Description
Summary:A total of 73 psychiatric inpatients, all of whom (but two) fulfilled criteria for at least one specific personality disorder (PD) on SCID‐II PQ, were interviewed with the help of PDE. The self‐report PD diagnosis was confirmed in 35 (48 per cent) patients. The diagnostic agreement between the two instruments was poor, yielding an overall weighted kappa of 0.22. Levelling off 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 confirmed 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. © 1998 John Wiley & Sons, Ltd.
