The diagnosis of personality disorder: a comparison of MMPI profile, Million Inventory, and clinical judgment in a Workers' Compensation population.
This study investigated information derived from a group of 100 Workers' Compensation cases and used clinical opinion and psychological testing to determine the presence and nature of personality disorder diagnosis. Tests used were the MMPI and the Millon Clinical Multiaxial Inventory. Patients were divided according to categories of presenting complaint. Significant differences were found on both the MMPI and the Millon among the diagnostic groups of personality disorders. The authors cautioned about the use of the Millon Test because of the extremely high numbers of personality disorders suggested by that test. In the discussion, attention was called to the complexities of personality disorder diagnosis when Axis I and Axis II diagnoses are present.
