Comorbidity is a well established aspect of adolescent psychopathology. The majority of adolescents entering treatment have more than one condition. This study will evaluate service delivery methods of integrating empirically supported interventions for depression and non-nicotine substance use disorders (SUD)in an effort to improve treatment engagement, response, and maintenance of gains. The two examined interventions are the Adolescent Coping With Depression course (ACWD) and Functional Family Therapy (FFT).
