Abstract

The EPOCH Model was developed by Kern et al. (2016) to measure adolescents’ flourish referring to sustainable well-being as a product of their individual strengths and resources. Kern et al. (2016) validated the original EPOCH scale using American and Australian adolescents aged 8-18 years old. This study aimed to validate a Korean translation of the EPOCH scale, a Korean adolescents’ flourish scale, using a sample of Korean adolescents. The participants in the study were 507 middle school and high school students aged 12-18 years old. The data were analyzed using factor analyses, ANOVAs, reliability analyses, and correlational analyses in Jamovi and AMOS. The results indicated that a second-order factor model with 5 factors at the first level and 2 factors at the second level was appropriate for middle school students, while a second-order factor model with 5 factors at the first level and 1 factor at the second level was appropriate for high school students. The reliability of the Korean adolescents’ flourish scale was .90-.95. Male students reported higher flourish levels than female students. Middle school students’ flourish level was higher than that of high school students. Moreover, Korean adolescents’ flourish was positively related to psychological well-being, life satisfaction, and school adjustment and negatively associated with mental health problems.
