The Southern Capacity-Building Assistance (CBA) Project seeks to establish and/or maintain HIV prevention programs implemented in collaboration with local community-based organizations (CBOs) serving African-American men who have sex with other men (MSM), women and youth by providing culturally competent capacity-building to those CBOs. Southern CBA is designed to mobilize African-American MSM, women and youth as responsible leaders and key participants in the delivery of HIV prevention services; to increase collaboration among agencies providing HIV prevention services; and increase participation and involvement in the community planning process relative to recruitment, identification and retention of participants.
