The purpose of this study is to compare the accuracy of screening instruments with clinical predictors in the identification of prenatal alcohol use. 350 women initiating prenatal care at the Brigham and Women's Hospital (Boston, MA) completed the T-ACE, AUDIT, and SMAST. The predictive accuracy of each was compared using Receiver Operating Characteristic (ROC) curve analysis. The T-ACE, AUDIT, and clinical predictors alone correctly identified 65 to 70% of current drinkers, whereas the SMAST alone performed only slightly better than chance. The predictive ability of the T-ACE was further improved with the addition of clinical predictors.
