Perseverance and passion for achieving long-term goals: transcultural adaptation and validation of the Grit-S scale / Perseverancia y pasión por la consecución de objetivos a largo plazo: adaptación transcultural y validación de la escala Grit-S

Abstract The objective of this study was to undertake the transcultural adaptation and validation of the Short Grit Scale (Grit-S) to measure university students’ levels of perseverance and passion for achieving long-term goals. To accomplish this, the Grit-S scale was linguistically and culturally adapted from English to Spanish via the Translation, Review, Adjudication, Pre-testing and Documentation method. After that, the adapted scale was administered to a convenience sample of 1,129 university students comprised of 29.6% males and 70.4% females with a mean age of 21, and finally, its psychometric properties were analysed and compared to the original version. The results reveal acceptable values for the internal consistency of the total scale (α = .71) and outstanding fit indexes for the proposed two-factor structural model (i.e., Consistency of Interest and Perseverance of Effort) (RMSEA = .041, CFI = .96), and the parameters of transcultural adaptation were similar to those in its original version.
