title: The validation of the EQ-5D in Malaysian dialysis patients.
abstract: The EQ-5D is a quality of life instrument that measures five dimensions of health. This study investigated the reliability and validity of its use in the Malaysian dialysis population. Test-retest reliability, convergent and discriminant validity were assessed. Responses of 86 subjects who completed both surveys were used in analysis. Test-retest reliability using Cohen's kappa was acceptable in four out of five dimensions, with the exception of self-care. Convergent validity was present. Discriminant validity was found in only two out of six hypotheses tested. In conclusion, the EQ-5D has potential in this population but further study is required.
