Result of Multiphasic Personality Inventory among People with Scoliosis: Retrospective Cross-Sectional Analysis of Military Candidate in Korea / 신경정신의학

ABSTRACT

OBJECTIVES: The aim of this study was to identify the association between scoliosis and psychopathological effects using the Military Personality Inventory (MPI). METHODS: A retrospective cross-sectional study was conducted of 19-yr-old examinees admitted to the Military Manpower Administration in Korea from February 2007-January 2010. The authors compared the profiles of MPI of 3004 scoliosis cases with the profiles of MPI of 11920 normal controls. The scoliosis cases were classified into two groups according to severity, including mild to moderate, and severe. RESULTS: There was a significant difference between the two groups based on the validity scales. The neurosis scales, including anxiety, depression, somatization and personality disorder, were significantly different between the groups. Concerning the anxiety, depression and somatization subscales, the scores of the mild to moderate group and the severe group were higher than those of the control group. Regarding the personality disorder subscale, the mild to moderate group was higher than the control group. For the paranoid subscale, there was a significant difference between the groups and the mild to moderate group had a higher score than the control group. Furthermore, the partial eta square was 0.018, 0.019, and 0.018 for anxiety, depression, and somatization respectively, which suggests that scoliosis was significantly associated with symptoms of anxiety, depression, and somatization. CONCLUSION: Young men with scoliosis tended to have higher scores concerning the MPI than young men without scoliosis. In particular, the scores were higher for anxiety, depression, and somatization symptoms. This result shows that scoliosis may have psychopathological effects on young men.
