title: Psychometric Properties of the Modified Personal Diabetes Questionnaire Among Chinese Patients With Type 2 Diabetes.
abstract: This study examined the psychometric properties of the Chinese version of the Personal Diabetes Questionnaire (C-PDQ). The PDQ was translated into Chinese using a forward and backward translation approach. After being reviewed by an expert panel, the C-PDQ was administered to a convenience sample of 346 adults with Type 2 diabetes. The Chinese version of the Summary of Diabetes Self-Care Activities (C-SDSCA) was also administered. The results of the exploratory factor analysis revealed a one-factor structure for the Diet Knowledge, Decision-Making, and Eating Problems subscales and a two-factor structure for the barriers-related subscales. The criterion and convergent validity were supported by significant correlations of the subscales of the C-PDQ with the glycated hemoglobin values and the parallel subscales in the C-SDSCA, respectively. The C-PDQ subscales also showed acceptable internal consistency (α = .61-.89) and excellent test-retest reliability (intraclass correlation coefficients: .73-.96). The results provide preliminary support for the reliability and validity of the C-PDQ. This comprehensive, patient-centered instrument could be useful to identify the needs, concerns, and priorities of Chinese patients with type 2 diabetes.
