title: Schizotypal Personality Questionnaire-Brief: factor structure and convergent validity in inpatient adolescents.
abstract: We examined the internal consistency, factor structure, and validity of the Schizotypal Personality Questionnaire-Brief (SPQ-B). Two hundred thirty-seven psychiatrically hospitalized adolescents were administered the SPQ-B and a battery of well-established self-report instruments. The SPQ-B demonstrated adequate internal consistency. Exploratory factor analysis provided mixed support for the SPQ-B 3-factor structure of interpersonal deficits, cognitive-perceptual deficits, and disorganization. The Interpersonal and Cognitive-Perceptual subscales demonstrated convergent and discriminant relationships with other measures of interpersonal impairment and cognitive abnormalities. We concluded that the SPQ-B is a promising measure for evaluating schizotypal personality disorder features, specifically interpersonal and cognitive-perceptual deficits, with adolescent psychiatric inpatients.
