Measuring health: related quality of life in hemodialysis patients. Psychometric properties of the Missoula-VITAS Quality of Life Index (MVQOLI-15) in Greece

Abstract

Different measuring tools have been used to understand the outcomes of end-stage renal disease (ESRD) therapies. However, survival, cost-effectiveness and quality of life (QOL) are the main parameters to evaluate treatment of ESRD. The current study meant to assess the psychometric properties (reliability and validity) of the Missoula-VITAS Quality of Life Index (MVQOLI-15) translation to Greek in patients undergoing hemodialysis (HD). A total sample of 79 HD patients voluntarily participated in this pilot study. Domain analysis of MVQOLI-15-Greek was conducted based on the collected data at initial assessment. The reliability properties of the instrument were tested using the following measures; internal consistency, repeatability, test-retest reliability and convergent validity. Domain analysis demonstrated that all domains of the questionnaire had good variability. MVQOLI-15-Greek internal consistency was satisfactory with an overall Cronbach’s a 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. MVQOLI-15-Greek convergent validity analysis indicated that the domains were strongly related to the same construct. The findings of the study indicate that the Greek version of MVQOLI-15 provided satisfactory psychometric properties supporting its use within pathological populations and in the context of national QOL measurement.

Management of Pain and Quality of Life in Patients with Chronic Kidney Disease Undergoing Hemodialysis

“…Through the study of the psychometric properties of the PSEQ (Theofilou, 2014) and the study of the psychometric properties of the MVQOLI (Theofilou et al, 2013), their validity was found to be highly satisfactory. Also, the fact that almost all patients responded with eagerness and ease to the questionnaires shows that they are easy tools and appropriate for use in studies.…”

“…The internal validity of the Greek version of the questionnaire was satisfactory with Cronbach's alpha of 0.74. (Theofilou et al, 2013).…”

“…Consequently, an increased interest in the QoL of hemodialysis (HD) patients is observed (Theofilou & Panagiotaki, 2010;Theofilou 2012;Theofilou 2013a;Theofilou 2013b;Theofilou, Aroni, Ralli, Gouzou, & Zyga, 2013).…”

The impact of Kt/V urea-based dialysis adequacy on quality of life and adherence in haemodialysis patients: a cross-sectional study in Greece

“…The scale has been translated and validated into Greek. 14 , 15 MSPSS, which consists of 12 items, was developed by Zimet et al 16 to identify the social support factors perceived by the individuals. The scale is comprised of 3 groups depending on the source of support, each group consisting of 4 items.…”

Measuring pain self-efficacy and health related quality of life among hemodialysis patients in Greece: a cross-sectional study

“…The scale has been translated and validated into Greek. 14,15 The Pain Self-Efficacy Questionnaire (PSEQ) is a 10-item questionnaire developed to assess the confidence people with ongoing pain have in performing activities while in pain. It consists of two domains, physical and psychological.…”
