DSM-IV-TR Criteria for Obsessive-Compulsive Disorder (DSM code 300.3)

Either obsessions or compulsions
Obsessions defined by all of the following:
• recurrent and persistent thoughts, impulses, or images experienced, at
some time during disturbance, as intrusive and inappropriate and cause
marked anxiety or distress
• thoughts, impulses, or images not simply excessive worries about reallife
problems
• attempts made to ignore or suppress thoughts, impulses, or images, or
to neutralize them with some other thought or action
• recognition that thoughts, impulses, or images are product of his or her
own mind (not imposed from without, as in thought insertion)
Compulsions defined by both of the following:
• repetitive behaviors (hand washing, ordering, checking) or mental acts
(praying, counting, repeating words silently) that individual feels driven
to perform in response to an obsession or according to rules that must
be applied rigidly
• behaviors or mental acts aimed at preventing or reducing distress or preventing
some dreaded event or situation; behaviors or mental acts either
are not connected in a realistic way with what they are designed to neutralize
or prevent or are clearly excessive
At some point, individual recognizes obsessions or compulsions as excessive
or unreasonable; this does not apply to children
Obsessions or compulsions cause marked distress, are time-consuming, or
interfere significantly with normal routine, occupational or academic functioning,
or usual social activities or relationships
If another Axis I disorder is present, content of obsessions or compulsions
not restricted to it
Disturbance not due to direct physiological effects of a substance or general
medical condition
Specify if with Poor Insight (most of the time during current episode, obsessions
and compulsions not recognized as excessive or unreasonable)
