Official title
Encouraging Opioid Abstinence Behavior: Incentivizing Inputs and Outcomes - Pilot
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to address two key questions in the literature on incentives for substance use. The first question is whether it is more effective to directly incentivize the outcome of interest - drug abstinence - or to incentivize behaviors that are inputs into the production of abstinence. This study will compare two versions of the incentive program: one that incentivizes inputs to achieving abstinence and one that incentivizes the outcome of abstinence. The second question is how to optimize the size of incentives over time to maximize incentive effectiveness. This will be done by randomly varying the size and timing of incentives offered to participants in both the Inputs and Outcomes groups. The incentive amounts will then be varied across participants and time to fit a structural model of abstinence behaviors over time. The model will be used to describe the optimal shape of incentives over time.
