To the Editor: In their study of alcohol use and alcohol-related problems before and after military combat deployment, Ms Jacobson and colleagues1 assessed the history of potential alcohol dependence using the presence of at least 1 item from the CAGE (cut back, annoyed, guilty, eye opener) questionnaire at baseline. The CAGE questionnaire is a brief valid screening tool for detecting alcohol use disorders, widely used in screening patients for alcohol abuse or dependence in the general population as well as in clinical studies.2 A review concluded that the CAGE questionnaire had greater accuracy than other screening instruments for alcohol use disorders in primary care.3
