PERSONALITY-DISORDERS AND RELATIONSHIP TO PERSONALITY DIMENSIONS MEASURED BY THE TEMPERAMENT AND CHARACTER INVENTORY IN PATIENTS WITH OBSESSIVE-COMPULSIVE DISORDER

The occurrence of personality disorders was investigated in 36 patient s with obsessive-compulsive disorder by means of the SCID Screen quest ionnaire. In addition, the personality dimensions were explored by mea ns of the Temperament and Character Inventory (TCI). In total, 75% of the patients fulfilled the criteria for a personality disorder accordi ng to the SCID Screen questionnaire, mostly (55 %) within cluster C. S everal significant correlations were found between the separate person ality disorders (PD) and subscales of the TCI, the most pronounced bei ng between avoidant and obsessive-compulsive PD and novelty-seeking an d self-directedness. Strong correlations were also found between self- directedness and paranoid and borderline PD. In multiple regressions w here the presence of PD in clusters A, B and C, respectively, were use d as dependent variables and where the separate subscales of the TCI w ere used as independent variables, the multiple R reached 0.68, 0.76 a nd 0.80 in clusters A, B and C, respectively. Thus 46-64% of the varia nce in the personality disorder clusters could be explained by the TCI subscales.
