Overview
Obsessive compulsive disorder is classified in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) as an anxiety disorder. According to the American Psychiatric Association there will be change in the classification of OCD and associated conditions into DSM-5 once the the fifth edition of the DSM scheduled for release in May 2013 comes out.
Classification
Obsessive-compulsive disorder: subclassification based on co-morbidity.
The three-class solution is characterized by:
(1) An OCD simplex class, in which major depressive disorder (MDD) is the most frequent additional disorder;
(2) An OCD co-morbid tic-related class, in which tics are prominent and affective syndromes are considerably rarer; and
(3) An OCD co-morbid affective-related class in which panic disorder and affective syndromes are highly represented.
The OCD co-morbid tic-related class is predominantly male and characterized by high conscientiousness. The OCD co-morbid affective-related class is predominantly female, has a young age at onset, obsessive-compulsive personality disorder (OCPD) features, high scores on the 'taboo' factor of OCD symptoms, and low conscientiousness.
