Abstract:
The authors gave the self-report Personality Diagnostic Questionnaire--Revised (PDQ-R) to 87 applicants for inpatient treatment of severe personality psychopathology and, blind to these results, diagnosed personality disorders in the applicants by using the Personality Disorder Examination and the Structured Clinical Interview for DSM-III-R Personality Disorders. The PDQ-R was not a substitute for a structured interview assessment of axis II disorders because many of its diagnoses were false positives. Its high sensitivity and moderate specificity for most of the axis II disorders suggest, however, that it is an efficient instrument for screening patients with DSM-III-R personality disorders.
