Objectives. We examined whether frequent drug use increases the likelihood of subsequent sexual or physical intimate partner violence (IPV) and whether IPV increases the likelihood of subsequent frequent drug use. Methods. A random sample of 416 women on methadone was assessed at baseline (wave 1) and at 6 months (wave 2), and 12 months (wave 3) following the initial assessment. Propensity score matching and multiple logistic regression were employed. Results. Women who reported frequent crack use at wave 2 were more likely than non-drug using women to report IPV at wave 3 (odds ratio [OR] = 4.4; 95% confidence interval [CI] = 2.1, 9.1; P < .01), and frequent marijuana users at wave 2 were more likely than non-drug users to report IPV at wave 3 (OR = 4.5; 95% CI = 2.4, 8.4; P < .01). In addition, women who reported IPV at wave 2 were more likely than women who did not report IPV to indicate frequent heroin use at wave 3 (OR = 2.7; 95% CI = 1.1, 6.5; P = .04). Conclusions. Our findings suggest that the relationship between frequent drug use and IPV is bidirectional and varies by type of drug.
