TLDR
The Korean EQ-5D exhibits good validity and sensitivity in various rheumatic conditions, and although its reliability and responsiveness were not excellent, it seems acceptable if condition-specific measures are applied together.Abstract:
Objectives: This study aimed to determine the cross-cultural adaptation and validation of the Korean version of the EQ-5D in rheumatic conditions. Methods: Translation, back-translation and cognitive debriefing were performed according to the EuroQol group’s guidelines. For validity, 508 patients were recruited and administered the EQ-5D, Short-Form 36 and condition-specific measures. Construct validity and sensitivity were evaluated by testing a-priori hypotheses. For reliability, another 57 patients repeated the EQ-5D at 1-week interval, and intra-class correlations (ICC) and kappa statistics were estimated. For responsiveness, another 60 patients repeated it at 12-week interval within the context of clinical trial, and standardized response mean(SRM) were calculated. Results: The cross-cultural adaptation produced no major modifications in the scale. The associations of the EQ-5D with the generic- and condition-specific measures were observed as expected in hypotheses the higher: EQ-5Dindex and EQ-5DVAS scores, the better health status by generic- or condition-specific measures, and the better functional class. The ICCs were 0.751 and 0.767, respectively, and kappa ranged from 0.455 to 0.772. The SRM were 0.649 and 0.410, respectively. Conclusion: The Korean EQ-5D exhibits good validity and sensitivity in various rheumatic conditions. Although its reliability and responsiveness were not excellent, it seems acceptable if condition-specific measures are applied together.read more

TL;DR: This study establishes the South Korean population-based preference weights for EQ-5D based on values elicited from a representative national sample using the time trade-off (TTO) method and the value set derived here is based on a representative population sample, limiting the interpolation space and possessing better model performance.

Comparing the psychometric properties of the EQ-5D-3L and EQ-5D-5L in cancer patients in Korea.
TL;DR: The EQ- 5D-5L had greater informativity and lower rate in the ceiling effect than those values of the EQ-5D-3L and showed good construct validity and reasonable reliability, and may be preferable to the EORTC QLQ-C30.

TL;DR: Prevalence of RLS estimated based on the IRLSSG diagnostic criteria is substantially lower in South Korea than in Western countries, suggesting strong association between RLS and DSM-IV depression and anxiety disorders.

TL;DR: Examination of relationships of sleep duration with sociodemographic and health‐related factors, psychiatric disorders and sleep disturbances in a nationwide sample in Korea found that short or long sleep is associated with psychiatric Disorders and/or sleep disturbance, therefore attention to the mental health of short orLong sleepers is needed.

TL;DR: The revised criteria for the classification of rheumatoid arthritis (RA) were formulated from a computerized analysis of 262 contemporary, consecutively studied patients with RA and 262 control subjects with rheumatic diseases other than RA (non-RA).
