Diagnosis of Obsessive compulsive disorder

OCD tends to be under-diagnosed and under-treated. A GP who diagnoses OCD will refer the individual to a psychiatrist or psychologist who is experienced in treating OCD.

The Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) classifies OCD as an anxiety disorder since the recurrent obsessions and compulsions can be severe enough to be time-consuming, cause marked distress or significant impairment.

Diagnosis is based on the following:

  • Symptoms cause significant distress
  • Symptoms take up more than 1 hour a day
  • Symptoms significantly interfere with work, relationships, or daily functioning
  • The person recognizes that his or her obsessions and compulsions are unreasonable or excessive.
