In addition to the core symptoms, children and adolescents with Autism Spectrum Disorder (ASD) often exhibit disruptive behavior problems including irritability, tantrums, noncompliance, and aggression. This is a pilot study of Cognitive-Behavioral Therapy, also known as Anger Control Training, in adolescents with high-functioning ASD. CBT teaches children to recognize antecedents and consequences of problem behavior and to use emotion regulation and problem-solving skills to reduce irritability, aggression and noncompliance. This form of CBT has been well-studied in typically developing children with disruptive behavior and we are investigating if this treatment can be feasible and helpful, with appropriate modifications, for irritability and disruptive behavior in ASD.
