Now revised and expanded, this is the leading resource for psychotherapists working with adults who have autism spectrum disorder (ASD) without significant cognitive and language impairments (also known as Asperger syndrome). Valerie L. Gaus shows how to adapt the proven techniques of cognitive-behavioral therapy (CBT) to build clients' social and coping skills, facilitate self-acceptance, and treat comorbid anxiety and depression. Illustrated with detailed case examples, the book is grounded in cutting-edge knowledge about information-processing differences in ASD. It gives clinicians critical guidance for conceptualizing these clients' presenting problems and optimizing the effectiveness of interventions.
