Schizotypal personality disorder has a higher prevalence among which group?

• A. It is most common in women
• B. It is more common in biological relatives of schizophrenics
• C. It is exclusively in children
• D. It is rare in men

Answer: (B)

Schizotypal personality disorder shows a familial pattern tied to schizophrenia, meaning it occurs more often in people who are biologically related to someone with schizophrenia. This reflects a shared genetic or familial vulnerability along the schizophrenia spectrum, so the disorder is more common among first-degree relatives of those with schizophrenia than in the general population.

That’s why the statement about being more common in biological relatives is the best descriptor. It isn’t primarily about gender, age, or this condition being limited to children or rare in any sex, so those other options don’t fit the pattern as well.
