Voucher-Based Incentives in a Prevention Setting

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.
