Reliability and validity of the Korean version of the 15-item Dispositional Resilience Scale

This study assessed the reliability and validity of the Korean version of the 15-item Dispositional Resilience Scale (DRS-15) in a sample of Korean adults. In a baseline study conducted in June 2015, the DRS-15, Center for Epidemiologic Studies-Depression Scale (CES-D), and Korean Resilience Questionnaire-53 (KRQ-53) were administered to 409 Korean adults aged 20-79 years. A 1-year follow-up study was conducted in June 2016, and the CES-D was administered to assess predictive validity. Confirmatory factor analysis identified three dimensions for the DRS-15: commitment, control, and challenge (χ²/df = 2.32, GFI = .90, AGFI = .88, RMR = .04, TLI = .91, NFI = .89, and RMSEA = .05), and concurrent and predictive validity were demonstrated via the CES-D and KRQ-53. Furthermore, the DRS-15 established known-group validity. Cronbach's alpha coefficients for internal consistency reliability of the three subscales ranged from .75 to .83. Three-week test-retest reliability coefficients ranged from .80 to .81. The KDRS-15 showed satisfactory construct and criterion validity and internal consistency.
