In this study phase, 36 patients with a disruptive behavior disorder (DBD - i.e., attention deficit-hyperactivity disorder, oppositional defiant disorder, conduct disorder) and use or abuse of one or more substances will be randomly assigned to treatment using either a standard treatment for DBDs in this age group or the newly developed HBT treatment. Treatment outcomes for the 24 patients assigned to receive HBT will then be compared to outcomes for the 12 patients assigned to receive standard DBD treatment.
