Correlates of the Michigan Alcoholism Screening Test (MAST) among DWI offenders.

Examined the relationship between scores on the Michigan Alcoholism Screening Test (MAST), Psychological Screening Inventory (PSI) and Locus of Control Scale (LOC) in a selected sample of 156 apprehended drunken drivers. About 90% were identified as problem drinkers on the MAST, and 15% were screened by the PSI as requiring more intensive psychological assessment. Scores on the MAST were independent of LOC, but positively related to results on PSI scales that assess antisocial acting-out and neurotic anxiety and also to general maladjustment (mean scale elevation). A weighted composite of three PSI scales was related significantly to MAST scores, but explained only a modest proportion of variance in them. The MAST and PSI can be used to supplement one another in screening DWI offenders.
