There is a growing consensus regarding the multidimensional nature of successful aging (SA), including both the biomedical and psychosocial domains of the aging process. The Successful Aging Scale (SAS) is a self‐rated instrument addressing both of these components. The aim of this study was to analyze the psychometric properties of the Brazilian Portuguese version of the SAS (SAS‐B) with regard to reliability and validity in 949 Brazilian community‐dwelling older adults (53.60% women; M = 69.49 years; standard deviation = 7.67). Confirmatory factorial analysis (CFA) was performed to provide evidence on its structural validity. Convergent and divergent validity was studied by means of examining the relationships of SAS‐B with scales concerning resilience, life satisfaction, self‐esteem, social support, perceived stress, and health, as well as mental health. The CFA showed that the SAS‐B is multidimensional with three correlated factors ( χ 2 / df = 2.74; standardized root mean square residual = 0.03; root mean square error approximation = 0.04; comparative fit index = 0.91), and its factors showed adequate reliability ( ω = 0.70 for Healthy living habits, ω = 0.69 for Adaptive coping, and ω = 0.70 for Engagement with Life). Convergent and divergent validity was endorsed by correlations with related factors. The SAS‐B is a reliable and valid self‐rated instrument to measure the SA from a multidimensional perspective.
