Minnesota Multiphasic Personality Inventory(MMPI) Responses of Posttraumatic Stress Disorder

This study was attempted to identify MMPI responses which significantly discriminate between the PTSD and the normal on the basis of MMPI scores. And it was designed to classify the types of MMPI profiles in the PTSD. Subjects were 55 healthy control and 45 PTSD who were inpatient or outpatient in Presbyterian Medical Center from Januaiy, 1991 to March, 1993. The results were as follows: 1) In MMPI subscales, except L scale, PTSD had significantly higher score than the normal group. 2) In discriminant analysis, it was D, Mf, Pt, ans Si that discriminate these two groups. Also, it classified 88.9% of PTSD group and 94.5% of normal group correctly. 3) Three subgroups were extracted from the PTSD by cluster analysis of MMPI. a. The first subgroups(54.3 %) showed a profile which T score of L, F scale configured a reverted V” pattern, and T scores of Hs, D, Hy, Pd, Pt, and Sc scale belonged to the range of 60 to 71 point. b. The second subgroup (36%) showed a normal profile which had L, F，and K scale with normal range of 47 to 56 T score and all clinical scales with 42 to 59 T score. c. The third subgroup(ll.l%) showed a profile which had L, F, and K scale belonged to the range of 56 to 70 T score and all clinical scales belonged to the range of 60 to 80 T score except M f scale. These findings suggest MMPI has a remarkable discriminant power in PTSD group
