Treatment for Teens With Alcohol Abuse and Depression

The investigators will recruit adolescents with alcohol or cannabis abuse and clinically significant depression. All participants will receive 12 sessions of an evidence-based treatment for alcohol abuse, Motivation Enhancement Therapy/Cognitive Behavior Therapy-12, over 12 to 14 weeks. Those who are still depressed after 4 weeks will be randomized to receive treatment augmentation with either an integrated cognitive behavior therapy for depression, delivered by their study therapist, or depression treatment-as-usual in the community. The study hypothesis is that integrated depression treatment will surpass community treatment-as-usual in efficacy.
