Validación cruzada del modelo triárquico subyacente al STAT (Sternberg Triarchic Abilities Test –nivel–H) en una muestra española y norteamericana

Abstract

Following a strategy of multi-sample analysis, we compare different theoretical models regarding the structure underlying the STAT (Sternberg Triarchic Abilities Test), level H, by means of the Confirmatory Factorial Analysis in two samples of participants, Spanish and Northamerican. The comparison of the different models is done using the hierarchical confirmatory factorial analysis with a strategy of comparing nestled models. These models related to the structure underlying the STAT belong to different assumptions. The first one is related to a unidimensional concept of intelligence that postulates the existence of a single factor. The second model is related to the traditional factorial concept in which content factors are crucial. And we also used a triarchic model that postulates the existence of three intellectual factors relatively independent: the analytical, practical, and creative factors. The results are obtained from a sample of 240 Spanish students of Bachillerato, and 326 American high school students. They show that the model which better suits the empirical data is the one based on a triarchic concept of intelligence.
