The male in this scenario is obsessed with order and perfection, and most likely has an obsessive compulsive personality disorder (OCPD).
A personality trait is an enduring pattern of behavior exhibited in a wide range of persons, while a personality disorder is a pervasive, inflexible, extreme, maladaptive personality trait causing impaired functioning or subjective distress. The disorders are ego syntonic - the person has limited awareness of disorder. Personality disorders are divided into three clusters: A, B, C. In this scenario, the male has a cluster C personality disorder which is generally characterized by being worried, anxious, fearful, and are associated with anxiety disorders. Specifically, this male has OCPD due to his preoccupation with order, perfectionism, and control; it is typically ego syntonic, whereas obsessive-compulsive disorder (OCD) is ego dystonic.
Ward reviews personality disorders stating that they cannot be caused by a "major psychiatric disorder, a medical disorder, or the effects of a substance." Diagnosis typically occurs over the course of many interactions with the physician. Clues can be seen in patient's style of interaction with and their expectations from the physician.
