Integrated vs. parallel treatment in adolescents with substance use and comorbid disorders: A randomized trial.

Integrated treatments are often recommended for adolescents with substance use disorders (SUD) and comorbid pathologies. This study aims to compare the effectiveness of two different intervention programs (integrated and parallel) and to investigate treatment outcome predictors. Seventy-five adolescents (13-17 years old) with substance use and comorbid disorders referred to our outpatient program were randomized to integrated (n = 33) or parallel (n = 32) treatment groups.
