摘要：Introduction: Alcohol consumption is a problem closely related to adolescence. At first, it tends to be established as a habit and after that as an addiction, when the individual in question still is an adolescent. Objective: The study sought to determine the effect caused by nursing intervention through “interconnected” peers on self-efficacy and alcohol consumption. Results: Statistically significant difference was shown post-intervention (z = -4.86; p = .000) and at follow-ups at three months (z = -4.78; p = .000) and six months (z = -4.78; p = .000); this is also activate in alcohol consumption at the post-intervention measurement (z = -4.74; p = .000) and at follow-ups at three months (z = -4.74; p = .000) and six months (z = -4.74; p = .000). Conclusions: Based on the objective of the study, it is possible to conclude that it is feasible to decrease alcohol consumption and favor self-efficacy in adolescents through “interconnected”.
