Testing the Efficacy of Safe South Africa

Overview

In this study, investigators will examine the efficacy of Safe South Africa, a behavioral intervention that is developmentally- and gender-tailored to prevent human immunodeficiency virus (HIV) and intimate partner violence (IPV) among adolescent boys. South Africa faces some of the highest global rates of HIV and IPV with sustained high incidence of HIV and alarming rates of IPV among adolescents and thus, is an ideal site to advance prevention science to tackle these urgent public health priorities. Testing the efficacy of an integrated intervention to prevent HIV risk behavior and IPV for adolescent boys can support optimal health for young people, their future partners, and society.

Adolescence presents an ideal developmental transition period for an integrated intervention targeting prevention of HIV risk behaviors and intimate partner violence (IPV), including sexual violence. Adolescent boys in particular are at high risk for HIV and perpetration of IPV. Yet, few behavioral interventions integrate HIV-IPV prevention and are tailored for the unique developmental needs of adolescent boys. In this study, investigators build on previous scientific work that demonstrated the acceptability and feasibility of Safe South Africa, an integrated HIV-IPV intervention that uses a developmentally- and gender-tailored approach grounded in social norms theory to prevent adolescent HIV risk behavior and IPV. Investigators will conduct the work in South Africa, a country with the largest HIV epidemic and some of the highest rates of IPV in the world. The investigative team propose the following specific aims: (1) Tailoring Safe South Africa intervention content to address the unique behavioral and social norms data that drives HIV and IPV behaviors among boys in their socioecological environments. (2) Testing the efficacy of the Safe South Africa intervention in preventing HIV/STIs and reducing IPV frequency among N=836 adolescent boys (ages 15- 17), with the scientific team's working hypothesis that the intervention, relative to the usual care condition, will show (a) lower incidence of any STI (including HIV); and (b) reductions in IPV perpetration frequency and decreased endorsement of IPV supportive attitudes. (3) Identifying barriers and facilitators to implementing Safe South Africa within a school setting to provide data for future dissemination (presuming Safe South Africa is efficacious). Investigators will examine processes critical to future dissemination through (a) fidelity data examining adherence to core active components of the standardized intervention manual guiding consistent delivery of the intervention; and (b) qualitative data on the experience during and post-implementation from adolescents and stakeholders using N=20 in-depth interviews with each group.
