 The faith intervention used peer leadership to decrease HIV stigma and promote testing in African American and Latino congregations. A pilot study found more consistent effects among Latino churches, with facilitators spending more time addressing community-based misconceptions about HIV. The peer leader model was well received, especially among Latinos, and most said they felt comfortable speaking with others about HIV-related topics. Peer leaders reported speaking with up to 20 people within their social networks, particularly with family members. The peer motivator model was found feasible and acceptable across diverse faith settings, but differences in HIV knowledge, social network characteristics, and church preferences may influence overall effectiveness.
