“…The need to assess QOL in various diseases led to the development of disease-specific instruments [6,7,8,9]. Survey instruments for HRQOL in kidney disease have been successfully used in dialysis patients and have shown adequate validity (i.e., they measure what they were intended to measure), reliability (i.e., their results are consistent, or remain similar under stable conditions), responsiveness (i.e., a change in the observed score reflects a true change in patient’s condition), and sensitivity (the ability to reflect true changes or differences when such changes exist) [8,10].…”

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. Reproducibility was examined by readministering the questionnaire in 50 randomly selected patients within 1 month. Internal consistency was assessed by estimating Cronbach’s alpha coefficient. Results: Patients were divided into two groups according to the severity of comorbidity assessed with the Index of Coexistent Disease. Those with less comorbid conditions had significantly higher scores in most components of the KDQOL-SF questionnaire, confirming its validity. The correlation coefficients between the two administrations of the instrument ranged from 0.88 to 0.98 for each of the main components, which was above the desired level of 0.85. Cronbach’s alpha coefficient ranged from 0.91 to 0.92 for the various components, values well above the minimum desired 0.70 level. Conclusions: The present study shows that the Greek version of the KDQOL-SF questionnaire has high validity, reproducibility and internal consistency. Production of validated translations of the KDQOL-SF questionnaire in various languages will help promote health-related quality of life of end-stage renal disease patients all over the world.

“…The DIMS includes 44 items measuring four scales, with a higher score representing a better HRQOL. A previous validation study of the DIMS indicated high internal consistency for all scales, good test-retest reliability, and good patient-clinician agreement [8].…”

“…For ADDQoL, there were 12 interviews (19), for D-39 an unknown number of interviews with patients (7) and for DIMS and DCP no conversations with a patient were mentioned (14,21). We did not find any qualitative research with international design in the development of a DR-QoL instrument.…”

“…During the past few decades, considerable effort has been devoted to the study of patients' self-management behaviours and adherence to the treatment. In DR-QoL research, questionnaires that are in use are listed in Appendix 1 (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). ATT39, PAID, DDS, the QSD-R, DHP, ADS, and ADDQoL are focused only on some aspects such as diabetes-related distress or additionally on the activity or the eating behaviour.…”

The DOQ-30 is a new broadly conceptualised DR-QoL instrument addressing a variety of obstacles patients might confront in everyday life. It is based on qualitative research in six European countries and reveals good internal reliability, and external and construct validity. ABSTRACTBackground: Patients with type 2 diabetes reveal different obstacles in living with the disease. The EGPRN initiated a qualitative research EUROBSTACLE to create a broadly conceptualized diabetesrelated quality of life (DR-QoL) instrument. It led to the development of the diabetes obstacle questionnaire (DOQ), a five-point Likert-scaled measure, consisting of 78 items in eight scales. Objectives: To develop and validate a short, easy-to-use version of the DOQ. Methods: A cross-sectional study with the DOQ was carried out. Participants answered the DOQ and GPs added some clinical data from their medical records. Data of 853 patients from Belgium, France, Estonia, Serbia, Slovenia, and Turkey were included in the analysis. The selection of items for the short version of the DOQ was achieved with exploratory factor analysis (EFA). Construct validity was proved with EFA and Pearson correlations between the DOQ and the new DOQ-30. Internal reliability was established with Cronbach's alpha. Results: DOQ-30 resulted in 30 items in nine subscales. It explained 49.8% of items' variance. It shows a considerable good internal reliability and construct validity. Conclusion: The DOQ-30 is a five-point Likert-scaled broadly conceptualized measure of DR-QoL. It addresses a variety of obstacles, such as social, psychological, cognitive and behavioural. The DOQ-30 is ready for implementation in general practice and research in Europe as a valuable instrument to assess DR-QoL.
