Avoiding unnecessary travel and reducing the number of essential travels are among the effective strategies for preventing the spread of COVID-19 during the pandemic. Given that it is impossible to avoid essential travel, health protocols should be observed to prevent disease transmission. The extent to which health protocols are observed during the trip should be accurately assessed by a valid questionnaire. Therefore, this study aims to develop and validate a questionnaire to assess compliance with COVID-19 prevention protocols during travel.
In this cross-sectional study, 285 individuals were selected from six provinces using the cluster sampling method in May and June 2021. The Content Validity Ratio (CVR) and Content Validity Index (CVI) were calculated using the comments of 12 external experts. The exploratory factor analysis (EFA), with principal component factor in the extraction method and Varimax rotation, were applied to determine construct validity. Cronbach's alpha was employed to assess internal consistency and the Spearman-Brown correlation coefficient was computed for test-retest reliability.
In the content validity phase, the I-CVIs for all items were acceptable, but due to a low CVR value (below 0.56), one question was eliminated. As a result of EFA for construct validity, two factors were extracted that justified 61.8% of the variance. Cronbach's alpha coefficient of the questionnaire, with 10 items, was 0.83. The Spearman-Brown correlation coefficient was 0.911 which confirmed the stability of the questionnaire at an excellent level.
This questionnaire is a valid tool with good validity and reliability for assessing compliance with health protocols in travel during the COVID-19 pandemic.
在疫情期间，避免不必要的旅行以及减少必要旅行的次数是预防新冠病毒传播的有效策略。鉴于无法避免必要旅行，应遵守健康协议以防止疾病传播。旅行期间遵守健康协议的程度应由一份有效的问卷准确评估。因此，本研究旨在开发并验证一份问卷，以评估旅行期间对新冠病毒预防协议的遵守情况。
在这项横断面研究中，2021年5月和6月采用整群抽样法从六个省份选取了285名个体。利用12名外部专家的意见计算内容效度比（CVR）和内容效度指数（CVI）。采用探索性因子分析（EFA），提取方法为主要成分因子法并进行方差最大化旋转，以确定结构效度。采用克朗巴哈α系数评估内部一致性，并计算斯皮尔曼-布朗相关系数以检验重测信度。
在内容效度阶段，所有条目的I-CVI均可接受，但由于CVR值较低（低于0.56），删除了一个问题。作为结构效度的EFA结果，提取了两个因子，解释了61.8%的方差。该问卷有10个条目，克朗巴哈α系数为0.83。斯皮尔曼-布朗相关系数为0.911，证实该问卷在优秀水平上具有稳定性。
该问卷是评估新冠疫情期间旅行中健康协议遵守情况的有效工具，具有良好的效度和信度。
