Abstract:This document summarizes the results of a validation study for five adult screening instruments in use for preliminary screening of driving while intoxicated (DWI) offenders for problem drinking. The instruments were the Driver Risk Inventory (DRI), the Michigan Alcohol Screening Test (MAST), Mortimer-Filkins Questionnaire (without the interview) and the Substance Abuse/Life Circumstance Evaluation (SALCE). As an additional task, the project was asked to validate a combination of the consumption questions from the Alcohol Clinical Index and the four CAGE questions. A criterion instrument (the Comprehensive Adult Interview) was developed during the project by a panel of acknowledged leaders in the field of problem drinking assessment. All of the screening instruments (six in total) were administered to 609 consenting adult DWI program participants in Pennsylvania and Massachusetts. The assessment instruments correctly identified problem drinkers, as classified by the criterion instrument, across a range of 72% to 92% of the time. In general, the more sensitive an instrument was, the less specific it tended to be. In other words, a cost of identifying a higher proportion of the problem drinkers was that more persons who were not problem drinkers were incorrectly classified as such. /Abstract from report summary page/
