Modular Cognitive-Behavioral Therapy for an Early Adolescent With Autism Spectrum Disorder and Comorbid Obsessive Compulsive Disorder

This case report outlines the use of a modular cognitive-behavioral therapy (CBT) protocol used to treat Larry, a 12-year-old male, with obsessive compulsive disorder (OCD) and autism spectrum disorder (ASD). Larry participated in 16 weekly 90-min CBT sessions, following a protocol developed for youth with ASD and anxiety/OCD. Upon completion of the treatment, Larry was remitted of his OCD diagnosis (as defined by a subthreshold score of 3 on the Anxiety Disorders Interview Schedule for Diagnostic and Statistical Manual of Mental Disorders-4th ed. [DSM-IV]-parent [ADIS]) and demonstrated marked improvements in his top presenting problems (washing hands immediately after touching something, checking tablet for smudges, and being around litter). This case report indicates useful adaptations to traditional CBT for OCD when working with youth with ASD.
