Examining Stigmatizing Beliefs about PrEP Use among Black Sexual Minority Men: A Test of Explanatory Mechanisms.

Stigma often is cited as a barrier to the uptake and use of pre-exposure prophylaxis (PrEP) to prevent HIV among Black sexual minority men (SMM). Socialized gender norms (i.e., restrictive emotionality) are associated with experiences and manifestations of stigma in men. However, the association between restrictive emotionality and the stigma surrounding PrEP use has received little attention in previous research. The present study examines the association between restrictive emotionality and holding stigmatizing beliefs about PrEP use with a theoretically informed serial mediation model testing internalized homophobia and LGBT community connectedness as mediators among a sample of 455 Black SMM in the Southeastern US. Results indicate that restrictive emotionality is associated with stigmatizing beliefs about PrEP use. Further, internalized homophobia and LGBT community connectedness were found to partially mediate the proposed relationship serially. Internalized homophobia, but not LGBT community connectedness, also independently mediated the association between restrictive emotionality and stigmatizing beliefs of PrEP use. This study provides important insights into how aspects of masculinity influence the manifestation of stigmatizing beliefs about PrEP use among Black SMM. The present findings have implications for reducing these beliefs, which are known to negatively impact uptake and use of the HIV prevention tool among Black SMM at elevated risk for HIV.
