The aim was evaluate the effect of two forms of brief intervention on the consumption pattern of teenage students living in urban and rural zones of Aguascalientes, Mexico. The participants were 58 teenagers in a clinical, randomized essay in three study groups: brief intervention -PIBA- (n=20), brief counseling (n=20) and a control group on the waiting list (n=18); each group had two levels: urban teenagers and rural teenagers Follow-up was carried out three and six months after they completed the treatment. The brief intervention involved 5 sessions while the brief counseling involved a single session. The study was carried out between 2005 and 2008. Non parametric analysis of repeated measures showed that PIBA and brief counseling significantly reduced consumption patterns in teenagers in the follow-up at three and six months after finishing treatment, unlike the control group that maintained its alcohol consumption levels. The analysis also shows that between teenagers from rural and urban zones, there are no significant differences in the reduction of the consumption pattern. Therefore, PIBA and Brief Counseling are effective interventions in reducing the consumption pattern of teenagers living in urban and rural zones. In a staggered treatment model, both interventions could be combined in a treatment package in which counseling should be the minimal initial intervention.
