  • Mathematics Teaching Efficacy Beliefs Inventory (MTEBI) was translated into Korean and conducted among Korean pre-service mathematics teachers. The Korean-translated MTEBI consists of two subscales with 16 items. Personal Mathematics Teaching Efficacy (PMTE) subscale has 10 items and Mathematics Teaching Outcome Expectancy (MTOE) subscale has 6 items. The purpose of this study is to investigate the internal reliability and the construct validity of the Korean-translated MTEBI. The Cronbach alpha coefficient of Korean-translated MTEBI and its two subscales are respectively .87, .83, and .74 which imply that the instrument is reliable. The construct validity was achieved by performing factor analysis. Principal component solution with varimax rotation for the Korean-translated MTEBI was used in factor analysis and thus the best fit simple structure was obtained by two factors which correspond to the self-efficacy dimension and the outcome expectancy dimension of Bandura's self-efficacy theory.

  • This study verified the reliability and validity of the Korean version of the Student Career Construct Inventory(K-SCCI) that was translated into Korean language from the Student Career Construct Inventory (SCCI) developed by Savickas et al.(2018). To achieve this, this study conducted item content analysis, exploratory factor analysis, confirmatory factor analysis, and criterion-related validity in 530 university students. As a result of item content analysis and exploratory factor analysis, it was found that 4 factor models and 18 items were the most appropriate in K-SCCI. The 4 factors were named as crystallizing a vocational self-concept, exploring to gather information about occupations, deciding to commit to an occupational choic, and preparing to implement that choice. As a result of confirmatory factor analysis to verify the goodness-of-fit of the 4 factor models, it appeared to be appropriate. As a result of analyzing the correlation with related measures to verify the criterion-related validity of measures, it was found that student career construct was negatively correlated with employment anxiety but positively correlated with career adaptability.

  • The purpose of this study was to verify the construct validity of self-evaluated writing scale for students with disabilities who had difficulties in writing. After interpreting the Here's How I Write scale developed by Goldstand et al. (2013), we administered Delphi survey to 40 special education professionals, calculated the content validity ratio and decided the final scale of 21 questions applicable to Korea. Additionally, we carried out the scale to 350 disabled and normal students for testing construct validity. The main results are as follows: For both students with disabilities and without disabilities, the overall internal consistency of scale are higher than .89 and the internal consistency of factors of scale are higher than .66. The confirmative factor analysis using AMOS 21.0 and SPSS 21.0 to verify construct validity showed fit index at relatively satisfactory level for students with disabilities and without disabilities. Furthermore, while there were relatively strong convergent validity and discriminant validity in the sub-factors of scale for students without disabilities, the level of convergent validity and discriminant validity were relatively lower for students with disabilities.

  • Background Carpal tunnel release is one of the most common surgical procedures performed by hand surgeons. The authors created a surgical simulation of open carpal tunnel release utilizing a mobile and rehearsal platform app. This study was performed in order to validate the simulator as an effective training platform for carpal tunnel release. Methods The simulator was evaluated using a number of metrics: construct validity (the ability to identify variability in skill levels), face validity (the perceived ability of the simulator to teach the intended material), content validity (that the simulator was an accurate representation of the intended operation), and acceptability validity (willingness of the desired user group to adopt this method of training). Novices and experts were recruited. Each group was tested, and all participants were assigned an objective score, which served as construct validation. A Likert-scale questionnaire was administered to gauge face, content, and acceptability validity. Results Twenty novices and 10 experts were recruited for this study. The objective performance scores from the expert group were significantly higher than those of the novice group, with surgeons scoring a median of 74% and medical students scoring a median of 45%. The questionnaire responses indicated face, content, and acceptability validation. Conclusions This mobile-based surgical simulation platform provides step-by-step instruction for a variety of surgical procedures. The findings of this study help to demonstrate its utility as a learning tool, as we confirmed construct, face, content, and acceptability validity for carpal tunnel release. This easy-to-use educational tool may help bring surgical education to a new- and highly mobile-level.

  • Purpose: The aim of this study was to test the validity and reliability of the Korean version of the Quality of Nursing Work Life (QNWL-K) scale. The scale measures the reported quality of the nurse' work life among Korean nurses. Methods: The QNWL-K was developed through forward-backward translation techniques. An internal consistency reliability and construct validity using exploratory analysis were conducted using SPSS/WIN (21.0). Survey data were collected from 309 nurses who worked in two tertiary hospitals, four general hospitals, and two hospitals in Seoul and Gyeonggi, South Korea. Results: Factor analysis results of the revised QWNL-K demonstrated that it has a four-factor structure (work context, support systems for home/work life, work design, and staffing) that supports construct validity. Factor loadings of the 36 items ranged from .30~.77. The QNWL-K showed reliable internal consistency from Cronbach's ${\alpha}$ for the total scale of .93. Conclusion: The findings support that the QNWL-K has satisfactory construct validity and is a reliable measure of nursing work life in Korea.

  • 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.

  • Purpose: To develop and test the validity and reliability of the Korean version of the Family Management Measure (Korean FaMM) to assess applicability for families with children having chronic illnesses. Methods: The Korean FaMM was articulated through forward-backward translation methods. Internal consistency reliability, construct and criterion validity were calculated using PASW WIN (19.0) and AMOS (20.0). Survey data were collected from 341 mothers of children suffering from chronic disease enrolled in a university hospital in Seoul, South Korea. Results: The Korean version of FaMM showed reliable internal consistency with Cronbach's alpha for the total scale of .69-.91. Factor loadings of the 53 items on the six sub-scales ranged from 0.28-0.84. The model of six subscales for the Korean FaMM was validated by expiratory and confirmatory factor analysis (${\chi}^2$ <.001, RMR<.05, GFI, AGFI, NFI, NNFI>.08). Criterion validity compared to the Parental Stress Index (PSI) showed significant correlation. Conclusion: The findings of this study demonstrate that the Korean FaMM showed satisfactory construct and criterion validity and reliability. It is useful to measure Korean family's management style with their children who have a chronic illness.

  • The objective of this study was to develop and evaluate the construct validity of a Nutrition Quotient (NQ) for children. In a previous report (Kang, et al., 2012), the food behavior checklist for children's NQ, consisting of 19 items, was grouped into a 5-factor structure according to the exploratory factor analysis: balance, diversity, moderation, regularity, and practice. In this study, the construct validity of the NQ was assessed using a confirmatory factor analysis. Elementary school students (n = 1,393) from six large cities completed the NQ test. Indicator tests suggested an adequate model fit (goodness of fit index = 0.9613; adjusted GFI = 0.95; standardized root mean square residual = 0.0464; chi-square test statistics of < 0.001 p-value, 82.1), and item loadings were significant for all subscales (p < 0.05). The standardized path coefficients were used as the weights of the items. The NQ and the 5 factor scores of the student were calculated by the obtained weights of the questionnaire items. Logistic regression was applied to find the significant factors in order to affect a specific nutrient status. The receiver operation characteristic curve analyses were performed in order to find diagnostic cut-off points of the five factors. The food behavior checklist for children's NQ would be a handy and suitable instrument for evaluating dietary behaviors of Korean children.

  • Objective : This study aimed to verify the construct validity of the Korean version of the Peabody Developmental Motor Scale-2 (K-PDMS-2) and its test-retest reliability for children with cerebral palsy (CP) and typical children. Method : To ascertain the construct validity, the K-PDMS-2 evaluation was conducted on 42 children with cerebral palsy and 42 typical children of similar age and gender. Construct validity was proved through comparison with standard scores. Ten of the children with CP were re-evaluated after two weeks to determine test-retest reliability. Results : There was a statistically significant difference in gross motor and fine motor development according to five subtests between the group of children with CP and the typical group (p = .000). For test-retest reliability, the correlation coefficient of the total frequency score was .989, representing very high temporal stability. Conclusion : This study confirmed that K-PDMS-2 is an evaluation tool of high reliability and validity, and a potentially useful future measure for domestic clinical sites and research.
