Question

In DSM-5, Obsessive-compulsive disorder has been classified in:

• A. Anxiety disorders
• B. Mood disorders
• C. Dissociative disorders
• D. Obsessive-compulsive and related disorders

Hint:

One of the key changes to remember for the DSM-5 is the creation of new chapters for disorders that were previously grouped elsewhere. The creation of the "Obsessive-Compulsive and Related Disorders" and "Trauma- and Stressor-Related Disorders" chapters, separating them from Anxiety Disorders, is a major example.

Answer 1

The Correct Option is D

Step 1: Concept Clarification:
The query pertains to the categorization of Obsessive-Compulsive Disorder (OCD) within the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Step 2: In-depth Analysis:
A significant alteration from the preceding edition (DSM-IV-TR) to the DSM-5 involved the reclassification of OCD. Previously, under the DSM-IV-TR, OCD was grouped within "Anxiety Disorders." However, substantial evidence indicated that OCD possesses distinct neurobiological foundations and symptomatic characteristics separate from other anxiety disorders. Consequently, the DSM-5 established a novel, independent chapter dedicated to it, titled "Obsessive-Compulsive and Related Disorders." This chapter also encompasses conditions such as Body Dysmorphic Disorder, Hoarding Disorder, and Trichotillomania (hair-pulling disorder).
Step 3: Conclusive Response:
Within the DSM-5, OCD is classified in its dedicated category, "Obsessive-Compulsive and Related Disorders."
