Which item is explicitly excluded from the diagnostic criteria for Schizotypal Disorder?

• A. Delusions of reference
• B. Ideas of reference
• C. Odd beliefs
• D. Social anxiety

Answer: (A)

Delusions of reference are not part of the diagnostic criteria for schizotypal personality disorder. In schizotypal PD, people may have ideas of reference—believing that ordinary events have personal significance—without forming fixed, delusional beliefs. The criteria include ideas of reference, odd beliefs or magical thinking, unusual perceptual experiences, suspiciousness, and excessive social anxiety, among others, but not delusions of reference. A delusion of reference would cross into a psychotic disorder like schizophrenia, whereas schizotypal PD features a spectrum of odd beliefs and perceptual distortions without full-blown delusions. So, delusions of reference are explicitly excluded.
