Abstract

Background

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

Purpose

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.

Methods

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

Results

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.

Conclusions

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