Objectives : Sasang typology is extensively studied for the Sasang constitution diagnosis objectification with various data, for example, questionaires, reference materials, etc and analyzed with the several statistical methods. In this study, we used ROC-curve (Receiver Operating Characteristic curve) analysis to diagnose Sasang constitution, which is a kind of epidemiologic research methods and is away from traditional statistical methods. Methods : We collected personality questionnaire which consists of 15 items, from 24 oriental medical clinics. We analyzed the sensitivity and specificity using ROC curve method based on the score of personality questionnaire and also investigated classification accuracy and cut-off value of Sasang constitution. Results : The AUC (area under the ROC curve) value was 0.508 (p=.5511) for Taeeumin, 0.629 (p<.0001) for Soeumin and 0.604(p<.0001) for Soyangin, respectively. so the classification accuracy for Soeumin was highest Soeumin for over 30 points and Soyangin for below 28 points respectively. Conclusions : We suggest that Taeeumin is not classified easily in the ROC-curve analysis. We may classify Soeumin and Soyangin but the accuracy of Sasang constitutional diagnosis is still low.

Objectives : The purpose of this study was to validate the Sasang Personality Questionnaire (SPQ), based on the diagnosis of Sasang constitutional medicine clinical specialist. Methods : We performed Sasang type differentiation of 103 college students by certified specialist, and analyzed biopsychological traits of each groups with SPQ, Temperament and Character Inventory (TCI), Positive and Negative Affection Schedule (PANAS) and Body Mass Index (BMI). Results : The SPQ score of So-Yang ($33.1{\pm}0.79$), Tae-Eum ($29.03{\pm}0.67$) and So-Eum ($25.76{\pm}0.98$) Sasang groups showed significant differences from each other. The SPQ showed significant correlation with TCI Novelty-Seeking (r=.346), TCI Harm-Avoidance (r=-.348) and TCI Persistence (r=.346). But the BMI and PANAS did not show significant correlation with SPQ, although the PANAS Positive Affection (r=.332) has significant correlation with SPQ-Behavior. Conclusions : We confirmed the clinical validity of SPQ with clinical specialist and established biopsychosocial instruments. This study would contribute to a more objective diagnosis and studies on biopsychosocial mechanism of Sasang constitutional medicine.

The data were collected from March 10 to April 13. 2002 using a structured questionnaire. The instrument for this study were QCSSII (Questionnaire for Sasang Constitution Clsssification II) by Kim et al.(1996), and the Revised Type A/B personality by Eysenck & Fulker(1983). The data were analyzed through the SPSS 10.0 for Windows program using frequency, percentage, $x^2$-test, ANOVA, and Pearson correlation coefficient. Results: The results of the study are as follows : 1. Of 113 Korean adults, the portion who were Taieum-in, Soeum-in, Soyang-in was 39.8%, 34.5%, 25.7% respectively. 2. For type A/B personality, mixed type was most common, 19.4% of the participants were of type B and 8.0%., type A. 3. For type A/B behavior, mixed type was most common at 47.8% and type A was 2.7%. 4. There were statistically significant differences in the Sasang constitutional type according to BMI (F=14.542, P<.001), and alcohol consumption (F=4.256, p<.018). 5. There were significant difference between type A/B Personality and BMI (F=3.592, P<.032). 6. The data shows correlations between BMI and amount smoked per day (r=2.74, P<.004), between BMI and alcohol consumption (r=-.303, p<.008), between BMI and Sasang constitutional type (r= -.592, p<.0001), between BMI and type A/B personality (r=285, p<.011), between amount smoked per day and alcohol consumption (r= .-361, p<.001). between alcohol consumption and Sasang constitutional type (r=-.306, p<.019). between perceived health state and type A/A personality (r= .246, p<.011). Conclusion: According to the above findings, it can be concluded that further research is need to understand the Sasang constitution for the discipline of Nursing and for nurses to prepare nursing protocols relevant to Sasang constitutional care. Also, Sasang constitution has to be considered in research and practice in the health care delivery system.

Introduction Cloninger's Novelty-Seeking (NS) and Harm-Avoidance (HA) were found to be the biopsychological characteristic of Sasang typology, and the So-Yang type has high NS and low HA however the So-Eum type as contrary. The purpose of this study was to show the clinical usefulness of these measures as objective clinical index of Sasang typology in foreign countries lacking validated measures. Methods The Sasang type of 103 university students was diagnosed using Questionnaire for Sasang Constitution Classification (QSCC) II and clinical specialist, and biopsychological and physical features with NS, HA, Sasang Personality Questionnaire (SPQ) and BMI. These measures were normalized to make a noble index of 'NS(100-HA)', and the correlation among these were examined with Pearson's correlation. The differences of biopsychological and physical features between Sasang type groups were attested with ANCOVA, and the comparison of clinical usefulness of SPQ and NS(100-HA) were examined with discriminant analysis. Results SPQ and BMI were clinically useful for Sasang typology as shown in previous studies, and the substitution of SPQ with normalized NS(100-HA) was found acceptable. The NS(100-HA) is significantly correlated with SPQ (r=0.466, p<0.01), however not with BMI (r=0.079, ns). The SPQ and NS(100-HA) scores were found to be distinctive between Sasang type groups, and these were found to predict Sasang type of participants with similar correctness. Discussion and Conclusion The current study reviewed the theoretical backgrounds and confirmed the clinical usefulness of Cloninger's biopsychological theory in Sasang typology. These might provide foundations for integrative medicine and cross-cultural biopsychology of the East and West.

Background: The Sasang constitutional analysis tool (SCAT) is an integrated Sasang constitutional analysis system developed by the Korea Institute of Oriental Medicine. This study aimed to evaluate the reliability of a questionnaire for measuring personality and pathophysiological symptoms that is one of the components of the SCAT. Methods: In this study, data were collected from university students in their twenties. Tests were administered twice, with an interval of 4 weeks between tests. Test-retest data from 176 students were collected and used for analysis. Internal consistency reliability was analyzed by using Cronbach's alpha coefficient, and test-retest reliability was analyzed by using Spearman's rank correlation coefficient. Results: Cronbach's alpha coefficient was 0.788 for personality, 0.511 for eating habits, 0.718 for digestion, 0.667 for heat- or cold-wise penchant, and 0.612 for water ingestion. Spearman's rank correlation coefficients, which were used to assess correlations between test and retest results, ranged from 0.444 to 0.828. Conclusion: The internal consistency and test-retest reliability of the SCAT questionnaire were found to be satisfactory.

Objectives The Yin-Yang construct was shown to have stable internal reliability or consistency using Sasang Personality Questionnaire (SPQ) throughout the various ages, however the study of stability over specific period of time was only conducted using adults. The purpose of the study was to examine the stability across the time using middle school students whose physical and psychological characteristics were most rapidly changing. Methods The 122 middle school students (65 boys and 57 girls) completed the SPQ at 1st year and 2nd year with one-year time difference. Cronbach's ${\alpha}$ and Pearson's correlation analysis were employed in order to show the internal consistency and stability over one-year interval after considering sex difference. Results The internal consistency of SPQ-T, SPQ-B, SPQ-C, SPQ-E using Cronbach's ${\alpha}$ were .61, .72, .28, .28 in 2016 and .62, .72, .26, .46 in 2017. The one-year test-retest reliability of SPQ-T, SPQ-B, SPQ-C, SPQ-E using Pearson's correlation analysis were .56, .61, .31, .23 in boys and .58, .63, .64, .29 in girls. Conclusion The current study showed the stability of Yin-Yang temperament across the one-year time suggesting that the Yin-Yang temperament is quite stable and measurable concept and the SPQ would be considered as an objective and reliable personality assessment.

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.

Objectives: In order to investigate personality of oriental medical students by MMPI elementarily. Methods: This study was done by comparing the score of MMPI and Sasang questionnaire. The scores of MMPI and Sasang were verified by examination of T-test and Tukey's HSD Procedure. Results: 1. According to comparison between male and female, there is no meaning. But between unmarried group and married group, there is a difference of MMPI T-scores for L, K-scale significantly. 2. In the distinction of sex and marriage between A group and B group, the MMPI T-scores of male and unmarried group have more significance on the various scale. 3. According to comparative anaylsis of MMPI and Sasang questionnaire, Um group(Tae-um, So-um group) showed significant results in D(Depression), PT(Psychasthenia), SI(Social Introversion) scales of the MMPI. 4. In comparison between the temperament of Sasang and analysis of MMPI profile, Tae-um and So-um groups showed many similarities. Conclusion: According to the above results, it is considered that MMPI can be applied to classification of constitution.
