Risk and protective factors of same-sex intimate partner violence in Hong Kong.

Numerous studies have assessed risk and protective factors for intimate partner violence (IPV) among heterosexual couples around the globe. Nevertheless, few have addressed the same issue among same-sex couples, especially in cultures where same-sex intimate relationships have gained little acceptance. This exploratory study evaluated the substantial risk and protective factors for same-sex IPV based on gender-neutral theories. Three hundred and six Hong Kong residents who have been in a same-sex romantic relationship completed a web-based questionnaire. Logistic regression analyses indicated that relationship conflict and poor anger management were risk factors both of psychological and physical perpetration. Dominance and substance abuse were respectively associated with psychological aggression and physical battering despite their small effect sizes. Psychological aggression was also found to mediate the relationship between conflict and physical assault, and that between anger management and physical assault. Interventions related to the array of risk and protective factors were discussed and recommended.
