The use of alcohol and other drugs is considered a global problem, since it brings several consequences to public health. With adolescents, these problems can be even more serious, since the youth brain is still under development and is not prepared to deal with the effect of psychoactive substances. Considering parents as having an essential role in this stage of development of their children, this project aims to investigate the impact that parenting styles have in the progression of drug use of Brazilian students. Furthermore, the objective is to assess the moderating effect of parenting styles on the effectiveness of the governmental program #Tamojunto to prevent drug use among adolescents. The data analyzed are from the research entitled: "Evaluation of results of the school program to prevent the use of drugs #Tamojunto (Unplugged): A randomized controlled trial in six Brazilian cities." This project aims to analyze 6,637 students, aged 11-15 years in 72 public schools. The expected results are the production of 3 scientific articles. Article 1 will use Structural Equation Modeling to analyze the moderating effect of parenting styles on the effectiveness of the school program to prevent the use of drugs #Tamojunto. Article 2 will evaluate the moderation model of alcohol use onset in adolescence, considering the sex, parental styles, socioeconomic status, consumption of alcohol and other drugs by peers and parents. Article 3 aims to assess the impact of parenting styles on the adolescent drug use trajectory through the Latent Transition Analysis. Thus, it will be possible to improve the knowledge to allow the development of more effective prevention programs as well as the comprehension of moderators that may be involved in the effectiveness of these programs.
