What exactly is the study investigating?
Ask the team to describe the research question and which activities would involve you. A PTSD study might involve observation, questionnaires, interviews, therapy, medication or another approach, depending on its protocol. These are examples, not a menu available at every centre. Clarify whether the study offers an intervention or only collects information, and what remains unknown about any potential benefit. You can ask how the official registry record relates to the current participant information. A condition label on a listing does not establish that the procedures or eligibility criteria suit your situation.
Will you be asked to describe traumatic experiences?
Before sharing details, ask what information is needed, for what purpose, at which stage and with whom. Ask whether questions are written, spoken, recorded or repeated at later visits. Discuss what choices are possible if you do not want to answer a particular question and what that would mean for participation. Do not assume you must give a full account in an initial enquiry. Use the study’s verified private process for sensitive information. You can ask about the procedure without describing the experience itself in a public form or conversation.
What happens if an activity becomes overwhelming?
Ask how the team checks distress during and after the relevant activity, whether breaks or stopping a procedure are possible and what happens next. Find out who is available, at what hours and how a concern is passed to a clinician. Ask about the plan after a difficult appointment, including getting home or contacting support if relevant. Do not assume every requested accommodation can be provided; the team should explain its actual arrangements. A research portal or scheduled message service is not a substitute for urgent care when immediate help is needed.
How would the study fit your current care?
Discuss existing therapy, medicines and other health conditions through the team’s verified assessment process. Ask whether any aspect of participation would conflict with appointments, therapeutic work or other support you already receive. If a treatment requirement or change is mentioned, ask the study clinician and your usual clinician to explain risks, monitoring and alternatives. Do not change medication or pause therapy just to fit a listing. NIMH’s PTSD information notes that experiences and co-occurring conditions vary; only the responsible team can assess the protocol and your particular circumstances.
Who can see interviews, recordings and other sensitive data?
Ask whether the study uses audio, video, written narratives or app entries, and whether each is necessary or optional. Find out who sees identifiable information, who works with codes and whether material may be shared for training or future research. Do not assume that removing your name from a recording makes it anonymous. Ask for the study’s privacy notice and a contact for unresolved questions. If a supporter attends, agree separately what can be discussed in front of them. Your preferences about a sensitive conversation deserve an explicit discussion, not an assumption.
What practical support and follow-up should you confirm?
Ask about visit format, travel, time to recover from an appointment if needed and whether a chosen supporter can attend. Check how contact works between visits and after your participation ends. Ask what happens if a procedure is unsuitable or you decide to stop. You can write down three priorities for the first conversation, such as control over disclosure, the distress-support plan and coordination with your clinician. The study examples below are starting points from a catalogue, not confirmation that a specific centre is recruiting or that a procedure is suitable for you.
