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.

Background: Patient safety is one of the key components of nursing care for cancer cases. Valid and reliable context-based instruments are necessary for accurate evaluation of patient safety in oncology units. The aim of the present study was to develop and evaluate the psychometric properties of the Patient Safety Violation Scale in medical oncology units in Iran. Materials and Methods: In this methodological study, a pool of 58 items was generated through reviewing the existing literature. The validity of the 58-item scale was assessed through calculating impact score, content validity ratio, and content validity index for its items as well as conducting exploratory factor analysis. The reliability of the scale was evaluated by assessing its internal consistency and testretest stability. Study sample consisted of 300 oncology nurses who were recruited from thirteen teaching hospitals affiliated to Tehran University of Medical Sciences, Tehran, Iran. Results: Sixteen items were excluded from the scale due to having low impact scores, content validity ratios, or content validity indices. In exploratory factor analysis, the remaining 42 items were loaded on five factors including patient fall, verification of patientidentity, harm during care delivery, delay in care delivery, and medication errors. These five factors explained 62% of the total variance. The Cronbach's alpha of the scale and the test-retest interclass correlation coefficient were equal to 0.933 and 0.92, respectively. Conclusions: The 42-item Patient Safety Violation Scale is a simple and short scale which has acceptable validity and reliability. Consequently, it can be used for assessing patient safety in clinical settings such as medical oncology units and for research projects.

Objectives: The objective of this study was to investigate the validity of the preliminary critical pathway of integrative medicine to improve the quality of life of lung cancer patients who received chemotherapy. Methods: The vertical axis of the preliminary critical pathway of integrated medicine consisted of nine domains: assessment, treatment, activity, consult, diet, medication, Korean medical examination, education, and others. The frame of the horizontal axis was the date from hospitalization to discharge. A total of 105 items in this preliminary critical pathway were validated by an expert group from October 28, 2016 to November 4, 2016. A total of ten experts from two different medical institutions participated in the validity test, using the four-point Content Validity Index (CVI) scale. The items with validity of greater than 80% were considered as significant. Results: The analysis of the content validity of 105 items showed 102 items with greater than 80% agreement. Assessment, treatment, consult, diet, medication, and education showed 100% agreement. Only three items showed a low validity (62.5%). Based on additional comments, the preliminary critical pathway of integrative medicine has been supplemented. Conclusions: This study suggests the possibility of using the integrated medical critical pathway for patients with lung cancer who received chemotherapy.

Background: The aim of this study was to evaluate the quality of the Second Korean Working Conditions Survey (KWCS), focusing on its validity and reliability. Methods: The external validity was evaluated by the assessment of sampling procedures and the response rate, in order to investigate the representativeness of the sample. The content validity was evaluated by the assessment of the development of the questionnaire, and the consistency of questions for the selected construct. The test-retest method was used to evaluate the reliability by means of a phone call survey of 30% of the respondents, who were randomly selected. The respondents' satisfaction regarding the survey procedures and interview time were analyzed to evaluate the quality of survey data. Results: The external validity was assured by an acceptable sampling procedure, rigid multi-stage stratified cluster random sampling. The content validity was also guaranteed by a reasonable procedure for the development of the questionnaire with a pretest. The internal consistency of the questions for work autonomy was maintained, with 0.738 of Cronbach's alpha. The response rate of 36% was lower than that of the European Working Conditions Survey (EWCS), with a contact rate of 66%, compared to 76% for the EWCS. The matching rates of the five retested questions were more than 98% reliable. Conclusion: The quality of the second KWCS was assured by the high external and content validity and reliability. The rigid sampling procedure and development of the questionnaire contributed to quality assurance. The high level of reliability may be guaranteed by the sophisticated field survey procedures and the development of a technical manual for interviewers. The technical strategies for a high response rate should be developed for future surveys.

Background: Safety culture, acting as the oil necessary in an efficient safety management system, has its own weaknesses in the current conceptualization and utilization in practice. As a new approach, resilience safety culture (RSC) has been proposed to reduce these weaknesses and improve safety culture; however, it requires a valid and reliable instrument to be measured. This study aimed at evaluating the reliability and validity of such an instrument in measuring the RSC in sociotechnical systems. Methods: The researchers designed an instrument based on resilience engineering principles and safety culture as the first instrument to measure the RSC. The RSC instrument was distributed among 354 staff members from 12 units of an anonymous petrochemical plant through hand delivery. Content validity, confirmatory, and exploratory factor analysis were used to examine the construct validity, and Cronbach alpha and test-retest were employed to examine the reliability of the instrument. Results: The results of the content validity index and content validity ratio were calculated as 0.97 and 0.83, respectively. The explanatory factor analysis showed 14 factors with 68.29% total variance and 0.88 Kaiser-Meyer-Olkin index. The results were also confirmed with confirmatory factor analysis (relative Chi-square = 2453.49, Root Mean Square Error of Approximation = 0.04). The reliability of the RSC instrument, as measured by internal consistency, was found to be satisfactory (Cronbach ${\alpha}=0.94$). The results of test-retest reliability was r = 0.85, p < 0.001. Conclusion: The results of the study suggest that the measure shows acceptable validity and reliability.

This study has been analyzed to write an ideal training evaluation table after analyzing validity of content organization and assigning score of evaluating elements of clinical practice of Dept. of dental technology. 220 junior students who are studying dental technology in D university in Daegu were questioned to analyze the relationship of content organization and score of clinical practice evaluation table. The corrected material has been inspected by SAS V8 for Windows. The results are as following. 1. The validity of content organization of clinical practice evaluation table has a result which can be reliable over than 70% but the validity of score shows low reliance. c 2. The validity of content organization of detail elements of clinical practice evaluation shows that overuse of material and attentiveness(3.78) and responsibility (3.60) are high response but in score organization, the validity shows that safety measure(2.36) when controling machines, arrangement(2.98) after use and ability (2.98) of solving problems are very low. 3. In the elements without interpersonal relation, it shows that those are related to each other. its grading is p < 0.01 so it appears to be meaningful. 4. In result of analyzing the effect to 'studying amount' mark in clinical practice evaluation mark, it appears the element of attitude for job to affect it. And in result of analyzing the effect to 'training attitude' mark, it appears the element of 'controling machines' to affect it. For these results, to be a better evaluation tool, it should be modified by continuous research with arranging evaluation elements to be marked differently in between elements.

Purpose: This study aims to develop the Korean version of Presenteeism Scale for Students and verify its reliability and validity. Methods: This study conducted a survey with 320 undergraduate students who are attending nursing departments at three universities. The survey was conducted twice, from June 1 to August 31, 2017. Results: The Cronbach's α of K-PSS was .70 indicating high reliability. As a result of testing the content validity of K-PSS was verified by calculating the Item level-Content Validity Index (I-CVI) of .87. The correlation between Medical Outcome Study 36-item Short Form Health Survey (SF-36) score and Work Impairment Score (WIS), Work Output Score (WOS), Hours of absenteeism (HA) was analyzed to verify the concurrent validity of K-PSS. SF-36 score was correlated with WIS, WOS, HA. To test the differentiated validity of K-PSS, a total of 38 subjects were assessed by the paired t-test. As a result, only WIS score showed a significant difference between pre-test and post-test. Conclusion: Since the reliability and validity of the K-PSS developed through this study have been verified, it is expected to be used in various studies related to the presenteeism of students.

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.
