Participation in this study will last 6 months. Participants will be randomly assigned to receive either concurrent parent and adolescent treatment or adolescent only treatment. For those assigned to concurrent treatment, both the adolescent participants and one of their parents will receive individual cognitive behavioral therapy (CBT) counseling sessions and joint family counseling sessions. In the adolescent only treatment condition, adolescent participants will receive individual CBT sessions, but parents will not, and both will receive joint family sessions. Counseling sessions will last 1 hour and occur weekly for 3 months, and then every other week for 3 months. CBT identifies and attempts to change problematic thought patterns. All participants will receive medication consultation if necessary.
