Although attitudes toward intimate partner violence (IPV) have been the subject of many studies, little research has been conducted to comparatively assess public definitions of IPV in Western and non-Western countries. Drawing upon survey data collected from approximately 500 Chinese and American college students, this study compared and contrasted Chinese and American college students in their beliefs about what constitute IPV. Chinese students were found to be less likely to define abusive acts as IPV than their U.S. counterparts. Gender-role attitudes, such as beliefs of male dominance and IPV as crime, were among the most prominent predictors of students’ definitions of IPV. Chinese and American college students’ attitudes differed not only in what was defined as IPV, but also in what were the factors that shaped such attitudes. Directions for future research and policy were discussed.
