ABSTRACT Objectives: to build and validate an almanac to prevent the use of alcohol and other drugs among adolescents. Methods: a methodological study, based on the adaptation of Echer’s stages and on Culture Circles. The Content Validity Index and the Concordance Index were used for validity. Results: problematization in Culture Circles and literature review supported the elaboration of an almanac. In validity with eleven health judges, the material obtained a global Content Validity Index of 0.73 in the first version and 0.84 in the second version, with validation with five judges. In terms of concordance, the 95% value was obtained with four technical judges and 86.2% with nine participants from the target audience. Conclusions: the constructed and validated almanac has playful, dialogic and problematizing potential.
