Clinical Classification of Obsessive-Compulsive Personality Disorder (OCPD)

a picture of the front cover of the Diagnostic and Statistical Manual of Mental Disorders (DSM)

When working with patients, health professionals often refer to clinical diagnostic manuals to better understand the patient’s illness and potential treatment.

There are two main recognised diagnostic manuals commonly used around the world today. These are the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM) (the latest of which is pictured).  Whilst both manuals generally tend to complement each other, there are differences in the descriptions they use.

You can read a summary of both the ICD and DSM on our clinical classification of OCD page. On this page we will summarise what both diagnostic manuals say about Obsessive-Compulsive Personality Disorder (OCPD).



In ICD-10, The World Health Organization uses the term Anankastic personality disorder which is categorised under the sub-category of Specific personality disorders (F60) which sits under a larger heading of ‘Disorders of adult personality and behaviour‘.

At present it states the following diagnostic criteria for Anankastic personality disorder (Code: F60.5):

Personality disorder characterized by feelings of doubt, perfectionism, excessive conscientiousness, checking and preoccupation with details, stubbornness, caution, and rigidity. There may be insistent and unwelcome thoughts or impulses that do not attain the severity of an obsessive-compulsive disorder.
