Psychometric properties of the revised Norwegian dispositional resilience (hardiness) scale.

In the 30 years that have elapsed since it was first introduced, the concept of hardiness has continued to attract the attention and interest of researchers from all over the world. The purpose of this study was to examine the reliability and factor structure of a revised Norwegian hardiness scale (Dispositional Resilience Scale 15; DRS-15). Using exploratory and confirmatory factor analytic strategies with a large sample of working adults (N = 7,280), support was found for a hierarchical structure comprising a general hardiness dimension and three sub-dimensions (commitment, control, and challenge). Overall, the results support the reliability and validity of the revised DRS-15 and underscore the importance of examining the psychometric properties and cultural appropriateness of translated scales.
