Objective : The purpose of this study is to investigate the differences of affective and cognitive characteristics in depressive patients according to the severity of somatization, and to find the association of these factors on the severity of somatization.
Methods : 86 patients with depressive disorders who had somatic discomfort without clinically significant medical illness were enrolled. The following measures were used : 1) Patient Health Questionnaire-15 (PHQ-15), 2) Beck Depression Inventory (BDI), 3) State-Trait Anxiety Inventory (STAI), 4) Toronto Alexithymia Scale-20-K (TAS-20-K), 5) Symptom Interpretation Questionnaire (SIQ). Patients were divided into two groups: mild to moderate somatization group as a score of ≤10, severe somatization group as a score of ＞11 on PHQ-15. The scales were compared with each group.
Results : The mean score of BDI in severe somatization group were significantly high. The score of total, subscale 1 (?Difficulties identifying feelings’) and 2 (?Difficulties describing feelings’) in TAS-20-K and the scores of total, psychological, physical and catastrophic interpretation in SIQ were significantly high in severe somatization group. Finally, results of logistic regression showed that subscale 1 (?Difficulties identifying feelings’) in TAS-20-K and physical interpretation in SIQ had significantly influence on the severe somatization.
Conclusion : Among all variances, ‘difficulties identifying feelings’ and ‘physical interpretation’ were the most influential predictors for the severe somatization. These results suggested that therapeutic approach based on these characteristics according to the severity of somatization could be important for the management of somatizer.
