What Client Demographic, Substance Use, Mental Health, Treatment, and Psychological Variables Predict Residential Treatment Completion for Substance Use Disorders?

Abstract

AbstractResidential treatment is a common option for individuals with moderate to severe substance use disorders. In a cohort of individuals who accessed residential treatment, we investigated client demographic, substance use, mental health, treatment, and psychological predictors of treatment completion. Participants were a retrospective cohort of 1056 (15–69 years) individuals admitted to residential treatment facilities across Queensland, Australia, from January 2014 to December 2016. Participant characteristic information was obtained at admission, including the Depression Anxiety Stress Scale 21 (DASS-21). A multiple logistic regression model was conducted with treatment completion as the outcome. The overall rate of treatment completion was 14.3%. Mild to moderate (aOR = 0.48 [0.28–0.84], p = .010) and severe to extremely severe (aOR = 0.35 [0.17–0.74], p = .006) stress on the DASS-21 at service entry was significantly associated with a lower likelihood of treatment completion. Participants with higher levels of stress at service entry were less likely to complete treatment, representing a missed opportunity to provide targeted support during high-risk periods for individuals with substance use disorders. Further research investigating the nature and causes of stress in-between, during, and following presentations to residential treatment is needed.
