Objective: To develop and validate an educational technology venous ulcers care. Method: Methodological study conducted in five steps: Situational diagnosis; literature review; development of texts, illustrations and layout; apparent and content validity by the Content Validity Index, assessment of Flesch Readability Index; and pilot testing. Results: The developed technology was a type of booklet entitled Booklet for Venous Ulcers Care, consisting of seven topics: Diet and food intake, walking and light exercise, resting with elevated leg, bandage care, compression therapy, family support, and keeping healthy habits. The apparent validity revealed minimal agreement of 85.7% in the clarity and comprehensibility. The total content validity index was 0.97, the Flesch Readability Index was 75%, corresponding to the reading “fairly easy”. The pilot test showed that 100% of people with venous ulcers evaluated the text and the illustrations as understandable, as appropriate. Conclusion: The educational technology proved to be valid for the appearance and content with potential for use in clinical practice.
