Questions to Ask Before Joining a Research Study

Choosing whether to join a clinical trial is a personal decision. There is no universal right answer — only the answer that fits your health, your life, and your comfort level. Bringing a written list of questions to your screening visit can help you make that decision from a place of confidence rather than uncertainty.

About the study itself

• What is the purpose of this study, and what question is it trying to answer?
• What phase is the study in, and what has already been learned about the treatment?
• How long will the study last, and how many visits will be required?
• Who is sponsoring the research, and who has reviewed the protocol?

About what you will experience

• What procedures will I go through, and which are considered experimental?
• What are the possible side effects or risks?
• What are the potential benefits — to me and to future patients?
• Will I be able to continue my current medications?
• Is there any chance I will receive a placebo, and will I know if I do?

About your rights and protections

• What happens if I experience an unexpected reaction or side effect?
• Who covers the cost of study-related care?
• How is my personal and medical information protected?
• Can I leave the study at any time, and how do I do that?

About logistics and compensation

• Where will study visits take place, and how long will each one take?
• Will I be compensated for my time and travel?
• Who do I contact between visits if I have questions or concerns?
• What happens after the study ends?

Trust your instincts

If any answer feels unclear, ask a follow-up. If the pace feels rushed, request more time. A study team that respects you will always welcome careful questions — and giving yourself space to think is one of the best signs that you are entering the process on your own terms.
