 This study will test the efficacy of the Being Responsible for Ourselves BRO HIV Risk Reduction Intervention in increasing condom use and reducing other sexual risk behaviors among African American MSM in Philadelphia, where African Americans account for 70 of the reported cases of AIDS through June 2005. The study will use a RCT design, which is the most scientifically sound method for assessing the causal impact of interventions. An attention-matched control group, the Health Promotion Intervention, will provide controls for Hawthorne effects and special attention. Computer-generated random number sequences will be used to randomly assign participants to the intervention arms using concealment of allocation techniques designed to minimize bias in assignment. The biostatistician will generate the random assignments; the project director will implement the assignments. The study will also examine theoretical variables the intervention is designed to affect, which will permit mediation analyses addressing why the intervention is efficacious or not efficacious. This study, then, will provide an urgently needed intervention to help curb the alarmingly high incidence of HIV in urban, African American communities.
