Adolescent substance use treatment: the moderating effects of psychopathology on treatment outcomes.

The present study tested the influence of co-occurring mental health diagnoses on the relationship between length of stay and treatment outcome among adolescents residing in an inpatient substance abuse treatment facility. Data were collected via record review. Follow-up information was obtained at 7 days and 3 months post-discharge. Treatment outcome was defined as abstinence and engagement in recovery activities. Hierarchical linear regression demonstrated that comorbidities differentially moderated the relationship between length of stay and treatment outcome. Results suggest that these adolescents attempt to engage in recovery activities independent of abstinence and may need supplemental aftercare assistance to maintain their efforts.
