Abstract

Due to the effect of coronavirus disease 2019 (COVID-19) outbreak on the continuation, schedule, and efficiency of radiation therapy, this study aimed to investigate the reliability and validity of the COVID-19 Safety Measures (CSM) questionnaire at the radiation therapy center. In this analytical cross-sectional study, which all personnel of the radiation therapy center (20 people) participated, the validity and reliability of the 16-item CSM questionnaire were investigated. Cultural adaptation, face validity, content validity, test-retest reliability, and internal consistency were evaluated. For face and content validity, impact score, content validity ratio, and content validity index (CVR and CVI) were calculated, respectively. Also, internal consistency and stability reliability were calculated with Kuder–Richardson (KR20) alpha and Pearson correlation coefficient and intraclass correlation (ICC), respectively. Data analysis was performed using Statistical Package for the Social Sciences (SPSS) 24 with a significant level of 5%. Out of 20 employees, 70% (14 people) were female, 75% (15 people) were married and the mean age (SD) was 32.4 (6.35) years. Scale-based Kuder–Richardson alpha, S-CVI, ICC, and confidence interval were 0.79, 0.97, 0.68, and 0.38–0.89, respectively. The validity and reliability of the 16-item CSM questionnaire were confirmed. Therefore, the application of this scale is recommended.

放射治疗中心员工 COVID-19 安全措施问卷的心理测量特性

由于冠状病毒病 2019（COVID-19）疫情对放射治疗的持续性、进度和效率产生了影响，本研究旨在调查放射治疗中心 COVID-19 安全措施（CSM）问卷的可靠性和有效性。在这项分析性横断面研究中，放射治疗中心的所有人员（20 人）都参与了研究，对 16 个项目的 CSM 问卷的有效性和可靠性进行了调查。对问卷的文化适应性、表面效度、内容效度、重测信度和内部一致性进行了评估。在面效度和内容效度方面，分别计算了影响得分、内容效度比率和内容效度指数（CVR 和 CVI）。此外，还分别用 Kuder-Richardson（KR20）α、皮尔逊相关系数和类内相关（ICC）计算了内部一致性和稳定性可靠性。数据分析采用社会科学统计软件包（SPSS）24 进行，显著性水平为 5%。在 20 名员工中，70%（14 人）为女性，75%（15 人）已婚，平均年龄（SD）为 32.4（6.35）岁。量表的 Kuder-Richardson α、S-CVI、ICC 和置信区间分别为 0.79、0.97、0.68 和 0.38-0.89。 16 项 CSM 问卷的有效性和可靠性得到了证实。因此，建议应用该量表。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
