Co-Occurring Autism and Obsessive-Compulsive Disorder: Evidence-Based Assessment and Intervention

Abstract

Co-occurring pediatric autism and obsessive–compulsive disorder (OCD) present significant challenges for accurate assessment and effective psychotherapy. Overlapping features, particularly repetitive behaviors and rigidity, often obscure diagnostic clarity and complicate treatment planning. This article uses a clinical vignette to illustrate the nuanced differentiation between autism-related restricted and repetitive behaviors and interests and OCD-related compulsions, emphasizing functional distinctions such as ego-syntonic versus ego-dystonic experiences. Key clinical and ethical challenges, including diagnostic overshadowing and risks of misaligned intervention, are also reviewed. Evidence-based recommendations are provided for comprehensive, developmentally informed assessment and for adapting cognitive-behavioral therapy with exposure and response prevention to meet the needs of autistic youth. Practical strategies are offered to support informed, individualized clinical decision-making.
