Abstract
PurposeDuring 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.Participants and MethodsSchool teachers from South Africa (N = 355) constituted the sample for the study and they completed the following scales: Connor-Davidson Resilience Scale-10, the Center for Epidemiological Studies Depression Scale, State-Trait Anxiety Inventory-Trait Scale, the Beck Hopelessness Scale, and the Sense of Coherence Scale.ResultsBoth item response theory and classical test theory provided strong evidence for the reliability and validity of the Connor-Davidson Resilience Scale-10. In addition, the analyses provided support for considering the scale as essentially unidimensional.ConclusionThe obtained results provide additional support for the reliability and validity, of the Connor-Davidson Resilience Scale-10 for samples from diverse contexts.
