What is a Participant Retention Program?
A participant retention program is a program that involves the provision of gifts or other incentives to enrolled participants to encourage their continued participation in a study. As an example, an investigator might offer $20 gift cards to participants who reach a particular study visit milestone. Or, a sponsor might provide inexpensive gifts (e.g., tote bags, pens, t-shirts, mugs, etc.) throughout a study. All participant retention materials must be submitted for review.
