1. Objectives This study focuses on the Validity of the Questionnaire about Sasang Constitution Classification for Mongolians 2. Methods By using the way of backward elimination, certain variables are chosen from the 438 cases whose physical conditions are absolutely diagnosed. After that, discriminant analysis for the selected variables has been done to obtain the physical constitution equation and the accuracy ratio of diagnosis which are useful for physical constitution diagnosis. 3. Results and Conclusions (1) In tile Validity for the Questionnaire of Sasang Constitution Classification for Mongolians, the accuracy ratio of diagnosis of Taeyangin is 100%, Soyangin 62.5%, Taeumin 76.7%, and Soeumin 66.1% respectively as a result of the discriminant analysis employing Cronbach's alpha coefficient. On the whole, the accuracy ratio of diagnosis is 70.1%. (2). In the Validity for the Questionnaire of Sasang Constitution Classification for Mongolians, the accuracy ratio of diagnosis of 70.1% means that it beats the maximum chance criterion of 41.4% and the proportional chance criterion of 34.4% by 28.7% and 35.7% respectively. Conclusively, this questionnaire has discriminant power.

Replication of the factor structure of the TBAQ(Toddler Behavior Assessment Questionnaire Goldsmith, 1988) in Korean 2-year-old children was examined by Multitrait Multimethod matrix of observed and reported child behavior. Participants included 113 toddlers and their mothers. Three factors comprising 63 items were identified and labeled as easy, difficult and fearful. On the Child Behavior Checklist(Achenbach & Edelbrock, 1983) difficult temperament was positively related to externalizing while fearful temperament was positively related to internalizing problems. Observation of inhibited child behavior in both unfamiliar social and nonsocial situations demonstrated a positive relationship to observed inhibition of fearful temperament. Easy temperament correlated negatively with both social inhibition and internal behavior problems. Results supported construct validity of TBAQ factors for Korean 2-year-old children.

We are developing the methods for the objective and systematic diagnosis, but in actuality the relativity between a diagnosis of Korean medical doctor to a symptom of patients and the conformity to the expression of the Korean medical diagnostic mechanism is short of the statistical data. so, the questionnaire of Cold-Heat & Deficiency-Excess and a diagnosis of Korean medical doctor and a result of the Korean medical diagnostic mechanism, through the relationship of those, we have offered the objective data for diagnostic validity. The study group was 750 volunteers who diagnosed by Cold-Heat & Deficiency-Excess, out of 1475 volunteers who participated in Korean-Western medical examination. We compared the results of the questionnaires for Cold-Heat & Deficiency-Excess patternization through the questionnaire with a diagnosis of Korean medical doctor. we also studied the diagnostic validity for the item of the questionnaire by statistics analysis. It is proper that 9 questions of 16 questions for the Cold, 6 questions of 14 questions for the Heat, 13 questions of 14 questions for the Deficiency, 6 questions of 9 questions for the Excess, and there is close correlation between the questionnaire to the diagnosis. The difference between the questionnaire score is meaningful(p=0.000), this conforms to the diagnosis of the Korean medical doctor, so the questionnaire have the validity. The result of the questionnaire of Cold-Heat & Deficiency-Excess conform to a diagnosis of Korean medical doctor, it carries an important meaning by the measure of diagnosis, and it is necessary for further study for the significance of the medical diagnostic mechanism.

Background: Pectus excavatum (PE) is the most common chest wall deformity. The Nuss Questionnaire modified for Adults (NQmA) is a disease-specific health-related quality of life assessment tool for patients with pectus deformities. The aim of this study is to adapt the NQmA into Turkish. Methods: Two hundred and sixty-five patients with PE were participated, with an age range of 14 to 29 years. All patients underwent a physical examination and had not undergone corrective surgery. The Turkish version of the NQmA was completed by patients and their parents. Results: The content validity index based on expert opinions was 91% for the patient questionnaire and 96% for the parent questionnaire. The Cronbach's alpha value for the NQmA was found to be 0.805 for the patient questionnaire and 0.800 for the parent questionnaire. Exploratory factor analysis was used to assess construct validity. Two factors explained 51.1% of the total variance in the patient questionnaire (psychosocial: 31.145%, Cronbach's alpha=0.818; physical: 19.955%, Cronbach's alpha=0.862). In the parent questionnaire, two factors explained 51.422% of the total variance (psychosocial: 26.097%, Cronbach's alpha=0.743; physical: 25.325%, Cronbach's alpha=0.827). Construct validity was confirmed by confirmatory factor analysis. Conclusion: The Turkish version of the NQmA was found to be valid and reliable for the assessment of quality of life in patients with PE.

This study presents the psychometric properties of the Infant Behavior Questionnaire-Revised (IBQ-R), including internal consistency, content validity, and construct validity. The IBQ-R is a caregiver (parent) reporting instrument designed to assess temperament in infants (aged 3-12 months). Two groups of participants were included. The first group comprised 92 infants and the second 83 infants, giving a total of 175 infants (M=8.3 months, 80 boys and 95 girls). Their caregivers completed IBQ-R. The IBQ-R subscales demonstrated adequate internal consistency. Also, confirmatory factor analyses of the IBQ-R scale found that three broad dimensions: surgency, negative affectivity, and orientation/regulation. This study confirmed that the IBQ-R is a reliable and valid temperament instrument that can be recommended for evaluating temperament in infants.

Purpose: The purpose of this study was to develop and test psychometric properties the Korean version of the End-Stage Renal Disease Adherence Questionnaire (KESRD-AQ). The ESRD-AQ, a 46-item, multidimensional, self-administrated questionnaire which was developed to assess treatment adherence to hemodialysis (HD) attendance, medications, fluid restrictions, and diet prescription among patients on maintenance hemodialysis, has been validated. Methods: The KESRD-AQ was developed by performing both translation and backtranslation. The content validity and test- retest reliability of the KESRD-AQ were evaluated by establishing item-level content validity index (I-CVI) and intra-class correlation coefficients (ICC), respectively. Construct validity was assessed by adopting a known-group analysis comparing adheres and non-adherers using Mann-Whitney U Test. Results: 41 Korean-American patients with ESRD on HD from 3 outpatient dialysis centers in California participated in the study. The KESRD-AQ showed excellent content validity (average I-CVI=.96) and test-retest reliability (ICC=.917, p=.004). The construct validity indicated that the KESRD-AQ distinguished adheres and non-adheres (p=.02~.047). Conclusion: The KESRD-AQ is a valid and reliable instrument to measure treatment adherence.

Objectives: Several pattern diagnosis questionnaires have been developed to objectify the process of pattern diagnosis in Korean medicine. In this context, this study aimed to develop a food retention questionnaire for functional dyspepsia (FRQ-FD) by modifying the previously developed food retention questionnaire (FRQ) and to verify its reliability and validity. Furthermore, this study aimed to identify the optimal cut-off value of the FRQ-FD for standardization and use in clinical situations. Methods: To develop the FRQ-FD, we extracted the major symptoms of food retention pattern for functional dyspepsia from Chinese/Korean medicine textbooks and requested an importance survey from experts using the Delphi method. The first draft of the FRQ-FD was composed of 25 questions comprising 8 questions from the textbooks and the Delphi method and 17 questions from the FRQ already developed in 2013. To analyze its reliability, validity, and optimal cut-off value, 60 subjects were enrolled in this study from June 25 to August 13, 2018. Thirty patients were diagnosed as both functional dyspepsia and food retention pattern, and 30 healthy participants were not. All participants were requested to fill up the FRQ-FD, Stomach Qi Deficiency Questionnaire (SQDQ), Scale for Stomach Qi Deficiency pattern (SSQD), visual analog scale (VAS) for dyspepsia, Nepean Dyspepsia Index-Korean version (NDI-K), and functional dyspepsia-related quality of life (FD-QoL). Results: No statistically significant differences were found in sex distribution, age, and body mass index between the patient group and the control group. As five questions affected the reliability negatively and three questions affected the clinical validity negatively, we decided to exclude the eight questions upon further investigation. The Cronbach's ${\alpha}$ coefficient of the revised FRQ-FD (17 items) was 0.899, and its clinical validity was verified. Construct validity was analyzed by factor analysis and produced five factors. Statistically significant positive correlations were found between the revised FRQ-FD and the other dyspepsia scales, namely, SQDQ, SSQD, VAS, NDI-K, and FD-QoL. VAS and NDI-K especially had strong positive correlations with FRQ-FD. Conclusions: The FRQ-FD developed in this study can provide fundamental reliability and validity for a pattern diagnosis questionnaire. FRQ-FD can help to diagnose food retention pattern in functional dyspepsia patients. Further studies are required to inspect several statistical factors.
