A growing body of research indicates that gender-based violence (GBV) is a major global public health challenge. Yet, there is a dearth of evidence to guide program planning and policy-making efforts to reduce GBV. Our study will evaluate the feasibility, safety, and potential effectiveness of an innovative women's empowerment intervention to reduce GBV and related adverse health outcomes. It is expected that the study findings will provide evidence to determine if a phase 3 effectiveness trial is merited and advance the science underlying GBV prevention.
