The sampling was not probabilistic, because the intervention was applied in all students of the first years of selected junior high schools. Twelve sessions were carried-out, measurements of variables results before and after the intervention were realized. At the end of intervention the proportion of tabacco and alcohol consumption was lessen in experimental groups. The self-esteem and self-efficacy index showed differences of significant measurements between experimental and control group where the experimental group presented higher means and averages.
