Adolescent students’ grit: Do parents’ grit and educational expectations matter?

Despite the widespread enthusiasm towards grit, little attention has been paid to how stable grit remains over time and what contextual factors can predict longitudinal changes in grit. The present study investigated adolescent students' grit and its change over one year. We employed nationally representative longitudinal data from a sample of Korean adolescent students (N = 2,590) and their parents (N = 2,590). Specifically, we evaluated the temporal stability of student grit, parent grit and educational expectations as determinants of student grit, and the relative importance of student grit in predicting academic achievement compared to academic self-concept. Results of autoregressive cross-lagged modeling revealed that grit was fairly stable over one year. In addition, parents' grit and educational expectations for students' educational attainment emerged as significant predictors of longitudinal changes in students' grit. Finally, when students' academic self-concept was controlled, students' grit was not predictive of their academic achievement. Implications and areas of future research are presented and discussed.
