Psychometric properties of two measures for the assessment of schizotypy in adolescents
چکیده انگلیسی

The purpose of this study was to examine the psychometric properties of the Thinking and Perceptual Style Questionnaire (TPSQ) and the Multidimensional Schizotypal Traits Questionnaire-Reduced (MSTQ-R) in non-clinical adolescents. The final sample consisted of 991 participants with a mean age of 14.7 years (S.D. = 1.8). The internal consistency of the TPSQ subscales ranged from 0.77 to 0.89, and that of the MSTQ-R subscales ranged from 0.62 to 0.81. Construct validity analysis from the TPSQ subscales showed a three-dimensional solution based on the factors social disorganisation, aberrant processing and anhedonia. For its part, factor analysis of the MSTQ-R also showed a three-dimensional solution based on the factors: positive symptoms, negative symptoms and impulsive-nonconformity. The TPSQ and MSTQ-R appear to have good psychometric properties and to be useful instruments for the measurement of schizotypy in adolescence. Moreover, the factor structure of these measures resembles that seen in young adult samples and provides further empirical evidence of the multidimensional structure of the instruments that we use to measure the complex schizotypy construct. Future research should explore in more depth the psychometric properties of these self-report instruments and improve our understanding of schizotypy in adolescents.
