The present study will provide pilot data for a novel and innovative HIV prevention intervention for MSM. This intervention will build upon empirically supported interventions to reduce HIV risk among MSM and cognitive-behavioural therapy to reduce social anxiety. This pilot study will serve 3 related major objectives: 1) to provide data on the acceptability and feasibility of the intervention administered, 2) to provide pilot data testing the intervention, and 3) to provide data that will allow Dr. Hart and his team to apply to CIHR for a Phase II trial that will test the efficacy of the intervention relative to HIV prevention interventions that do not reduce social anxiety or substance use in sexual situations among MSM.
