Interrogate the purpose.
Map the procedures.
Pressure-test safety.
Ask about known side effects, discomforts, uncertain risks, medication interactions, reproductive precautions, and how new information will be communicated. Learn who responds to urgent concerns and what care may be available for a study-related problem.
Audit the practical impact.
Count transportation, parking, time away from work, caregiving, meals, lodging, technology, and between-visit responsibilities. Ask about remote options, scheduling flexibility, compensation, and reimbursement. Confirm which costs the study covers and which may be billed to you or insurance.
Track your information.
Ask who can see research records, whether information or samples are coded, how long they may be stored, whether future research is planned, and what choices the consent process provides. Request clarification when the privacy language is difficult to understand.
Know the exit plan before entering.
Run the final test.
Do you understand the purpose? Can you explain the main risks and responsibilities in your own words? Does the schedule work? Have your questions been answered without pressure? If not, ask for more information or more time. “Not yet” and “no” remain valid answers.
