title: Intimate Partner Violence Among Same-Sex Couples in College: A Propensity Score Analysis.
abstract: Intimate partner violence (IPV) is a pervasive social issue with numerous detrimental effects on individuals, families, and society. Existing research and a social-ecological minority stress framework suggest, as compared with mixed-sex couples, those in same-sex relationships may be at heightened risk for perpetrating and experiencing IPV. Using a U.S. sample of college students ( N = 4,081), this secondary data analysis contrasted the prevalence of five forms of IPV (i.e., physical, sexual, psychological, injury, any type) between those in mixed-sex ( n = 3,960) and those in same-sex ( n = 121) intimate partnerships. Comparative analyses were supplemented with propensity score weighting to help balance members of mixed-sex and same-sex relationships across eight potentially confounding variables (e.g., biological sex, age). Prior to the application of propensity score weighting, results suggested those in same-sex relationships are significantly more likely to perpetrate and/or experience IPV resulting in physical injury. Results from post-weighting analyses retained the significance and magnitude of model estimates. Taken together, results suggest, as compared with mixed-sex couples, U.S. college students in same-sex couples have greater odds of experiencing IPV perpetration and victimization resulting in physical injury, even after accounting for the influence of several potentially confounding variables. Findings support the utility and future application of propensity score analytic techniques in this type of research as well as the importance of recognizing the unique IPV risk and service needs of people in same-sex relationships.
