RESUMEN
OBJECTIVE: To validate an educational material on diabetes through an expert consensus for its implementation into a web site. MATERIAL AND METHODS: An observational study was carried out in a group of health professionals, for which an educational material was developed for patients with diabetes. Topics included nutrition, physical exercise, control indicators, complications, pharmacological treatment, among others. The language, text and figures were focused on easy comprehension, additionally, a section of didactic activities to be answered by the patient with diabetes at the end of each module was included. To evaluate the educational material by health professionals, an instrument was designed and validated. Once all the educational material was available, each of the modules was sent by e-mail to at least three clinical experts in the assigned topic, as well as the instrument for the evaluation of the module. RESULTS: Thirty-seven experts were included in the study, 76% rated the educational modules evaluated as highly adequate, while only 24% rated them as adequate. The instrument used obtained a good level of internal consistency, with a Cronbach's alpha coefficient of 0.92. In the dimensions of the instrument, the lowest Cronbach's alpha score was that of "call-to-action", with a value of 0.71. CONCLUSION: The diabetes educational material was rated as highly appropriate by the clinical experts. The developed instrument has an adequate content validity, as well as a good level of internal consistency.
