Obsessive-compulsive personality disorder (OCPD), or anankastic personality disorder, is a personality disorder that is characterized by a general psychological inflexibility, rigid conformity to rules and procedures, perfectionism, and excessive orderliness.
Obsessive-compulsive personality disorder (OCPD) is often confused with obsessive-compulsive disorder (OCD).
While the names sound similar, these are two quite different disorders.
Those who are suffering from OCPD do not generally feel the need to repeatedly perform ritualistic actions (such as excessive hand-washing), while this is a common symptom of OCD.
Instead, people with OCPD tend to stress perfectionism above all else, and feel anxious when they perceive that things are not "right." People with OCPD may hoard money, keep their home perfectly organized, or be anxious about delegating tasks for fear that they won't be completed correctly.
There are few moral gray 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.
