Abstract
Eleven personality disorder scales for the MMPI, as described in DSM‐III, were derived by Morey and his colleagues from the original MMPI item pool through a combination of rational and empirical strategies. These new scales have enjoyed popularity among clinicians. Normative tables for each of these scales, with and without overlapping items, were constructed from MMPI responses from a large contemporary normal reference sample of adults and adolescents without any physical or mental handicaps who were selected randomly from a three‐state area in the Midwest. Some items from the Morey Personality Disorder scales were deleted during development of the MMPI‐2; separate normative tables have been prepared for the scales so affected, which allows clinicians who are using the MMPI‐2 to continue to use these slightly modified scales.
