--- - |2 This study aims to understand the associations between adult attachment security and different types of intimate partner violence victimization including that of emotional abuse, physical violence, and sexual coercion among heterosexual couples. Participants included 87 couples with the mean age 22.3 years. An actor–partner interdependence model was fit to the data. Findings indicated that adult attachment security accounted for 15% of the variance in the emotional abuse victimization of females, 9% of the variance in the sexual coercion victimization of females, and 7% of the variance in minor physical victimization of males. This may significantly impact risk factor assessment, and contribute to improved therapeutic intervention and increased understanding of the development and progression of relationship violence. - Journal of Marital and Family Therapy, EarlyView.
