Typology of schizotypy in non-clinical young adults: Psychopathological and personality disorder traits correlates

[摘要] Few typological studies address schizotypy in young adults. Schizotypal traits were assessed on 466 college students using the Schizotypal Personality Questionnaire-Brief (SPQ-B). Other measures evaluated personality traits previously associated with schizotypy (borderline, obsessionnal, and autistic traits), psychopathological symptoms (suicidal ideations, depressive and obsessive-compulsive symptoms) and psychosocial functioning. A factor analysis was first performed on SPQ-B results, leading to four factors: negative schizotypy, positive schizotypy, social anxiety, and reference ideas. Based on these factors, a cluster analysis was conducted, which yielded four clearly distinct groups characterized by Low (non schizotypy), High schizotypy (mixed positive and negative), Positive schizotypy, and Social impairment. Regarding personality disorder traits and psychopathological symptoms, the High schizotypy cluster scored higher than the Positive and the Social impairment groups, which scored higher than the Low cluster. The Positive group had higher levels of interpersonal relationships than in the High and the Social impairment clusters, suggesting that positive schizotypy was associated to benefits such as perceived social relationships. Nevertheless the Positive cluster was also linked to high levels of personality disorder traits and psychopathological symptoms, and to low academic achievement, at levels similar those observed in the Social impairment cluster, confirming an unhealthy side to positive schizotypy.
