Objectives: The goal of the present study was to elucidate the characteristics of behavior problems in Sasang typology with child patients.

Methods: Subjects consisted of 176 (95 boys, 81 girls) children from 36 months to 83 months were diagnosed by two clinical experts in pediatrics and Sasang medicine. There were 22 So-Yang types, 141 Tae-Eum types, and 13 So-Eum types. The behavior problems were measured with Child Behavior Checklist (CBCL) and ANOVA (analysis of variance) was used for the analysis.

Results: There were no significant differences between Sasang types among subject’'s age (F(2, 173)=.190, p=.827) and sex (χ2(2, N=176)=1.639, p=.441) as well as their mother’ age (F(2, 169)=.060, p=.942) and education level (χ2(4, N=172)=.394, p=.983) and their father’ age (F(2, 168)=1.184, p=.309) and education level (χ2(4, N=172)=5.664, p=.226). So-Yang types (50.14±22.35; 17.27±8.60) had higher scores than Tae-Eum types 38.74±21.32; 12.62±7.98) in total problems and internalizing problems score of the CBCL, respectively. More specifically, So-Yang types (5.90±2.81; 3.77±1.90) had significantly higher depression/anxiety and somatization subscale score than Tae-Eum types (4.04±2.73; 2.30±2.12). Scores of So-Yang types were significantly higher than those of CBCL clinical group in depression/anxiety and somatization subscales.

Conclusions: There were significant differences between child outpatients with different Sasang types, which would be taken into consideration concerning development of Sasang type diagnosis in addition to parenting, treatment, and prevention for children.
