«The authors provide a clear, concise guide to the puzzle of OCD and ASD. There is clear advice on how to adapt CBT for OCD including key aspects such as the differences between compulsions and repetitive behaviours and obsessions and special interests. This volume is invaluable to those who are already familiar with OCD but less experienced in ASD. The authors speak with confidence and experience about how to adapt treatment to make the most of the powerful aspects of ERP whilst remaining sensitive to the particular needs of people with ASD. This is reassuring to novice practitioners to be aware of certain "do's and don'ts" and enlightening for both novice and experienced therapists when considering the nuance and detail of effective CBT.»

«Drs. Russell, Jassi, and Johnston should be congratulated for filling a critical gap in the literature by crafting an evidence-based adaptation of cognitive-behavioral therapy for supporting individuals with autism and co-occurring OCD. The text is clear, informed by the latest scientific findings, and will successfully disseminate established interventional approaches to practicing clinicians.»
