The purpose of this study was to evaluate the factor structure and measurement invariance across gender and age of the Brief Resilience Scale (BRS) in 2272 Greek adults of the general population. The sample was split into three parts (20%, 40%, 40%). EFA was carried out in the first subsample (20%) evaluating 3 models. CFA was next carried out in the second subsample (40%) evaluating seven models. All models were examined further in a different CFA with a subsample of equal power (40%). The single factor of BRS was deemed unstable across the two CFA subsamples. A two-factor model was the optimal model emerged in the Greek context. Measurement invariance across gender and age was successfully established. Internal consistency reliability (α and ω) and AVE based convergent validity were adequate for the entire BRS. A consistent pattern of relationships emerged from correlation analysis with 12 different measures, suggesting convergent and discriminant validity. The distinctiveness of BRS from depression and stress was evidenced using CFA and EFA with different compound models of BRS and scales of depression, anxiety, and stress. These findings further confirmed that the Greek version of BRS has construct validity.
