Measuring excessive alcohol use in college drinking contexts: the Drinking Context Scale.

Research on youthful drinking has shown that the greatest risks associated with alcohol abuse are related to contextual factors that may potentiate heavy drinking as well as increase risks for adverse consequences. These contextual factors include interacting psychological, interpersonal, and environmental dimensions of alcohol use. However, despite considerable college drinking research to identify these factors, few formal instruments have been produced for measuring excessive drinking in multidimensional contexts. The current study of 197 college students who were cited their first time for breaking university drinking rules focuses on the development and validation of a scale for measuring the likelihood of excessive drinking across an array of psychological, interpersonal and situational contexts resulting in the 23-item Drinking Context Scale (DCS). Three distinct factors emerged defining Convivial drinking, Private Intimate drinking, and drinking as a form of Negative Coping. These three factors explained 61.5% of the variance after principal components analysis and varimax rotation, showed excellent internal reliabilities, and were moderately intercorrelated. MANOVA analysis demonstrated concurrent validity with the Quality Frequency Index (QFI) and a modified version of the Michigan Alcoholism Screening Test (MAST). Implications for further research with the DCS are suggested.
