Difficulty: MediumPersonality Disorders

A 36-year-old man, who works as a software quality assurance manager, comes to his primary care physician for a routine physical examination. He hands the physician a neatly bound, color-coded 20-page document detailing his daily blood pressure readings, caloric intake, and sleep duration for the past six months. He complains of chronic fatigue, stating that he often stays awake until 3:00 AM reviewing his subordinates' code. He says, "If I do not check every single line myself, they will ruin the product. It is just more efficient if I take over their tasks." He mentions that his wife recently threatened to separate from him because he refuses to let her load the dishwasher, arguing she "never follows the optimal spatial configuration." The patient does not believe his behavior is problematic; rather, he is highly frustrated that others fail to meet his exacting standards. He denies experiencing recurrent intrusive thoughts that cause him distress, and he does not perform repetitive physical rituals to neutralize anxiety. Which of the following is the most likely diagnosis?

  1. A
    Obsessive-compulsive disorder
  2. B
    Narcissistic personality disorder
  3. Obsessive-compulsive personality disorderAnswer
  4. D
    Bipolar II disorder
  5. E
    Delusional disorder

Answer

Obsessive-compulsive personality disorder
This patient's presentation is classic for obsessive-compulsive personality disorder (OCPD). The diagnosis is characterized by a pervasive pattern of preoccupation with orderliness, extreme perfectionism, and mental/interpersonal control at the expense of flexibility, openness, and efficiency. Key features exhibited by this patient include an excessive devotion to work (staying up until 3:00 AM), a reluctance to delegate tasks unless others submit exactly to his way of doing things (rewriting code, controlling the dishwasher), and a rigid adherence to tracking data (the 20-page document). Crucially, individuals with OCPD typically view their way of thinking and behaving as normal and beneficial (ego-syntonic), whereas they are often frustrated by the perceived incompetence or lack of organization of others.

Step-by-Step Solution

1
Analyze the patient's pattern of behavior and interpersonal functioning.
The patient shows extreme perfectionism, rigidity, reluctance to delegate tasks (at work and home), and excessive devotion to productivity.
Identifying pervasive behavioral patterns is essential for diagnosing personality disorders.
2
Determine if the symptoms are ego-syntonic or ego-dystonic.
The patient is frustrated by others, not by his own behavior, confirming his symptoms are ego-syntonic.
Ego-syntonic behavior points toward a personality disorder rather than an anxiety disorder.
3
Evaluate for true obsessions and compulsions.
The patient denies intrusive distressing thoughts and neutralizing rituals.
This rules out Obsessive-compulsive disorder (OCD) in favor of Obsessive-compulsive personality disorder (OCPD).

Key Concept

Obsessive-Compulsive Personality Disorder (OCPD) is characterized by an ego-syntonic, pervasive pattern of preoccupation with orderliness, perfectionism, and mental/interpersonal control.
