Measuring college student drinking: illustrating the feasibility of a composite drinking scale.
This study explored the feasibility of a Composite Drinking Scale (CDS) designed to capture fully the phenomenon of problem drinking among college students while allowing easy public understanding. A survey conducted at 32 four-year U.S. colleges included four consumption measures: 30-day frequency; average number of drinks per week; number of drinks usually consumed when partying; and greatest number of drinks in one sitting in the past two weeks. Responses were normalized and added to create a continuous distribution, which was then subdivided into quartiles (CDS/Q1-Q4). The CDS is an easily understood scoring system, but compared to the simplistic "binge drinking" measure, it captures a broader range of relative risks and more clearly establishes the quadratic relationship between consumption and alcohol-related problems. Development of the CDS will require further exploring the best set of questions to include, establishing U.S. norms for the general population, and then transforming those scores to a simple measurement yardstick whose meaning can be easily communicated to the public.
