title: Contingency management among homeless, out-of-treatment men who have sex with men.
abstract: Homeless men who have sex with men are a particularly vulnerable population with high rates of substance dependence, psychiatric disorders, and HIV prevalence. Most need strong incentives to engage with community-based prevention and treatment programs. Contingency management (CM) was implemented in a community HIV prevention setting and targeted reduced substance use and increased health-promoting behaviors over a 24-week intervention period. Participants in the CM condition achieved greater reductions in stimulant and alcohol use (χ(2) = 27.36, p < .01) and, in particular, methamphetamine use (χ(2) = 21.78, p < .01) and greater increases in health-promoting behaviors (χ(2) = 37.83, p < .01) during the intervention period than those in the control group. Reductions in substance use were maintained to 9- and 12-month follow-up evaluations. Findings indicate the utility of CM for this high-risk population and the feasibility of implementing the intervention in a community-based HIV prevention program.
