The purpose of this article is to develop and validate the Korean Version of Grit Scale(K-GRIT), making up for the issues of factor structure and definition of Grit in the original scale(GRIT-O). In study 1 for the statistical issue, negative statements of GRIT-O were changed positively and then confirmatory factor analysis was conducted. The results demonstrated that two-factor model of the scale fit better than one-factor model as in GRIT-O. Moreover the enhanced version of the scale with positively changed items showed better fit than the original one. In study 2, 26 preliminary items were developed which consist of 12 items of GRIT-O and 14 new items that describe how the specific long-term goal is meaningful and enjoyable for oneself. As a result of exploratory factor analysis of the data of 278 college students, 20 items were finally chosen and three factors of ‘effort-persistence’, ‘passion-meaning’, ‘passion-enthusiasm’ were identified. The result of confirmatory factor analysis using the other data of 278 students showed that the three factor model fit was fair. The results of validity analysis and nomological network consisted of grit, conscientiousness, growth mindset, mental wellbeing, life satisfaction and academic achievement suggest that K-GRIT would be a reliable scale for measuring grit. The implications and limitations of the study were discussed.
