The number of individuals with autism spectrum disorders (ASD) diagnoses is increasing rapidly, indicating a need for multi-faceted interventions. The addition of a parent training component to cognitive-behavioral therapy (CBT) has been effectively used to treat a variety of psychological disorders in children to support generalization of skills and to reduce the burden of intensive therapy by using parents as co-therapists. We review these treatments as applied to childhood anxiety, oppositional/conduct, and attention-deficit/hyperactivity problems, as well as ASD-specific treatments that combine CBT with a parent component. The Stress and Anger Management Program, a 9-week emotion regulation treatment for school-aged children with high-functioning ASD, is described here as one example of a group CBT intervention that includes parent training.
