Psychometric properties of the Grit-O and Grit-S scales in university students in Metropolitan Lima

Abstract

Grit is a construct defined by the perseverance and passion of individuals to achieve long-term goals. This construct is measured through the Grit-O (full version of 12 items) and Grit-S (reduced version of 8 items) scales. items). The purpose of this article was to carry out an analysis of the psychometric properties of Grit-O and Grit-S in young university students from Metropolitan Lima. The sample with which we worked were 328 young students from 18 to 29 years old. An analysis of items of both scales was performed, where the Grit-O yielded adequate values in 10 items, while in 2 items they were lower than expected, this in terms of homogeneity index; compared to the Grit-S, which showed acceptable values in its 8 items. In addition, evidence of validity based on internal structure was performed, evidencing the following results: (χ²/gl= 2,36; GFI= 0,98; CFI= 0,96; TLI= 0,95; NFI= 0,96; RMSEA= 0,05; SRMR= 0,05) for Grit-O and χ²/gl= 2,0; GFI= 0,99; CFI= 0,99; TLI= 0,98; NFI= 0,98; RMSEA= 0,05; SRMR= 0,03) for the Grit-S. Similarly, a factorial invariance according to sex was performed, showing that there are no differences when applying the instrument in men and women. As for its reliability, α= 0,72, ω= 0,79 (Grit-O) and α= 0,80, ω= 0,81 (Grit-S) were obtained. Finally, it was evidenced that it correlates with the academic commitment scale (UWESS-9) and dispositional optimism (LOT-R). Concluding that both scales have good psychometric properties, however, the Grit-S shows better statistical adjustments.
