A 35-year-old man insists his spouse follow his detailed household rules exactly. He believes his way is correct and becomes angry when others suggest flexibility. He has no intrusive thoughts or rituals. This presentation is most consistent with:

• A Obsessive-compulsive disorder
• B Schizoid personality disorder
• C Autism spectrum disorder
• D Obsessive-compulsive personality disorder ✓

Explanation

The patient's rigid perfectionism, preoccupation with rules, and belief that his way is correct are ego-syntonic features characteristic of OCPD. OCD involves ego-dystonic obsessions and compulsions that the individual recognizes as excessive. Autism involves social communication deficits. Schizoid personality involves emotional detachment, not rule-bound behavior.
