Well-being is one of the most studied constructs in the field of Positive Psychology. A recent indicator of this construct is the thriving, which is related to a positive state of mental, physical and social functioning. The present study's objective was to collect validity evidence for the comprehensive and brief versions of the Inventory of Thriving in Brazilian samples. The study involved 801 participants, of both sexes, between the ages of 16 and 76 years, who responded to the Brazilian versions of the scales and other instruments. Confirmatory factor analysis showed that the comprehensive version was composed of 54 items equally distributed among 18 first-order factors; and the brief version was composed of a single factor consisting of 10 items. With respect to convergent validity, the comprehensive and brief versions' positive factors were positively correlated with life satisfaction, optimism, core self-evaluation, and flourishing, while the comprehensive version's negative factors were negatively correlated with these constructs. According to the results, it is recommended to use the scales in future research on thriving.
