Schizotypalism affects about what percent of people?

• A. 1%
• B. 3%
• C. 5%
• D. 10%

Answer: (B)

Schizotypal personality disorder has a relatively low prevalence in the general population, with about three in every hundred people meeting the criteria. This 3% figure is the most commonly cited estimate in DSM-5 guidance and major epidemiological studies. While studies vary a bit, ranging from less than 1% to around 4%, 3% sits in the middle and is the figure exam questions typically use. The other options—1%, 5%, or 10%—are outside the usual prevalence range for this condition.
