Programs aiming to reduce intimate partner violence (IPV) increasingly seek to shift social norms. Few interventions have been rigorously evaluated for their impact on norms and incidence of IPV, particularly in sub-Saharan Africa. Shifting norms at the community level and subsequent pathways to behavior change remain poorly understood. We assessed shifts in individual- and couple-level factors, social norms, and IPV from an 18-month community-based trial of the Masculinity, Faith, and Peace (MFP) program-a faith-based, norms-shifting approach-in Plateau state, Nigeria. This study was part of a community-based, mixed-methods, two-arm cluster randomized control trial (cRCT) to evaluate the MFP program. Quantitative surveys were conducted with women 18 to 35 years old (n = 350) and their male partners (n = 281). Respondents came from 10 Muslim and 10 Christian congregations. Social norms were measured based on results from factor analysis. Intent-to-treat analyses assessed intervention effects. Qualitative research in MFP congregations explored pathways of change. All forms of IPV reduced over time among MFP participants. Regression analyses showed a significant 61% reduction in odds of reporting experiencing any IPV among women, a 64% reduction among Christians, and a 44% reduction in MFP congregations compared to their respective controls. In addition to improvement in norms, we found significant intervention effects on individual attitudes toward IPV and gender roles, relationship quality, and community cohesion. Qualitative findings reinforce these pathways, suggesting that critical reflection and dialogue on existing norms and the focus on faith and religious texts were valued by participants and supported IPV reductions. This study demonstrates that a faith-based, norms-shifting intervention can significantly reduce IPV in a short time. There are several pathways through which MFP reduced IPV, including shifts in norms, attitudes, relationship quality, and community cohesion.
