The purpose of this study was to evaluate the factor structure, invariance, reliability, convergent and discriminant validity of the Flourishing Scale using exploratory and confirmatory factor analysis in 2272 Greek adults (aged M = 35.54 years). We used the 3-faced validation method. After splitting the sample in three parts (20%, 40% and 40%), we established a structure in the first 20% part with Exploratory Factor Analysis. Later on, the structure was re-examined in the second 40% part with Confirmatory Factor Analysis, confirming the unidimensional structure of FS. This unidimensional structure was further cross-validated in the third part of the sample having equal power to the second one (40%) with a second CFA. In the final phase of the 3-faced validation method, strict measurement invariance was evaluated.
