Validez Estructural de la Escala Wechsler de Inteligencia para Niños-IV en Estudiantes Indígenas de México

Abstract

In this paper we present evidence about the structural validity of the WISC-IV in a sample of 151 indigenous Yaqui students (Mexico) between the ages of 7 and 8 years old through an analysis of the test's intercorrelations matrix and of an exploratory and confirmatory factor analysis. The analysis of the matrix showed low to moderate correlation coefficients between the tests. The exploratory factor analysis indicated some differences on the model of the four WISC-IV factors. The confirmatory factor analysis supported the hierarchical model of the four first-order factors and a second-order general intelligence factor. This accounted for the greater amount of the common (76.8%) and total variance (35.8%). In conclusion this scale is useful to assess the intelligence of these students in the framework of assessment practices that consider other methods, sources, and the specific characteristics of the context.
