The main purpose of the study was to explain tobacco dependence and consumption of cigarettes from a motivational perspective on a sample of high school students of both sexes. We used four scales of the Wisconsin Inventory of Smoking Dependence Motives, a scale of parental rules and a scale of smoking friends; as well as two international measures for cigarette consumption and a tobacco dependence questionnaire. The multiple regression analysis of tobacco dependence showed that the key exposure, parental rules and positive reinforcement, accounted for 54.30% of the variance. In this study, was developed a structural model of the tobacco dependence that included the four motives and the number of days of consumption, which fits well with the data; all direct effects on measures of dependency were significant, as the covariance among the motives. According to the Wald statistic obtained in the latent class analysis, there were significant differences among the three groups in the four indicators: dependency, exposure to key, smoking friends and number of days of consumption.
