Objectives: Operational definition and its validated measure of traditional Korean medicine (TKM) are pivotal for research studies and reliable clinics. There have been ten years of clinical studies on Eum-Yang (Yin-Yang) and Sasang typology using Sasang Personality Questionnaire (SPQ) of integrative biopsychology. The objective of this study was to perform a systematic review on the use of SPQ to provide insights and foundation for its further studies and clinical application. Methods: Clinical studies on SPQ were searched using five domestic and foreign research databases. Attained research articles were then subjected to predefined systematic reviews. Demographic characteristics of participants and research topics of articles were described. Psychological and physical features of SPQ and its subscales were reviewed and compiled to reveal biopsychological characteristics. Results: There were 33 articles with 15,085 participants on Eum-Yang (n=19) and Sasang typology (n=14). The SPQ-total score was in an increasing order of So-Eum, Tae-Eum, and So-Yang. Eum-Yang groups were categorized at a 3:4:3 ratio using %ile score of SPQ-total. The SPQ-total showed a significant positive correlation with Novelty-Seeking and a negative correlation with Harm-Avoidance in psychological perspective, while it was not significantly correlated with Body Mass Index or Ponderal Index in physical perspective. The SPQ-total and subscales explained psychopathological characteristics of stress recognition, negative emotion, problem behavior, and depression. Conclusions: The SPQ was found to be an objective biopsychological measure of TKM for Sasang typology and psychopathology. It would provide foundation for 'Korean Psychology' and multidisciplinary studies.

Objectives The Eum-Yang (Yin-Yang in English) temperament was shown to have clinical and structural validity with Sasang Personality Questionnaire (SPQ), however the studies of the association with behavior problems and personality structure in adolescents were not satisfactory. The purpose of this study was to examine the relationships between Eum-Yang temperament and behavior problems in Korean middle school students. Methods 122 first grader of middle school students (68 boys and 54 girls) completed SPQ, Junior version of Temperament and Character Inventory (JTCI), and Youth Self Report (YSR). The correlations between SPQ, JTCI, and YSR subscales were investigated. And, also the differences between SPQ, JTCI, and YSR subscales among Yang (high 30% of SPQ total score) and Eum (low 30% of SPQ total score) temperament groups classified with SPQ total score were examined. Results The SPQ total score were correlated with Novelty-Seeking (r=.321) and Reward-Dependence (r=.392) in boys, and with Novelty-Seeking (r=.427) and Harm-Avoidance (r=-.444) in girls. The SPQ total score were not significantly correlated with Body Mass Index, Ponderal Index and YSR total, however significantly correlated with YSR Internalizing problems and Withdrawal/depressed subscale (r=-.242 and r=-.419) in boys and Withdrawal/depressed subscale (r=-.449) in girls. There were significant differences between Eum and Yang groups in Novelty-Seeking, Harm-Avoidance and Withdrawal/depressed as for boys and girls. Conclusions The biopsychological structure of SPQ was confirmed with middle school students. The behavioral (SPQ-B) and emotional (SPQ-E) perspectives of Eum-Yang were found to be protective and risk factors, and also correlated with Externalizing and Internalizing behavior problems, respectively. The biopsychological characteristics of Eum-Yang temperament and its relation with psychopathological symptoms in late-childhood should be carefully analyzed.

Introduction The purpose of this study was to review thirty years of studies on psychological characteristics of Sasang types to delineate generalizable psychological theories pertaining Sasang typology. Methods Research articles providing psychometric characteristics of each Sasang types were extracted from five database written in Korean and English. Demographic features of the participants, clinical methods for the Sasang type classification, and psychological characteristics of each Sasang types were reviewed and summarized. Results A total of 59 peer-reviewed research articles were found to be published from 1991 to 2018, and the So-Yang and So-Eum Sasang type showed distinctive and contrasting psychological features. The overlap between Eastern and Western psychology in Behavioral Activation and Inhibition System was highlighted as for personality studies, but the anxiety as a pathological factor was not found distinguishable between Sasang types. Discussion The present systematic review provided insight on psychological perspectives of Sasang typology, and would be useful for establishing unique construct of Korean Psychology.

This study was to examine the positive and negative affect related to psychological characteristics of each Sasang types using Positive and Negative Affect Schedule (PANAS) with 78 students from School of Korean Medicine, Pusan National University. After determining the Sasang types by QSCC II, the psychological characteristics of each Sasang types were analysed by PANAS. We did ANOVA analysis with eight related scales and found significant differences between the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $3.18{\pm}2.77$, $10.94{\pm}10.08$) and the So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $5.81{\pm}4.20$, $1.83{\pm}9.17$, respectively) in Positive Affect (PA) (F=3.931, p=0.024), PA-Joy (F=3.991, p=0.023), PA-Interest (F=5.025, p=0.009), NA-Afraid (F=3.118, p=0.050), and Difference between Positive and Negative Affect (DPN) (F=6.355, p=0.003) scores. The post-hoc analysis showed that the Tae-Eum type ($18.71{\pm}8.75$, $6.47{\pm}3.36$, $6.31{\pm}2.47$, $10.94{\pm}10.08$) has significantly higher score than So-Eum type ($13.38{\pm}6.03$, $4.55{\pm}2.23$, $4.19{\pm}2.16$, $1.83{\pm}9.17$, respectively) in PA (p=0.018), PA-Joy (p=0.021), PA-Interest (p=0.017), and DPN (p=0.002) scores. The So-Eum type ($5.81{\pm}4.20$) showed significantly (p=0.047) higher score than the Tae-Eum type ($3.18{\pm}2.77$) in NA-Afraid. Results demonstrated distinct affect profile differences between Tae-Eum and So-Eum Sasang types using PANAS. This study may serve as the foundation in identifying psychological traits of Sasang types, especially regarding the aspect of affect.

Objectives: Although medical typologies based on indigenous biopsychological ideas have been described, their integrity has been questioned due to its theory-driven nature in categorization. Therefore, studies on the Sasang typology, a temperament-based traditional Korean medicine, are needed to examine whether it is possible to classify types of specific biopsychological profiles using data-driven analysis. Methods: Psychological measures of the Eastern Sasang Personality Questionnaire (SPQ) and Western NEO-Personality Inventory (NEO-PI) along with physical measures and Sasang types were acquired from 2,049 participants. Latent groups based on the SPQ and NEO-PI subscale scores were extracted using Latent Profile Analysis. Their psychosomatic features were then compared with those of Sasang types. Results: Three SPQ-based latent groups showed distinctive psychological and physical features consistent with those of Sasang types. However, four NEOPI-based latent groups presented only psychological features. Furthermore, SPQ-High and SPQ-Low latent groups demonstrated similar psychosomatic profiles to those of So-Yang and So-Eum Sasang types, respectively. Conclusions: This study illustrates that biopsychological profiles of Sasang types are supported by psychosomatic features of latent groups based on SPQ of Eastern psychology, signifying that the categorization of Sasang typology have acceptable validity and reliability.

The purpose of this study was to measure circumference of four body parts of each Sasang groups with Bioelectrical Impedance Analysis (BIA), and evaluate its usefulness for Sasang type diagnostic test. We obtained the circumference measures of neck (CN), chest (CC), waist (CW), and hip (CH) of 91 college students using BIA and standardized by sex and age. The validity of Sasang group prediction with CC was evaluated. The Tae-Eum group (104.87${\pm}$5.19, 108.47${\pm}$4.96, 116.00${\pm}$9.39, 110.4${\pm}$5.29. neck, chest, waist and hip, respectively) has significantly (p<0.001) bigger circumferences than So-Yang (97.79${\pm}$3.82, 100.02${\pm}$4.21, 101.02${\pm}$7.88, 101.95${\pm}$4.06) and So-Eum (95.63${\pm}$4.67, 96.93${\pm}$4.80, 97.63${\pm}$7.72, 99.86${\pm}$4.40) groups at very four measures. Discriminant functions with CC can be used for Tae-Eum Sasang type diagnostic test with 91.2% of overall Percentage Correctly Predicted (PCP). Tae-Eum type-specific sensitivity was 73.3% and Tae-Eum type-specific specificity was 94.7%. The strength and weakness of measurement and standardization methods for Sasang type diagnostic test, and the methods for the standardization of physical traits with sex and age were discussed. Our study showed distinctive physical features of Tae-Eum type and the usefulness of BIA for the Sasang type diagnosis.

This study was performed to analize the possibility of validation about Questionaire of Sasang constitution Classification which has been made through several stages for the purpose of promoting the objectivity of Sasang constitutional classification. The results of statistical research about the responses data of Sasang Questionaire are as follow: 1. In the case of mutual relation between the items of the QSCC(Questionaire of Sasang Constitution Classification) and 16PF, every item displaced singnificant result.(in male group) 2. In the investigation to classify the score distribution of Sasang items three groups and analize the gap of mean value in each of 16PF, the characters of each Sasang group were turn out as follows: (1) The Taee-Yang group has extrovert and narcissistic inclination. (2) The So-Yang group shows remarkable extrovert inclination. (3) The Tae-Eum group has hidden fear and introvert inclination. (4) The So-Eum group has revealed physical unstability and introvert inclination. 3. The statistical research of female group didn't display any significant result. It will be necessary to analize the respondent shape of female group and introduce new items to coincident with faminine psychology. 4. In the research using 16PF accompany with QSCC in order to classify the Sasang constitution, the accuracy rate of diagnosis showed inspiring elevation. For that reason, it seems to be desirable to introduce some items of 16PF into QSCC. According to above results, although QSCC contains several problems to be solved, its validity was proved, and the analysis of statistics suggests the possibility to step forward by introducing 16PF in some problems of promoting the accuracy of Sasang Constitutional diagnosis, assuring the objectibity of Sasang constitution classification and so on.

Introduction The previous study showed that the psychological Sasang Personality Questionnaire (SPQ) and physical Body Mass Index (BMI) were clinically useful for predicting Sasang types diagnosed with certified clinical specialist and QSCCII. The purpose of current study was to examine its clinical usefulness using large sized clinical sample. Methods The age, sex, height, weight, circumference of waist and hip, Sasang Personality Questionnaire (SPQ), and Sasang type of 2,049 participants listed on the Korean Medicine Data Center were acquired. The anthropometrics of BMI, Ponderal Index (PI), Waist-Hip Ratio (WHR), and Basal Metabolic Rate (BMR) were calculated. The discriminant analysis using SPQ subscales, BMI, age and sex were performed to predict Sasang types. And, the ANCOVA with age and sex as covariate was also used to examine differences among diagnosed and predicted Sasang type groups in biopsychological features. Results The discriminant analysis showed 82.0% of percentage correctly predicted. And, the biopsychological characteristics of predicted Sasang type groups were significantly similar to those of diagnosed Sasang type groups. In both predicted and diagnosed Sasang type groups, the anthropometric measures were in increasing order of So-Eum, So-Yang, and Tae-Eum types, and the psychological measures were in increasing order of So-Eum, Tae-Eum, and So-Yang types as shown in previous studies. Discussion and Conclusion The well validated biopsychological variables of SPQ and BMI showed theoretical and clinical usefulness, and were found to be useful for diagnosing Sasang types in clinical setting. The current study might be useful for the East-West integrative medicine and evidence-based teaching.

In Sasang constitutional medicine, both disease susceptibility and drug response are considered to be related to the characteristics of an individual's physiology and psychology: a theory which is central to traditional Korean medicine. Based on such observable characteristics, Sasang constitutional medicine classifies people into four constitutional types. Genetic studies of Sasang constitution would help reveal the inheritance patterns and models of the typological traits and, moreover, help with traditional medical diagnosis and treatment. To investigate the heritable aspect of Sasang constitution, we collected various pedigrees from South Korea. The study population has 101 pedigrees composed of 593 individuals. The determination of the Sasang constitution type of each individual was performed by doctors who diagnose the Sasang constitutional type of individuals as part of their professional practice. We calculated estimates of familial correlation and heritability. Parent-Offspring pairs showed the strongest familial correlation of Sasang constitutional type, with the correlation values of 0.21 and 0.28, followed by sibling pairs with the value ranging between 0.14 and 0.25. From the heritability analysis conducted with the Variance-Component method, the heritability of TE (Tae-Eum) type, SY (So-Yang) type, and SE (So-Eum) type were 55%, 41%, and 47%, respectively. This pattern of heritability was consistent with different set of analyses, which suggest the robustness of our result. Our result clearly shows that the Sasang constitution type is heritable, and further genetic analysis based on our result will shed light on the biological mechanism of Sasang constitution.
