✦ Synopsis
Examined the discriminant validity of the MMPI-2 in assessing comorbidity in a posttraumatic stress disorder (PTSD) Vietnam veteran population. The Structured Clinical Interview for the DSM-111-R (SCID) was used to diagnose veterans and to classifi them into four groups: PTSD Only, PTSD with mood disorders, PTSD with other anxiety disorders, and PTSD with mood and anxiety disorders. All groups had clinical elevations on scales E 1, 2, 3, 4, 6, 7, 8, 0, PK, and PS, with peak elevations on scales 8, 7, and 2. The PTSD Only group's MMPI-2 scores were not significantly lower than other groups' scores. The PTSD +MoodlAnxiety group was significantly more elevated on scales 2 and 7 than the PTSD On& and PTSD+Anriety group but did not otherwise show significantly higher scale elevations than other groups. No significant differences existed between groups on scales 8 L, K, PK, and PS.
Implications of these results for PTSD and the current diagnostic system are explored.
