ABSTRACT

Aims: To develop and evaluate a diabetic diet management questionnaire for patients with T2DM.
Methods: The item pool was formulated based on a literature review and in-depth interviews. An initial questionnaire containing three factors and 30 items was constructed through two rounds of Delphi expert consultation and a preliminary test. A total of 334 patients with T2DM in the Yangtze River Delta region were surveyed to test the reliability and validity of the questionnaire.
Results: Three factors with 15 items, including Knowledge management, Attitude management and Practice management of a diabetic diet, were extracted by exploratory factor analysis. The final items explained 51.475% of the total variance, and the content validity index was 0.856. The Cronbach's alpha coefficient was 0.815, and the test-retest reliability was 0.742.
Conclusion: The questionnaire was proven to be a reliable and valid tool that allows nurses to evaluate the diet management ability of patients with T2DM. The evaluation outcomes can serve as a basis for individualized health education and interventions for patients with T2DM.
