Definition of Obsessive-compulsive personality disorder:

Obsessive-compulsive personality disorder is a condition characterized by a chronic preoccupation with rules, orderliness, and control.

Causes, incidence, and risk factors:

This disorder tends to occur in families and thus may have a genetic component. Obsessive-compulsive personality disorder most often occurs in men. It should not be confused with obsessive-compulsive disorder (OCD), which is another psychiatric condition that shares some symptoms with obsessive-compulsive personality disorder.

People with obsessive-compulsive personality disorder believe that their preoccupations are appropriate. They tend to be high achievers and feel a sense of urgency about their actions. They may become extremely upset if others disturb their rigidly ordered routines.
