Phase 2. We hypothesize that in opioid dependent patients receiving office-based BUP, Enhanced Sexual Risk Management (ESRM) will be more effective in increasing specific safe sex practices compared with standard physician counseling, Standard Sexual Risk Management (SSRM) and that it will demonstrate cost-effectiveness overall when compared to SSRM. The specific aims of this randomized clinical trial are 1) to determine the efficacy of ESRM compared to SSRM, in individuals enrolled in BUP treatment and 2) To compare the cost-effectiveness of ESRM versus SSRM in individuals enrolled in BUP treatment. These interventions will be adapted from existing effective interventions evaluated in two recently conducted multi-site randomized clinical trials, the CDC-funded Project RESPECT and the NIMH-funded Project Light.20, 21
