This study assessed and compared the efficacy of culturally tailored behavioral interventions to increase use and acceptability of sexual barrier products among HIV-positive women in Zambia. It also sought to evaluate cultural preferences as facilitators or impediments to potential use of vaginal chemical barriers for sexual risk reduction within the Zambian context. Women (N=240), recruited from the University Teaching Hospital HIV Voluntary Counseling and Testing Center, were randomized into group or individual intervention arms. Participants attended a baseline assessment, three intervention sessions and follow up assessments at six and 12 months. All participants increased use and acceptability of female condoms and vaginal products and maintained male condom use at six and 12 months. Preliminary data indicated that group participants increased male condom use at six months and trial use and acceptability of female condoms and lubricants predicted their use in the group condition. Results support group interventions to increase sexual barrier use and acceptability in HIV-positive women within the Zambian context. From a public health standpoint, groups may represent a cost-effective and culturally congruent intervention.
