What Makes Koreans Happy?: Exploration on the Structure of Happy Life among Korean Adults

The current study explored the perceptions of Korean people about what can make them happy and constructed a comprehensive measurement of happiness of Korean. A total of 61 Korean adults participated in Focused Group Interview (FGI), where they were asked three questions (e.g., What makes you happy? What could make you happier than now? In general, who is a happy person?). Participants’ responses were reviewed by the present investigators independently and 152 statements of happy life with 18 categories were derived from content-analysis. The list of 152 statements of happy life was administered to 517 Korean adults to assess the importance of each item for Koreans’ happy life through the objective rating scale (6-point Likert scale). Confirmatory factor analysis showed that most factors were unidimensional. The items with low reliability were deleted and some new items were added, resulting in the experimental form of the Happy Life Inventory with 156 items and 18 categories including a new category of religion. The preliminary form of the Happy Life Inventory and the Psychological Well-being scale were administered to a nationwide sample of 1503 Korean adults in order to assess their happiness through 6-point Likert scale. The responses from 877 participants were submitted to exploratory factor analysis. The items with low factor loadings were excluded and 98 items with 16 factors were included in the final version of the Happy Life Inventory. Confirmatory factor analysis of the responses from 611 subjects confirmed that the 16 factor model was appropriate and most categories had one underlying dimension with moderate to high reliabilities. Correlations between the Happy Life Inventory and the psychological well-being scale supported construct validity of the Happy Life Inventory. Suggestions for further research were discussed.
