Abstract
Grit, defined as "perseverance and passion for long-term goals", is a known personality trait that successfully predicts high performance in various fields. In spite of extant evidence of the effectiveness of grit, research has not yet clarified the relationship between grit and conscientiousness, a highly correlated personality trait. In this study(N = 355), we examined the effect of grit and conscientiousness on academic achievement, mediated by self-determination motivation. As a result, grit and conscientiousness both predicted academic performance, and intrinsic motivation mediated these relationships. However, conscientiousness no longer related with motivation and academic achievement when grit was controlled for, whereas grit maintained its relationship with motivation and achievement even when conscientiousness was controlled. This result indicates that although the two psychological concepts overlap to some extent, grit has a unique motivational and behavioral effect that distinguishes it from conscientiousness. The present study expands the current understanding of grit with its comparison between grit and conscientiousness. We suggest future research ought refine the grit scale to establish its discriminant validity.
