The IRB is responsible for ensuring that any payment or remuneration offered to participants in human subject research is fair and not an undue inducement to participate. Remuneration for participation in research should be reasonable and the amount paid should be comparable to other research projects involving similar time, effort, and inconvenience. Payment amounts should not be large enough to constitute an undue inducement to participate in a risky or uncomfortable procedure. Additional guidelines for specific situations:

• Short research studies involving one visit: Participants may be provided payment contingent upon completion of the study. Participants who are disqualified through no fault of their own must be paid for the time and effort they expended prior to their termination from the study.
• Research studies involving multiple visits or lengthy or repeated participation: Partial payment should be provided to participants who withdraw, are discharged early from the study by the investigator, or otherwise fail to complete the study as agreed. The amount of partial payment should relate to the amount of time, effort, or discomfort involved. Payment schedules may be designed on a per-day, per-visit, or per-procedure rate, or some combination thereof. The terms for partial payment must be described in the application and in the consent form.
• Completion bonuses: Such remuneration may be acceptable to encourage the completion of all study procedures/visits. The amount of such incentives depends on the risk and duration of the study interventions.
• Lottery incentives: Research teams that wish to employ recruitment incentives in which research participants are entered into a drawing to win a prize should consult with the UW Office of Legal Affairs.
