Step 1: Understanding the Concept:
The question asks to identify which of the listed conditions are classified under the "Anxiety Disorders" chapter in the DSM-5.
Step 2: Detailed Explanation:
Let's analyze each option based on DSM-5 classification:
A. Depression: Major Depressive Disorder is the primary diagnosis in the "Depressive Disorders" chapter. It is not an anxiety disorder.
B. Social Phobia: In the DSM-5, this is officially renamed "Social Anxiety Disorder." It is a core diagnosis within the "Anxiety Disorders" chapter.
C. Panic disorder: This is a key diagnosis within the "Anxiety Disorders" chapter, characterized by recurrent, unexpected panic attacks.
D. Generalized anxiety disorder (GAD): This is another primary diagnosis within the "Anxiety Disorders" chapter, characterized by excessive and persistent worry.
Therefore, Social Phobia, Panic disorder, and Generalized anxiety disorder are all part of the anxiety disorders category.
Step 3: Final Answer:
The correct combination is B, C, and D only.
