Development and Evaluation of Effectiveness of an Internet-based Brief Intervention for Alcohol Use Among Brazilian College Students

Study Overview
=================
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). The investigators will use the dismantling design to study the most effective components. Participants will be followed-up at 1, 3 and 6 months.
