Healthcare workers play a crucial role in supporting COVID-19 vaccination as they are the most trusted source of information to the public population. Assessing the healthcare workers' hesitancy towards COVID-19 vaccination is pertinent, however, there are limited validated tools to measure their hesitancy on COVID-19 vaccines. This study aims to adapt and validate the first COVID-19 hesitancy scale among healthcare workers in Malaysia.
This study adapted and translated the Vaccine Hesitancy Scale (VHS) developed by the WHO SAGE Working Group. The scale underwent a sequential validation process, including back-back translation, content, face, and construct validity for Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). The reliability was tested using internal consistency (Cronbach's alpha composite reliability (CR) and average variance extracted (AVE)).
The data for EFA and CFA were completed by a separate sample of 125 and 300 HCWs, respectively. The EFA analysis of the C19-VHS-M scale was unidimensional with 10 items. A further CFA analysis revealed a uniform set of nine items with acceptable goodness fit indices (comparative fit index = 0.997, Tucker-Lewis index = 0.995, incremental fit index = 0.997, chi-squared/degree of freedom = 1.352, and root mean square error of approximation = 0.034). The Cronbach's alpha, CR and AVE results were 0.953, 0.95 and 0.70, respectively.
The questionnaire was valid and reliable for use in the Malay language.
医疗工作者在支持 COVID-19 疫苗接种方面发挥着至关重要的作用，因为他们是公众最信任的信息来源。评估医疗工作者对 COVID-19 疫苗的犹豫态度至关重要，然而，目前用于衡量他们对 COVID-19 疫苗犹豫不决的有效工具有限。本研究旨在适应当地情况并验证马来西亚医疗工作者的 COVID-19 犹豫量表。
本研究适应当地情况并翻译了世界卫生组织 SAGE 工作组开发的疫苗犹豫量表（VHS）。该量表经历了一系列的验证过程，包括反向翻译、内容、表面和结构有效性的探索性因素分析（EFA）和验证性因素分析（CFA）。可靠性通过内部一致性（Cronbach's alpha 综合可靠性（CR）和平均方差提取（AVE））进行测试。
EFA 和 CFA 的数据分别由 125 名和 300 名 HCWs 完成。C19-VHS-M 量表的 EFA 分析为单维，包含 10 个项目。进一步的 CFA 分析显示，一套九个项目具有可接受的良好拟合指数（比较拟合指数=0.997，塔克-刘易斯指数=0.995，增量拟合指数=0.997，卡方/自由度=1.352，和均方根误差逼近=0.034）。Cronbach's alpha、CR 和 AVE 的结果分别为 0.953、0.95 和 0.70。
该问卷在马来语中是有效和可靠的。
