Differential utility of three indexes of risky drinking for predicting alcohol problems in college students
Abstract
This study evaluated the relationship between alcohol-related problems and 3 indexes of risky drinking in college student drinkers: number of drinks consumed per week, frequency of binge drinking, and estimated blood alcohol levels (BALs). Use of 2 independent samples (N1 = 204, N2 = 181) allowed a cross-validation of obtained associations. Results indicated that neither binge drinking frequency nor BAL were more highly related to alcohol-related problems than was weekly drinking. Furthermore, BAL did not provide unique explanatory power in accounting for alcohol-related problems; mixed results were obtained regarding the relationship of binge drinking estimates with problems.
