Purpose: The purpose of this study was to develop a Cardiovascular Disease Resilience (CDR) scale to evaluate disease specific resilience for recovery. Methods: The study was conducted as follows: items generation, and test of validity and reliability. Items were developed via literature review, review of instruments, and data acquired from the interviews. In order to test validity and reliability, seven panels of experts reviewed the preliminary questionnaire and then data were collected from 550 cardiovascular disease patients. Factor analysis, Pearson correlation, ANOVA, and Cronbach's alpha were used to analyze the data. Results: In the preliminary stage, forty-four items were generated. A reduction to 40 items was accomplished through content validity analysis. Factor analysis extracted 7 factors with a total of 25 items. The CDR items were moderately correlated with the subscales of the CD-RISC (Connor-Davidson Resilience Scale) and the mean score of CDR was associated with quality of life measured with CD-QOL (Cardiovascular Disease Quality of Life). Cronbach's ${\alpha}$=.84. Conclusion: Content validity, construct validity, criterion validity, and reliability of the CDR were established. The CDR is a reliable and valid instrument which the resilience of cardiovascular disease specific recovery state can be evaluated.

Objectives: This study evaluated the perception on importance of interprofessional core competencies (PI-ICCP) scale. Methods: Data were collected from 353 college students of health. Content validity was tested using the content validity index for individual items(I-CVI) and for scale(S-CVI). Criterion validity was tested using the professional competencies scale developed by Choi. Reliability was evaluated using Cronbach's coefficient alpha. The goodness-of-fit of the construct validity was determined through exploratory and confirmatory factor analyses. Results: The I-CVI of each item was .8 or higher for all items, and the S-CVI was .98. The reliability of the PI-IPCC was Cronbach's α=.98. The goodness-of-fit indices of the model were χ2=1811.54(p<.001), the comparative fit index (CFI)=.91, and root mean square error of approximation (RMSEA)=.08, which satisfied the criteria. Conclusions: The construct and criterion-related validity of the perception for PI-ICCP scale were a good fit, so the instrument is appropriate for measuring perception on importance of interprofessional core competencies. Further research will be required using this instrument to investigate perception of interprofessional core competencies of health professionals.

Purpose: The aim of this study was to assess the Turkish adaptation of the COVID Stress Scale (CSS) on the basis of determining the stress caused by the coronavirus disease (COVID-19) pandemic, and to test its validity and reliability. Methods: The English CSS was translated into Turkish using forward and backward translation. Data were collected online from 360 participants. Construct validity was evaluated using confirmatory factor analysis, exploratory factor analysis, and content validity. Pearson product-moment correlation, Cronbach's alpha reliability coefficient, and test-retest methods were used to evaluate reliability. Results: The Turkish version of the CSS has 36 items consistent with the original scale and has five factors: COVID danger and contamination, socioeconomic consequences of COVID, COVID xenophobia, traumatic stress due to COVID, and compulsive checking for COVID. The construct validity of the Turkish version of the CSS was verified by the adjusted goodness of fit index > .85, and comparative fit index > .95. The content validity index of each item was 91%. The corrected item-total correlations of the scale ranged from .51 to .89. Internal consistency was reliable, with a Cronbach's α of .93. Conclusion: The Turkish version of the CSS is valid and reliable. It can be used as a measurement tool for the assessment of COVID-related stress.

Objective : This study aims to verify the content validity and inter-rater reliability of the Korean version of the Peabody Developmental Motor Scale 2 (PDMS-2) and to identify the concurrent validity by comparing it with the Korean version of the Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2). Methods : PDMS-2 was translated by the researcher and an eighth-year clinical occupational therapist. The content consistency of the Korean version of the PDMS-2 was verified by three professors with experience using it. After the verification of the content consistency of the PDMS-2 by the five clinical occupational therapists and the additional revision, the Korean version of the PDMS-2 was completed. The researcher and another occupational therapist evaluated the Korean version of PDMS-2 in 50 children and measured the inter-rater reliability. Concurrent validity was measured by comparing the results of the Korean version of PDMS-2 and Korean version of BOT-2. Results : The content consistency test showed overall agreement of mean 3.45, and the content understanding test showed a high level of understanding of mean 3.69. The inter-rater reliability and concurrent validity of the Korean version of the PDMS-2 showed a statistically significant correlation. Conclusion : The Korean version of the PDMS-2 showed high content understanding, reliability, and validity. It can assist clinicians and researchers who work in fields related to child treatment or development.

Objective : This study was conducted to validate the content validity of the Korean version of the school setting interview (SSI) that assesses the adequacy of school environments for students aged 9-19. Methods : The Korean version of the SSI, which was completed via a translation-reverse translation process, was verified by conducting a questionnaire on category suitability two times with 35 experts. Results : The content validity index (CVI) for the entire K-SSI tool was .90 in the first test. The "Maps and diagrams" measurement in reading items and the "Taking a shower" measurement in sports activities were both below .75. A second round of verification was conducted after the CVI was modified. As a result, the secondary verification CVI results were further raised to .93. Conclusion : This study confirmed that the K-SSI contains items that are appropriate to Korean culture; it has been proven to have high content validity. Future continuous research and clinical use are required to study the validity and reliability of the K-SSI. Further, this tool should also be applied to students with diverse disabilities who face difficulties in school settings.

Purpose: The aim of the study was to verify the validity and reliability of the Korean version of the General Attitudes towards Artificial Intelligence Scale (GAAIS-K) for nursing students. Methods: Data from 235 participants were collected from April 12 to April 26, 2022. A total of 230 participants' data were analyzed. The data were analyzed for content, discriminant, known-groups, and construct validity using content validity index, correlation coefficient, and confirmatory factor analyses. The reliability of the GAAIS-K was examined using internal consistency and test-retest analyses. Results: The expert-rated content validity index was ≥.80. The sub-scales of the GAAIS-K were moderately correlated with attitude toward accepting technology, indicative of its discriminant validity. The male students' positive attitude score was significantly higher than that of the female students, satisfying the known-groups validity. Cronbach's α for the scale was .86 (positive) and .74 (negative), and the intra-class correlation coefficient for the two-week test-retest reliability was .86 (positive) and .60 (negative). The scores for positive and negative attitudes were 3.68±0.46 and 3.05±0.55. Conclusion: This study shows that the GAAIS-K is a valid and reliable instrument for assessing nursing students. Additional research is recommended to continue the evaluation of the GAAIS-K with a focus on healthcare settings.

This study was to evaluate the suitability of scientific questions as qualification examination for high school graduation by content validity and item response with three examinees and two preliminary examinees. As a result, scientific questions were concentrated on two units of six units of total, and application appeared to be lacking problem area by 8% compared to understanding and application. Examinees and preliminary examinees chose correct answers most by hap or guess, sometimes by experience or common sense, and the least by scientific concept. In addition, they could chose correct answers by hap or guess because there were words that implied the correct answer in questions and answers, or because they could compared and/or analyzed questions and answers. With these results, two proposals were suggested as follows; (1) scientific questions of qualification examination for high school graduation should measure basic scientific literacy. (2) specific criteria for science literacy in qualification examination for high school graduation should be set.

Purpose: The purpose of this study was to evaluate the psychometric properties of the Korean version of the Alzheimer's Disease Knowledge Scale (ADKS-K) to determine its applicability to Korean adults. Methods: Cross-cultural validity was performed according to Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN). The Kuder-Richardson Formula 20 for internal consistency and Intraclass Correlation Coefficient (ICC) for test-retest reliability were conducted. Content validity, criterion related validity and construct validity were evaluated. The Classical Test Theory (CTT) model and the Item Response Theory (IRT) model were applied in performing the item analysis. Results: The KR 20 was .71, and the ICC was .90, indicating that the ADKS-K has internal consistency and stability reliability. Thirty items of the ADKS-K had significant Content Validity Ratio (CVR) values, i.e., mean of 0.82 and range of 0.60~1.00. Mean item difficulty and discrimination indices calculated by TestAn program were 0.63 and 0.23, respectively. Mean item difficulty and discrimination indices calculated by BayesiAn program were -0.60 and 0.77, respectively. These tests indicate that ADKS-K has an acceptable level of difficulty and discriminating efficiency. Conclusion: Results suggest that ADKS-K has the potential to be a proper instrument for assessing AD knowledge in Korean adults.

Purpose: This study was done to evaluate the Lasater Clinical Judgement Rubric for use with Korean nursing students. Methods: A methodological study was used to validate the rubric developed by Lasater to assess clinical judgment during nursing simulation. Participants were 34 nursing students at K University in Seoul. Between February and May, 2012, analysis was done of 91 video clips recording performance during simulation. Results: Findings showed reliability and validity of the rubric. For internal consistency, Cronbach's ${\alpha}$ score was .884 and intraclass correlation coefficient was .839, which established reliability. The rubric was validated using the exploratory factor analysis and content validity. The content validity score was 83%, establishing the appropriateness and readiness of the tool. Factor analysis showed that noticing, responding, and reflecting domains had Eigen values of 2.669, 1.991, and 2.912, respectively and were bound, but unlike the original tool in which four factors noticing, interpretation, responding, and reflecting domains were bound. Conclusion: Results of the study indicate that the rubric shows acceptable reliability and validity in Korean nursing students. This evaluation tool for nursing simulation allows nursing faculty to objectively evaluate students' clinical judgment as well as students to reflect on their clinical judgment process during simulation.
