ICD-11 Criteria for Obsessive-Compulsive (6B20)

ICD-11 Criteria for Obsessive-Compulsive or Related Disorders (BlockL1‑6B2)

Obsessive-compulsive and related disorders is a group of disorders characterised by repetitive thoughts and behaviours that are believed to share similarities in aetiology and key diagnostic validators. Cognitive phenomena such as obsessions, intrusive thoughts and preoccupations are central to a subset of these conditions (i.e., obsessive-compulsive disorder, body dysmorphic disorder, hypochondriasis, and olfactory reference disorder) and are accompanied by related repetitive behaviours. Hoarding Disorder is not associated with intrusive unwanted thoughts but rather is characterised by a compulsive need to accumulate possessions and distress related to discarding them. Also included in the grouping are body-focused repetitive behaviour disorders, which are primarily characterised by recurrent and habitual actions directed at the integument (e.g., hair-pulling, skin-picking) and lack a prominent cognitive aspect. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning.

6B20 Obsessive-compulsive disorder

Obsessive-Compulsive Disorder is characterised by the presence of persistent obsessions or compulsions, or most commonly both. Obsessions are repetitive and persistent thoughts, images, or impulses/urges that are intrusive, unwanted, and are commonly associated with anxiety. The individual attempts to ignore or suppress obsessions or to neutralize them by performing compulsions. Compulsions are repetitive behaviours including repetitive mental acts that the individual feels driven to perform in response to an obsession, according to rigid rules, or to achieve a sense of ‘completeness’. In order for obsessive-compulsive disorder to be diagnosed, obsessions and compulsions must be time consuming (e.g. taking more than an hour per day) or result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

6B20.0 Obsessive-compulsive disorder with fair to good insight

All definitional requirements of obsessive-compulsive disorder are met. Much of the time, the individual is able to entertain the possibility that his or her disorder-specific beliefs may not be true and is willing to accept an alternative explanation for his or her experience. At circumscribed times (e.g., when highly anxious), the individual may demonstrate no insight.

6B20.1 Obsessive-compulsive disorder with poor to absent insight

All definitional requirements of obsessive-compulsive disorder are met. Most or all of the time, the individual is convinced that the disorder-specific beliefs are true and cannot accept an alternative explanation for their experience. The lack of insight exhibited by the individual does not vary markedly as a function of anxiety level.
