What works to change social norms that sustain intimate partner violence in low- and middle-income countries? A systematic review with meta-analyses and meta-regressions
This systematic review and meta-analysis of 36 randomized controlled trials in low- and middle-income countries demonstrates that integrated norm interventions, particularly those combining parent training, couples support, and community mobilization, significantly reduce intimate partner violence and the social acceptability of such violence.

For millions of women around the world, the home is not a sanctuary but a place of danger. Intimate partner violence, the physical, sexual, or psychological abuse inflicted by a spouse or partner, is a leading cause of injury and illness for women globally. It is a problem that persists not just because of individual anger or conflict, but because of the invisible rules that govern how people think a community should behave. These rules are called social norms. They are the shared expectations about what is acceptable, reinforced by friends, family, and neighbors. When a large portion of a community believes that a husband is justified in beating his wife for certain reasons, that belief becomes a powerful force that protects the abuser and silences the victim. Changing these deep-seated beliefs is difficult, and until now, there has been very little hard evidence on which specific actions actually succeed in shifting them, particularly in lower-income nations where the burden of this violence is heaviest.
A researcher set out to solve this puzzle by looking at the collective results of dozens of rigorous experiments conducted in low- and middle-income countries. They gathered data from thirty-six different studies, involving nearly ninety thousand participants, to see what happens when programs try to change these harmful norms. The researcher focused on interventions that explicitly aimed to alter what people believe is socially acceptable, rather than just offering money or counseling without that specific goal. They compared groups that received these programs against groups that did not, looking at whether the violence actually stopped and whether the community's tolerance for it decreased. The findings reveal that these efforts do work, but they also highlight a significant gap between what programs claim to do and how they measure their success.
The analysis showed that these norm-changing interventions led to a real, measurable drop in violence. The odds of a woman experiencing physical violence from a partner decreased by nearly thirty percent. The odds of verbal abuse dropped by a similar amount, and the likelihood of sexual violence fell by about a quarter. Perhaps even more importantly, the programs changed how people thought about the violence itself. The likelihood that a person would say it is acceptable for a husband to beat his wife fell by forty-one percent, and the acceptance of gender inequality dropped by twenty-eight percent. These numbers suggest that when communities are engaged in changing their shared expectations, the behavior of individuals follows suit.
However, the researcher found that not all programs are created equal. The most effective approaches were those that combined three specific elements: training for parents on how to raise children without violence, support for couples to improve their relationships, and community mobilization that brings neighbors together to discuss these issues. When these three components were delivered together, the results were significantly stronger than when they were offered separately. The study also identified specific techniques that made a difference, such as having men participate in the discussions, encouraging critical conversations about power and control within families, and creating a system where participants could lead the change themselves. In contrast, programs that focused solely on giving families money or jobs, without addressing the underlying attitudes about power and violence, showed little to no effect on reducing abuse.
A critical discovery in this review was a disconnect between the theory of the programs and how they were tested. Almost every study claimed to be changing "social norms," which are beliefs about what others in the community think. Yet, nearly all of them measured only "personal attitudes," which are simply what an individual thinks is right or wrong. It is possible for a person to change their own mind while the community around them remains unchanged. Because the studies mostly asked individuals about their own beliefs rather than what they thought their neighbors believed, the researcher could not be certain that the deep social rules had actually shifted, even though the violence did decrease. This suggests that while these programs are successfully changing individual hearts and minds, the next step is to figure out how to turn those personal changes into a new, shared reality for the whole community.
The evidence points toward a clear path forward. To truly reduce intimate partner violence, interventions need to be integrated, bringing together family support, couple counseling, and community action. They must engage men and create spaces where people can question the power dynamics that allow violence to exist. While the results are promising, the researcher cautions that the field is still learning how to measure the most complex part of the problem: the invisible web of expectations that holds a community together. Future work needs to develop better ways to track whether these new, healthier beliefs are spreading from person to person, ensuring that the change is not just a temporary shift in opinion, but a lasting transformation of the social fabric.
