Abstract

This study aimed to validate the Beck Depression Inventory (BDI) in the Malaysian urological population. Reliability and internal consistency were evaluated using the test-retest method and internal consistency was assessed using Cronbach's alpha. Responsiveness was expressed as the effect size. Internal consistency was high (Cronbach's alpha value = 0.56 to 0.87). Test-retest correlation coefficient and intraclass correlation coefficient were significant (ICC = 0.56 to 0.87) and a high degree of sensitivity and specificity. The BDI is thus a reliable and a valid instrument to be used in Malaysia.
