Goal 1: To utilize recent technological advances and refine a theory-based, computerized intervention system currently being evaluated in a Birmingham STD clinic. Our proposed interventions will target men-who-have-sex-with-men (MSM) and will be designed to: increase condom use for specific sexual activities with both main and casual (other) partners; decrease numbers of sexual partners among those reporting multiple partners; and increase the frequency of HIV serostatus disclosure to sexual partners.
