Intimate partner violence (IPV) is a substantial health concern and identifying risk factors for IPV is a research priority. We examined the relationship between severe IPV and objectification of the self and other sex across participant sex. A sample of 1,005 male and female university students completed a series of online questionnaires that measure levels of self-objectification, objectification of the other sex, and histories of severe IPV victimization and perpetration. Self-objectification was associated with severe psychological aggression, physical assault, and sexual coercion victimization in females, but not in males. Objectification of the other sex was associated with severe psychological aggression and physical assault perpetration in males, but not in females. These findings contribute to our understanding of gender similarities and differences in IPV.
