Psychometric properties of the Arabic version of the Oviedo Grit Scale (A-EGO) in non-clinical adults from the general population

BACKGROUND: Given the high clinical utility of grit, and the lack of measures that assess this construct among the Arabic-speaking populations, we propose to examine the psychometric properties of an Arabic translation of the Oviedo Grit Scale (A-EGO) in terms of internal consistency, factor structure, convergent validity, and measurement invariance in a sample of Lebanese adults from the general population. METHODS: We performed a cross-sectional, online study among 575 participants from the Lebanese general population (mean age = 26.28 years [SD: 8.83], 72.7% females). The unidimensional factorial structure of the A-EGO was analyzed by confirmatory factor analysis (CFA) using the MPlus8 program. The mean and variance adjusted weighted least squares (WLSMV) was used as the estimation method. The reliability of the scores, the evidence of validity in terms of measurement invariance and correlation with other variables were analyzed. RESULTS: The present results show that the 10 items of the A-EGO loaded on one factor. The internal consistency was excellent in our sample, as evidenced by a Cronbach’s alpha value of .93. Multi-group confirmatory factor analyses demonstrated invariance across gender, governorate, and marital status at the configural, metric and scalar levels. Additionally, A-EGO scores showed moderate and positive correlations with self-control (r = .442), conscientiousness (r = .478), and productiveness facet (r = .506), supporting the convergent validity of the A-EGO. CONCLUSION: Our findings indicate that the A-EGO has good psychometric properties and can be recommended for the assessment of grit among the broader Arabic-speaking people worldwide. Making this scale available in the Arabic language will hopefully foster research in this area in Arab countries.
