Abstract

Although the Kidney Disease Quality of Life instrument (KDQOL-SFTM), which was designed to measure the comprehensive quality of life in patients with end stage renal disease, has been tested and widely administered in many other counties, it has not yet been translated, validated and reported for Korea. The primary purpose of this study was to validate a Korean version of KDQOL-SFTM and to evaluate its psychometric properties. The study subjects were 164 patients with hemodialysis or continuous ambulatory peritoneal dialysis in university dialysis centers in Korea. In order to investigate the reliability, test-retest reliability and internal consistency reliability were assessed. Both test-retest reliability and internal consistency reliability were found to be high. In order to investigate the construct validation, all the items of the SF-36 scales, an established generic QOL measures, were compared with an overall health rating scale in kidney disease-targeted scale. They found to be highly correlated with each other. Moreover, overall health rating scale was significantly correlated with symptoms/problems, effects of kidney disease, burden of kidney disease, cognitive function (p < 0.001), and quality of social interaction (p < 0.05). These results suggest that the Korean version of KDQOL-SFTM satisfies its reliability and validity in Korean patients with hemodialysis or continuous ambulatory peritoneal dialysis. This questionnaire provides important and clinically valuable information for understanding the health related quality of life in the Korean patients with dialysis.
