Excoriation which falls under Obsessive-Compulsive and related Disorders refers to:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Skin-picking disorder
Option (1) Hair-pulling disorder — Incorrect. Hair-pulling disorder is trichotillomania, another disorder of the same group, but it is not excoriation.
Option (2) Stealing disorder — Incorrect. A repeated urge to steal things one does not need is an impulse-control problem, not a repetitive act on one’s own body, so it does not belong to the obsessive-compulsive group.
Option (3) Skin-picking disorder — Correct. Besides obsessive-compulsive disorder, the group includes hoarding disorder, trichotillomania (hair-pulling disorder) and excoriation (skin-picking) disorder. In each, the person cannot stop a repeated behaviour even though it affects normal life.
Option (4) Hoarding disorder — Incorrect. Hoarding is a separate disorder of the same group, in which a person keeps collecting things and cannot part with them.
Note: The concept in Option (2), ‘stealing disorder’ (kleptomania), is not in NCERT (2025-26); explained here for the benefit of the students.
