Noncommunicable chronic diseases are long-term conditions characterized by complexity and multifactorial etiologies. The objective of this study was to validate the book Updates on Noncommunicable Chronic Diseases: Applicability of Nutrition, Physical Exercise, Phytotherapy, and Medicinal Plants. The study was approved by the local ethics committee and followed a methodological design focused on the validation of instructional material. Content validation was conducted by 30 physicians representing different medical specialties. Eligibility criteria for expert judges included at least two years of professional practice following medical graduation and a specialist medical degree. Non-eligibility criteria included being a non-medical health professional or failure to sign the Informed Consent Form. Additionally, judges who did not complete the evaluation instruments within 15 days were excluded. Judges received, via WhatsApp, a digital version of the book (PDF) and a link providing access to the Invitation Letter, the Informed Consent Form, and the evaluation questionnaires. Data from the validation instrument were analyzed using Cronbach’s alpha coefficient and the Content Validity Index (CVI). All 30 judges completed the evaluations; of these, 53.3% were male, and 50% were between 51 and 60 years of age. The internal consistency of the instrument was high (Cronbach’s alpha = 0.8554), and all evaluated items achieved a global CVI of 1.00, with judges rating every item as fully adequate or adequate. The book was validated as an effective and comprehensive educational resource capable of supporting health professionals, students, and other stakeholders involved in the prevention and management of noncommunicable chronic diseases.
