(1) Background: Vaccine literacy (VL) of the public is crucial to deal with anti-vaccination rhetoric. This study aims to (1) develop a Chinese COVID-19 Vaccine Literacy Scale and examine the factor structure and psychometric characteristics, and (2) explore the association between COVID-19 VL and sociodemographic characteristics and other variables; (2) Methods: An online cross-sectional survey was conducted among 362 Chinese residents from 23 May 2022 to 31 May 2022 using snowball sampling; (3) Results: Exploratory and confirmatory factor analysis indicated that the scale of 15 items, consisting of three factors, functional, interactive and critical vaccine literacy, explained 63.3% of the total variance. Cronbach's α coefficient was 0.885 for the overall scale: 0.838, 0.891, and 0.857 for three subscales, respectively. The results showed a medium level of vaccine literacy (M = 3.71, SD = 0.72) and significant differences among functional, interactive, and critical vaccine literacy ( < 0.001). The level of vaccine literacy grew with the level of education ( < 0.001) and age ( = 0.049). Men, participants who were single, or those living in rural areas had a lower level of vaccine literacy; (4) Conclusions: The Chinese COVID-19 VL Scale has adequate validity and reliability for assessing vaccine literacy among Chinese residents. A deep understanding of the factors that affect vaccine literacy is needed.
(1) 背景：公众的疫苗素养（VL）对于应对反疫苗言论至关重要。本研究旨在：(1) 开发一种中文 COVID-19 疫苗素养量表，并检验其结构和心理测量特性；(2) 探讨 COVID-19 疫苗素养与社会人口特征和其他变量之间的关系。(2) 方法：于 2022 年 5 月 23 日至 5 月 31 日，采用滚雪球抽样法，对 362 名中国居民进行了一项在线横断面调查。(3) 结果：探索性和验证性因素分析表明，该量表由 15 个项目组成，包含三个维度，分别为功能性、交互性和批判性疫苗素养，可解释总方差的 63.3%。总量表的 Cronbach's α 系数为 0.885：三个分量表的 Cronbach's α 系数分别为 0.838、0.891 和 0.857。结果表明，疫苗素养水平处于中等（M = 3.71，SD = 0.72），且在功能性、交互性和批判性疫苗素养方面存在显著差异（< 0.001）。疫苗素养水平随教育程度（< 0.001）和年龄（= 0.049）的提高而提高。男性、单身、居住在农村地区的参与者疫苗素养水平较低。(4) 结论：中文 COVID-19 疫苗素养量表具有评估中国居民疫苗素养的充分有效性和可靠性。需要深入了解影响疫苗素养的因素。
