Is obsessive–compulsive disorder (OCD) best categorized as an anxiety disorder? This question has been raised previously, but advances in the psychobiology of OCD and the anxiety disorders, and preparations for Diagnostic and Statistical Manual of Mental Disorders—V and International Classification of Diseases—11, make reconsideration timely.
