This study presents descriptive findings from in-depth interviews with 29 representatives of organizations in Africa, Asia, Europe, Oceania, and North and South America that engage men and boys in preventing gender-based violence. In particular, the findings suggest that strategies are responsive to the specific cultural, economic, and contextual concerns of the local community, with nuanced messages and appropriate messengers. In addition, respondents reported key principles informing their organizational strategies to deepen men and boysÕ engagement. Attention is also paid to respondentsÕ caution about the risks of framing of engagement practices as separate from both womenÕs organizations and women and girls themselves.
