This study aimed to examine the reliability and validity of a diagnostic instrument to be used to measure the developmental level of very young children (aged birth through 36 months) and to screen young children at risk. The subjects of this study were 861 young children. Data were analyzed by item response distribution, item discrimination, reliability, and validity of the scale. Items reflected the developmental level of each age group. Overall internal consistency was relatively high (Cronbach's ${\alpha}=.90{\sim}.95$), and test-retest (after 2 weeks) reliability was high. Content validity was examined by a panel of experts in the related field. The construct validity as well as the concurrent validity of this instrument was also established.

The purpose of this study is to develop clothing shopping orientation[CSO] scale reflecting the conceptual structure of CSO. For this purpose, a questionnaire composed of comprehensive 85 CSO items was developed through 2-step preliminary tests. Data was collected from two samples. One sample(n=559) was for scale development and the other sample(n=235) was for cross validity test. Descriptive analysis, correlation analysis, exploratory factor analysis, regression analysis, ANOVA, and confirmatory factor analysis were used for data analysis. For each lower-dimension within the CSO conceptual structure model, 1-2 items were selected based on the quantitative and the qualitative standards. As a result, a CSO scale composed of 31 items was developed, and reliability, construct validity, cross validity, convergent validity, discriminant validity, and criterion validity of the scale were verified. This study has significance in offering the standardized scale to both the academic and the practical fields.

This article presents the development of a self-report measure of Korean Marital Satisfaction Scale. Based on 'Family Process Model'and interviews with 183 married couple, 3 domain structures with 74 items were identified, which included interactional process, emotional process, and intellectual process. It was administerd to 289 couples to test reliability and validity. Overall reliability coefficients were high for each of the individual domains($\alpha$=.62 to $\alpha$=.93). Face validity, content validity, content validity and concurrent validity respectively were demonstrated good. Additionally, divergent validity with scales of self-esteem and depression was observed. These results support the reliability and psychometric validity of the Korean Marital Satisfaction Scale in the assessment of key dimensions of marital process of Korean couples.

Before evaluating convergent, discriminant, and known-groups validity, it is suggested to design an instrument that reflects hypothetical relationships or differences with other comparator instruments or groups. For criterion validity, a gold-standard instrument measuring the same construct should be carefully selected.

Purpose: This study is to verify the validity and reliability of classified items and criteria of the patient classification system(PCS) based on Park's definition of nursing intensity. Methods: An expert group of 8 persons verified the content validity of the tools. The 1817 inpatients at a tertiary hospital in Seoul, Korea were classified into 4 groups according to two tools for verifying concurrent validity and interraters' reliability. These verifications were performed from September to October, 2004. Results: Nursing domains of the tools have been divided into 12 items: hygiene, nutrition, elimination, exercise & activity, education & counseling, emotional support, communication & consciousness, treatment & examination, medication, measurement & observation, coordination of multidisciplinary team, admission & discharge & transfer management. Content validity was verified by the content validity index(above 0.75 in all 12 areas). Interraters' reliability was no significant difference in the results of the patient classification between the two raters(A group 93.75%. B group 88.24%). Concurrent validity was also verified by the agreement of two tools(73.7%). Conclusion: These results showed that the reliability and validity of the PCS based on the nursing intensity were verified. These will use an data for nursing productivity in the future.

This thesis is to propose the method of evaluating the validity in stages on the design of a checklist based on the estimate theory of the validity on the design of a checklist and the method of evaluating the validity accordy to the purpose for usiug checklist and establish the standards of estimating the validity in stages on the checklist owing to the estimate theory with the journal, Journal of the Korean Society of Clothing and Textiles. We are emboding the statistical consulting server using the proposed estimate method of the validity and the followings we the questions to solve in future. First, there are many kinds of the statistical methods used in the fields of learing and applied technalogy. So we must establish the statistical standars required in each field and study and develope the special statistical checklists. Second, it is neded to systemize the estimate methods and standard on the validity by building the statistical consult DB, evaluate the researchers according to the degrees of statistical knowledge the validity of study design iud propose the delicate and generalized statistical methods appropriate to the ability of researchers.

The United Nations Convention on the International Sale of Goods(CISG) leaves a number of aspects concerning commercial sales untouched. In particular, it is not concerned with the validity of the contract or of any of its provisions or of any usage. And UNIDROIT don't deal with all-round validity in International Commercial Contract. Especially, UNIDROIT includes declaration of intention department. The UNIDROIT contains the chapter 3 on the "validity" in terms of the defects of consent such as mistake, fraud, and threat as well as "gross disparity". Notwithstanding these provisions, the Principles did not deal with invalidity arising from the lack of capacity or authority, or immorality or illegality. On the other hand, there are arguments that the corresponding provisions of the Principles of International Commercial Contracts(UNIDROIT Principles; PICC). Therefore, Validity in International Commercial Contract is delegate by Each Country Law. So Trade practicer should know full well about Each Country Law Position. People(human, corporation, company) of position Trade practice classify each country civil law relation to validity of commercial contract. This paper is to examine the Validity of UNIDROIT Principles. Also this paper analyses comparison on each country position relation to capacity of right, capacity to act, illegality of contract, declaration of intention. In conclusion, This paper expect that people of trade practice makes use of analysis knowledge.

This study aims to develop an index of food security in order to assess food security status in Korea and to evaluate reliability and validity of the index. The index of food security was developed based on the US Household Food Security Survey Module (US-HFSS). After the US-HFSS was translated and back-translated, it was evaluated and modified by a focus interview for experts. The developed Korean Household Food Security Survey Module (K-HFSS) was tested by cognitive interviews and a pretest for general community population to assess its application for Korean population. For the reliability and validity of K-HFSS, the survey was conducted with 300 adults aged 40 years or more living in a rural community and 212 infants and toddlers living in an urban community. The reliability was assessed by Cronbach' alpha and the validity was evaluated by content validity, construct validity, and criterion-related validity. The questionnaire items of K-HFSS were partly modified, accounting for Korean social and cultural backgrounds and adapted by general community population. The reliability was relatively high, showing Cronbach' alpha coefficients ranged from 0.80 (for adults) to 0.87 (for infants and toddlers). The content and construct validities were all acceptable. The result of criterion-related validity showed that food security status was significantly related to the household income level. In conclusion, the K-HFSS would be used as a reliable and valid instrument to assess food security status in parts of the Korean population.

The purposes of this study were to examine the reliability and validity of Korean translation of Pediatric Evaluation of Disability Inventory (PEDI-K) in school-aged children with cerebral palsy (CP). The PEDI-K, Functional Independence Measure for Children (WeeFIM) and Gross Motor Function Classification System (GMIFCS) were completed in 104 school-aged children with CP by therapists. The internal consistency of the PEDI-K was calculated by Cronbach's alpha (${\alpha}$) for assessing reliability. Concurrent validity was evaluated by correlation with the subsets of WeeFIM. Discriminant validity was assessed by comparing GMFCS levels with tests of the PEDI-K. The results showed that internal consistency was good (Cronbach's ${\alpha}$ ranged from .97~.98). Concurrent validity was demonstrated. The correlation with WeeFIM was high in the Functional Skills (self-care, r=.74~.94; mobility, r=.59~.91; social function, r=.65~.93) and in the Caregiver Assistance (self-care, r=.75~.94; mobility, r=.63~.90; social function, r=.78~.96). Discriminant validity was demonstrated on significant decreases in domain scores with increasing GMFCS levels. Reliability and validity have been demonstrated on the PEDI-K. This study extends usage of PEDI-K in clinical activities and research.
