Questions to ask before enrolling

The screening visit is the natural moment to ask everything you want to know. Research coordinators expect questions, and a good site would rather spend an extra twenty minutes than enroll someone who is unsure. Writing your questions down beforehand helps, because it is easy to forget them in the room.

Start with the shape of the commitment. How many visits are there in total? How long is each one, and over what period? Are any visits overnight? Which parts can be rescheduled, and how much notice does the site need?

Then ask about the study itself. What question is this research trying to answer? What will happen at each visit? What are the known risks and side effects, and how are they monitored? Is there any chance of receiving a placebo, and if so, will you be told which group you were in afterwards?

Cover the practical side too. How is compensation for time and travel handled, and on what schedule? Who do you call outside office hours if something comes up? What happens to your data if you withdraw partway through?

Finally, ask what happens at the end. Will results be shared with participants? Is there any follow-up after the last visit? A site that answers these clearly is giving you what you need to make your own decision — which is exactly the point.
