Several challenges have emerged in ensuring uptake of preexposure prophylaxis (PrEP) for HIV prevention. By applying the health belief model, the present study assessed associations between novel psychosocial variables and PrEP use among gay and bisexual men. Logistic regression analyses indicated that heterosexual self-presentation, sexual risk, PrEP conspiracy beliefs, and perceived peer PrEP use were positively associated with PrEP use. Greater understanding of the psychosocial barriers to PrEP use for unique at-risk populations can facilitate the development of socially informed prevention strategies.
