“…The KDQOL-36 was found to be a reliable instrument. The internal consistency (Cronbach’s alpha > 0.8) observed in the present study was good and comparable to that observed in other populations such as Mainland China [ 36 ], Thailand [ 37 ] and the US [ 32 ]. The internal consistency of this instrument was much higher than that found in a similar study previously conducted in Hong Kong [ 8 ] which may be due to our larger sample size.…”

AimThe aim of this study was to evaluate the validity, reliability and sensitivity of the disease-specific items of the Kidney Disease Quality of Life-36 (KDQOL-36) in Chinese patients undergoing maintenance dialysis.MethodsThe content validity was assessed by content validity index (CVI) in ten subjects. 356 subjects were recruited for pilot psychometric testing. The internal construct validity was assessed by corrected item-subscale total correlation. Confirmatory factor analysis (CFA) was used to confirm the factor structure. The convergent validity was assessed by Pearson’s correlation test between the disease specific subscale scores and SF-12 version 2 Health Survey (SF-12 v2) scores. The reliability was assessed by the internal consistency (Cronbach’s Alpha coefficient) and 2-week test–retest reliability (intraclass correlation coefficient (ICC)). The sensitivity was determined by performing known group comparisons by independent t-test.ResultsThe CVI on clarity and relevance was ≥ 0.9 for all items. Corrected item- total correlation scores were ≥0.4 for all, except an item related to problems with access site. CFA confirmed the 3-factor structure of the disease-specific component of the KDQOL-36. The correlation coefficients between the disease-specific domain scores and the SF-12 v2 physical and mental component summary scores ranged from 0.328 to 0.492. The reliability was good (Cronbach’s alpha coefficients ranged from 0.810 to 0.931, ICC ranged from 0.792 to 0.924). Only the effect subscale was sensitive in detecting differences in HRQOL between haemodialysis and peritoneal dialysis patients, with effect size = 0.68.ConclusionThe disease-specific items of the KDQOL-36 are a valid, reliable and sensitive measure to assess the health-related quality of life of Chinese patients on maintenance dialysis.

“…A sample size of at least 200 is needed to determine adequately precise reliability coefficients [ 38 ]. The 2-week test-retest reliability of the adapted KDQOL was acceptable and comparable to those observed in previous studies [ 10 , 36 , 37 ].…”

“…We did not observe any gender differences in access or use of the internet/electronic devices which is in keeping with findings in literature. [52,53] Participants required a mean time of minutes to complete the electronic version of the KDQOL-36 which is lower than the mean time of 15 minutes participants required to complete the paper format in the study by Thaweethamcharoen et al [54] It was not surprising that the participants who recorded the longest completion times also had the least experience of using computers as reported by previous studies. [10,55,56] However, their completion times may reduce over time as Erharter et al [57] showed that with regular use, the time required by patients' to complete an ePROM may reduce by as much as 30%.…”

“…Thus, quality of life should be measured and monitored for better understanding of patients' condition [6]. This can also help to identify subgroups with relatively poor perceived health and guide interventions to improve their situations and avoid further serious consequences [4].…”

ResultsAmong the 81 HD patients studied (49 males + 32 females) aged 50.6 ± 12.7 years, HRQOL scores were poor in all domains and subscales. The mean total score was 47.2 ± 25.2, mean Physical Health Composite (PHC) = 35.57 ± 7.34 and mean Mental Health Composite AbstractThis cross-sectional descriptive study was carried out at the hemodialysis unit of Karmouz Health Insurance Hospital, Alexandria, Egypt. The study was conducted on adult End-stage renal disease (ESRD) patients maintained on regular hemodialysis treatment for ≥1 year. Aim was to assess self-perception of ESRD patients undergoing regular Hemodialysis (HD) of their health-related quality of life (HRQOL) and explore resulted scores using kidney disease quality of life short form 36 instrument (KDQOL SF-36). A total of 81 eligible patients joined the study (49 males and 32 females). Aged 50.6 ± 12.7 years. Results showed that HRQOL of HD patients was very poor in all domains. The mean total score was below 50 (out of 100 point) with mean Physical Health Composite (PHC) = 35.57 ± 7.34 and mean Mental Health Composite (MHC) = 36.76 ± 10.22. In general, scores were relatively higher in males, younger age groups, high educational level, employed and/or higher family income. Regarding clinical prolife, this study showed that scores were lower among patients suffering anemia, dyslipidemia, hypoalbuminemia and/or those with comorbidities. Scores for general health survey were significantly lower in anemic patients (with hemoglobin level <11g/dL). Working patients had significantly higher scores than non-working or retired. The study also showed that employment was the only significant predictor for total HRQOL score in a multiple linear regression model was designed to predict total score, while controlling for hemoglobin level, age, duration of being on HD (p = 0.028).
