Brief Summary

This project aims to develop and evaluate the effectiveness of an Personalized Normative Feedback (PNF) intervention via the internet, through a randomized clinical trial for alcohol consumption among Brazilian college students, as well as evaluating the most effective components of the PNF (normative and list of consequences). The sample is composed of college students aged between 18 and 30 years. Participants allocated into four different groups: control, full intervention (PNF), feedback with normative components (FN) and feedback with list of consequences (FLC).
