Análisis de la estructura factorial del stai-t en una muestra de deportistas brasileros

Abstract

This study aimed to examine the internal structure of the State-Trait Anxiety Inventory (STAI-T) in a sample of Brazilian athletes. Participants were 179 subjects practicing five different sports modalities, aged between 14 and 58 years (M = 21.04; SD = 4.21). The inventory assesses anxiety as state and trait, but in this study only the trait anxiety scale was used which is composed of 20 items arranged in a four-point Likert scale. Results of the confirmatory factor analysis indicated the items were not properly adjusted to the instrument’s original model. This exploratory factor analysis indicated the existence of two factors that explained 33% of the variance. These factors were called present anxiety and absent anxiety, with reliability coefficients of 0.82 and 0.72 respectively.
