Cross-Cultural Adaptation and Content Validity of the Diabetes Self-Management Questionnaire-Revised to Brazilian...

Background and Purpose: Self-management activities are essential for individuals with diabetes to effectively control their disease and prevent complications. This study aimed to culturally adapt the Diabetes Self-Management Questionnaire-Revised (DSMQ-R) into Brazilian Portuguese and to verify its content validity among patients with diabetes. Methods: A methodological study was conducted and comprised the following steps, as recommended by the literature: translation, synthesis of translations, back-translation, evaluation of the Brazilian Portuguese version by an expert committee, and pretest. The expert committee evaluated the semantic-idiomatic, conceptual, and cultural equivalences, and the content validity index (CVI) was calculated. The pretest of the instrument was conducted using cognitive interviews. Results: Nine of the 27 items of the DSMQ-R had a CVI below .80 and were thus revised and reformulated. The pretest of the Brazilian Portuguese version was conducted with 30 patients with type 1 diabetes and 30 with type 2. Participants suggested minor amendments for a better understanding of single items, resulting in the final Brazilian Portuguese version. Conclusion: The translation and cultural adaptation of the Brazilian version of the DSMQ-R were performed according to recommended standards and showed content validity evidence.
