✦ Synopsis

A total of 73 psychiatric inpatients, all of whom (but two) ful®lled criteria for at least one speci®c personality disorder (PD) on SCID-II PQ, were interviewed with the help of PDE. The self-report PD diagnosis was con®rmed in 35 (48 per cent) patients. The diagnostic agreement between the two instruments was poor, yielding an overall weighted kappa of 0.22. Levelling o the PD base rates by increasing or decreasing the diagnostic threshold of SCID-II PQ and PDE respectively increased the overall weighted kappa to 0.38 in both instances. 70 per cent of SCID-II PQ but only 29 per cent of PDE personality disorders were of extensive type. Most frequent important co-occurrences occurred between individual PD types within cluster 2. On the whole, the results con®rmed the relatively poor agreement between self-report and interview PD diagnoses. The utilization of self-report questionnaires in a clinical practice remains a controversial issue.
