Abstract
Purpose: To develop and evaluate the reliability and validity of a Diabetes-Related Distress Questionnaire for Chinese-speaking patients with diabetes. Methods: The Diabetes-Related Distress Questionnaire (DRDQ) included 11 quality-of-life questions translated from a Diabetes, Attitudes, Wishes, and Needs study and four native items developed by researchers based on patients’ experiences. A sample of 981 Chinese-speaking patients with diabetes in Taiwan was invited to complete the questionnaire. Results: A minimum of 4.2?% of patients used each response option for each item. Exploratory factor analysis suggested a two-factor structure, representing treatment-related distress (factor 1) and progression-related distress (factor 2). The mean loading of items on their corresponding factor was high (0.60), while the mean loading on the other factor was low (0.10). A confirmatory factor analysis confirmed a single structure of the DRDQ (root-mean-square error of approximation?=?0.063, comparative fit index?=?0.93). The Cronbach’s alpha was 0.89 for the DRDQ scale, 0.87 for the factor 1, and 0.68 for the factor 2. As expected, people with insulin-treated and HbA1c?>?7?% reported significantly greater negative scores than their counterparts on the total score and all items of the DRDQ, with the exception of item 2. A moderate effect size was demonstrated between insulin known groups (ranging from 0.14 to 0.46) and between HbA1c known groups (ranging from 0.08 to 0.87). Conclusions: The DRDQ is a psychometrically sound instrument that can be used to assess diabetes-related distress in Chinese-speaking patients in Taiwan. ? 2015, Springer International Publishing Switzerland.
