Sex differences in schizotypal personality in a nonclinical population.
This study tests the hypothesis that normal women will score higher on the more "positive" features of schizotypal personality and normal men will score higher on more "negative" schizotypal features. Two samples (n = 393, 394) were administered the Schizotypal Personality Questionnaire, which contains subscales corresponding to the 9 schizotypal personality traits outlined in the Diagnostic and Statistical Manual of Mental Disorders (rev. 3rd ed.; American Psychiatric Association, 1987). Women scored significantly higher on the positive subscales of Ideas of Reference and Odd Beliefs/Magical Thinking, and men scored significantly higher on the negative subscales of No Close Friends and Constricted Affect. These findings replicated from one sample to another. These results are broadly consistent with previous findings on schizotypal personality and schizophrenia. It is hypothesized that sex differences in schizophrenic symptomatology may in part reflect an exaggeration of normal sex differences in the general population.
