Which of the following is NOT a type of anxiety disorder?

• A. Social anxiety disorder
• B. Phobias
• C. Separation anxiety disorder
• D. Schizophrenia

Answer: (D)

Anxiety disorders are defined by patterns of excessive fear or worry that disrupt daily life. Among the options, the first three fit that idea: social anxiety disorder involves intense fear of social or performance situations, phobias are irrational fears of specific objects or situations, and separation anxiety disorder is excessive worry about being apart from home or caregivers. Schizophrenia, on the other hand, is a psychotic disorder characterized by delusions, hallucinations, disorganized thinking, and other cognitive changes rather than primarily by fear or anxiety. So the one that is not an anxiety disorder is schizophrenia, because its core features are distinct from anxiety-based problems.
