The intervention is a refinement of an existing gender-transformative programme that includes community mobilisation and advocacy. Called the Sonke CHANGE intervention, it will extend beyond a conventional group-based workshop approach to address the multi-level nature of violence and create an enabling environment for men to embrace more equitable forms of masculinity. Given the strong associations between masculinities and men's use of partner violence, now is an opportune moment to test the Sonke CHANGE model to determine its impact on men's use of violence.
