During times of crisis, and in particular during the current COVID-19 pandemic, resistance resources, such as resilience, are key to managing the negative impacts of the crisis. The Connor-Davidson Resilience Scale-10 has been extensively used to assess resilience. In the current study, we examined the reliability, validity and dimensionality of this instrument using Rasch analysis, Mokken analysis and classical test theory. Using both item response theory and classical test theory provides a more comprehensive overview of the psychometric properties of the Connor-Davidson Resilience Scale-10.
