Adaptation and validation of the Kidney Disease Quality of Life-Short Form questionnaire in the Greek language.

Aim: The aim of this study was to examine the validity, reproducibility and internal consistency of a Greek translation of the Kidney Disease Quality of Life-Short Form (KDQOL-SF) questionnaire.

Methods: The KDQOL-SF questionnaire was translated from English to Greek and was administered in 240 randomly selected patients undergoing hemodialysis in six Renal Units in Greece. The instrument's validity was tested by examining the association between patient's KDQOL-SF scores and comorbidity assessed with the Index of Coexistent Disease.
