Know the time commitment, payment schedule, and possible expenses before deciding.
Some studies offer compensation for time and participation or reimburse specified expenses. Amounts and arrangements differ by study. Payment is not a medical benefit and does not mean that a study is right for you.
Ask for the details
- Which visits or activities are paid, and when?
- Is screening compensated if I am not eligible?
- Which travel or other expenses are reimbursed, and are receipts required?
- What payment will I receive if I stop early?
- Are there any completion payments, limits, or payment-related reporting requirements?
Payment for completed participation should accrue as the study progresses and should not depend on completing the whole trial. The IRB-reviewed study documents describe the applicable schedule. Ask the team to explain any unclear terms before consenting.
Consider the whole commitment
Compare the expected travel, visits, procedures, and possible risks with your circumstances. You do not have to join a study to ask about it. Participation may help answer research questions, but personal benefit is not guaranteed.
