Evaluating a microeconomic intervention for high risk women in India

Chennai, India


The current study will examine the effects of a microenterprise intervention on incident HIV and sexually transmitted infections among a sample of street-based sex workers in Chennai, India. Specifcially, the study aims: 1. determine the effect of the POWER intervention on incident HIV/STIs and sexual risk behaviors; 2. assess if intrapersonal, interpersonal, and economic factors mediate the POWER intervention’s effect on sexual risk behaviors; 3. conduct economic evaluations to examine the intervention’s cost (cost analysis) and cost per HIV infection averted (cost-effectiveness); and to 4.examine the intervention’s sustainability through women’s involvement in bag-making after graduating from the intervention arm. The study will be conducted in two phases. . Phase I will be comprised of two components and will occur over a period of six months. First, recruitment venues will be identified through participant observations and ethnographic mapping. Secondly, we will conduct a series of 4-8 focus groups (n= 40-80) to examine key study concepts (e.g., empowerment, teamwork, job self efficacy) which will inform both the intervention and the study’s surveys. Phase II is comprised of an intervention trial in which 500 women will be randomly assigned to an intervention (100 hours of tailoring) or control arm (100 hours of English lessons) and will be followed at 6-, 12-, and 18-months with locator visits at intermediate months to enhance retention. Women will undergo HIV/STI testing and counseling at baseline and the three main follow-up study visits.
