Obsessive-compulsive disorder (OCD) is a neuropsychiatric disorder characterized by obsessions or compulsions (or both) that are distressing, time-consuming, or substantially impairing.
Criteria for the Diagnosis of Obsessive–Compulsive Disorder (OCD)
- Obsessions are recurrent thoughts, urges, or images that are experienced, at some time, as intrusive and unwanted.
- The person attempts to ignore or suppress such thoughts, urges, or images, or to neutralize them with some other thought or action (i.e., by performing a compulsion).
- Compulsions are repetitive behaviors (e.g., hand washing, ordering, and checking) or mental acts (e.g., praying and counting) that the person feels driven to perform in response to an obsession.
- The goal of the compulsive behavior is to prevent or reduce anxiety or distress or prevent some feared outcome.
Symptoms causing impairment
- Obsessions or compulsions are time consuming (>1 hr/day).
- There is clear evidence that the symptoms cause the person distress or interfere with or reduce the quality of social, academic, or occupational functioning.
- Symptoms are not better accounted for by another mental disorder (e.g., depression or anxiety disorder) and are not solely attributable to the effects of a substance (e.g., a drug of abuse or medication).
- Insight specifier: Persons with OCD have varying levels of insight (i.e., ability to recognize that their beliefs are definitely or probably not true); poorer insight (when the person is mostly convinced that their beliefs and behaviors are not problematic, despite evidence to the contrary) has been associated with poor long-term outcome.
- Tic-related specifier: When a person has a tic disorder or history of a tic disorder, this specifier reflects possible different patterns of coexisting conditions, course of illness, and familial transmission.
† Specifiers clarify features of the disorder but are not required for a diagnosis.
