A culturally congruent training program to promote HIV risk-reduction behaviors was implemented in a convenient sample of 9 African-American women in an urban methadone treatment program. At each of eight peer counseling and leadership training (PCLT) program sessions, the transmission and prevention of AIDS were discussed while emphasizing enhancement of participants' self-esteem, confidence, and control over high-risk behaviors. The results indicate that support of the women helped develop their sense of purpose and self-worth, reduced sexual and drug use practices associated with risk for HIV and AIDS infection, and promoted assumption of leadership roles and dissemination of accurate AIDS-related information in their communities. It was apparent that knowledge alone does not change behavior if it conflicts with established norms, values, beliefs, and life-styles and that individuals who have a sense of personal control are more willing to explore alternative lower-risk behaviors.
