“…A previous study reports that an improvement in HbA1c was associated with an excellent internal consistency and validity for Malaysian adult diabetic population. This is consistent with other previous studies which had validated the translated versions of DQOL questionnaire in Chinese, Turkish, Iranish and Spanish populations (17)(18)(20)(21)(22) The evaluation of the face validity of DQOL questionnaire had shown that most patients could understand this questionnaire easily. Attaining a satisfactory level of face validity is an important criterion of a valid questionnaire, because this will enable us to draw valid responses from the respondents.…”

“…From the findings of previous studies, a significant correlation exists between the total DQOL score and the number and severity of diabetic complications and the impact of different medical interventions for diabetes (17)(18). DQOL questionnaire has been translated and validated into various languages such as Spanish, Turkish, Japanese, Chinese, Taiwanese and Iranian (17)(18)(19)(20)(21)(22).…”

Objective: We aimed to validate the Malay version of Diabetes Quality of Life (DQOL) questionnaire for Malaysian adult population with type 2 diabetes mellitus (DM).Methods: This is a cross-sectional study to validate Malay version of DQOL among the adult diabetic patients. DQOL questionnaire has 46 items consist of three domains, namely Satisfaction Domain, Impact Domain and Worry Domain. Both forward and backward translations from the English version of DQOL into Malay version were performed. After the face validity of the Malay version was established, it was then pilot-tested. Finally, the validity and reliability of the final Malay version of DQOL questionnaire were evaluated.Results: There were 290 patients participated in this study with a mean (SD) age of 53.1 (10.0) years. The Cronbach's alpha coefficients of the overall items and the main domains were between 0.846 and 0.941. The Pearson's correlation coefficients for the three domains were between 0.228 and 0.451. HbA1C was found to be positively correlated with Impact Domain (P = 0.006). The Worry Domain was associated with diabetic retinopathy (P = 0.014) and nephropathy (P = 0.033).Conclusion: The Malay version of diabetes quality of life (DQOL) questionnaire was found to be a valid and reliable survey instrument to be used for Malaysian adult patients with diabetes mellitus.

“…The satisfaction subscale of the Chinese version of the Diabetes Quality of Life (DQoL) Scale (Huang et al, 2008) was used to assess how satisfied subjects were with their lives as it related to diabetes. The satisfaction subscale of the DQoL is a 15-item scale with a 5-point Likert scale ranging from 1 (very dissatisfied) to 5 (very satisfied).…”

Background Diabetes quality of life (DQoL) instrument has been widely used to measure quality of life among diabetes patients. This study aimed to develop a revised version of DQoL instrument that incorporated issues of redundancies in the items and strengthen the basis of validity of the instrument. Methods This was a cross-sectional study where diabetes patients were recruited from December 1, 2014, until end of March 2015 at a public health clinic in Peninsular Malaysia. A questionnaire that included patients' information and DQoL instrument was distributed to patients. Item selection of DQoL instrument was conducted to screen and finalize the items based on issues of missing values and redundancy. Validity testing was conducted for the revised DQoL instrument based on exploratory factor analysis, confirmatory factor analysis, and Rasch analysis. Results The pattern structure matrix yielded three domains similar to the original version with 18 items. The minimum factor loading from the structure matrix was 0.358. The item's and person's reliability was excellent with 0.92 and 0.84 for “satisfaction” domain, 0.98 and 0.60 for “impact” domain, and 0.99 and 0.57 for “worry” domain, respectively. Confirmatory factor analysis has dropped 5 items and the revised version of DQoL contained 13 items. Composite reliability of the revised version was computed for “satisfaction” domain (0.922; 95% CI: 0.909–0.936), “impact” domain (0.781; 95% CI: 0.745–0.818), and “worry” domain (0.794; 95% CI: 0.755–0.832). Conclusion A revised version of DQoL that maintains the conceptualization of “satisfaction,” “impact,” and “worry” with 13 items was successfully developed.

Evaluating the reliability, validity and minimally important difference of the Taiwanese version of the diabetes quality of life (DQOL) measurement

Abstract: Background: Few diabetes HRQOL instruments are available in Chinese language. We tested psychometric properties of a Diabetes Quality of Life (DQOL) in Chinese language for diabetes patients in Taiwan and estimated its minimally important differences (MIDs).
