Obsessive Compulsive Personality Disorder
A pervasive pattern of preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency, beginning by early adulthood and present in a variety of contexts, as indicated by four (or more) of the following:
 is preoccupied with details, rules, lists, order, organization, or schedules to the extent that the major point of the activity is lost.
 shows perfectionism that interferes with task completion (e.g., is unable to complete a project because his or her own overly strict standards are not met)
 is excessively devoted to work and productivity to the exclusion of leisure activities and friendships (not accounted for by obvious economic necessity)
 is overconscientious, scrupulous, and inflexible about matters of morality, ethics, or values (not accounted for by cultural or religious identification)
 is unable to discard worn-out or worthless objects even when they have no sentimental value
 is reluctant to delegate tasks or to work with others unless they submit to exactly his or her way of doing things
 adopts a miserly spending style toward both self and others; money is viewed as something to be hoarded for future catastrophes
 shows rigidity and stubbornness
