GENDER DIFFERENCES IN SCHIZOTYPIC FEATURES IN A LARGE-SAMPLE OF YOUNG-ADULTS

Research with self-report measures of schizotypic or psychosis-prone features in nonclinical populations suggests that, similarly to schizophrenic populations, males score higher on more ''negative'' schizotypic features and females score higher on more ''positive'' schizotypic features. Rie administered the Schizotypal Personality Questionnaire and the Chapman Scales of Psychosis Proneness-impulsivity/nonconformity, magical ideation, perceptual aberration, physical anhedonia, and social anhedonia-to a large, nonclinical, young adult sample (N = 1179: 453 males and 726 females). Results indicated increased negative symptomatology in males compared with females, but not increased positive symptomatology in females compared with males. Findings on Schizotypal Personality Questionnaire factors suggested that interpersonal deficits differed by gender as well. Finally, a measure of impulsive behavior and nonconformity not typically associated with negative symptomatology indicated gender differences not predicted by a negative/positive dichotomy.
