If the study involves a medication, ask whether it is already approved, experimental, or being tested for a new use. Check possible side effects, interactions with current treatment, dose changes, monitoring, and what happens if you feel worse. For any mental health study, also ask who to contact if you feel worse, whether participation may affect current treatment, whether you can stop, and who confirms eligibility.

The listed study locations suggest that at least part of participation may involve a physical site. Ask which sites are open, how many visits are expected, whether any steps can be done remotely, and whether travel costs or compensation are listed.
