Obsessive-compulsive disorder: tools for recognizing its many expressions.

For a person with symptoms suggestive of obsessive-compulsive disorder (OCD), inquire about a family history of OCD or other anxiety disorders, either of which increases the likelihood of a diagnosis of OCD. Keep in mind that, with children, symptoms suggestive of OCD may simply indicate developmentally appropriate rituals. Become familiar with the alternative methods of assessment to facilitate evaluation in your particular office setting. Consider OCD when a patient exhibits or complains of intrusive thoughts, anxiety-based avoidance of places or objects, excessive reassurance-seeking, or repetitive behaviors/rituals (B).
