GPS: Adaptation Trial of an HIV Prevention Counselling Program for HIV-positive and HIV-negative Gay and Bisexual Men

GPS is a sexual health promotion and HIV prevention program. It has 4 components: provision of information on HIV and sexually transmitted infections, motivational interviewing counselling, sexual health behavioural skills building, and linkage to care in the local community (e.g., referrals to medical, social service, social, mental health, and substance use programs). Among HIV-positive men who have sex with men (MSM) GPS is associated with positive health outcomes including decreased likelihood of condomless anal sex (CAS), particularly CAS with serodiscordant partners. GPS is also associated with decreased fear of being rejected for insisting on condom use and increased condom use self-efficacy.
