College students are considered a population that is especially vulnerable to alcohol-related negative consequences. Current screening tools, which aim to identify individuals who are hazardous drinkers, include Binge Drinking (5 or more alcoholic drinks for men/4 or more alcoholic drinks for women in a two-hour period on one occasion within the previous two weeks) and the Alcohol Use Dependency Identification Test – Consumption (AUDIT-C). While each tool demonstrates high measurement sensitivity, researchers question measurement specificity. Therefore, the purpose of this study is to address the gaps within current measures as it concerns identifying risky drinkers, and to validate a new measure known as Young Adult Risky Drinking (YARD). The specific aim of this study is to test Item Response Theory (IRT) model assumptions and psychometric properties of Construct Validity and Reliability. The instrument was administered via anonymous survey with inclusion criteria consisting of being an undergraduate student at the University of Florida. Participants are asked 84 multiple choice questions which are broken down into various categories: 9 demographic questions, 55 questions regarding drinking behaviors within the last two weeks, and 17 questions regarding major negative health outcomes that have occurred while under the influence of alcohol within the past two weeks.
