The aim of this study was to develop the Korean version of the Warwick-Edinburgh Mental Well-being Scale (K-WEMWBS) and to examine its factorial structure, reliability, and convergent/discriminant validity.
The K-WEMWBS showed good content validity. Confirmatory factor analysis supported a single factor structure. The Cronbach's alpha value for the K-WEMWBS was 0.944, which demonstrated good internal consistency. Test-retest reliability at 2-8 weeks was high (0.789). The K-WEMWBS showed high correlations with mental health, positive affect, and quality of lifescales. Moderate negative correlation was observed between the K-WEMWBS and the negative affect scale. Discriminant validity was partially identified. Statistically significant differences in scores were observed between the psychiatric patient group and the control group.
CONCLUSION:
The results of this study indicate that the K-WEMWBS is a reliable and valid instrument for assessment of mental well-being, particularly the positive aspects of mental health.
