Abstract This study aimed to verify the psychometric properties of the Polish version of the Grit-S questionnaire. Grit is understood here as the perseverance and passion for long-term goals, and it encompasses two dimensions: Consistency of Interest and Perseverance of Effort. The sample comprised N = 270 participants aged 18-34 (M age = 20.79). We performed confirmatory factor analyses to verify the dimensional structure of grit, multi-group confirmatory factor analysis to compare the structure across gender, and correlation analysis to examine external validity (exploring the correlations between grit, procrastination, and well-being). Findings showed satisfactory parameters for Grit-S including: reliability, structural and external validity, and measurement invariance across gender groups. The results support the possibility of using the Grit-S questionnaire in research exploring the predictors of success.
