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.

Psychometric Assessment of the Short Grit Scale (Grit-S) using the Rasch Model in a Malaysian Polytechnic Students’ Sample

“…The items were found to have good validity and reliability considering the items and individuals. It is interesting to note that most items met the assumptions of modern test theory in this study using the Rasch model and also meeting classical test theory as in previous studies (Ezaty et al, 2019;González-Bernal et al, 2022;Postigo et al, 2023). Surprisingly, few differences were found in the item assessment for both measurement theories, even though the nature was different.…”

“…Cultivate courage in pupils so they can endure, even in the face of hardship, until the goal is reached (Yazon et al, 2021). Several past grit studies have been conducted concerning assessing psychometric characteristics (Ezaty et al, 2019;González-Bernal et al, 2022;Postigo et al, 2023). However, their research focuses more on psychometric assessment using classical test theory than modern theories such as the Rasch model.…”

“…The Short Grit Scale or Grit-S is a helpful scale for determining grit (A. L. Duckworth & Quinn, 2009). Previous international research from Malaysia (González-Bernal et al, 2022;Postigo et al, 2023) has only dealt with the psychometrics of Grit-S using classical test theory compared to the modern approach for Rasch. Areepattamannil and Khine (2018) used Rasch analysis among 777 adolescents hailing from Arab states of the Persian Gulf.…”

“…As a result, the grit concept and term become too common and complicate the process of developing grit instruments in special clusters. There are several studies on the measurement of grit through the development of instruments via adaptation (Chisholm-Burns et al, 2019;Duckworth & Quinn, 2009;González-Bernal et al, 2022;Schmidt et al, 2019) or psychometric testing studies (Postigo et al, 2023).…”
