Should Researchers Work Alone With Participants in Private or Potentially Unsafe Settings?

Working alone with a participant is not automatically unsafe or unethical. The decision should depend on the participant, setting, activity, researcher, available safeguards, and consequences if something goes wrong.

Should Researchers Work Alone With Participants? Guide 420 of 530
01 · The Question

Is It Safe or Ethical to Meet a Research Participant Alone?

Qualitative research often depends on privacy. A participant discussing domestic violence, health, sexuality, workplace misconduct, political beliefs, or another sensitive experience may not speak freely with additional people in the room. Ethnographic and community research may also take researchers into homes and other places where bringing a colleague would be intrusive or impractical.

Yet privacy can create a safety problem. If a researcher is alone with a participant in a private home, isolated room, unfamiliar neighborhood, vehicle, or remote location, assistance may not be immediately available if the situation changes.

So should researchers avoid one-to-one meetings altogether? Usually, the better question is whether lone working is appropriate under the particular conditions and what safeguards would make the remaining risk acceptable.

02 · The Short Answer

Lone Research Is Not Automatically Prohibited, but It Should Be Assessed

In Brief

Researchers can sometimes work alone with participants, including in private settings, but they should not do so automatically when the circumstances create foreseeable safety risks that have not been adequately assessed and managed.

There is no universal rule that every one-to-one interview requires a second researcher. The appropriate arrangement depends on the location, participant interaction, research topic, researcher circumstances, available communication and exit options, and institutional requirements.

03 · What You Need to Know

The Question Is Not Simply Whether You Are Alone

Lone working changes what happens if something goes wrong

Being alone is not itself evidence that an activity is unsafe. It does, however, remove some forms of immediate assistance. A colleague cannot intervene, call for help, witness an incident, or notice that the researcher has failed to return if no system has been established for doing so.

This is why lone fieldwork appears explicitly in research-safety guidance. UKRI's Economic and Social Research Council states that research ethics committees should consider researcher safety, especially in circumstances including lone fieldwork. UCL's off-site working guidance similarly identifies lone or isolated working as a significant consideration during research home visits and requires assessment of whether lone working is appropriate or a colleague should be present.

The existence of lone working should therefore trigger a question, not an automatic conclusion.

A private setting and an unsafe setting are not the same thing

Privacy can be ethically valuable. Sensitive interviews may require a setting where participants cannot be overheard. Confidentiality, autonomy, and the quality of disclosure may all be affected if family members, employers, gatekeepers, or other people remain present.

That does not mean every private setting is equally appropriate. A bookable interview room with nearby staff and two exits creates a different risk profile from an isolated private residence that the researcher has never visited. Likewise, a participant's request for privacy does not necessarily require the researcher to accept whatever location the participant proposes.

Privacy Protects the participant's ability to communicate without unnecessary observation, interruption, or disclosure to others.
Isolation May reduce the researcher's access to assistance, communication, witnesses, or a safe exit if circumstances deteriorate.

Good planning tries to preserve necessary privacy without creating unnecessary isolation.

Home interviews require their own risk assessment

Participant homes are common and sometimes highly appropriate research settings. They may be more accessible, comfortable, or private for participants who cannot easily travel. But the researcher has less control over the environment.

UCL's off-site working guidance identifies several potential hazards associated with home visits, including physical assault or verbal abuse, theft or damage to property, animals, and lone or isolated working. These examples illustrate why “the participant's home” should not be treated as a neutral location merely because the participant prefers it.

Before a home visit, relevant questions may include who else is likely to be present, whether the location can be reached and left safely, whether reliable communication is available, what time the visit will occur, whether there are known hazards, and whether the researcher has a practical exit strategy.

The participant's characteristics should not become a shortcut for labeling someone dangerous

Safety assessment needs care because crude assumptions can stigmatize participants. Membership in a vulnerable population, having a mental health condition, having a criminal history, experiencing homelessness, or discussing a sensitive topic does not by itself establish that a participant poses a threat.

The assessment should instead focus on credible hazards arising from the interaction and context. Relevant information may include known previous threatening behavior where legitimately available, the nature of the proposed activity, environmental conditions, prior contact, safeguarding concerns, and whether the research design creates predictable conflict.

Risk assessment should protect researchers without converting stereotypes into safety policy.

The researcher's circumstances also matter

A location that is manageable for one researcher may present different risks for another. Familiarity with the area, experience conducting difficult interviews, communication ability, accessibility requirements, mobility, transportation, and other circumstances can affect both exposure and the researcher's options if something happens.

UKRI's current grant guidance requires research organizations to conduct suitable and sufficient risk assessment for on-site and off-site research and, where appropriate, consider reasonable adjustments for individual circumstances.

This does not mean researchers should be excluded from fieldwork because of personal characteristics. Rather, safety arrangements should fit the person actually doing the work.

Check-in systems are useful only if someone will act on them

A common safeguard for lone fieldwork is a check-in or buddy system. The researcher provides details of where they will be, confirms arrival or departure, and contacts a designated person at agreed times.

That system needs an escalation procedure. Who notices a missed check-in? How long do they wait? Do they call the researcher, the venue, a supervisor, security personnel, or emergency services? What information do they have about the researcher's location?

UCL's lone-working guidance includes periodic checks and confirmation of start and finish among possible controls for interviewing participants in homes or isolated locations. The important principle is that a check-in is a safety mechanism only when a missed check-in causes an appropriate response.

Researchers need a realistic way to leave

A researcher should not enter a potentially difficult meeting without considering how it can end. This may involve sitting where the exit remains accessible, maintaining independent transportation, avoiding locations from which departure depends entirely on the participant, keeping communication available, or arranging a predetermined reason to make contact with a colleague.

Researchers should also know that they are permitted to end an interview or field visit when they feel unsafe. A protocol that describes how to enter the field but not how to leave it is incomplete.

Adding another researcher is one control, not the universal solution

Pairing researchers can reduce some risks, but it has costs and may introduce new ethical issues. A second researcher may make a participant less willing to disclose sensitive information, increase perceived formality, create confidentiality concerns, or simply be impractical for large projects.

Other controls may sometimes achieve the necessary level of safety: choosing a different venue, meeting during daylight hours, establishing check-ins, arranging nearby support, using remote interviewing, changing transportation arrangements, or modifying the data-collection procedure.

The aim is not to maximize the number of people present. It is to reduce foreseeable risk without unnecessarily compromising the research or the participant's privacy.

Some situations may make lone working inappropriate

There are circumstances in which the remaining risk may be too high to justify lone working. This could occur where there is credible information about serious aggression, where the location presents substantial hazards, where reliable communication or emergency assistance is unavailable, or where institutional policy prohibits the arrangement.

The appropriate response may be to use two researchers, relocate the encounter, use another mode of data collection, involve appropriate local support, postpone the activity, or decide that the proposed interaction should not proceed.

Exactly who has authority to assess and manage researcher safety should be established under the institution's procedures rather than left to the researcher to negotiate alone.

04 · A Practical Example

When a Participant Requests an Interview at Home

Hypothetical Example

A confidential evening interview

A researcher is interviewing adults about workplace discrimination. One participant cannot attend during working hours and asks the researcher to come to their home at 8:30 p.m. The researcher would be traveling alone to an unfamiliar area.

Identify the need The participant has a legitimate reason for requesting privacy and an evening appointment. The request itself is not evidence that the participant is unsafe.
Assess the arrangement The team considers travel, location, timing, communication, who else may be present, the researcher's ability to leave independently, and the institution's lone-working requirements.
Consider alternatives The researcher offers a private room at an accessible neutral venue, a secure remote interview, or an earlier home visit. If a home visit remains appropriate, additional controls are considered.
Establish safeguards The researcher's itinerary is recorded under the approved procedure, check-in and escalation times are agreed, independent transport is maintained, and the researcher knows that the visit can be terminated if circumstances become unsafe.
Reassess on arrival If the actual situation differs materially from what was expected, the researcher does not have to proceed merely because the interview was scheduled.

The decision is therefore not “home interviews are safe” or “researchers must never enter participants' homes.” It is whether this particular interaction can be conducted with an acceptable level of risk under the applicable institutional procedures.

05 · What Researchers Often Get Wrong

Common Mistakes About Lone and Private Research Encounters

Misconception

Researchers Should Never Be Alone With Participants

There is no universal research-ethics rule prohibiting one-to-one data collection. Private interviews are routine and can be ethically important. The relevant question is whether foreseeable risks have been assessed and appropriately controlled.

Misconception

If the Participant Chooses the Location, the Researcher Should Accept It

Participant convenience and preference matter, but they do not override researcher safety. Researchers can negotiate another location or mode of participation when the proposed arrangement creates unacceptable or inadequately controlled risk.

Misconception

A Private Interview Must Take Place Somewhere Isolated

Privacy and isolation are different. A room can protect confidentiality while remaining near colleagues, security, reception staff, or other sources of assistance. The safest appropriate setting may preserve both privacy and access to support.

Misconception

A Check-In Message Is Enough to Manage Lone Working

A check-in system needs someone to receive it and a predetermined response when it does not arrive. Otherwise, it records the researcher's absence without actually managing the consequences.

Misconception

An Approved Interview Must Go Ahead Once the Researcher Arrives

Approval is based on anticipated conditions. If the actual setting presents materially different or unacceptable risks, the researcher may need to postpone, relocate, modify, or end the activity according to the project's safety and institutional procedures.

06 · What This Means for You

Decide Whether Lone Working Is Appropriate Before the Meeting

Do not reduce the decision to “Am I comfortable going alone?” Personal judgment matters, particularly when conditions change, but a defensible safety decision should consider the foreseeable risks created by the fieldwork arrangement and the controls available.

A simple decision framework

If the setting is private but controlled and credible risks are low
One-to-one data collection may be appropriate under normal institutional procedures.
If lone working introduces manageable risks
Use proportionate controls such as safer scheduling, check-ins, independent transport, communication arrangements, or a more suitable venue.
If risk remains substantial despite reasonable controls
Do not default to lone working. Consider a second researcher, another location or mode, postponement, or another method consistent with the research purpose.
If conditions become unsafe during the encounter
Follow the safety and exit procedure rather than continuing simply because the interview has begun.

The final arrangement should satisfy both ethical and institutional requirements. Researcher safety is not achieved by eliminating every private interaction, but neither should privacy become an excuse for avoidable exposure.

07 · A Quick Checklist

Before Meeting a Participant Alone, What Should You Check?

Before a lone or private research encounter, check:
Verify your institution's requirements for lone working, off-site research, home visits, travel, and fieldwork.
Assess the actual location, time, travel arrangements, communication access, and availability of assistance.
Consider credible information about the interaction without treating participant characteristics or vulnerability as automatic evidence of dangerousness.
Determine whether the necessary privacy can be achieved in a safer or less isolated setting.
Establish check-in and check-out procedures and specify what happens if contact is missed.
Maintain a realistic way to leave the setting and obtain assistance if conditions change.
Know who has authority to require paired working, relocate the meeting, postpone it, or approve another arrangement.
Make sure the researcher knows they can follow the project's procedure for ending the encounter if immediate safety deteriorates.
08 · Frequently Asked Questions

Frequently Asked Questions About Working Alone With Participants

Is it unethical to interview a participant alone?

No. One-to-one interviews are common and may be necessary for privacy and confidentiality. Ethical acceptability depends on the context, foreseeable risks, safeguards, and applicable institutional requirements rather than the number of researchers present alone.

Can a researcher interview someone in their home?

Potentially, yes. Home interviews can be appropriate, but the location should be included in the fieldwork and safety assessment. Relevant issues may include lone working, travel, other people or animals in the home, communication, and the researcher's ability to leave safely.

Should two researchers always attend interviews with potentially vulnerable participants?

No universal rule requires this. Participant vulnerability should not automatically be equated with danger to researchers. Decisions about paired working should be based on credible risks, research needs, participant privacy, and institutional requirements.

What should a lone-worker check-in system include?

It should specify who knows the researcher's location and schedule, when contact is expected, what counts as a missed check-in, who responds, what steps they take, and when further assistance or emergency action is appropriate.

Can the researcher change the interview location for safety reasons?

Usually this should be possible where consistent with the approved protocol and institutional procedures. If the change is substantial or affects participant privacy, consent, accessibility, or approved methodology, additional approval or consultation may be required.

What if the researcher only realizes the location is unsafe after arriving?

The researcher should follow the project's safety procedure and exercise appropriate judgment rather than assuming that arrival creates an obligation to proceed. Material changes in risk should subsequently be reported and reassessed under the applicable institutional process.

09 · The Bottom Line

Privacy Does Not Have to Mean Unmanaged Isolation

The Bottom Line

Researchers may work alone with participants when the arrangement is appropriate, but private or potentially unsafe settings require a proportionate assessment of the location, interaction, researcher, available support, and consequences if something goes wrong.

The goal is not to prohibit private research encounters. It is to preserve necessary privacy while avoiding unnecessary isolation and ensuring that researchers have workable communication, support, exit, and escalation arrangements when the context warrants them.
