Few HIV prevention interventions focus on sexual risk reduction as mutual process determined by couple members, though risk behaviors are inter-dependent.


This trial examined the impact of substance use, history of sexual trauma, and intimate partner violence on sexual risk associated with participation in a risk reduction intervention.


HIV seroconcordant and serodiscordant multicultural couples in Miami, Florida (n = 216) were randomized to group (n = 112) or individual (n = 104) couple-based interventions.


Group intervention participants increased condom use in couples in which women had a history of sexual trauma [F(2,221) = 3.39, p = 0.036] and by partners of alcohol users. History of sexual trauma was a determinant of conflict resolution, predicting negative communication and intimate partner violence.


Results emphasize the need for group sexual risk reduction interventions targeting sexual trauma, partner violence, and substance use among HIV seroconcordant and serodiscordant couples.
