How to Write a Research Ethics Statement for Your Dissertation (2026)

Your research ethics statement is one of the most scrutinised passages in your entire dissertation. Examiners look for it in your methodology chapter as a signal that you conducted your research responsibly — that you protected your participants, sought the proper approvals, and understood your obligations under your institution’s research governance framework. Yet it is also one of the most poorly written sections in most student theses: vague, incomplete, or pasted in as an afterthought.

This guide explains exactly what your ethics statement needs to cover, how to write one that satisfies both your university’s research ethics committee and your examiner, and provides copy-paste templates you can adapt for common dissertation research designs. Whether you are writing for a UK REC, a US IRB, or an equivalent body, the core requirements are the same.

Quick Answer: A research ethics statement in a dissertation must state: (1) the ethics approval body and reference number, (2) how informed consent was obtained, (3) how participant anonymity/confidentiality was ensured, (4) how data was stored securely, (5) how participants’ right to withdraw was protected, and (6) any additional safeguards for sensitive topics. It belongs in your methodology chapter, typically after your data collection section.

What Is a Research Ethics Statement?

A research ethics statement is a formal declaration, written in your dissertation’s methodology chapter, that documents how your research was designed and conducted in accordance with ethical principles. It is not the same as your ethics application — that is a document you submit to your institution’s ethics committee before your research begins. The ethics statement in your dissertation is the published record that summarises what was approved and how you implemented it.

It is grounded in widely accepted research ethics frameworks, most notably the Belmont Report (1979) principles of respect for persons (autonomy and informed consent), beneficence (maximising benefits and minimising harms), and justice (fair distribution of research burdens and benefits). In European research contexts, the Declaration of Helsinki is the foundational framework for human subjects research. UK institutions operate under the UK Policy Framework for Health and Social Care Research and their own institutional research governance policies.

Why It Matters — and What Happens Without Ethics Approval

Starting data collection without ethics approval is one of the most serious violations a dissertation student can commit. It is not merely a procedural box-ticking exercise — it reflects whether your research genuinely protected the people who trusted you with their time, views, and sometimes sensitive personal information.

Consequences of conducting research without ethics approval include:

  • Your institution may require you to destroy all data collected without approval — making your dissertation uncompletable
  • Disciplinary action that can affect your academic record or result in exclusion
  • Delayed graduation while the situation is investigated
  • If published, a paper based on unapproved research may be retracted by the journal

Ethics applications typically take 2–6 weeks to process at UK universities. Build this into your timeline from the start — ideally submitting during your literature review phase so approval is confirmed before you need to begin recruiting participants.

Step 1: Obtain Ethics Approval Before Data Collection

Your ethics statement will name the body that reviewed and approved your research. This is typically:

  • UK universities: A departmental or faculty Research Ethics Committee (REC), sometimes called the Ethics Review Board or Committee
  • US universities: The Institutional Review Board (IRB)
  • Health and clinical research: NHS Health Research Authority (HRA) in the UK; an IRB or equivalent in other countries
  • EU-funded research: Ethics review required under Horizon Europe rules

Your ethics approval letter or email will include a reference number (sometimes called an approval number or protocol number). Record this number and use it verbatim in your methodology chapter.

If your research is deemed low risk by your institution (e.g., secondary data analysis of publicly available data with no human participants, or observation of non-sensitive public behaviour), you may receive a formal low-risk exemption rather than full committee review. The exemption still needs to be documented in your ethics statement — it does not mean ethics do not apply.

Informed consent means that participants agreed to take part in your research after being given sufficient, accurate information about what participation involves, presented in a way they could understand. Your ethics statement should specify:

  • What information was provided: Confirm that a Participant Information Sheet (PIS) was given to all participants before the study began. The PIS should explain the study purpose, what participation involves, the right to withdraw, how data will be used, and contact details.
  • How consent was recorded: Written consent form (signed), digital consent (electronic signature, checkbox with timestamp), verbal consent (audio recorded, documented in field notes), or waived consent (for purely observational or anonymous survey research — must be explicitly approved by the ethics committee)
  • Who consented: If research involved minors (under 18), you need parental/guardian consent in addition to the child’s assent
  • When consent was obtained: Always before data collection began — never retrospectively

Step 3: Explain Your Anonymisation and Confidentiality Measures

Anonymity and confidentiality are related but distinct:

  • Anonymity: You do not know the identity of participants — their responses are completely untied from their identity. Possible in online surveys with no IP tracking; impossible in face-to-face interviews where you know who you spoke to.
  • Confidentiality: You know who participants are, but you protect their identity in all outputs — no names, pseudonyms used instead, details changed or aggregated where necessary

In your ethics statement, specify which applies to your study and describe how you implemented it:

  • Names replaced with pseudonyms or participant codes (P1, P2…) at the transcription/data entry stage
  • Identifying details (job titles, specific geographic locations, unusual characteristics) altered or removed in quotes used in the dissertation
  • For surveys: whether IP addresses were logged or suppressed; whether the survey platform linked responses to email addresses
  • Any exceptions where full anonymity is not possible (e.g., a study of a single named organisation) and how you managed this with participants

Step 4: Describe Your Data Storage and Retention Plan

GDPR (in the UK and EU) and equivalent data protection legislation in other jurisdictions impose strict requirements on how personal data from research participants is stored and retained. Your ethics statement must explain:

  • Where data is stored: University-approved encrypted cloud storage (OneDrive for Business, SharePoint, or your institution’s research data repository — not personal Google Drive or Dropbox)
  • Who has access: Typically you and your supervisor only
  • How long data is retained: Most institutions require research data to be retained for a minimum of 10 years post-publication or thesis submission; underlying data for clinical research 20+ years. Check your institutional policy.
  • What happens at the end of the retention period: Secure deletion (for personal data); de-identified data may be retained longer or deposited in an open archive
  • Audio recordings: These are typically deleted after transcription and verification, as they carry the highest re-identification risk

Step 5: Confirm the Right to Withdraw

Participants must be informed — and your ethics statement must confirm — that they can withdraw from the study at any time without providing a reason and without penalty. For interview-based studies, this right typically extends to a specified point after the interview (e.g., “participants were informed that they could withdraw their data up to two weeks after their interview”). After data is anonymised and analysed, withdrawal is usually no longer possible, and this cut-off point should be stated clearly in your Participant Information Sheet and echoed in your ethics statement.

Step 6: Address Additional Safeguards for Sensitive Research

If your research touches on sensitive topics — mental health, trauma, substance use, criminal behaviour, sexuality, immigration status, political views in contexts of risk — your ethics statement needs to go further. Describe:

  • Specific risk assessment conducted for distress or harm to participants
  • Signposting plan: how participants were directed to support services if the research raised distressing issues (provide the actual signposting text you used — e.g., “If participants showed signs of distress, the interview was paused and they were provided with contact information for [relevant service]”)
  • Whether a vulnerable population was involved and what additional safeguards applied
  • Whether a debrief was provided after data collection and what it contained

Copy-Paste Ethics Statement Templates

Adapt these templates to your specific study. Replace bracketed text with your actual details.

Template 1: Interview-Based Study (UK University)

“This study received ethical approval from the [School/Faculty] Research Ethics Committee at [University Name] on [Date] (Reference: [REC/XXXX/XX]). All participants were provided with a Participant Information Sheet prior to the study and gave written informed consent. Participants were informed of their right to withdraw at any time without penalty, and were advised that their data could be withdrawn within [two weeks] of the interview. Participant identities were protected through the use of pseudonyms throughout transcription and all written outputs. Audio recordings were deleted following transcription verification. Data was stored on the University’s encrypted research storage systems and will be retained for [10] years in accordance with [University Name]’s Research Data Management Policy.”

Template 2: Online Survey Study

“Ethical approval for this study was granted by the [School/Faculty] Research Ethics Committee at [University Name] (Reference: [REC/XXXX/XX]). Participation was voluntary and anonymous; the survey did not collect any personally identifiable information, and IP addresses were not logged. All participants provided informed consent by reading a study information statement on the survey’s opening page and actively checking a consent checkbox before proceeding. Participants were informed they could exit the survey at any point; however, as responses were anonymous, withdrawal of completed submissions was not possible. Data was stored on [Qualtrics/Jisc Online Surveys] in accordance with [University Name]’s data protection requirements and will be retained for [10] years.”

Template 3: Secondary Data / Low-Risk Exemption

“This study used secondary data from [Dataset Name / Source], which is publicly available under [licence/open access terms]. As the research involved no primary data collection from human participants, it was classified as low risk and received a formal exemption from full ethics committee review by the [School/Faculty] Research Ethics Committee at [University Name] on [Date] (Reference: [EXEMPT/XXXX/XX]). Data handling complied with [University Name]’s Research Data Management Policy.”

Writing an Ethics Statement for Low-Risk or Secondary Data Research

Not all dissertations involve primary data collection from human participants. If your study uses:

  • Publicly available datasets (Office for National Statistics, UKDA, World Bank, etc.)
  • Previously published text (court documents, news archives, published reports)
  • Observation of public, non-sensitive behaviour in genuinely public spaces

…you may qualify for a low-risk exemption or a streamlined ethics review. However, “low risk” must be formally determined by your institution’s ethics committee — you cannot self-assess. In your ethics statement, confirm that the exemption was granted, provide the reference number, and briefly explain why the research was categorised as low risk.

Even without human participants, your ethics statement should note compliance with any relevant data licences (e.g., you are not redistributing restricted data) and your institution’s research governance expectations.

Frequently Asked Questions

How long should a research ethics statement be in a dissertation?

A research ethics statement in a dissertation methodology chapter is typically 150–400 words for a standard quantitative or qualitative study. It should be concise but complete — covering ethics approval, informed consent, anonymisation, data storage, and the right to withdraw. Studies involving sensitive topics, vulnerable populations, or complex ethical issues warrant a longer treatment (400–700 words). The key is to address every required element clearly, not to pad the section with general statements about research ethics principles.

What if I forgot to get ethics approval before starting data collection?

Contact your supervisor and your institution’s ethics committee as soon as possible. Some institutions offer retrospective review in limited circumstances, though this is not guaranteed and may result in restrictions on how you can use the data. Do not submit a dissertation claiming ethics approval was obtained when it was not — this is research misconduct. In the worst case, you may need to redesign your data collection using ethically approved methods and start again. Early submission of ethics applications is the only reliable solution — plan to submit at least 6–8 weeks before you intend to begin recruiting.

Can I use email or a checkbox for informed consent instead of a signed form?

Yes — digital consent is widely accepted at UK and US universities for most non-clinical research. An electronic checkbox that participants must actively select (not pre-ticked) on an online survey, or an email reply confirming consent after receiving a Participant Information Sheet, constitutes valid informed consent in most institutional frameworks. For clinical research, or studies involving particularly vulnerable populations, your ethics committee may require a wet ink or qualified electronic signature. Check your institution’s specific requirements when designing your consent process.

What is the difference between anonymity and confidentiality?

Anonymity means you genuinely do not know who your participants are — their identity is never linked to their data. This is possible in fully anonymous surveys where no identifiers are collected. Confidentiality means you know who your participants are, but you protect their identity in all published outputs by using pseudonyms, removing identifying details, or aggregating data. Most interview-based research provides confidentiality rather than anonymity because you meet participants directly. In your ethics statement, use the correct term for your study — claiming anonymity when you conducted named interviews is inaccurate and potentially misleading.

Do I need ethics approval for a literature review dissertation?

A pure literature review or systematic review that analyses only published, publicly available research does not typically require ethics approval for human participants — since no primary data is collected from people. However, you should still check with your institution, as some require a formal low-risk exemption even for secondary research. Your methodology chapter should state that no primary data collection from human participants occurred, and that ethical considerations are limited to accurate citation and honest representation of source material. If your review involves any analysis of unpublished data or direct contact with authors, different rules may apply.
