“…Callaway et al [67] also reported that both scales constitute one of the four super-ordinate dimensions of the SPQ-Short version. Finally, difficulties with the "constricted affect" sub-scale also emerged in the Fonseca-Pedrero et al [30] study, where this sub-scale could not be replicated, when EFA analysis was employed to examine the factorial structure of the SPQ.…”

“…However, the vast majority of these studies have examined the structure of the SPQ at a scale level (second-order models). Only one study has examined the dimensional structure of the SPQ at the item level, and found, by means of CFA, marginally acceptable fit indices for the nine-factor model [30].…”

“…So far, very few studies have examined the factorial structure of the SPQ at the item level [e.g. 14,29], with only one examining it within the CFA framework [30]. This examination is considered as very important, since it would provide significant evidence regarding the nomological structure of the instrument.…”

“…Estos resultados son convergentes con estudios realizados previamente en población adolescente y adulta (Fonseca-Pedrero et al, 2014;Fossati et al, 2003;Wuthrich y Bates, 2006) y resaltan el paralelismo fenotípico con los encontrado en pacientes con esquizofrenia. Por ejemplo, Fonseca-Pedrero et al (2009), utilizando el SPQ-B en una muestra representativa de adolescentes españoles, encontraron que el modelo tridimensional de Raine et al (1994), fue el que mejores índices de bondad de ajuste mostró.…”

“…Concretamente, utilizando el SPQ o SPQ-B, el modelo tridimensional de Raine et al (1994) ha sido ampliamente replicado, y se muestra consistente a través de los estudios (Fonseca-Pedrero, Paino, Lemos-Giráldez, Sierra-Baigrie y Fossati, Raine, Carretta, Leonardi y Maffei, 2003;Wuthrich y Bates, 2006). Dicho modelo se concreta en tres dimensiones de esquizotipia, a saber, Positiva (Cognitivo-Perceptual), Interpersonal (Negativa) y de Desorganización; no obstante, es igualmente cierto que otros estudios han encontrados dos, tres, cuatro o incluso más dimensiones (Cohen, Matthews, Najolia y Brown, 2010;Compton, Goulding, Bakeman y McClure-Tone, 2009;Fonseca-Pedrero et al, 2014). Utilizando el SPQ-C, se ha hallado que el modelo tridimensional de Raine et al (1994) fue el que mejores índices de bondad de ajuste presentó en comparación con el resto de los modelos hipotéticos sometidos a prueba .…”

Resumen: Las experiencias esquizotípicas son consideradas como la expresión conductual de vulnerabilidad latente a los trastornos del espectro esquizofrénico. El objetivo de esta investigación fue analizar la calidad psicométrica del Schizotypal Personality Questionnarie-Child (SPQ-C) en adolescentes no clínicos. La muestra final la formaron un total de 508 participantes, 208 varones, con una media de edad de 13.9 años (DT = 1.7). Los resultados mostraron que las experiencias esquizotípicas son comunes entre la población adolescente. Los modelos dimensionales hipotetizados sometidos a prueba, mediante análisis factorial confirmatorio, indicaron que el modelo tridimensional fue el que mejores índices de ajuste presentó en comparación con los modelos competentes. El coeficiente alfa de Cronbach para la puntuación total del SPQ-C fue .90. Las dimensiones del SPQ-C mostraron correlaciones estadísticamente significativas con otros autoinformes que valoraban sintomatología emocional y comportamental y estrés percibido. Ningún elemento del SPQ-C mostró funcionamiento diferencial del ítem para el factor sexo. El SPQ-C presentó un adecuado comportamiento psicométrico en esta muestra. Asimismo, la esquizotipia es un constructo de naturaleza multidimensional que puede ser evaluado de forma precisa en población adolescente con la finalidad de mejorar las estrategias de detección temprana en el campo de los trastornos mentales graves. Palabras clave: Esquizotipia; esquizotípica; validación; fiabilidad; adolescentes; SPQ.Title: Schizotypal experiences in adolescence: Psychometric properties of Schizotypal Personality Questionnarie-Child Abstract: 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. Key words: Schizotypy; schizotypal; validation; reliability; adolescents; SPQ.

Objective To obtain more precise and rich information from the measurements for schizotypal personality disorder (SPD), a cutting‐edge psychometric theory called diagnostic classification models (DCMs) was first employed in the present study to develop a diagnostic classification version of the Schizotypal Personality Questionnaire (DC‐SPQ) based on the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. Methods Under the framework of DCMs, 980 college students were recruited to calibrate item parameters of the Schizotypal Personality Questionnaire. Items that fit the psychometric characteristic would be selected to compose the DC‐SPQ, prior to an analysis of its indexes. Results Results showed that the DC‐SPQ had high reliability and validity in both the classical test theory and DCMs, in addition to showing a sensitivity of 0.921 and a specificity of 0.841 with area under receiver operating characteristic curve = 0.936. Meanwhile, the four‐factor model proposed adequately fits with the data. More importantly, the DC‐SPQ provides not only the general‐level information similar to traditional questionnaires but also the symptom‐level information with the posterior probability, which provides an insight into delivering the individual‐specific intervention that is tailor made to schizotypal personality disorder. Conclusions This study demonstrates that the DC‐SPQ is very valuable for psychometric detection in that it can clarify the symptom being measured and provide more reasonable estimates.
