Introduction: Various measuring tools have been used to estimate the outcomes of different forms of treatment for end-stage renal disease (eSRd).Survival, cost-effectiveness and quality of life (QOL) are the main parameters used to evaluate the treatment of eSRd. Aim: To assess the psychometric properties (reliability and validity) of the Greek version of the Missoula-VITAS Quality of Life Index (MVQOLI-15) in patients undergoing haemodialysis (Hd). Method: A sample of 79 patients undergoing Hd voluntarily participated in this pilot study. domain analysis of MVQOLI-15-Greek was conducted based on the data collected at the initial assessment. The reliability properties of the instrument were tested using the measures; internal consistency, repeatability, test-retest reliability and convergent validity (SPSS 13.0). Results: domain analysis demonstrated that all domains of the questionnaire had good variability. The MVQOLI-15-Greek internal consistency was satisfactory, with an overall Cronbach’s α at 0.74. Pearson’s r and intraclass correlation coefficient revealed strong correlations (ranging from 0.91 to 0.98) between initial assessment and re-assessment. The MVQOLI-15-Greek convergent validity analysis indicated that the domains were strongly related to the same construct. Conclusions: The findings of the study indicate that the Greek version of MVQOLI-15 provides satisfactory psychometric properties, supporting its use with clinical populations and in the context of national QOL measurement.
