The purpose of this study was to validate the Korean version of autonomy preference index (K-API) for chronic patients. Participants were 569 chronic patients. Construct validity and reliability of K-API were examined using exploratory and confirmatory factor analysis, and Cronbach's α test. Original API was translated to Korean, and we conducted contents validity test, and pilot test. The K-API consisted of 10 items divided into two domains: (i) Decision making preference (DMP); (ii) Information seeking preference (ISP). K-API explained 53.4% of autonomy preference; the two-factor structure showed an acceptance fit. Cronbach's α was. 77 for DMP, and. 75 for ISP. Validity and reliability of the K-API were established, and this study provides additional evidence for the usage of the API in Asian region.

Objective : This study aimed to create a Korea translation of the Evaluation in Ayres Sensory Integration (EASI) and to then test the adapted version for construct validity. Methods : The translation and content validation process were conducted in accordance with a four-step process, namely translation, integration, content validity examination, and backward translation. The construct validity of the translated version was evaluated using the EASI for children aged 3~12 years with and without sensory integration problems, comparing the two groups as well as preschool and school-aged groups. The group comparison was analyzed using the Mann-Whitney U test in SPSS. Results : In terms of content validity, all 20 items averaged more than 3.17 points. Of the four EASI categories, there was a difference in Sensory Perception (p=0.044) between the typical and sensory integration groups, and there was a statistical difference between tactile and vestibular sensations. Between the preschool and school-aged children, statistical difference was observed in two categories, namely Praxis and Ocular-Postural-Bilateral Motor Integration. Conclusion : Based on its construct validity, the Korean version of EASI is suitable for use in research. The construct validity study highlighted items that explain differences between typical and diagnostic children and items that explain those differences by age. Our findings could therefore be considered when interpreting EASI results.

This was a methodological study that verified the validity and reliability by translating and modifying the Korean Version of LRM (leader rapport management) tool. This study verified the content validity, construct validity, concurrent validity and convergent validity on 200 nurses working in general hospitals. The LRM tool was analyzed using a total of 3 factors (ego, autonomy, association) and 12 items. The reliability of this tool (Cronbach's ${\alpha}$) was 0.83 to 0.86. The tool showed a high level of reliability and validity. The difference from preceding studies showed that the LRM is a measurement tool that considers multi-dimensional aspects, and it can provide the basic material of report management methods in diverse aspects for clinical nurse managers.

This study aims to evaluate psychometric properties of the korean version of the secondary traumatic stress scale. A total of 238 practitioners in child protection agencies are recruited using complete enumeration method. The psychometric properties of the instrument are tested by item-analysis, exploratory factor analysis,(EFA) and convergent and construct validity. The results show that the internal consistency values for the two dimensions of the K-STSS are good. While the convergent and discriminant validity is empirically confirmed, the construct validity is not supported. The EFA with the common factor analysis method reveals the factor structure in the observed variables. The findings of the study confirmed that although it was reliable and discriminant, the K-STSS needed to be explored more in a way to support construct validity.

The purpose of this study were to factor analyze the 25-item Personal Resource Question-naire (PRQ)-Part II, a social support measure, and to establish construct validity for the instrument among adolescents by relationship found between perceived social support and the theoretically relevant variables of attachment, parent-child relationships, and coping, The sample was consisted of 451 college students, aged 18 to 24. According to the criteria used in this study a four-factor structure, which consisted of 15-items, resulting from a principal components analysis with an oblique rotation, best represented the multidimensionality of the PRQ-Part II of late adolescents in Korea. Evidence in support of construct validity for both the 15-item and 25-item PRQPart II was provided by statistically significant correlations found between the two scales and the theoretically relevant variable of attachment, parent-child relationships, and coping. With the findings of this study, the 15-item Korean version of the PRQ-Part II can be used in research and practice as a reliable and valid instrument measuring perceived social support for late adolescents in Korea.

Approximate number sense(hereafter, ANS) is the ability to compare and operate upon numerosity information. The numerosity comparison task is used to measure ANS. However, there is considerable variance among previous reports of ANS acuity which may be related to different task formats used. Here, we aim to investigate whether the format of the numerosity comparison task influences measurements of ANS acuity. We compared two task formats; 1) an intermixed format presenting two intermixed arrays of black and white dots, and 2) a side-by-side format showing two arrays of dots side by side. The intermixed format likely makes additional demands on general cognitive resources for inhibitory control, selective attention, or visuospatial working memory. The performance on the intermixed format was significantly lower than that of the side-by-side format resulting in an underestimation of ANS acuity compared to the expected trajectory of ANS development. In addition, the ANS acuity measured from only the side-by-side format was correlated with children's mathematical achievement and age. Our results demonstrate that measurement of ANS from the side-by-side format has higher construct and predictive validity compared to that of the intermixed format.

The purpose of this study is to develop and validate the Korean Job Crafting Scale. First, previous studies on the concept and measurement of job crafting were reviewed, and items were developed based on this review. The content validity of the scale was examined using a focus group interview consisting of 10 HRM professionals. Following modification of the items, the measurements were administered to 305 employees from 8 Korean firms, and exploratory factor analysis was conducted in order to examine the factorial validity of the scale. Subsequently, confirmatory factor analysis was implemented concerning data collected from 295 employees who work in 7 Korean firms. Results indicated that the measurement model sufficiently explained the data at an appropriate level, and the subscales featured convergent and discriminant validity. If the scale developed in this study is validated in further studies, it can be employed to conduct research regarding job crafting in Korean organizations.
