[Cluster analysis of alcoholic patients based on personality variables, social insecurity and control orientation]

200 alcoholics from 6 clinics with different therapeutic orientations were tested with the Freiburg Personality Inventory (Fahrenberg et al. 1978), an assertiveness-inventory (Ullrich u. Ullrich 1977), and a translated version of the Levenson (1973)-Locus of Control. On the base of a hierarchical-agglomerative cluster analysis four types of patients were suggested: 1) An aggressive-depressive, 2) a depressive-social anxious external controlled, 3) an assertive, 4) and a high stable alcoholic with well-balanced mood and internal control. The highest changes of generalized variance in a stepwise discriminant analysis were found on depression, misfortune-anxiety, impulsivity and control by powerful others. The reclassification rate was 85.5%. Out of 24 biographical data no one differed between the groups. The hypotheses of a population variation over different clinics was not supported. Differential therapeutic indications for the groups were discussed.
