Grit scale6/14/2023 Similar evidence could be used to study construct overlap between grit and persistence, motivation, or tenacity. ![]() Empirical evidence of construct overlap between grit and self-control could help consolidate those research areas. One of many examples is that both grit and self-control, a conscientiousness facet, involve goal-setting and attainment ( Credé et al., 2017 Duckworth & Gross, 2014 Muenks, Wigfield, Yang, & O’Neal, 2017). Instead of wasting efforts, the decade-long research on the grit construct could be integrated with research on other personality constructs. Jangle fallacies prevent the consolidation of many research efforts in psychology. 60), and that grit may not have incremental prediction on academic performance after accounting for conscientiousness ( Credé et al., 2017). For example, previous research suggests that grit and conscientiousness are highly correlated ( r >. A recent meta-analysis suggests that grit researchers have fallen victim to the jangle fallacy because grit may be a repackaged version of conscientiousness ( Credé et al., 2017). On the other hand, the construct map of grit has also been questioned. Grit has also gained attention as a potential target for interventions because it may be more malleable than intelligence and other cognitive abilities ( Duckworth, Grant, Loew, Oettingen, & Gollwitzer, 2011 Duckworth & Gross, 2014 Eskreis-Winkler et al., 2016 Shechtman, DeBarger, Dornsife, Rosier, & Yarnall, 2013). Additionally, research suggests that grit is related to conscientiousness, self-control, emotional stability, self-efficacy, mental toughness, and positive affect ( Credé, Tynan, & Harms, 2017). For example, grit is associated with positive outcomes like success in work or school ( Duckworth et al., 2007 Duckworth & Quinn, 2009 O’Neal et al., 2016 Strayhorn, 2014) and goal achievement ( Duckworth, Kirby, Tsukayama, Berstein, & Ericsson, 2011 Eskreis-Winkler, Shulman, Beal & Duckworth, 2014). Past research has focused on studying the relations of grit with other constructs. The construct of grit has received attention from personality psychologists because research suggests that it can predict success in education and other areas uniquely over talent or opportunity alone ( Duckworth, Peterson, Matthews, & Kelly, 2007). Finally, we discuss recommendations for the use of the Grit-S based on the theoretical interpretation of the unidimensional factor and our empirical findings. Subscale factors were the result of an item doublet, where two items had high correlated uniquenesses, showed similar item information, and were more likely to exhibit measurement bias. Our results suggest that the Grit-S is essentially unidimensional and that there is construct overlap with the self-control construct. We conducted modern psychometric techniques including parallel analysis, measurement invariance, extrinsic convergent validity, and Item Response Theory models on two American samples. Previous research suggests that the Short Grit Scale (Grit-S) has several psychometric limitations, such as uncertain factor structure within and across populations, uncertainty about reporting total or subscale scores, and different assessment precision at low and high levels on the construct. A precise psychometric representation of grit is needed to understand how the construct is unique and how it overlaps with other constructs. ![]() Grit has also been criticized as simply another measure of self-control or conscientiousness. Grit, the passion and perseverance for long-term goals, has received attention from personality psychologists because it predicts success and academic achievement.
