Abstract
A SECONDOR factor analysis was performed on the Michigan Alcoholism Screening Test (MAST) items endorsed by 200 repeat driving under the influence of alcohol (DUI) offenders and nonviolent felony offenders. The result of the factor analysis showed a higher-order general factor measuring general alcohol dependence as well as several more primary dimensions of alcohol abuse and/or alcoholism such as (a) psychoactive substance dependence, (b) denial, (c) antisocial drinker, (d) discord, and (e) vocational impairment. Thompson's SECONDOR factor solution provides empirical support for the literary controversy that the MAST measures both unidimensional and multidimensional signs and symptoms of alcoholism.
