The coronavirus disease 2019 (COVID-19) pandemic has prompted the further virtualization of medical education. The satisfaction level of specific users such as cardiology residents with virtual education can augment its quality; hence, the significance of a valid and reliable questionnaire to obtain feedback is needed. This study aimed to design and measure validity and reliability of a satisfaction questionnaire for virtual education of cardiology residents during COVID-19 pandemic.
In this cross-sectional study, a self-administered questionnaire was developed by the faculty members of Rajaie Cardiovascular Medical and Research Center. Reliability was tested utilizing Cronbach's alpha and intercorrelation which was tested using Pearson's correlation coefficient test (ICC). Factor analysis was done by the Kaiser-Meyer-Olkin measure of sampling adequacy and Bartlett's sphericity test. The statistical analyses were performed with the SPSS software version 22.
The face validity index was determined via an assessment of the relevance, clarity, and simplicity of each item, and values >0.79 were accepted. The total Cronbach's alpha coefficient was calculated 0.93. Concerning test-retest reliability, the correlation between two rounds of evaluation was >80 ( > 0.001) and ICC was 0.99 ( = 0.001). The content validity evaluation yielded an index of 0.95 and a ratio of 0.91. The principal component factor analysis, conducted to investigate construct validity, generated four domains.
The study results confirmed the validity and reliability of the designed questionnaire to evaluate the level of satisfaction of cardiology residents with virtual learning in COVID-19 pandemic.
2019年冠状病毒病（COVID-19）大流行促使医学教育进一步虚拟化。心脏病学住院医师等特定用户对虚拟教育的满意度水平可提升其质量；因此，需要一份有效且可靠的问卷来获取反馈。本研究旨在设计并测量一份关于COVID-19大流行期间心脏病学住院医师虚拟教育满意度问卷的有效性和可靠性。
在这项横断面研究中，拉贾伊心血管医学与研究中心的教员们编制了一份自填式问卷。利用克朗巴哈系数和相互关系来测试信度，其中相互关系使用皮尔逊相关系数检验（ICC）进行测试。通过凯泽 - 迈耶 - 奥尔金抽样适当性度量和巴特利特球形度检验进行因子分析。使用SPSS 22软件进行统计分析。
通过评估每个条目的相关性、清晰度和简单性来确定表面效度指数，大于0.79的值被接受。计算得出总克朗巴哈系数为0.93。关于重测信度，两轮评估之间的相关性大于80（>0.001），ICC为0.99（=0.001）。内容效度评估得出指数为0.95，比率为0.91。为调查结构效度而进行的主成分因子分析产生了四个领域。
研究结果证实了所设计问卷在评估COVID-19大流行期间心脏病学住院医师对虚拟学习满意度水平方面的有效性和可靠性。
