Voucher-Based Incentives in a Prevention Setting
In Brief
A Phase 3 clinical trial evaluating Voucher-Based Reinforcement Therapy for Substance-related Disorders. Completed, enrolled 131 participants across 1 site.
Detailed Summary
This study evaluates a contingency management program that rewards homeless, non-treatment-seeking substance abusing men who have sex with men (MSM) for abstaining from drugs and for performing prosocial behaviors. If this program motivates these individuals to increase prosocial and healthy behaviors and decrease drug/alcohol use, established prevention programs may modify their approaches to include contingency management, and use it to address the staggering public health problems homeless substance-abusing MSMs face on a daily basis.

Interventions
Participants were randomized into either the CM or control condition. Both conditions earned points for attendance and participation (max 364 points). Participants in the CM condition also earned points for targeted health-promoting behaviors and for drug/alcohol abstinence. CM points for targeted health-promoting behaviors were not limited. Points for abstaining from substance use were awarded based on a Level 1 (recent abstinence for amphetamine, methamphetamine, PCP, and cocaine metabolites, as well as blood alcohol \<0.05) urine sample.
