Abstract

The Alcohol Use Disorder Identification Test (AUDIT) is a brief screening instrument for assessing alcohol use problems among adults. This instrument is widely used and continued evaluation of its psychometric performance is needed. Reliability and validity are the primary psychometric characteristics of interest when evaluating psychological instruments. The focus of the present study is on reliability, which reflects the consistency or repeatability of the scores produced by a given instrument. Using meta-analytic methods, results showed that approximately 65% of previously published studies using the AUDIT did not appropriately report reliability estimates. Among the remaining studies, weighted reliability estimate centered on .81 (SD = .07) suggesting that the AUDIT generally produces scores of adequate reliability for most research purposes. Multiple regression equations showed that, among a variety of sample and methodological characteristics, the standard deviation of scores was the only statistically significant predictor of the variability in AUDIT score reliability estimates.
