Development and Validation of a Culturally Adapted Patient‐Reported Experience Measure for Diabetes Care in Thailand: Mixed‐Methods Study

The development of this instrument actively involved patients throughout key stages. During content validation, individuals living with diabetes participated in an expert panel and provided feedback on item clarity, relevance and comprehensiveness. Their suggestions directly influenced revisions to the questionnaire. For face validity, a pilot test was conducted with patients in a primary care setting, gathering their insights on wording, usability and cultural appropriateness. Their contributions ensured the tool was clear, acceptable and contextually relevant to Thai people living with diabetes.
