How to Interview People Ethically for Research Projects

Interviewing people for a research project requires more than preparing questions and collecting answers. Researchers must consider whether participants understand the study, feel free to decline, and know how their information will be used.

For students conducting their first interviews, ethical responsibilities begin before contacting potential participants. Permission, informed consent, confidentiality, question design, and secure data handling all require attention.

An interview that appears straightforward can raise difficult questions. Can a student refuse an interview requested by their teacher? Does agreeing to participate also mean agreeing to be recorded? Can a researcher promise anonymity when they know the participant's identity?

Professional guidance from the British Educational Research Association (BERA) and the UK Economic and Social Research Council (ESRC) emphasises voluntary participation, ongoing consent, participant welfare, and responsibility throughout the research process.

Answer Summary: To interview people ethically for research projects, check applicable ethics requirements, invite participants without pressure, explain the research clearly, and obtain informed consent. During interviews, ask respectful questions, protect privacy, and allow participants to skip questions or stop. Afterward, secure recordings and transcripts, report findings fairly, and follow the agreed withdrawal and data-management procedures. Requirements vary across institutions, countries, and research contexts.

Key Takeaways:

• Check institutional ethics requirements before recruiting participants.

• Ensure participation is informed, voluntary, and free from pressure.

• Separate interview consent from recording, identification, and data-sharing permissions.

• Use neutral questions and respect participants' boundaries.

• Protect identifiable information throughout collection, analysis, and reporting.

• Explain withdrawal procedures and confidentiality limitations accurately.

What Makes a Research Interview Ethical?

An ethical research interview respects participants' autonomy, dignity, privacy, and welfare while collecting information for a legitimate research purpose.

Ethical practice involves more than good intentions or courteous behaviour. Researchers must consider the consequences of their decisions before, during, and after interviews.

The Belmont Report, published in 1979, identifies three foundational principles for research involving human participants:

• Respect for persons: Recognising individuals' autonomy and protecting those whose ability to make independent decisions is limited.

• Beneficence: Considering potential benefits and taking reasonable measures to reduce harm.

• Justice: Selecting participants fairly and considering how research burdens and benefits are distributed.

These principles provide an ethical foundation, although the Belmont Report is not a universal legal code.

For interview research, their practical meaning is straightforward: participants should understand what they are agreeing to, have meaningful freedom to choose, and receive appropriate protection when sharing information.

A signed consent form cannot compensate for coercive recruitment, unnecessary personal questions, or insecure handling of sensitive data.

Check Permission and Ethics Review Requirements

Researchers should establish the applicable ethics review process before inviting people to participate.

Requirements depend on the institution, jurisdiction, research purpose, participant population, and potential risks.

Determine whether ethics review is required

Universities and research organisations may review studies through a research ethics committee (REC), institutional review board (IRB), or departmental process.

Not every interview project requires the same level of review.

The ESRC explains that ethics review should reflect the potential risks of a study. Its guidance allows proportionate review for lower-risk research within its framework, while projects with greater potential for harm may require fuller assessment.

Students should consult their supervisor, department, or research ethics office rather than assuming that classroom assignments are automatically exempt.

Before seeking approval, prepare a clear research question, interview plan, participant information, and proposed data-management arrangements.

Related guidance on effective research project preparation explains how to organise research questions and methods.

Distinguish institutional permission from participant consent

Permission from a school, employer, organisation, or community leader does not automatically mean individuals have agreed to participate.

Such authorities may act as gatekeepers by allowing researchers to enter a setting or approach potential participants.

Individual consent remains a separate ethical consideration.

For instance, permission from a school principal to conduct interviews does not mean teachers or students are required to answer questions.

Researchers must also follow any relevant safeguarding, institutional access, and approval conditions.

Recruit Participants Without Pressure

Ethical recruitment gives potential participants a meaningful opportunity to accept or decline an invitation.

Pressure may arise when researchers hold authority over the people they approach.

A student invited by their teacher may worry that refusal could affect academic relationships. An employee approached by a manager may have similar concerns.

BERA's 2024 guidelines specifically address power relationships when teachers, lecturers, or managers research people under their authority.

Researchers should explain the voluntary nature of participation and, where accurate, confirm that declining will not affect grades, employment, services, or other relevant arrangements.

Where an authority relationship exists, independent recruitment or interviewing arrangements may help reduce pressure.

Participant selection also deserves attention. Recruiting people because they are accessible is not inherently unethical, but selection should remain appropriate to the research purpose and fair to those involved.

Any compensation or reimbursement should be disclosed appropriately. Incentives should not be so influential that they undermine an individual's freedom to decide.

Explain the Research and Obtain Informed Consent

Informed consent means participants receive understandable information and voluntarily agree to take part.

Consent should remain meaningful throughout the research, rather than being treated as a signature collected before questioning.

The ESRC's consent guidance emphasises accessible information, freedom from coercion, and opportunities to reconsider participation.

What information should participants receive?

Before an interview, researchers should explain:

1. Who is conducting the study and which institution is responsible.

2. The purpose of the research and how findings may be used.

3. What participation involves, including interview topics and expected duration.

4. Whether participation is voluntary and questions can be skipped.

5. Whether audio or video recording is proposed.

6. How recordings, transcripts, and personal information will be stored.

7. Who may access the information and whether it may be shared or reused.

8. Whether names or identifiable quotations may appear in reports.

9. The applicable confidentiality protections and their limitations.

10. How participants can withdraw and whom they can contact with concerns.

This information should be presented in language and formats participants can understand.

Participants should have sufficient time to consider their involvement and ask questions.

Separate different types of permission

Agreement to participate does not automatically authorise every subsequent use of the interview.

Researchers should distinguish consent to participate from permission to:

• Record audio or video.

• Identify participants by name.

• Publish attributable quotations.

• Share transcripts or other research data.

• Reuse information for additional research purposes.

For example, someone may agree to answer questions but refuse audio recording.

If the approved research design permits written notes instead, that alternative may be appropriate.

Where recording is essential, participants should be informed before agreeing to participate. Recording should not proceed without the required permission.

Is written consent necessary?

Written consent is common, but signatures are not universally required.

Depending on the research setting and applicable requirements, verbal consent or another documented procedure may be appropriate.

ESRC guidance recognises that alternative consent procedures can sometimes be more ethical than obtaining a signature.

Researchers must follow the method authorised by their institution or relevant review process.

Regardless of format, consent must reflect a meaningful and informed decision.

Conduct Interviews Respectfully

Ethical interview questions allow participants to express their experiences without unnecessary pressure or manipulation.

Researchers should prepare relevant questions while remaining attentive to participants' comfort and freedom to respond.

Ask clear, neutral questions

Leading questions can influence answers by introducing assumptions or preferred conclusions.

Consider this illustrative comparison:

Neutral wording allows positive, negative, or mixed responses.

Open-ended questions are useful when researchers want participants to explain experiences in their own words.

Follow-up questions such as "Can you explain that further?" or "What influenced your decision?" can provide clarification without suggesting an answer.

The Open University's course on qualitative interviewing discusses question design, ongoing consent, and respectful interview practice.

Respect silence and personal boundaries

Participants may need time to consider a question.

Researchers should avoid interpreting silence as agreement or repeatedly pressing for an answer after someone has indicated reluctance.

Questions should remain relevant to the approved research purpose. Collecting unnecessary personal details creates additional privacy responsibilities without necessarily improving the study.

Participants should be able to skip questions or request a break.

Choose an appropriate interview setting

An interview location should provide reasonable privacy, accessibility, and comfort.

For example, employees discussing workplace experiences may be less able to speak freely when supervisors can overhear.

Remote interviews require similar attention.

Researchers should consider whether other people can hear the conversation, whether the platform records automatically, and whether the participant understands the recording arrangements.

Consent should also be revisited when an interview moves into unexpectedly sensitive territory.

Protect Recordings, Transcripts, and Identities

Research information requires protection because participants' words may reveal their identities, relationships, workplaces, or personal circumstances.

Data protection should be planned before collection.

Understand privacy, confidentiality, and anonymity

These terms describe different responsibilities.

Removing a participant's name from a transcript does not necessarily make the interview anonymous.

The researcher may know the participant's identity, while recordings may contain recognisable voices.

Protect identifiable information

Appropriate safeguards may include secure institutional storage, access controls, encryption, and separate storage of identifying information.

Researchers should follow approved retention and deletion procedures rather than choosing arbitrary storage periods.

Direct identifiers include names, contact details, addresses, and identifiable institutional information.

Indirect identifiers can be equally revealing.

The UK Data Service explains that detailed personal accounts may allow identification through combinations of seemingly ordinary information, sometimes called jigsaw identification.

A quotation mentioning a rare occupation, a specific incident, and a small community may reveal a participant even after their name is removed.

Researchers should review quotations for identifying details about participants and third parties.

Consider external transcription services

Automated transcription introduces additional data-handling questions.

Before uploading recordings to an external service, check whether the provider is authorised under institutional arrangements and whether participants have been appropriately informed about the processing involved.

Researchers should understand where recordings are transferred, who may access them, and what retention or reuse conditions apply.

Permission to record an interview does not automatically authorise uploading it to an undisclosed third-party platform.

Respond When Participants Become Uncomfortable

Researchers should pause or stop questioning when continued participation conflicts with a person's expressed wishes or welfare.

Unexpected discomfort can arise even during interviews about apparently ordinary subjects.

The Open University's qualitative interviewing guidance recommends preparing for possible distress and responding with sensitivity.

If a participant becomes uncomfortable, researchers should:

1. Pause the interview and acknowledge the concern respectfully.

2. Offer the opportunity to skip the question, take a break, or stop.

3. Accept the participant's decision without demanding an explanation.

4. Follow established institutional support or safeguarding procedures where necessary.

Researchers should not pressure participants to continue because the information is valuable to the project.

Confidentiality may also have limits when serious safeguarding concerns or applicable reporting duties arise. These depend on the jurisdiction and research circumstances.

Such limitations should be explained during consent, and researchers should consult the appropriate institutional contact when uncertain.

Handle Research Information Responsibly After Interviews

Ethical responsibilities continue after the conversation ends.

Transcription, analysis, quotation selection, reporting, and future information sharing can affect participants long after data collection.

Review transcripts and report accurately

Researchers should check transcripts for errors, particularly when automated transcription was used.

Participants' statements should not be altered in ways that distort their intended meaning.

When selecting quotations, consider both accuracy and identification risk.

A quotation may be relevant to the findings but contain unnecessary details that expose someone.

Where transcript checking or quotation review has been promised or approved, researchers should provide that opportunity according to the agreed procedure.

Researchers should distinguish individual accounts from findings that can reasonably be supported by the overall study. A small interview project does not automatically establish the views of an entire population.

Explain withdrawal and data retention

Stopping participation and removing previously collected information are separate decisions.

Participants should know how to request withdrawal and what can happen to information already recorded, analysed, anonymised, or published.

The outcome depends on the research protocol, applicable law, processing stage, and whether the information remains identifiable.

For example, guidance from the United States Office for Human Research Protections explains that certain HHS-covered studies may retain and analyse information collected before withdrawal. That guidance is specific to its regulatory scope and does not establish a universal rule.

Researchers should communicate the actual withdrawal policy before consent rather than promising unrestricted deletion.

Close the interview appropriately

At the end of an interview, participants should have an opportunity to ask questions or raise concerns.

Researchers may provide an approved debriefing explanation, contact information, or details about how findings will be communicated.

Any proposed sharing or future reuse of research information must remain consistent with the consent arrangements and applicable requirements.

Situations Requiring Additional Safeguards

Some research settings involve additional ethical considerations that should be addressed before recruitment.

Interviews involving children

Research with children requires attention to age, understanding, consent, assent, safeguarding, and applicable institutional rules.

Depending on the circumstances, parental or guardian permission may be required alongside the child's own agreement or assent.

The child's willingness matters independently of an adult's permission.

UNICEF's ethics policy for its supported evidence activities emphasises children's interests, safeguarding, meaningful consent and assent, privacy, and risk management. Its requirements apply within UNICEF's stated organisational scope.

Researchers should not assume that ordinary adult interview procedures are sufficient.

Interviews involving authority relationships

Teachers researching their students and managers interviewing employees face particular challenges concerning voluntary participation.

Researchers should make their roles clear and consider whether independent recruitment or interviewing arrangements are appropriate.

Cross-cultural and multilingual interviews

Language and cultural differences can affect understanding.

Information sheets, explanations, and consent procedures should be accessible to participants.

Where interpreters are involved, their confidentiality responsibilities and role in the research should be addressed.

Permission from a community representative does not automatically replace individual consent.

Interviews involving sensitive information

Sensitive topics require careful question selection and risk assessment.

Researchers should consider whether collecting particular details is necessary and whether less intrusive questions can answer the research question.

Where safeguarding, legal, or privacy responsibilities are unclear, institutional guidance should be obtained before proceeding.

Final Ethical Interview Checklist

Before conducting a research interview, confirm the following:

• Applicable ethics review and institutional permissions have been addressed.
• Recruitment allows meaningful refusal.
• Participants understand the research purpose and procedures.
• Consent has been obtained through the approved process.
• Recording and future data-use permissions are clear.
• The interview setting offers appropriate privacy.
• Recordings and transcripts have an approved storage plan.
• Withdrawal procedures and confidentiality limits are explained.
• A response plan exists for discomfort or sensitive disclosures.
• Reporting arrangements protect participants from avoidable identification.

Unresolved safeguards should be discussed with the responsible supervisor or ethics office before data collection.

Conclusion

Ethical research interviewing depends on informed participation, respectful questioning, responsible information handling, and attention to participants' welfare.

Researchers should establish approval requirements before recruitment, explain consent and recording arrangements clearly, and preserve participants' freedom to decline or stop.

After interviews, accurate reporting and appropriate protection of identifiable information remain essential.

These practices help researchers collect useful evidence while respecting the people who contribute to their work.
