CAGE as a predictor of hazardous alcohol consumption in U.S. Army personnel

Sensitivities, specificities, and odds ratios for hazardous drinking for various cut scores on the CAGE are computed for a large sample active duty Army personnel. Contrasts on these properties are made between the standard CAGE and a "modified CAGE" consisting of standard CAGE items and two other items dealing with problematic drinking. The role of demographic variables--gender, ethnicity, marital status, rank category, and age in mediating relationships of both versions of the screening test to hazardous drinking--is also explored. At a cutoff score of one endorsed item, odds ratios were highest for female personnel and commissioned officers.
