Women's substance use and experiences of intimate partner violence: A longitudinal investigation among a community sample

Although cross-sectional studies reveal an association between women's substance use and experiencing physical violence from one's intimate partner, the temporal ordering of these variables is not clearly established. The current study involved longitudinal examination of the association of women's substance use with subsequent experiences of intimate partner violence as well as the association between women's experiences of intimate partner violence and their subsequent substance use. Women ages 18-30 who were in heterosexual relationships (n=724) were recruited through random digit dialing in the Buffalo, NY, area. Within ongoing relationships, women's use of hard drugs was associated with increased odds of experiencing intimate partner violence over the next 12 months. Both marijuana and hard drug use were associated with increased likelihood of experiencing violence in new relationships. Women's heavy episodic drinking did not predict subsequent experiences of partner violence in ongoing or new relationships. Experiences of intimate partner violence had a significant effect on subsequent relationship satisfaction, which was modestly associated with subsequent heavy episodic drinking but not with subsequent drug use.
