The current study sought to establish in vivo misperception of blood alcohol concentration (BAC) as a predictor of event-specific alcohol-consumption-related negative consequences. During spring 2010, 225 (56.4% male) college students, who had consumed at least one alcoholic drink within the 2 hr prior to assessment, completed a questionnaire, gave a breath sample to assess breath alcohol content, and later completed a follow-up questionnaire. Underestimation of BAC was predictive of event-specific, alcohol-consumption-related negative consequences, over and above other factors including total drinks consumed. This study highlights the need for more focused BAC education strategies at American universities.
