Propiedades Psicométricas de la Escala WISC-V en Escolares Rurales Chilenos

Abstract

In Chile, the Wechsler Intelligence Scale for children (WISC-R and WISC-III) has been used massively in the urban and rural school populations, without having studies on its psychometric adjustment in the rural group. The present study explored the psychometric properties (evidence of internal structure validity and internal consistency) of the WISC-V in rural schoolchildren. An intentional non-probabilistic sample of 160 students between 6 and 16 years of age belonging to 4 educational establishments in the Maule region and 9 in La Araucanía, was evaluated. Three factorial models composed of 7, 10 and 15 subtests were tested. The results of the confirmatory factor analysis show adequate fit indices in these three models, consistent with the theoretical proposal by the author of the scale and especially better for the models with 7 and 10 primary subtests. Regarding reliability, adequate levels of internal consistency are observed, ranging between acceptable and good, in all the subtests in which this indicator could be calculated. Based on these results and for interpretive purposes, the use of the model composed of 10 primary subtests and the CIT as an estimator of general cognitive functioning in the Chilean rural population is recommended.
