Resilience in Iranian adolescents during the COVID-19 pandemic: Psychometric Evaluation of the Connor-Davidson Resilience Scale.

Background: Resilience is a measure of the ability to cope with stress and the accurate measurement of it is critical. This study aimed to translate and evaluate the psychometric properties of the Connor-Davidson Resilience Scale in Iranian adolescents during the Coronavirus Disease (COVID-19) pandemic.Methods: In this cross-sectional study, after the scale translation, the content and construct validity were assessed using exploratory and confirmatory factor analysis. Moreover, internal consistency, composite reliability, and invariance measurement were evaluated.Results: The content validity ratio was greater than 0.49, and the modified kappa coefficient for all items was higher than 0.6. With exploratory factor analysis, two factors were extracted consisting of 16 items and explaining 43% of the total variance. The results of confirmatory factor analysis indicated a good fit for the model. Cronbach's alpha and composite reliability for both factors were greater than 0.7. Although there is no significant difference (p = 0.09) in the average resilience of adolescents in different provinces, boys (42.64 ± 10.90) had a significantly (p < 0.001) higher resilience score than girls (40.10 ± 11.92).Conclusion: The study results showed that the Persian 16-item version of the Connor-Davidson Resilience Scale has acceptable reliability and validity in the Iranian adolescent population.
