Multiphasic personality inventory on pneumo-or hemo-thorax: Retrospective cross-sectional analysis of military candidate in Korea

Abstract

Objectives

The aim of this study was to identify association between pneumo- or hemo-thorax and psychological distress using the Military Personality Inventory (MPI).

Methods

A retrospective cross-sectional study was conducted with 19-yr-old examinees who were admitted to the Military Manpower Administration in Korea from February 2009 to January 2010. A total number of 1955 young men were enrolled in this study. The normal volunteer group (n = 1561) comprise individuals who did not have pneumo- or hemo-thorax. The pneumo- or hemo-thorax group (n = 394) included individuals with pneumo- or hemo-thorax. This group was divided into two subgroups, group A (treated with conservative care or chest tube insertion, n = 341) and group B (treated with wedge resection, n = 53).

Results

We compared each of three groups (Control group, Group A, Group B) using the analysis of covariant (ANCOVA). The somatization subscale score of the neurosis category was significantly higher for group A (P < 0.001) and showed higher tendency for Group B than the control group (P = 0.073). The other categories (validity scale; anxiety, depression, and personality disorder subscales for neurosis scale; and psychopath scale) showed no significant difference in the MPI among Group A, Group B and Control group.

Conclusion

Conservative care or chest tube insertion group had higher somatization symptoms than control group. Wedge resection group had higher somatization tendency than control group. Individuals with pneumo- or hemo-thorax history may be concerned about their body shape or their general condition. Therefore, supportive intervention and psychiatric education may be needed for them to relieve somatic distress.
