Obsessive-compulsive personality disorder
Obsessive-compulsive personality disorder is a personality disorder that is often confused with obsessive-compulsive disorder. They are actually two quite different disorders. Those who are suffering from the personality disorder do not generally feel the need to perform repetitive ritualistic actions (such as excessive hand-washing) that characterizes OCD. Instead, theirs is a skewed philosophy of most areas of their lives. They tend to stress perfectionism above all else, and feel anxiety when they perceive that things aren't "right."They are generally inflexible, conforming to a set of rigid rules and procedures that stress perfectionism and orderliness. They may hoard money, expect that the home will be kept perfectly organized, or be anxious about delegating tasks for fear that they won't be completed correctly. There are few moral grey areas for a person with OCPD; actions and beliefs are either completely right, or absolutely wrong. As might be expected, interpersonal relationships are difficult because of the excessive demands placed on friends, romantic partners, and children.
Therapy is difficult, and involves persuading the OCPD sufferer to accept that there are valid viewpoints that may contrast with their own, and that there may be many "right" ways to accomplish most tasks.
