Abstract

Objectives : Illness behavior is defined as the persistence of an adaptive/maladaptive mode of perceiving, evaluating and responding to health status and symptoms according to the status. In a cognitive aspect, somatizing symptoms are regarded as being originated from distortions, including magnification and/or amplification, of perceiving, evaluating and responding to symptoms such as bodily sensations. That is somatization may be explained by maladaptive illness behavior. In this study, we tried to investigate differences of illness behavior in depressive patient according to the presence of somatization.
Methods : We divided 45 patients who were diagnosed as depression with ICD-10 diagnostic criteria into two groups(somatizing and non-somatizing group) according to the somatization subscale of Korean Depression Scale and compared two groups in the differences of illness behavior using the Illness Behavior Questionnaire.
Results : Somatizing group showed significantly higher scores than non-somatizing group on the disease affirmation subscale( vs. 4.76, p=0.003) and the denial subscale( vs. , p=0.006). There were no significant differences between two groups on the general hypochondriasis subscale and the affective unstability subscale. In a logistic regression analysis, somatizing group also showed higher odds ratio (OR) scores on the disease affirmation subscale(OR=1.418, p=0.089) and the denial subscale(OR=1.880, p=0.083).
Conclusion : The disease affirmation and denial may be a discriminative mechanism of somatization in depressive patients. These subscales of Illness Behavior Questionnare could be useful markers, and psychiatric illnesses with somatizing and depressive symptoms may be differentially diagnosed and be predicted through these subscales.
