Obsessive–compulsive personality disorder (OCPD), also called anankastic personality disorder, is a personality disorder characterized by a general pattern of concern with orderliness, perfectionism, excessive attention to details, mental and interpersonal control, and a need for control over one's environment, at the expense of flexibility, openness, and efficiency. Workaholism and miserliness are also seen often in those with this personality disorder. Rituals are performed to the point of excluding leisure activities and friendships. Persons affected with this disorder may find it hard to relax, always feeling that time is running out for their activities and that more effort is needed to achieve their goals. They may plan their activities down to the minute—a manifestation of the compulsive tendency to keep control over their environment and to dislike unpredictable things as things they cannot control.
