Abstract
Minnesota Multiphasic Personality Inventory-2 (MMPI-2) overlapping and nonoverlapping scales were demonstrated to perform comparably to their original MMPI forms. They were then evaluated for convergent and discriminant validity with the Million Clinical Multiaxial Inventory-II (MCMI-II) personality disorder scales. The MMPI-2 and MCMI-II personality disorder scales demonstrated convergent and discriminant coefficients similar to their original forms. However, the MMPI-2 personality scales classified significantly more of the sample as Dramatic, whereas the MCMI-II diagnosed more of the sample as Anxious. Furthermore, single-scale and 2-point code type classification rates were quite low, indicating that at the level of the individual, the personality disorder scales are not measuring comparable constructs. Hence, each instrument is providing similar and unique information, justifying their continued use together for the purpose of diagnosing personality disorders.Keywords
