The role of illicit substance use in a conceptual model of intimate partner violence in men undergoing treatment for alcoholism

Illicit substance use (ISU) predicts intimate partner violence (IPV) above and beyond alcohol use and other known IPV correlates. Stuart and colleagues (2008) provided evidence for a theoretical framework by which ISU contributes both directly and indirectly to IPV. We sought to replicate and extend their findings using data from 181 married or cohabiting heterosexual couples in which the male had recently begun a substance abuse treatment program and met criteria for alcohol dependence (97%) or abuse (3%). Using SEM, we found that (a) Stuart et al.'s model provided a good fit to the data; (b) men's cocaine use and women's sedative use emerged as particularly relevant to their respective perpetration of IPV; (c) a positive association between men's antisociality and physical aggression was mediated by increased stimulant use; and (d) the specific pattern of IPV predicted by women's sedative use differed across levels of aggression severity. These findings not only highlight the direct role of ISU in relationship aggression, but also support a larger theory-driven model comprising various proximal and distal precursors of IPV.     

Drug-abusing patients and their intimate partners: dyadic adjustment, relationship stability, and substance use

The dyadic adjustment and substance use of couples with a drug-abusing husband (n = 94), couples with a drug-abusing wife (n = 36), couples in which both partners abused drugs (n = 87), and non-substance-abusing conflicted couples (n = 70) were examined. For couples with 1 drug-abusing partner, a higher percentage of days abstinent during the year before treatment for drug abuse was associated with a higher level of relationship satisfaction. When both partners abused drugs, the relationship between percentage of days abstinent and relationship satisfaction became stronger and more negative as the time partners spent together using drugs increased. A higher percentage of days abstinent was associated with relationship stability for couples with 1 drug-abusing partner during and 1 year after treatment; for couples in which both partners abused drugs, a higher percentage of days abstinent was associated with relationship instability.     

Intimate partner aggression reporting concordance and correlates of agreement among men with alcohol use disorders and their female partners

This study examined relationship aggression reporting concordance among 303 men with alcohol use disorders and their female partners enrolled in couples-based alcohol abuse treatment. Agreement for physical and psychological aggression was generally consistent with, or higher than, concordance rates reported among other populations. Men's antisocial personality disorder characteristics were the strongest predictor of higher concordance for male- and female-perpetrated aggression. Higher alcohol problem severity, poorer relationship adjustment, and higher psychopathic personality features were associated with better concordance in some analyses. Women reported experiencing more physical aggression than men reported perpetrating, and women reported perpetrating more psychological aggression than men reported experiencing. Findings highlight the importance of obtaining aggression reports from both partners and the need for research investigating methods for improving concordance.
