Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical scale elevations were examined through retroactive analysis of comprehensive posttraumatic stress disorder (PTSD) evaluations of military veterans. Clinical scale elevations and MMPI-2 codetypes were compared across samples organized by the era in which the veterans served. Mean and mode codetypes were then compared to standards outlined by Watson et al.’s (n.d.) Best Practice Manual for Posttraumatic Stress Disorder (PTSD) Compensation and Pension Examinations for the U.S. Department of Veterans Affairs. Mean codetypes of the sample were largely consistent across service eras with the expected 28/82 MMPI-2 codetype outlined by Watson et al. However, modal codetypes varied significantly within and across service eras. The mode codetype findings are consistent with other literature indicating mean codetypes are often consistent with the Watson et al. standards, however, the expected codetypes do not occur frequently enough to be statistically meaningful within any service era examined.
