Gender, injury status and acculturation differences in performance of screening instruments for alcohol problems among US Hispanic emergency department patients.

The sensitivity and specificity of several screening instruments including the CAGE, brief MAST, AUDIT, TWEAK, RAPS, and Trauma Scale, were evaluated against both ICD-10 and DSM-IV criteria for alcohol dependence and for harmful drinking and abuse in a probability sample of 586 Hispanic emergency department patients. Screening instruments were not as sensitive for females as for males, for those in the low acculturation group, or for non-dependent drinkers. Acculturation was positively associated with the likelihood of being a current drinker and among current drinkers, was positively associated with alcohol dependence and with harmful drinking or alcohol abuse.
