The Alcohol Use Disorders. Identification Test (AUDIT) score is useful for predicting alcohol consumption.

Abstract

It is important to screen for alcohol consumption and drinking customs by using a stan- dardized method. The aim of this study was to investigate whether standardized questionnaire was useful for predicting alcohol consumption. A cross-sectional study using the Alcohol Use Disorders Identification Test (AUDIT) was conducted in 334 outpatients who consulted the Internal Medicine Department of Osaka City Juso Hospital. The patients completed self-reported questionnaires and underwent a diagnostic interview, physical examination, and laboratory testing. Forty (23%) male patients reported daily alcohol consumption 40 g, and 16 (10%) female patients reported consumption 20 g. The optimal cutoff values of hazardous drinking (all patients)/ drinker (male)/ drinker (female) were calculated using a 10-fold cross validation, resulting in an optimal AUDIT score cutoff of 8.2/ 7.2/ 6.1, with sensitivity of 95.5%/ 96.3%/ 88.9%, specificity of 87.0%/ 96.3%/ 88.9%, false positive rate of 13.0%/ 9.4%/6.6%, false negative rate of 4.5%/ 3.'%/ 11.1%, and area under the receiver operating characteristic curve of 0.97/ 0.98/ 0.99. In conclusion, this study showed that the AUDIT score was useful for predicting alcohol consumption.
