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.

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);...
