In 2015, AIDSFree conducted a review of the PEPFAR Gender-Based Violence Initiative (GBVI) in the Democratic Republic of Congo, Mozambique, and Tanzania. The $55 million, three-year, interagency initiative integrated GBV prevention and response into existing HIV prevention, care, and treatment programs at health facility, community, and policy levels. The review sought to inform programming, specifically the integration of GBV prevention and response into the context of the HIV cascade of services, and identify lessons that can inform PEPFAR and other donor initiatives in designing future investments in GBV prevention and response. This report synthesizes the findings and lessons learned from the three country reviews and analysis of the PEPFAR indicator data collected over the three years.
