All of the following describes obsessive-compulsive personality disorder except

A. Worry about health despite no symptoms. This describes illness anxiety disorder (formerly hypochondriasis), where individuals have an excessive fear of having a serious illness despite minimal or no physical symptoms. Unlike factitious disorder, these individuals are not fabricating symptoms but are genuinely convinced they are sick.

B. Normal voluntary and sensory dysfunction. This does not describe any recognized psychiatric disorder. However, conversion disorder (functional neurological symptom disorder) involves involuntary neurological symptoms (e.g., paralysis, blindness) without a medical cause, whereas factitious disorder involves intentional symptom fabrication.

C. Worry is out of proportion to the symptoms. This is characteristic of somatic symptom disorder (SSD), where individuals have excessive concern and distress over real but often minor physical symptoms. Unlike factitious disorder, their symptoms are not deliberately produced or exaggerated for attention.

D. Deliberate exaggeration and fabricated symptoms. Factitious disorder (formerly Munchausen syndrome) involves intentionally faking, exaggerating, or inducing medical symptoms to assume the "sick role". Unlike malingering (which is done for external rewards like financial gain), factitious disorder is driven by an internal psychological need for medical attention.

A. Only engages in solitary activities. Individuals with schizoid personality disorder (SPD) prefer solitary activities and show little interest in social interactions. They are emotionally detached and lack the desire for close relationships, including friendships and romantic partnerships.

B. Dislikes criticism. While people with SPD may be indifferent to praise or criticism, they are not particularly sensitive to it. Unlike avoidant personality disorder, where individuals avoid social interactions due to fear of rejection, those with SPD are emotionally detached and often indifferent to others' opinions.

C. Always wants to be center of attention. This describes histrionic personality disorder (HPD), not schizoid personality disorder. Individuals with HPD seek constant attention, approval, and validation, whereas those with SPD prefer to remain isolated and avoid social engagement.

D. Affective flattening. Affective flattening (emotional coldness or limited emotional expression) is a key feature of SPD. Individuals display minimal facial expressions, monotone speech, and reduced nonverbal communication, contributing to their perceived social aloofness.
