A Study of Active Duty Military Personnel With the MMPI-2

The Minnesota Multiphasic Personality Inventory (MMPI) has a long history of application in military settings. Our investigation is an exploration of the relevance and appropriateness of the revised version of this instrument, the MMPI-2, in military settings. The question of whether special norms are needed for use in the military was addressed. Results showed that military personnel (N = 1,156 men from the Army, Navy, Air Force, and Marine Corps) responded, as a group, in a manner similar to the MMPI-2 restandardized sample. Similar mean scores and factor structures were obtained. Age effects were also studied. Consistent with past research, there were clear age differences on the MMPI-2 with younger subjects producing more scale elevation, particularly on the Psychopathic Deviate (Pd), Psychastenia (Pt), Schizophrenia (Sc), and Hypomania (Ma) scales. The results of the study show that special norms for military settings are not needed.
