Abstract. The aim was to determine the effectiveness of two motivational interventions for smoking cessation in teenagers. A multicentre randomized experimental study was conducted on 5 Secondary Schools. Individual interventions were proposed to smokers teenagers who wanted to quit. Family doctors developed the intervention in the Secondary Schools through a stratified random assignment to the intensive and brief intervention. 92 teenagers have participated with no differences at the beginning of interventions. In the sample, 82% were daily smokers with low dependency (62%) and high / moderate motivation for cessation (88%). A 47% received the intensive intervention; reaching smoke cessation of a 64% ± 5.0 in the first month (20% better in intensive intervention) a 42% ± 5.2 at the sixth month and a 27% ± 4.6 at 12 months (no difference). Brief intervention appears to be more efficient, while more research would be warranted to determine the profile of the teenager who would benefit from intensive intervention.
