Development and validation of a new procedure for the diagnostic assessment of personality disorder: the Multidimensional Personality Disorder Rating Scale (MPDRS).
Data from a community-based prospective longitudinal study were used to investigate the utility of a structured assessment of the DSM-IV General Diagnostic Criteria for a Personality Disorder (PD). The Structured Clinical Interview for DSM-IV PDs (SCID-II) was administered to 154 adults. After completing the interview, an experienced clinician assessed the General Diagnostic Criteria for a PD using a structured rating scale. PD diagnoses, based solely on the rating scale data, demonstrated strong agreement with diagnoses obtained using the diagnostic thresholds for specific PDs (Kappa = 0.89). The sensitivity, specificity, predictive power, and internal reliability of the rating scale were satisfactory. PD diagnoses, based on both of the assessment procedures, were associated with substantial impairment and distress. These findings suggest that a structured assessment of the DSM-IV General Diagnostic Criteria for a Personality Disorder may constitute a useful alternative or supplement to standard assessments of the diagnostic thresholds for specific DSM-IV PDs.
