We analyzed 498 effect sizes about the relationship between ambivalent sexism and attitudes toward male-to-female violence, and 133 effect sizes about the relationship between ambivalent sexism and violent behavior. The results showed that hostile sexism is more strongly associated with both attitudes toward violence (r = .517) and violent behavior (r = .250) than benevolent sexism is (r = .328 and r = .049, respectively). The type of violence and the target of violence are the significant moderators for hostile sexism: the smallest effect size was observed for attitudes toward physical violence and the weaker correlation between hostile sexism and violent behavior was where an intimate partner was involved. Our findings revealed that gender and sample type were not significant moderators while the higher the level of equality in the country where the study was conducted, the higher the correlation between benevolent sexism and attitudes toward violence.
