This paper reviews the literature examining characteristics associated with treatment outcome in women with substance use disorders. A search of the English language literature from 1975 to 2005 using Medline and PsycInfo databases found 280 relevant articles. Ninety percent of the studies investigating gender differences in substance abuse treatment outcomes were published since 1990, and of those, over 40% were published since the year 2000. Only 11.8% of these studies were randomized clinical trials. A convergence of evidence suggests that women with substance use disorders are less likely, over the lifetime, to enter treatment compared to their male counterparts. Once in treatment, however, gender is not a significant predictor of treatment retention, completion, or outcome. Gender-specific predictors of outcome do exist, however, and individual characteristics and treatment approaches can differentially affect outcomes by gender. While women-only treatment is not necessarily more effective than mixed-gender treatment, some greater effectiveness has been demonstrated by treatments that address problems more common to substance-abusing women or that are designed for specific subgroups of this population. There is a need to develop and test effective treatments for specific subgroups such as older women with substance use disorders, as well as those with co-occurring substance use and psychiatric disorders such as eating disorders. Future research on effectiveness and cost-effectiveness of gender-specific versus standard treatments, as well as identification of the characteristics of women and men who can benefit from mixed-gender versus single-gender treatments, would advance the field.

Seeking safety and relapse prevention are efficacious short-term treatments for low-income urban women with PTSD, substance use disorder, and other psychiatric symptoms.

We compared the effectiveness of Seeking Safety (SS), an integrated cognitive behavioral treatment for substance use disorder (SUD) and post-traumatic stress disorder (PTSD), to an active comparison health education group (Women's Health Education [WHE]) within NIDA's Clinical Trials Network. We randomized 353 women to receive 12 sessions of SS (M = 6.2 sessions) or WHE (M = 6.0 sessions) with follow-up assessment at post-treatment and 3-, 6-, and 12-months post-treatment. Primary outcomes were the Clinician Administered PTSD Scale (CAPS) and PTSD Symptom Scale-Self Report (PSS-SR), and substance use (self-reported abstinence in the prior 7 days and days per week of any substance use). Intention-to-treat analysis showed large, clinically significant reductions in CAPS and PSS-SR symptoms (d = 1.94 and 1.12, respectively), but no reliable difference between conditions. Substance use outcomes were not significantly different over time between the two treatments and at follow-up showed no significant change from baseline, when 46% of participants were abstinent. Study results do not favor SS over WHE as an adjunct to SUD treatment for women with PTSD and reflect considerable opportunity to improve clinical outcomes in community-based treatments for these co-occurring conditions. NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript in community based drug treatment, revealing a significant need for therapeutic approaches that can address adverse psychiatric consequences (e.g., Shore, Vollmer, & Tatum, 1989;Breslau, Davis, Andreski, & Peterson, 1991;Resnick, Kilpatrick, Dansky, Saunders, & Best, 1993). Yet, treatment research in this area remains limited.Quasi-experimental and small controlled studies (i.e., Finkelstein et al., 2004) suggest that a services model integrating cognitive behavioral treatment for trauma with substance abuse services can result in modest improvements in outcome (e.g., Amaro et al., 2007;Morrissey et al., 2005). For PTSD without co-occurring substance abuse, cognitive behavioral approaches have shown evidence of efficacy (e.g., Cloitre, Koenen, Cohen, & Han, 2002;Foa, Rothbaum, & Riggs, 1991). There has been concern, however, that discomfort aroused by focusing on the trauma could be harmful in substance dependent patients, who might escalate substance use or flee treatment. At the same time, the demand for specific interventions for patients with trauma and substance abuse has been mounting in community-based treatment systems (Cohen, Dickow, Horner, Zweben, & Balabis, 2003;Morrissey et al.).To address this need, Najavits (2002) developed Seeking Safety (SS), anintegrated cognitive behavioral treatment of PTSD and substance use disorder. Thus far, SS has been researched in various studies including a multisite controlled trial with homeless women veterans (Desai, Harpaz-Rotem, Najavits, & Rosenheck, 2008); two randomized control trials with low-income urban women and adolescent girls (Hien, Cohen, Miele, Litt & Capstick, 2004;Najavits, Gallop, & Weiss, 2006);...

Objective Drug and alcohol abuse constitutes a major public health problem. Computer-delivered interventions have potential to improve access to quality care. The objective of this study was to evaluate the effectiveness of the Therapeutic Education System, an internet-delivered behavioral intervention that includes motivational incentives, as a clinician-extender in the treatment of substance use disorders. Method Adult men and women (N=507) entering 10 outpatient addiction treatment programs were randomly assigned to 12-weeks of treatment-as-usual (n=252) or treatment-as-usual + Therapeutic Education System, whereby the intervention substituted for 2 hours of standard care per week (n=255). Therapeutic Education System consists of 62 computer-interactive modules covering skills for achieving and maintaining abstinence, plus prize-based motivational incentives contingent on abstinence and treatment adherence. Treatment-as-usual consisted of individual and group counseling at the participating programs. Primary outcomes were (1) abstinence from drugs and heavy drinking measured by twice weekly urine drug screens and self-report, and (2) time to drop-out from treatment. Results Compared to treatment-as-usual, those receiving Therapeutic Education System reduced dropout from treatment (Hazard Ratio=0.72 [95% CI, 0.57-0.92], P=.010), and increased abstinence (Odds Ratio=1.62 [95% CI: 1.12-2.35], P=.010), an effect that was more pronounced among patients with a positive urine drug and/or breath alcohol screen at the point of study entry (n=228) (Odds Ratio=2.18 [95% CI: 1.30-3.68], P=.003). Conclusion Internet-delivered interventions, such as Therapeutic Education System, have the potential to expand access and improve addiction treatment outcomes; additional research is needed to assess effectiveness in non-specialty clinical systems and to differentiate the effect of Community Reinforcement Approach and Contingency Management.

Objective-The purpose of the analysis was to examine the temporal course of improvement in Posttraumatic Stress Disorder (PTSD) and substance use disorder symptoms among women in outpatient substance abuse treatment.Method-Participants were 353 women randomized to 12 sessions of trauma-focused or health education group treatment. PTSD and substance use assessments were conducted during treatment and at 1-week, 3-, 6-, and 12-months post treatment. A continuous Markov model was fit on participants' four defined responder categories (non-responder, substance use responder, PTSD responder or global responder [improvement in both PTSD and substance use]) to investigate the temporal association between improvement in PTSD and substance use symptom severity during the study's treatment phase. A generalized linear model was applied to test this relationship over follow-up.Results-Non-responders, substance use responders and global responders tended to maintain original classification; PTSD responders were significantly more likely to transition to global responders over time, indicating maintained PTSD improvement was associated with subsequent substance use improvement. Trauma-focused treatment was significantly more effective in achieving substance use improvement compared to the health education group, but only among those who were heavy substance users at baseline and had achieved significant PTSD reductions.Conclusions-PTSD severity reductions were more likely to be associated with substance use improvement, with minimal evidence of substance use symptom reduction improving PTSD symptoms. Results support the self-medication model of coping with PTSD symptoms and an empirical basis for integrated interventions for improved substance use outcomes in patients with severe symptomatology.
