Abstract
- OBJECTIVE: The goal of this study was to examine whether MMPI scores could discriminate between normal group and exaggerated pain group and predict treatment prognosis in exaggerated pain group.
METHODS
For psychological evaluation, MMPI was administered to 37 low back pain patients and 36 normal controls. MMPI findings in two groups were compared, using t-test and discriminant function analysis. Nineteen patients of exaggerated low back pain group contacted by telephone were questioned about treatment satisfaction degree. And satisfaction group(9 patients)nd dissatisfaction group(6 patients)s MMPI findings were compared. RESULT: Hy, Hs, D scale scores in exaggerated pain group were higher than in control group. In discriminant function analysis by Hs, Hy, and D, percent of correctly classified 'gouped' cases was 74%. Discriminant function of Hy scale was the highest and that of D scale was the lowest. In satisfaction degree study, no finding was significant.
CONCLUSION
MMPI findings were effective in discriminating between exaggerated pain group and normal control group. Further researches will need more structured and comprehensive approach.
