Men who have sex with men (MSM) experience high rates of substance use and HIV infection. Main partners are the source of many (35-68%) of these new HIV infections. This study developed and examined the efficacy of two adjunct components to couples HIV testing and counseling (CHTC)-communication training (CT) videos and a substance use module (SUM)-to reduce drug use and sexual HIV transmission risk in MSM couples. Participants included 70 male couples randomized into one of four conditions: CHTC, CHTC + CT videos, CHTC + SUM, and CHTC + CT videos + SUM. Participants completed a survey pre-intervention and 1-, 3-, and 6-months later. Completion of the SUM in the absence of CT videos was associated with significant immediate decreases in drug use and related problems; however, at 3- and 6-month follow ups, the SUM was only associated with reductions in drug use and related problems among men who also viewed the CT videos. There were no between-condition differences in sexual behavior. CHTC may serve as a vehicle for the delivery of brief substance use intervention for MSM couples.ClinicalTrails.gov NCT # 03125915.
