Video Opportunities for Innovative Condom Education & Safer Sex (VOICES/VOCES) is a group-level, single-session video-based HIV/STD prevention intervention designed to increase condom negotiation skills and increase condom use among participants who visit STD clinics. Currently, CDC supports the implementation of VOICES/VOCES with men who have sex with men (MSM). Click here for more information on CDC-supported effective interventions.
