Brief Resilience Scale: testing its factorial structure and invariance in Brazil

Across two studies we aimed to provide evidences of validity and reliability for the Brief Resilience Scale (BRS) in Brazil. In study 1, 171 individuals participated (Age M = 21.9, SD = 6.59) and 232 in Study 2 (Age M = 26.3, SD = 7.06). Confirmatory factor analysis (CFA) supported the predicted one-factor solution, with five items and satisfactory internal consistence (α= 0.76). A multi-group CFA revealed partial measurement equivalence between our and the original (USA) versions of the BRS. The BRS correlated significant with positivity and personality traits. The composite reliability was satisfying; the convergent validity, measured with the average variance extracted, was slightly below the recommendations. Overall, the results show that the measure is psychometrically suitable for research in Brazil.
