Brief Resilience Scale (BRS) Portuguese Version: validity and metrics for the older adult population.

Objective: This study aims to analyze the psychometric properties of the new Brazilian-Portuguese version of the Brief Resilience Scale (B-BRS) in older adults.

Method: A sample of 1251 participants (54.20% women;  = 68.02 years,  = 6.52) completed the B-BRS and seven scales on successful aging and mental health. Confirmatory factor analysis was used to study the B-BRS dimensionality. Convergent and divergent validity was analyzed by means of examining the relationships of B-BRS with scales on successful aging and mental health.

Results: The results supported the unidimensionality of the B-BRS after controlling for wording method, as well as satisfactory reliability (ω = .79). B-BRS structure remained invariant across education level and income groups. B-BRS scores positively correlated with successful aging factors and negatively with psychopathology symptoms.

Conclusion: To conclude, our findings provide some evidence on the reliability and validity of the B-BRS, as well as its validation for use in the senior population.
