Impact evaluation of the Program "Me and the others": A longitudinal study with a Portuguese youth sample

Addictions are an increasingly problem  among young people, with negative impacts in the short and in the long run. Prevention is therefore essential. The study that will be presented will provide the first results of a longitudinal impact evaluation (3-year impact quasi-experimental evaluation design with an intervention group and a comparison group) of the Portuguese Prevention Program ''Me and Other".  Sociodemographic variables of youth participants and variables of facilitarors (e.g., confort in the implementation) will be tested as moderators. Monitoring information (e.g., dosage) will also be analyse as a moderating variable. Preliminary results will give some light to the next steps.
