Abstract

The Wisconsin Schizotypy Scales are among the most widely used instruments for the assessment of psychosis proneness. The main goal of the present work was to study the dimensional structure underlying the Revised Physical Anhedonia Scale (RPhA), the Revised Social Anhedonia Scale (RSAS), the Magical Ideation Scale (MIS) and the Perceptual Aberration Scale (PAS). It was also explored whether the dimensions underlying these scales were invariant across gender and age. The sample was made up of 710 university students with a mean age of 19.8 years (SD = 1.9). The results showed that the dimensional structure of the Wisconsin scales was similar to that found in previous studies, displaying a Positive dimension and a Negative dimension, the Social Anhedonia Scale being related to both dimensions. Moreover, the factor structure of the schizotypy scales was found to be invariant across participants' gender and age.

Las escalas de esquizotipia de Wisconsin son unos de los instrumentos de medida más utilizados para la evaluación de la propensión a la psicosis. El principal objetivo del presente trabajo fue estudiar la estructura dimensional subyacente a la Revised Physical Anhedonia Scale (RPhA), la Revised Social Anhedonia Scale (RSAS), la Magical Ideation Scale (MIS) y la Perceptual Aberration Scale (PAS). Asimismo, también se exploró si las dimensiones de la esquizotipia se mostraban invariantes en función del sexo y la edad de los participantes. La muestra final la formaron 710 universitarios con una media de edad de 19,8 años (DT = 1.9). Los resultados mostraron que la estructura dimensional de las escalas de Wisconsin fue similar a la encontrada en estudios previos, mostrando una dimensión Positiva y una dimensión Negativa de la esquizotipia, en donde la faceta anhedonia social se relacionaba con ambas dimensiones. Más aun, la estructura factorial de las escalas de esquizotipia se mostró invariante en función del sexo y la edad de los participantes.
