Academic Grit Scale: Psychometric properties and associations with achievement and life satisfaction

After a decade of research, grit has been linked to many adaptive outcomes for adolescents and the development of school-based interventions for promoting adolescents’ grit has been recommended. However, a reconceptualization of grit and its measurement may be vital for future grit research and application. The currently predominant grit assessments may be inappropriate for youth populations, yielding evidence of low psychometric properties and variable criterion-related validity. In a sample of adolescents (N = 757) in sixth to eighth grade, the current study investigated the psychometric properties of the Academic Grit Scale, a novel measure of domain-specific grit. Exploratory and confirmatory factor analyses revealed a single-factor structure of the Academic Grit Scale, and evidence of high internal consistency reliability and construct validity was observed. Results indicated positive associations between academic grit and academic achievement, life satisfaction, and school satisfaction. Furthermore, academic grit demonstrated incremental validity above and beyond that of general grit in association with these outcomes. Implications of the findings are discussed, including the potential to inform applied practices in schools and future empirical investigations.
