Violence against women and girls (VAWG) is highly prevalent in Haiti and constitutes a serious public health problem. Social norms promoting power imbalance between women and men and condoning VAWG are also widespread. Changing these norms and curbing the cycle of VAWG in Haiti is an important step toward ensuring healthier, more productive, and safer communities in Haiti. This report documents the lessons learned from a review of the planning, implementation, and evaluation of community mobilization interventions concerning VAWG in Haiti, namely the SASA program by Raising Voices and the Power to Girls program by Beyond Borders. The methods used to develop this report consist of a review of the literature on VAWG prevention programs, as well as qualitative data collection with key informants in Haiti. Findings from this analysis will contribute to the broader literature on adapting, testing, implementing, and evaluating evidence-based interventions in developing countries
