FONSECA-PEDRERO, Eduardo et al. Schizotypal experiences in adolescence: psychometric properties of Schizotypal Personality Questionnarie-Child. Anal. Psicol. [online]. 2015, vol.31, n.2, pp.414-421. ISSN 1695-2294.  https://dx.doi.org/10.6018/analesps.31.2.167431.

Schizotypal experiences are considered as the behavioral expression of latent vulnerability to the schizophrenia-spectrum disorders. The main goal was to analyze the psychometric quality of Schizotypal Personality Questionnarie-Child (SPQ-C) in non-clinical adolescents. The final sample was comprised of a total of 508 participants, 208 were male, with a mean age of 13.9 years (SD = 1.7). The results showed that schizotypal traits are common among adolescents. Hypothesized dimensional models tested by confirmatory factor analysis, indicated the three-dimensional model was the best fit indices presented in comparison with competing models. Cronbach's alpha coefficient for the total score was .90. The dimensions of the SPQ-C showed significant correlations with self-reports that assessed emotional and behavioral problems and perceived stress. No items on SPQ-C showed differential item functioning by gender. The SPQ-C scores showed adequate psychometric properties. Also, schizotypy is a multidimensional construct that can be accurately assessed in adolescents in order to improve early detection strategies in the field of severe mental disorders.
