Official title

A Randomized Clinical Trial of the Efficacy of a Behavioral Intervention to Prevent Acquisition of HIV Among Men Who Have Sex With Men

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to see if a behavioral intervention, a special kind of counseling, can reduce the risk of HIV infection in men who have sex with men. The behavioral intervention will be compared to the standard risk reduction counseling that is given before and after getting an HIV test. In standard pre- and post-test counseling, everyone is told the same things about how to prevent HIV. The behavioral intervention used in this study is designed to help each individual prevent HIV according to his specific problems and needs.
