OBJECTIVE: Flourishing, a holistic concept encompassing multiple domains of well-being, has gained significant interest in recent years. However, validated tools for measuring flourishing, mainly using VanderWeele's framework, remain unavailable for Brazilian Portuguese-speaking populations. This article describes the translation into Brazilian Portuguese, cross-cultural adaptation, and validation of the resulting versions of the Flourishing Index (FI) and Secure Flourishing Index (SFI).
METHODS: The instruments were translated and adapted following international guidelines for cross-cultural adaptation of self-report measures. In Study 1, psychometric properties were examined using exploratory factor analysis (EFA) in a general-population sample (n=359). Construct validity was assessed by correlating FI/SFI scores with quality of life, depression, anxiety, and posttraumatic growth. In Study 2, confirmatory factor analysis (CFA) was conducted in a sample of individuals with moderate depressive symptoms (n=252) to confirm the factor structure. Reliability and validity were evaluated in both samples.
RESULTS: EFA identified a five-factor structure for the FI and a six-factor structure for the SFI, consistent with prior studies. Cronbach's alpha ranged from 0.60 to 0.86, supporting internal consistency. CFA confirmed the multidimensional structures with appropriate fit indices (root-mean-square error of approximation [RMSEA] < 0.08, standardized root-mean-square residual [SRMR] < 0.08). Construct validity analyses demonstrated significant correlations between FI/SFI and mental health, quality of life, and posttraumatic growth.
CONCLUSION: The Brazilian Portuguese versions of the FI and SFI demonstrated appropriate psychometric properties, enabling comprehensive assessments of flourishing in diverse contexts. These validated tools can now be used to support flourishing research and intervention evaluation in Brazil.
