Multivariate classification of alcoholics by means of the MMPI.

Performed a multivariate correlation grouping technique on the clinical and validity scales of the MMPI over 2 independent samples composed of 481 hospitalized alcoholics. 4 alcoholic types were identified and, from actuarial studies of the MMPI, all appeared to be addictive personality patterns. The most common type was characterized by poorly controlled anger and other open forms of emotional expression in frustrating situations. (19 ref.)
