Excoriation Disorder was newly added to DSM-5 due to evidence of diagnostic validity. Which statement best describes this status?

• A. It existed in DSM-IV and was removed
• B. It was newly added to DSM-5 with strong evidence for validity
• C. It is now considered a subtype of Obsessive-Compulsive Disorder
• D. It is categorized as a sleep disorder

Answer: (B)

Excoriation Disorder was added to DSM-5 because research demonstrated it could be reliably diagnosed and has meaningful, distinct clinical features that justify its own category. Recurrent skin picking leads to tissue damage, distress, and impairment, and it often shares OCD‑like features such as intrusive urges and repetitive behavior, yet it remains a distinct condition. This combination of reliability and validity evidence supported its placement within the obsessive-compulsive and related disorders group in DSM-5. It did not exist in DSM-IV and was not removed from the manual, it is not simply a subtype of OCD, and it is not classified as a sleep disorder.
