The Rost and CAGE alcohol screening instruments were compared in a random sample of 103 of 3609 young adults participating in a longitudinal panel. Rost (t = 6.01, df = 101, p<.001) and CAGE (t = 7.27, df = 97, p<.001) scores were significantly higher for those classified as having alcohol dependence than for those without dependence according to the short-form of the Composite International Diagnostic Inventory (SF-CIDI). The areas under the curve for the CAGE (0.840) and the Rost (0.783) were not statistically different (z = 1.30, p>.05).
