Gender-transformative interventions have been found to help ameliorate gender-inequitable norms and improve health outcomes for women and men. While narrative-based strategies are increasingly being used in public health programs, no evaluation publications exist to date for gender-transformative programming that employs men’s public narrative-sharing as a central means for promoting healthy masculinities. The Men’s Story Project (MSP) creates live productions in which diverse men publicly perform personal narratives that challenge hegemonic masculinity, promote gender equality, and highlight intersections of masculinity with other social identities. This study draws upon six focus groups with thirty-one audience members (AMs), two weeks after an MSP production at a US public university. The MSP led AMs to reevaluate key pillars of hegemonic masculinity, including a singular conception of masculinity, essentialist notions of gender, restricted emotional expression, and use of violence; AMs also gained an expanded understanding of intersectionality. Directions for future research are discussed.
