Abstract

Main objective of this study is to validate the Health-Related Quality of Life (HRQOL-20) in the Malaysian population. Reliability and internal consistency were evaluated using the test-retest method and Cronbach's alpha. Responsiveness was expressed as the effect size. Internal consistency was excellent (Cronbach's alpha value = 0.68 to 0.87). Test-retest correlation coefficients and intraclass correlation coefficient were significant (ICC = 0.58 and 0.91) as well as the high degree of sensitivity and specificity. The HRQOL-20 is a reliable, valid and sensitive to clinical changes in the Malaysian urological population.
