DSM-5 Case Studies Practice Test

This item hinges on recognizing a pattern of rigid preoccupation with orderliness, perfectionism, and control that reduces flexibility. That description fits Obsessive-Compulsive Personality Disorder, where individuals show a pervasive, long-standing emphasis on rules, details, and getting things exactly right. They may insist on strict schedules and be reluctant to delegate because they want things done their way, often compromising efficiency and adaptability. Importantly, these traits are ego-syntonic—they see their way of functioning as appropriate and may not view it as a problem, even though it interferes with everyday life.

In contrast, the other patterns have different signatures. Histrionic personality involves attention-seeking, dramatic behavior and shallow emotions. Schizoid personality features social detachment and indifference to relationships. Paranoid personality centers on pervasive distrust and suspiciousness.
