College Drinker’s Check-up (CDCU) is a computer-based, brief motivational interviewing intervention designed to help reduce the use of alcohol by college students (ages 18-24) who are heavy, episodic drinkers (defined as having four or more drinks per occasion for women and five or more drinks per occasion for men at least once in the past 2 weeks with an estimated peak blood alcohol concentration of 0.08 gram-percent or above). CDCU consists of an integrated set of screening, assessment, personalized feedback, and decisionmaking modules and is based on Drinker’s Check-up for heavy-drinking adults. (Drinker’s Check-up was reviewed separately by NREPP.)
