This study examined alcohol use and related social normative perceptions among a sample of 1,886 Central-Eastern European high school students. The youth represented in the study averaged 16.5 years of age and were from several localities in the countries of Hungary, Slovakia, Czech Republic, and Romania. Data for the study were collected through a school-based alcohol use survey that was completed in June 2005. Our results support the hypothesis that drinking was related to perception of the prevalence of alcohol use by schoolmates and by the number of friends who drink and/or engage in episodic heavy drinking. Specific implications of findings in terms of substance use prevention are discussed. In addition, the need for future research and the limitations of the current research are discussed. This study was largely financially supported through an international grant from the College of Health and Human Performance, Brigham Young University.
