What Should a Dissertation Abstract Include?

It should not include citations, tables, figures, or information not already in the dissertation.

3. State your aims: Briefly state what your dissertation set out to achieve.
4. Describe your methodology: In one or two sentences, describe how you conducted your research.
5. Summarise your findings: Highlight the most important results — the findings that directly answer your research questions.

7. Check the word count: Stay within your university’s specified word limit, typically 150–350 words.

Common Mistakes When Writing an Abstract

A well-crafted dissertation abstract can make a powerful first impression on your examiners. One of the most common mistakes students make is summarising each chapter individually rather than presenting the research as a unified whole. Your abstract should read as a standalone piece — someone should be able to understand your research question, methodology, and findings just by reading it. Many UK students struggle with the required word count. Undergraduate and Master’s dissertations typically require an abstract of 150–300 words, while PhD theses may need 300–500 words. Always check your university guidelines before finalising your submission. Tense is another frequent problem when writing your dissertation abstract. Use past tense to describe what you did (“This study examined…”) and present tense for your conclusions (“The findings suggest…”). A polished abstract demonstrates academic maturity — a quality UK examiners value highly.

Quick Checklist Before Submission

• Does your abstract state the research problem clearly?
• Have you included the research methodology used?
• Does the abstract summarise the key findings and conclusions?
• Is the word count within your university’s specified range?
• Have you written your dissertation abstract last, after completing all other chapters?

Common Dissertation Abstract Mistakes to Avoid

Even students who have produced a strong dissertation often submit an abstract that does not do justice to their work. Understanding the most frequent mistakes makes it significantly easier to produce an abstract that reads as a polished, self-contained summary of your research.

Including information not in the dissertation: Every statement in your abstract must be substantiated by content somewhere in the body of the dissertation. An abstract that makes claims or raises questions that are not addressed in the research itself is misleading and will confuse readers who go on to read the full text.

Being too vague: Abstracts that describe a study in general terms without providing specific findings or conclusions are frustrating to read and fail to communicate the value of the research. “The findings have implications for practice” is not informative; “the findings suggest that X approach improves Y outcome in Z population by approximately 15%” is. Be as specific as your word limit allows.

Excessive length: Most UK university dissertation abstracts have a specified word limit—commonly 150 to 300 words. Exceeding this limit is a presentational error that can result in mark deductions. Write a first draft without worrying about length, then edit rigorously: remove repetition, condense explanations, and eliminate any information that is not essential for understanding the study’s purpose, approach, and findings.

Passive, impersonal language that obscures agency: While academic conventions vary by discipline, overly passive constructions can make an abstract read as flat and unclear. Compare “A sample of 120 participants was recruited” (acceptable) with “The research was conducted in which participants were identified through a process” (unclear). Aim for clarity above all: readers should be able to understand exactly what you did and found within the abstract’s word limit.

Abstract Writing Tips for Different Types of Dissertation

The specific content of a dissertation abstract varies depending on the type of research conducted. Qualitative, quantitative, and mixed-methods dissertations each require slightly different emphases.

For quantitative dissertations, the abstract should specify the research design (e.g., cross-sectional survey, randomised controlled trial, secondary data analysis), the sample size and characteristics, the key variables measured, the main statistical findings (including significance levels where relevant), and the principal conclusion.

For qualitative dissertations, the abstract should describe the methodological approach (e.g., thematic analysis of semi-structured interviews, grounded theory, ethnographic observation), the number of participants and sampling strategy, the key themes or findings that emerged from the data, and the interpretive conclusions drawn.

For literature reviews (systematic or narrative), the abstract should explain the review’s scope and research question, the databases and search terms used, the number of studies included after screening, the main themes or findings synthesised across the literature, and the implications for practice or future research.

As with any element of your dissertation, a well-written abstract benefits from external review before submission. If you would like professional feedback on whether your abstract accurately and effectively represents your research, expert academic editing can provide a final check that ensures your dissertation is presented with the clarity, precision, and professionalism it deserves.
