Predictors of outcome for patients with substance-use disorders five years after treatment dropout.

OBJECTIVE: Few studies focus on the outcome of patients after they drop out of substance-use disorder (SUD) treatment, and there appear to be no prior studies of the long-term outcomes of these patients. The aim of this study is to determine how well such patients do after dropping out of treatment and to identify predictors of differential outcomes.
METHOD: Patients in 15 residential SUD treatment programs were assessed at treatment entry and at 5-year follow-up on their frequency and severity of substance use, expectancies and beliefs about substance use, and social resources and stressors. Patients who dropped out and stayed out of treatment (n = 193) were compared with those who completed treatment (n = 3,204). Predictors of 5-year SUD problems among dropouts were identified.
RESULTS: In general, dropouts and treatment completers did not differ significantly on their levels of SUD problems at 5 years. At baseline, patients who dropped out reported more involvement in 12-step organizations and greater cognitive impairment and more closely identified with the label "drug addict" than "alcoholic." Lower severity of SUD, lower self-efficacy, fewer positive substance- use expectancies, and less stress from social networks predicted fewer SUD problems at 5 years among dropouts.
CONCLUSIONS: In addition to focusing on substance use, providers should address the adequacy of patients' social support and counter positive substance-use expectancies at the earliest stages of treatment before patients drop out.
