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: Eating self-efficacy is an important predictor of successful weight control behaviors during obesity treatment. The Weight Efficacy Life-Style Questionnaire (WEL) is an internationally used measure of eating self-efficacy. The objective of this study was to develop the Korean version of WEL (K-WEL) and verify face validity. Methods: According to previously published guidelines, the cross-cultural translation was conducted through organizing the expert committee, translation, back-translation, synthesis, grammar review, and final synthesis. Following the translation of the WEL into Korean, face validity was performed for 35 subjects. Results: After all the versions of the questionnaire were examined, the translated WEL questionnaires were finally synthesized and licensed by the developer in writing. Regarding the translated WEL questionnaires, seven out of 35 subjects (20%) offered ideas about ambiguous expressions in them. All four points indicated in the face validity verification were additionally modified for greater clarity and understanding. Conclusions: We developed the Korean version of WEL and completed face validity. In future research, it would be necessary to provide further study on the reliability and validity of the Korean version of WEL.

The purpose of this study was to examine the psychometric property of the Children's Behavior Questionnaire(CBQ), including reliability, content validity, construct validity, cross validity, and concurrent validity with EAS(Emotionality, Activity, Sociability) scale. The CBQ is a caregiver report measure designed to provide a detailed assessment of temperament in children 3 to 7 years of age. In this study, two groups of participants were included to check cross validity. The first group of participants were 108 preschoolers, 3 to 7 years of age attending kindergartens or child care centers, and their mothers. The second group of participants were 168 preschoolers and their mothers. The CBQ subscales demonstrate adequate internal consistencies. Also, exploratory and confirmatory factor analyses of the CBQ scale reliably recover a three-factor solution indicating three broad dimension of temperament: extraversion/surgency, negative affectivity, and effortful control. Evidence for concurrent validity derives from results of correlation analysis with EAS scale.

The measurement of informatization program effectiveness continues to be a central concern of both academics and practitioners. However, most studies of it have been inclined too heavily toward testing validity and reliability of evaluation measure to strengthen the theoretical rigor. Drawbacks of this approach have been pointed out as being unsuitable for evaluating the effectiveness of informatization program due to lack of practical relevance. The paper comprises four sections to solve the problem. 1) Through literature review of theoretical conceptual models in IS effectiveness and the domestic and foreign cases on informatization program, we establish the evaluation framework which consists of evaluation phases, 6 evaluation areas, and 22 evaluation items, and developed evaluation measures of each items. 2) Different researchers have addressed different aspects of attribute of measure. With comparing them to each other, 3 mutually exclusive criteria on coincidence analysis(usability of measurement. reliability of measurement. and validity of content) are identified. 3) Data are gathered from respondents in informatizaiton program-related organizations such as policy agency, management agency, support agency, and recipient agency. 4) The degree of coincidence of each evaluation measure are analyzed by course of an coincidence analysis procedure, which includes the reliability test, arithmetical test, and criteria validity test. The academic implication of this study is that researchers can gain an insight into the coincidence analysis to approach the problem of deciding on an indicator of performance for informatization program. There is also practical implication for applying the potential means of improving the practical relevance of conducting evaluating the informatization program.

Concern for patient safety underlies the need for interprofessional education (IPE). One way to measure the effectiveness of IPE is by measuring attitude change toward other healthcare professionals; however, there are currently no valid Korean tools to measure such a change in attitudes. Therefore, this study aims to develop and test a Korean version of the Interprofessional Attitudes Scale (IPAS). The original IPAS was translated into Korean according to the World Health Organization's guidelines after obtaining permission from the article's corresponding author. A total of 414 questionnaires were collected from third- and fourth-year medical and nursing students at four Korean institutions in December 2018. To analyze the validity of the Korean IPAS, exploratory and confirmatory factor analyses were conducted. Cronbach's α was used to evaluate reliability. Results from the exploratory factor analysis identified four functions: teamwork, community-centeredness, patient-centeredness, and respect for diversity. Significant cross-correlations were found among the four functions (r=0.438-0.631, p<0.001) along with overall reliability (Cronbach's α=0.929) and reliability of each subfactor (Cronbach's α=0.804-0.897). This study verified the validity and reliability of the Korean version of the IPAS, so this scale can be used in the future to measure the effectiveness of IPE in Korea.

The control effectiveness and disturbance suppressibility are mainly governed by a left eigenstructure of a system. In this paper, a control algorithm which uses an output feedback eigenstructure assignment scheme is proposed in order that a desired closed-loop system has the specified degree of controllability and/or degree of disturbance suppressibility. To do this, a modal and a gross disturbance suppressibility measures are proposed. A modified version of Hamdan and Nayfeh's modal controllability measure is also presented. The validity and usefulness of the proposed measures and the controller design algorithm are illustrated by designing a controller for a third-order system as an example.

This study investigated whether the schema modes have validity in Korean adults. We examined the validity and reliability of the Schema Mode Inventory (SMI) in a Korean adult sample (N = 768; Mean age = 22.29 years; range = 19-55 years; 69.3% Males). Psychometric properties, such as factor structure, internal reliability, as well as intercorrelations among subscales were assessed. Confirmatory factor analyses yield satisfying fits for a 61-item Korean Schema Mode Inventory. Thirteen Schema Mode Inventory scales were found to have adequate reliability of the original 14 schema factors. Furthermore, the SMI scales differentiated between depressed and non-depressed participants as theoretically predicted. These findings imply that the SMI is a sound instrument to measure the schema mode model in a Korean setting for assessment prior to schema therapy.

In this study, we explored the psychometric properties of the Korean version of the Safety Organization Scale (K-SOS). The SOS is based on the principles of a high-reliability organization and is an effective measure of the self-reported behaviors underlying the safety culture of an organization. We conducted a methodological study to examine the validity and reliability of the 9-item SOS translated into Korean. The data of 108 nurses working in three general hospitals with more than 100 beds located in D City were included. Content validity, construct validity, criterion validity, and reliability were evaluated. The results confirmed that the K-SOS is a unidimensional structure scale. Higher K-SOS scores exhibited a significant correlation with Hospital Survey On Patient Safety Culture, thus indicating the validity of the criterion. The internal consistency of the K-SOS was acceptable. Thus, the K-SOS is a reliable self-report scale for directly measuring the safety behaviors of an organization. The K-SOS can be used to improve patient safety in Korean hospital settings.

Background: Many people experience varying levels of discomfort when confronted with the prospect of dental treatment. Dental treatment can be a traumatic experience, especially for children and adolescents with dental anxiety. In this age group, dental fear causes a significant problem in dental management and has been related to severe dental caries and dental pain. The Dental Fear Survey (DFS) is the most widely used measure of dental fear. This study was undertaken to develop the Korean version of the DFS (K-DFS) and test its reliability and validity. Methods: The K-DFS, which uses projective techniques to measure children's and adolescents' dental fear, was developed. The DFS was translated into Korean and participants were selected via convenience sampling. Reliability and validity were tested using data from a sample of 813 middle school students in Gyeonggi Province, selected from the Self questionnaire survey. The K-DFS was administered twice to 102 adolescents aged 12-15 years. Results: The K-DFS had high internal consistency reliability (99.1%) but low test-retest reliability. Conclusions: The results indicate that the Korean versions of the DFS have good internal consistency reliabilities and test-retest validities. However, we need to further examine the test-retest reliability of the K-DFS and replicate the current study in different samples covering various age groups.

Purpose: The purpose of this study was to develop and validate a diabetes management self-efficacy scale for older adults (DMSES-O). Methods: A preliminary DMSES-O of 22 items was derived from a literature review and seven domains of self-management behaviors. Content validity was confirmed by experts in diabetes self-management education. To test the reliability and validity of the DMSES-O, data were collected from 150 older adults with type 2 diabetes. The data were analyzed using exploratory factor analysis, and Cronbach's ${\alpha}$ and Pearson's correlation coefficients were calculated. Results: From the exploratory factor analysis, 17 significant items in six subscales were derived. Factors derived were named "problem solving for hypoglycemia and self-monitoring blood glucose," "problem solving for hyperglycemia," "coping with psychological distress and taking medication," "reducing risks of diabetes complications," "appropriate exercise," and "healthy eating." The criterion-related validity of the DMSES-O was established by its correlation with the Summary of Diabetes Self-care Activities Questionnaire. Cronbach's ${\alpha}$, a measure of internal consistency, was .84 for the overall scale and ranged from .54 to .80 for the subscales. Conclusion: The DMSES-O is a reliable and valid instrument to measure selfefficacy for diabetes self-management among older adults.
