History and Mental Status Examination
Individuals with obsessive-compulsive personality disorder are perfectionists. They require order and control in every dimension of their lives.

They are cold and rigid in relationships and make frequent moral judgments; devotion to work often replaces intimacy. They are serious and plodding; even recreation becomes a sober task
