Abstract

The purpose of this study was to translate and validate the Comprehensive Inventory of Thriving(CIT) and its short version, the Brief Inventory of Thriving(BIT), in the Korean context. To achieve this, CIT and BIT items were translated into Korean through a cross-cultural validation process. Data were collected from 645 Korean adults via an online survey. Results of reliability and confirmatory factor analysis indicated that both K-CIT and K-BIT demonstrated good internal consistency. The 18-factor structure of the K-CIT and the single-factor structure of the K-BIT showed the best fit for the data. Analysis of convergent and discriminant validity revealed that K-CIT and K-BIT showed moderate correlations with positive and negative emotions and strong correlations with life satisfaction and meaning in life. An analysis of mean differences in the K-BIT based on demographic characteristics revealed no significant differences in gender or age, while significantly higher scores were observed for those who were married, who had a relatively higher income, and who had a religious affiliation. These findings suggest that both K-CIT and K-BIT are reliable and valid tools for assessing psychological thriving in Korean adults. Further research directions and practical implications of K-CIT and K-BIT are discussed.
