Objectives ~ To search for the character of subjective symptom among traumatic brain injury patient, we tried to investigate the level of subjective symptoms and the character of the discrepancy between subjective symptoms and suggested disability. The factors s~~ch as demographic factors, characteristics of head trauma, the score of neuropsychological test and MMPI were compared for those subjective symptoms.
Methods :SCL-90-R, K-WAIS, K-Iv1AS, K-BNT and MMPI was conducted for 281 patients who are suitable for this study with age over 18, out of 498 patients who visited hospital for their psychiatric symptoms after traumatic brain injury or disability evaluation after rE;questing consult from Mar 1, 1999 to Aug 31, 2003. Subjects were categorized based on the positive symptom total in SCL-90-R as four groups such as rriinimal distress group to observe character depending on the subjective symptoms level. Mild distress group, moderate distress group, and severe distress group and compared with failed group which couldn´t perform SCL-90-R. And 180 patients of all of tests ´conducted, were divided to the three groups such as no difference group, faking good group, and faking bad group by comparing the level of subjective symptoms to suggested disability and assessed its results.
Results : In the result of SCL-90-R depending on the subjective symptom level, there was significant difference (p<.001) in subscale and global index of SCL-90-R. There was also significant difference(p<.001) in the division depending on the discrepancy between subjective symptoms and suggested disability on subscale and global index in each group. However, the score in phobic anxiety scale was high other than subscale score. The result of neuropsychological test depending on the level of subjective symptoms represented more severe in subjective symptoms anti lower in intelligence after traumatic brain injury. But, even or better intellectual capability was possessed in faking good group by comparing to no difference group. Memory ability is reduced as subjective symptoms severe and faking good group was superior in its performance. The same result was shown in K-BNT. Regardless of the level of subjective symptoms or discrepancy of the subjective symptoms between suggested disability, traumatic brain injury atients (except the group appealed minima! distress) experienced basic neurotic symptoms and they appealed psychotic symptoms as the level of subjective symptoms is severe in MMPI.
Conclusion:In this research, All the patient commonly have experienced neurotic symptom weather the symptom
of traumatic brain injury patients is seve~e or not. Psychotic symptoms was mainly used for the faking bad of symp-
tom and prove~~ that they underestimated their psychiatric symptoms with better cognitive function level after traumat c brain injury.
