Childhood Sexual Abuse and Intimate Partner Violence among Women in Methadone Treatment: A Direct or Mediated Relationship?

Abstract

Women in substance use treatment report rates of childhood sexual abuse and intimate partner violence that far exceed those reported by women in the general population. Previous research with nonrandom samples of women in substance use treatment suggests that there is a statistically significant relationship between childhood sexual abuse and intimate partner violence; however, little is known about the mechanisms of risk between these two public health concerns among this population of women. To address this gap in knowledge and to inform intervention strategies, this study examined direct and mediated relationships between childhood sexual abuse and intimate partner violence risk among a random sample of 416 women in methadone treatment. In addition to high rates of childhood sexual abuse (57.9%), intimate partner violence (lifetime prevalence, 89.7%; 6-month prevalence, 78.4%), posttraumatic stress disorder (PTSD, 28.6%), and global psychological distress (19.5%), findings suggest that the relationship between childhood sexual abuse and intimate partner violence is mediated by mental health problems and that women experiencing PTSD or global psychological distress are 2.7 and 2.4 times more likely to experience intimate partner violence than women without such experiences, respectively. Although not a mediator in this relationship, financial independence reduced women's risk of partner violence by two-thirds. The paper includes discussion of social learning and stress and coping theories to explicate the findings and to inform intervention strategies.
