Abstract
The Michigan Alcoholism Screening Test (MAST) was validated on a wide range of USA drinkers. In this study the MAST was administered to 4 groups of New Zealand males: 100 hospitalized alcoholics, 100 psychiatric inpatients, 70 convicted drinking drivers and 55 social drinkers. All the diagnosed alcoholics scored in the test''s alcoholic range, as did 83% of the drinking drivers. Of psychiatric patients, 76%, and of social drinkers, 89% scored below 5. The MAST appears to be a valid instrument for use under New Zealand conditions, but the ability to discriminate between alcoholics and problem drinkers would be an added advantage.
