Abstract

|
The MMPI (Minnesota Multiphasic Personality Inventory) has been used frequently in eval ating psychologiiral factors which play an important role in determining the nature and course of low bac pain, and for comparison with clinical findings.
In this study the MMPI was applied to 79 patients who were admitted due to organic low bac pain and 35 control subjects.
Results of the MMPI were analyzed and compared with patient´s general characteristics, clinical findings and treatment results.
The major results are as follows:
1. Mean T-score of hypochondriasis (Hs) scale, depression (D) scale and hysteria (Hy) scale of ,4MPI were 59.7, 55.9 and 59.6 respectively, which were significantly higher than that of control gorup (p<0.01). For the chronic patients whose symptoms had been present for 6 months or longer, the mean T-score of hypochondriasis scale, depression scale and hysteria scale of MMPI were significantly higher than that of the acute patients whose symptoms had been present for less than 6 months (p<0.01).
3. At the time of discharge, 74.7% of all patients showed favorable results and 95% showed symptomatic improvement. There was significant correlation between treatment results and each of the hypochondriasis; depression and hystera scales of MMPI (p<0.01).
4. The average hospital stay was 23.6 days. There was no significant correlation between hospital days and the T-scores of the neurotic triad.
5. Characteristics of the 3 litigation cases in the patient group were studied which revealed generally
unfavorable treatment results, longer hospital days and higher T-scores of hypochondriasis, depres
sion, hysteria, paranoia, psychasthenia, schizophrenia and social introversion scales.
According to the above results, MMPI is considered as a useful test in evaluating psychological factors in comprehensive rehabilitative treatment of low back pain.
