Gay, bisexual and other men who have sex with men (MSM) are the group at highest risk of HIV infection in the United States. Pre-exposure prophylaxis (PrEP) has demonstrated high efficacy in preventing HIV infection among MSM. However, uptake in clinical settings has been slow for several reasons, including low awareness and education, low perceived HIV risk, concern for side-effects, and stigma associated with taking the medication. The purpose of the proposed study is to develop and evaluate a brief motivational interviewing (MI) intervention to promote PrEP uptake among MSM during the course of routine HIV screening at a public sexually transmitted disease (STD) clinic.
