Psychometric Properties of the Chilean Version of the Oviedo Grit Scale

Abstract

Grit is a non-cognitive variable that helps predict important variables in people’s lives, such as academic, sport, and work performance, physical and mental health, and subjective well-being. However, there are few instruments measuring grit in the Chilean context. The aim of this study is to contribute new evidence of validity of the Oviedo Grit Scale (Escala Grit de Oviedo; EGO) through its adaptation to a Chilean sample. A sample of 359 Chilean participants was used (Myears= 41.28; SDyears= 11.09; 69.4% women), from the 16 regions that make up the Chilean territory. The unidimensionality of the EGO was confirmed in the Chilean context, also showing scalar invariance in terms of sex. The reliability of the scores on the EGO was excellent (α = .92; ω = .92), showing high correlations with grit, measured through the Grit-S scale (r = .577), self-control (r = .500), self-efficacy (r = .809), and productiveness (r = .679). In addition, the EGO showed statistically significant differences in terms of age. It is concluded that it is a reliable, valid, and brief scale to evaluate grit, and thus this construct can be studied in relation to important variables that affect people’s lives.
