Objective: to construct and validate the Educational Content Validation Instrument in Health.
Method: methodological study that includes the establishment of the conceptual structure; definition of objectives and population; construction of items and response scale; selection and arrangement of items; instrument structuring; opinion of experts; pre-test and content validation.
Results: an instrument with 15 items was constructed and, after expert evaluation, eighteen items were obtained, divided into three domains: objectives (four), structure/presentation (nine), and relevance (two). Six items were modified since they presented a percentage of agreement below 0.8. Items of the total instrument presented good internal consistency (0.877) regarding domains.
Conclusion: an Educational Content Validation Instrument in Health was elaborated and validated, presenting good reliability, and may contribute to the practice of researchers and health professionals in the development of educational content.
