Adolescent-oriented programs indicate that the most effective interventions to prevent tobacco and alcohol consumption include social ability training. This article reports on an educational intervention aimed at strengthening protective factors, self-esteem and assertiveness, applying primary prevention channels, based on the Multi-Component Motivational Stages theoretical model and Social Learning Theory. Measurements were made before and after the intervention. Results: we verified increased self-esteem scores with Me=63.1 at first measurement and Me=84.38 at the end of the intervention. A significant increase in assertiveness occurred after the intervention, with Me rising from 60 to 81.2 (p<.001). Average scores for self-esteem and assertiveness were significantly higher in the experimental group when compared to the control group (p<.001).
