![]() ![]() 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. Hence, care should be taken when using the Grit-S in cross-cultural and cross-age studies as scores from different nationalities and age groups may not be directly comparable.Grit, the passion and perseverance for long-term goals, has received attention from personality psychologists because it predicts success and academic achievement. However, results show the Grit-S to be non-invariant across different nationalities and age groups. Moreover, the present study found support for the multidimensionality of the Grit-S, highlighting the importance of its subscales. Results support the Grit-S as a valid and reliable measurement instrument of grit, providing evidence for its factorial validity, internal consistency, convergent and criterion validity. ![]() The present study investigated the psychometric properties of the Grit-S in an international sample (N = 272) by means of confirmatory factor analysis and correlational analysis using Mplus and SPSS. While research has demonstrated the importance of grit, the validity and reliability of the Grit-S remain disputed. Grit can be assessed by means of the Grit-S, an 8-item self-report questionnaire which comprises two subscales representing consistency of interest and perseverance of effort. Defined as passion and perseverance for long-term goals, grit plays an important role in numerous areas of life from academic achievement and career endorsement to athleticism and mental health. A noncognitive trait which attracted much attention during more recent years is grit. The psychometric properties of the short Grit Scale (Grit-S) within an international context.ĭuring the past decades, noncognitive traits and their contributions to a satisfied and fulfilled life have been extensively studied. ![]()
