A significant amount of literature exists on the lasting effects of interparental abuse on children’s psychological health as adults. However, evidence on how children’s childhood experience of interparental violence shapes their attitude toward partner violence in adult intimate relationships is limited. Given the existing evidence that women’s acceptance of partner violence as a social norm increases the risk of partner violence, we analyzed the effect of girls’ witnessing interparental abuse (where a father is a perpetrator) on their attitude toward partner violence in their intimate relationships as adults. We used data from the Demographic and Health Surveys for 31 low and middle-income countries in Asia and Africa. Aggregating information about women’s attitudes toward partner violence into a binary “intimate partner violence acceptance” variable, we found that a woman who witnessed her father beat her mother was 1.62 times more likely to justify partner violence than a woman who did not experience such interparental abuse (adjusted odds ratio [ AOR] = 1.62, 95% CI [1.57, 1.66], p < .001). Additionally, using individual components of acceptance as response variables, we found that a woman who witnessed interparental abuse was significantly more likely to justify partner violence if she went out without telling her husband ( OR = 1.49, 95% CI [1.45, 1.54], p < .001), neglected children ( OR = 1.53, 95% CI [1.49, 1.58], p < .001), argued with the husband ( OR = 1.49, 95% CI [1.45, 1.53], p < .001), refused sex with the husband ( OR = 1.35, 95% CI [1.31, 1.39], p < .001), or burned food ( OR = 1.36, 95% CI [1.31, 1.41], p < .001). This study highlights the need to put in place children-specific social policies to limit the intergenerational transmission of the adverse effects of intimate partner violence.
