Positive Masculinity (PM) programs present an opportunity to challenge unequal gender norms and other barriers that hinder the elimination of Violence Against Women and Girls (VAWG) and harmful practices (HPs) in South Sudan. While there are positive masculinity programs engaging men and boys to end VAWG in South Sudan, studies assessing community perceptions of masculinity norms, challenges of engaging men and boys, and effects of positive masculinity programs are scarce. Such studies are needed to further inform approaches and strategies to engage men and boys to end VAWG and HPs.
