FREQUENCY OF PERSONALITY-DISORDERS IN PATIENTS WITH PSYCHOTIC DISORDERS

Twentyone patients with psychotic disorders completed the SCID Screen questionnaire and were interviewed by means of the Structured Clinical Interview for DSM-III-R. The Cohen's kappa of agreement between the methods was 0.50 and as concerns specific personality disorders 0.37. The SCID Screen questionnaire was somewhat overinclusive. The sensitivity was 100% while the specificity was 43%. In a series of 58 patients with psychotic disorders, 72.4% had at least one personality disorder. Paranoid, avoidant, dependent and obsessive-compulsive personality disorders were the most frequent. The results indicate that personality disorders according to DSM-III-R, Axis II can be identified in patients with psychotic disorders, that the SCID Screen questionnaire can be used in this patient sample and that there is a high frequency of personality disorders in patients with psychotic disorders.
