Subject: Payments to Research Participants Definitions: 1. Third-party: Any person or vendor (external to the University) who receives payment for providing research-related services and/or products. 2. Research Payments: Cash and non-cash payments for reimbursement of time and expenses associated with participation in research activities. Policy: It is the policy of the Vanderbilt University (VU) Institutional Review Board (IRB) to review and approve payments to human research participants. I. The IRB must determine that the risks to research participants are reasonable in relation to the anticipated benefits and that the informed consent document contains an adequate description of the study procedures as well as the risks and benefits. Payment to research participants in studies is not considered a benefit. Rather, it should be considered compensation for time and inconvenience or a recruitment incentive. The amount and schedule of all payments should be presented to the IRB at the time of initial review. The IRB should review both the amount of payment and the proposed method and timing of disbursement to assure that neither are coercive nor present undue influence.
