Obsessive-compulsive personality disorder (OCPD) is unhelpfully named, since it is not particularly closely related to the better known obsessive-compulsive disorder (OCD). It does not tend to co-occur with obsessive-compulsive disorder, or even run in the same families. Obsessive-compulsive disorder is an anxiety disorder, in which the sufferer feels compelled to repeat particular thoughts or actions, such as checking or hand-washing. As an anxious condition, it belongs to the same family as depression and generalized anxiety disorder, and thus is related to high Neuroticism and responds to some extent to serotonergic antidepressant medications. Some people have even seen obsessive-compulsive disorder as a low Conscientiousness problem, since the affected individual cannot inhibit the checking or washing response in rather the same manner as the alcoholic cannot inhibit his desire to drink. Whether this is the right characterization or not, it is clear that OCPD is a very different type of problem.16 What, then, does OCPD entail? Psychiatrists define it as ‘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’.
