's most important concepts for indexing and search. dos Santos (1996) and Hyland (2004) both show the abstract is the unit databases and readers scan first, which makes its terminology — not just its prose — part of whether the work is found at all.
Example: A Vietnamese researcher's thesis on rural credit used only broad terms like "economics" and "Vietnam." Her MAAS mentor added the specific method and population, and the abstract became findable by the precise readers most likely to cite it.
What abstract mistakes do Vietnamese and other ESL researchers make most?
Direct answer: The most common pattern in second-language abstracts is too much background and too little result — the writer establishes the field thoroughly but states the actual findings vaguely. Other frequent issues are the missing contribution move, over-hedged claims, and copying whole sentences from the introduction instead of distilling them.
Evidence: Pho (2008), studying abstracts from non-Anglophone contexts, found the results-summarising move present but variably realised, and authorial stance often muted. Paltridge and Starfield (2019) note that second-language thesis writers tend to master the descriptive, summarising moves while underplaying the evaluative move that states a study's significance.
Example: A Vietnamese master's candidate's abstract named her topic and method clearly but never said what her data showed. Her MAAS mentor applied a one-sentence checklist — "this study found that…" — and the finding buried across her results chapter finally appeared where readers look for it first.
Frequently asked questions
How long should a dissertation abstract be?
Most universities set a limit between 150 and 350 words depending on level and discipline, with PhD abstracts usually allowed more room than master's. Treat any general figure as a guide and follow your department's thesis regulations and template, which state the binding word limit.
Should the abstract include citations or references?
Usually not. An abstract is meant to stand alone, so most guidelines ask you to avoid citations, footnotes, and references within it. If a particular field or journal expects a citation, follow that specific instruction, but for a dissertation abstract the default is none.
When in the writing process should I write the abstract?
Write it last, after your results and conclusion are settled. Composing the abstract early forces you to summarise findings you have not finalised, which usually means rewriting it later anyway. Building it from your finished chapters is faster and more accurate.
What is the difference between an abstract and an introduction?
The abstract summarises the entire thesis, including results and conclusion, in a few hundred words and stands alone. The introduction opens the thesis, sets up the problem and questions, and does not reveal the findings. The abstract reports outcomes; the introduction sets up the journey.
What is a structured abstract?
A structured abstract uses labelled headings such as Background, Methods, Results, and Conclusion instead of a single paragraph. It is common in health and some social sciences. Check whether your discipline or target journal requires this format before choosing between structured and unstructured.
