Cross-Cultural Validation of the Korean Version of the Chalder Fatigue Scale

Abstract

Current results suggest that K-CFQ is a valid and reliable measure of fatigue, and a better model fit of the three-factor structure of the K-CFQ implies potential cross-cultural differences in the dimensionality of fatigue.

Psychometric properties of the Korean version of the Occupational Fatigue Exhaustion Recovery Scale in a nurse population

“…Each item is scored using a 4‐point Likert scale ranging from “ less than usual = 0” to “ much more than usual = 3.” The total score ranges from 0 to 33, with higher scores indicting more severe fatigue. The convergent validity of the Korean CFQ was supported by a correlation with the PSQI ( r = 0.52; p < .01; Ha et al, ). Cronbach's alpha was 0.88 for the original scale (Cella & Chalder, ) and 0.88 for the Korean version (Ha et al, ).…”

“…Moreover, the PSQI has been used to examine convergent validity with the OFER scale in previous studies (Fang et al, ; Winwood et al, ). Permission was obtained to use all scales from the original developers and authors (Y. W. Cho et al, ; Ha, Jeong, Hahm, & Shim, ; Sohn, Kim, Lee, & Cho, ) who translated them into Korean.…”

“…The CFQ was developed in 1993 to measure fatigue (Cella & Chalder, ; Chalder et al, ). In this study, we used the version that was tested for validity in a Korean population (Ha et al, ). The Korean version of the CFS consists of 11 items divided into three subscales (i.e., physical fatigue, low energy, and mental fatigue; Ha et al, ).…”
