Abstract
Participant retention is one of the more challenging issues in the treatment of substance use disorders. Using data from the National Institute on Drug Abuse Clinical Trials Network's Women and Trauma Study (recruitment in 2004–2005), we examine prominent factors associated with early attrition among women with cooccurring substance use disorders and posttraumatic stress disorder (N = 340). Early treatment attrition is associated with a history of youth partner violence, perceived need for psychological treatment, and abuse of alcohol, opioids, and stimulants. Logistical barriers (e.g., transportation, having children) were not significantly associated with early attrition. Findings provide insight into characteristics of women who might need additional supports to engage in treatment.

The information reported here results from secondary analyses of data from clinical trials conducted as part of the National Drug Abuse Treatment Clinical Trials Network (CTN), sponsored by National Institute on Drug Abuse (NIDA). Specifically, data from CTN-0015 Women's Treatment for Trauma and Substance Use Disorders were included. CTN databases and information are available at www.ctndatashare.org.
Notes
1 Participants were enrolled in standard treatment (“treatment as usual”) that consisted of either individual or group treatment components, reflecting varying orientations and philosophies of addiction treatment.
2 Subthreshold PTSD requires that participants meet either symptom cluster C (avoidant/numbing) or D (hyperarousal), instead of both, as is required for a diagnosis of full PTSD.
3 This measure included all opioids with the exception of heroin. Heroin was measured using a separate variable and was not included in this study due to the low rates of use reported.
