Specific Aim 1. Conduct 18 focus groups among Black gay, bisexual and other sexual minority men (SMM; n=72-90) in the Washington, DC area of different age groups (18-24, 25-34, 35+) and various pre-exposure prophylaxis (PrEP) use profiles (i.e., PrEP naïve, current PrEP users, and discontinued PrEP; two per age-group and PrEP use profile) to understand intervention feasibility, acceptability and appropriateness, how the intervention can address experienced and perceived socio-structural barriers, and increase PrEP initiation and adherence among Black SMM in the Washington, District of Columbia (DC) area. Specific Aim 2. Implement an iterative open-phase pilot of an SNS intervention to increase PrEP initiation among human immunodeficiency virus (HIV)-negative Black SMM, aged 18 years and above, in the Washington, DC area. Recruit 30 PrEP-using Black SMM, including those who use substances, as Recruiters to identify and refer Network Associates to PrEP services. The pilot will occur in six blocks of up to 5 Recruiters to further develop all intervention procedures and enhance the social networking strategy (SNS) intervention's feasibility and acceptability.
