Description
Summary:ABSTRACT Criteria to differentiate personality disorder from extremes of normal personality variations are important given growing interest in dimensional classification because an extreme level of a personality dimension does not necessarily indicate disorder. The DSM‐5 proposed classification of personality disorder offers a definition of general personality disorder based on chronic interpersonal and self/identity pathology. The ability of this approach to differentiate personality disorder from other mental disorders was evaluated using a self‐report questionnaire, the General Assessment of Personality Disorder (GAPD). This measure was administered to a sample of psychiatric patients (N = 149) from different clinical sub‐sites. Patients were divided into personality disordered and non‐personality disordered groups on the basis of the Structured Clinical Interview for DSM‐IV Axis II Disorders (SCID‐II). The results showed a hit rate of 82% correct identified patients and a good accuracy of the predicted model. There was a substantial agreement between SCID‐II interview and GAPD personality disorder diagnoses. The GAPD appears to predict personality disorder in general, which provides support of the DSM‐5 general diagnostic criteria of personality disorder. Copyright © 2012 John Wiley & Sons, Ltd.
