  • 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.

  • Technology adoption for information appliance, which is expected to grow rapidly in the near future, is different from other technologies in that it is mainly used in the home environment when the customers haven't experienced it before. This paper finds important variables from prior research about technology adoption and develops a measurement model that fits for the information appliance. Pretest and pilot studies for the model is conducted in order to guarantee content validity, reliability, convergent validity and discriminant validity. Finally, LISREL analysis is used for finding out the causality among variables and testing for model fitness. The results indicate that three factors that influence behavioral intention are attitude, subjective norm and perceived behavioral control. Attitude is influenced by attitudinal belief, which consists of perceived usefulness, trialability, result demonstrability, image and enjoyment. Perceived behavioral control is influenced by control belief that consists of rapid change in technology, cost and ease of use. This paper ends with implications and limitations of study results.

  • Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of nurses' attitudes toward delegation and preparedness to delegate (APD). Methods: The Korean version of APD was developed through forward-backward translation methods. Internal consistency reliability, criterion validity, and construct validity using exploratory and confirmatory factor analysis were conducted using IBM SPSS Statistics 19 and AMOS 20.0. Survey data were collected from 161 nurses working in 2 general hospitals. Results: The Korean version of APD showed Cronbach's alphas of .68 and .85. Factor loadings of the 8 attitude items on the 3 subscales ranged from .60 to .86 and the 15 preparedness items on the 4 subscales ranged from .47 to .90. The model of 3 subscales for the Korean nurses' attitude toward delegation and the model of 4 subscales for the Korean nurses' preparedness to delegate were both validated by confirmatory factor analysis(NC<3, CFI>.90, RMSEA<.10). Criterion validity compared to job satisfaction showed significant correlation. Conclusion: The findings of this study demonstrate that this modified Korean version of APD is applicable for measuring Korean nurses' attitude toward delegation and preparedness to delegate.

  • Korea DM&S(Defence Modeling & Simulation) development plan includes construction of a distributed simulation model which enables us to construct, operate, integrate and connect war game simulations. US DoD and IEEE set the HLA/RTI as the standard of distributed simulation model. HLA/RTI models each simulator as a Federate and group of them as a Federation. Simulation with the model shows interoperability and finally executes a war game simulation. Because of different resolutions and features, it is not satisfied 'interoperability' and 'reusability' of simulation perfectly MRM (Multi Resolution Modeling) has been introduced, and many developed countries including the United States have studied the technology to simulate the model with different resolutions. This thesis proposes the need for introduction of MRM and analyzes both technical and operational validity when we apply MRM model to army war game simulations. For these purposes, we 1) find MRM main issues with the study about MRM basic concepts and case studies of MRM's applications, 2) present the need of MRM and its relation with DM&S development plan, and 3) analyze its technical and operational validity when we apply MRM to an example, CHANG-JO21 and JEON-TOO21.

  • The purpose of this study is to construct validity of Tripartite model of "Attitudes towards Science" using Exploratory and Confirmatory Factor Analyses. Exploratory and confirmatory factor analyses are two major approaches to factor analysis. The primary goal of factor analysis is to explain the covariances or correlations between many observed variables by means of relatively few underlying latent variables. In exploratory factor analysis, the number of latent variables is not determined before the analysis, all latent variables typically influence all observed variables, the measurement errors(${\delta}$) are not allowed to correlate, and unidentification of parameters is common. Confirmatory factor analysis requires a detailed and identified initial model. Confirmatory factor analysis techniques allow relations between latent and observed variables that are not possible with traditional, exploratory factor analysis techniques. As a result of exploratory factor analysis, tripartite model of "Attitudes towards Science" being composed of affection, behavioral intention and cognition is empirically identified. But attitude of science career being composed of affection and behavioral intention is identified. In validity test using confirmatory factor analysis, measurement structure of Tripartite model of "Attitudes towards Science" is not correspondent to data set. Because it is concluded that the object of attitudes are not specific.

  • Purpose: The study was done to identify the construct validity and reliability of the life transition scale (LTS) for parents who have children with autism. Methods: Exploratory factor analysis (EFA) and confirmative factor analysis (CFA) were conducted to identify the most adequate measurement model for structural validity. Convergent validity and discriminant validity were also conducted for structural validity. Data were collected from 208 parents through self-reported questionnaires and analyzed with SPSS/WIN 15.0 and AMOS 20.0 version. Results: A four factor-structure was validated (${\chi}^2$=541.23, p<.001, GFI=.82, RMSEA=.07, IFI=.89, CFI=.89, PNFI=.73, Q (${\chi}^2/df$)=2.20) at the 3rd order of EFA and CFA, and factors were named as denying, wandering, despairing, and accepting. Both convergent and determinant validity for LTS were 100%. Cronbach's alphas for the reliability of each structure were .77-.90 and .83 for total structure. Conclusion: The four structures, 24-item instrument showed satisfactory reliability and validity. LTS has the potential to be appropriate for assessing the transition process of life for parents who have children with autism and provides basic directions for differentiated support and care at each stage.

  • Background: Colorectal cancer is a serious health problem. Early detection of colorectal cancer is crucial for treatment and reducing mortality. Beliefs related to colorectal cancer have been found to be a factor in a person's decision about colorectal cancer screening programs. To determine such beliefs, a valid and reliable instrument is necessary. Objective:The aim of this study was to adapt and determine the psychometric properties of the Persian version of Champion's Health Belief Model Scale of breast cancer screening in the measurement of beliefs toward colorectal cancer (CRC) screening. Materials and Methods: The 'forward-backward' procedure was applied to translate the instrument from English into Persian. This study was conducted in Iran from June 2012 to May 2013. A convenience sample of 200 individuals aged 50 years and older was recruited from the population at the outpatient clinics in the three teaching hospitals. Validity was assessed using content, face and construct validity. To test reliability, the internal consistency was assessed by using Cronbach's alpha coefficient and test-retest (intraclass correlation coefficient) analyses. Exploratory factor analysis was used to assess the construct validity and determine the factors of adapted Champion's Health Belief Model Scale. Results: The mean age of the participants were 62.5 years (SD=10.8 years) and the majority of them (75.5 percent) were female. The results of exploratory factor analysis indicated a six-factor solution for the questionnaire (benefits, motivation and confidence, seriousness, susceptibility, emotional barriers and background barriers) that jointly accounted for 55.52% of variance observed. Cronbach's alpha of the subscales ranged from 0.57 to 0.89 and test-retest reliability ranged from 0.81 to 0.93 indicating a good range of reliability. Conclusions: The findings of this study suggest that the Persian version of Champion's Health Belief Model Scale of CRC screening has good psychometric properties and could be an appropriate measure for health beliefs related to CRC screening in national and international studies.
