The Women, Co-occurring Disorders, and Violence Study (WCDVS) was a multi-site cooperative study to evaluate new service models for women with co-occurring mental health and substance use disorders and a history of physical and/or sexual abuse. Despite common features in the service interventions and evaluation procedures, diversity across the nine sites plus differences introduced by non-random assignment led to numerous methodological challenges. This article describes the design, measurement, and analysis decisions behind the WCDVS and lays the foundation for understanding participant-level outcomes and service costs. This article also describes the study population, as recruited and following attrition at the 6-month follow-up, in order to address the threat of selection bias to inferences drawn from this multi-site study.

    • "Emerging research demonstrates that the complicated issues presented by this population are best met through integrated intervention models that address the most salient issues facing this population—victimization, mental disorders, and substance use (Cocozza et al., 2005; Logan et al., 2006). Specifically, findings from the Women, Co-occuring Disorders, and Violence Study (WCDVS) demonstrated that interventions providing highly integrated treatment of victimization, substance use, and other mental disorders exhibited a greater effect on drug use severity and mental health outcomes than interventions with less integration (see McHugo et al., 2005 for a detailed description of the WCDVS research methods; Clark & Power, 2005; Cocozza et al., 2005; Morrissey et al., 2005). Moreover, women with more severe problems received a greater benefit from integrated services than those with less severe problems (Morrissey et al., 2005). "

    ABSTRACT: Women are the fastest growing segment of the criminal justice population, yet the majority of research on criminal justice populations has been focused on men. Programming and interventions that reduce women’s involvement in the criminal justice system and ameliorate the negative consequences associated with criminal justice involvement are urgently needed. The overall aim of this paper is to provide a comprehensive framework for developing evidence-based, gender-specific programming and interventions to reduce criminal justice involvement and its associated consequences among women in the criminal justice system. The first section of the paper offers a conceptually guided review of the three primary factors that facilitate and complicate women’s involvement in the criminal justice system: victimization; mental disorders; and substance use. In the second section of the paper, findings from focus groups conducted with women on probation or parole identify strategies to engage this population in psychosocial interventions. The third and final section of the paper provides comprehensive recommendations for designing programming and interventions for women in the criminal justice system.

    • "There were 2,729 study participants at baseline, each of whom had mental health and substance use disorders (of which one was currently symptomatic, the other within the previous five years) and a lifetime history of abuse victimization (McHugo et al., 2005). At baseline, participants were, on average, high-intensity users of addiction treatment, and over half were living in residential substance abuse treatment facilities (Becker et al., 2005). "

    ABSTRACT: OBJECTIVE: The current study examined whether clinical responses to an integrated treatment intervention among women with co-occurring disorders and histories of abuse varied according to their service use patterns at baseline. METHODS: Data were from a national, multi-site, integrated treatment intervention study in 1998-2003. Analyses included 999 study participants assigned to the integrated treatment group and who were symptomatic at baseline. Participants' baseline service use activity was characterized according to five distinct baseline service use clusters. Logistic regression models estimated study participants' odds of good clinical responses to integrated treatment at 12 months across the five service clusters. RESULTS: Participants with high levels of psychotropic medication and medical care use at baseline had significantly lower odds than low-intensity service users of having a good response to integrated treatment at 12 months on mental health, alcohol addiction, and posttraumatic stress measures. A majority of women in this group had serious medical illness or disability and were more likely than their counterparts with other service use patterns to have used homeless or domestic violence shelters. CONCLUSIONS: Women who used high levels of medication and medical services appear to have faced especially difficult barriers in responding well to integrated treatment. Careful assessments of their mental health, trauma, and medical treatment needs may be required as part of integrated treatment in an effort to improve their response to integrated treatment, clinical outcomes and well-being. This information can also be used to target integrated treatment to women who are likely to respond positively and achieve meaningful improvements in their functioning.

    • "Four core requirements for the content of the interventions were: (1) to provide comprehensive intervention services with eight specific service elements, including outreach and engagement, parenting skills training, resource coordination and advocacy, and crisis intervention; (2) to implement a set of services that were integrated, both clinically and organizationally (i.e., a site needed to be coordinated with other agencies and individual providers participating in the care of study participants); (3) to provide services that were trauma-informed, so that potential circumstances and symptoms specific to having been a victim of abuse were to be acknowledged and addressed in the intervention services; and, (4) to incorporate CSR involvement into their intervention services. Specifically, [C]onsumers of mental health services, [S]urvivors of trauma, and women in [R]ecovery (CSR) were to be included in the development, implementation, and evaluation of each site's intervention services (McHugo et al. 2005).

    ABSTRACT: Women with co-occurring mental health and substance use disorders and trauma histories vary greatly in symptom severity and use of support services. This study estimated differential effects of an integrated treatment intervention (IT) across sub-groups of women in this population on services utilization outcomes. Data from a national study were used to cluster participants by symptoms and service utilization, and then estimate the effect of IT versus usual care on 12-month service utilization for each sub-group. The intervention effect varied significantly across groups, in particular indicating relative increases in residential treatment utilization associated with IT among women with predominating trauma and substance abuse symptoms. Understanding how IT influences service utilization for different groups of women in this population with complex needs is an important step toward achieving an optimal balance between need for treatment and service utilization, which can ultimately improve outcomes and conserve resources.
