Abstract This methodological study aimed to describe the elaboration and validation of a digital booklet focused on sustainable practices toward adolescent health-promoting actions. It was conducted according to the following stages: preparation of the educational booklet; appearance and content validation with 21 judges and validation with a target audience of 53 adolescents. The drafting, elaboration, and assembly of the material’s layout were performed through data retrieved from the integrative review and interviews. The digital booklet was entitled “Uncomplicating Environmental Health”, with 29 pages in the A5 half-page format (14.8 cm width and 21.0 cm height), configured in landscape layout mode, made available for free, and accessible via mobile and fixed devices. The booklet was validated regarding appearance and content, with an overall Content Validity Index of 0.95, and judges’ validation through the Suitability Assessment of Materials tool was considered “superior”. The booklet achieved the target audience’s positive agreement for validation. It was considered valid to be used in health education for adolescents.
