Development and psychometric properties of the public attitude towards vaccination scale – Health belief model

다국어 초록 (Multilingual Abstract)

The aim of this study was to develop and psychometrically evaluate the Public Attitude Towards Vaccination Scale – Health Belief Model.
A methodological and prospective psychometric study.
A three‐phase construct was used to develop the Public Attitude Towards Vaccination Scale – Health Belief Model and to determine its psychometric properties: (1) creation of the item pool/conceptualization; (2) evaluation of the items; and (3) psychometric evaluation. This scale was tested using the construct validity (exploratory and confirmatory factor analyses) and the reliability analysis. A psychometric assessment of the scale was conducted with 586 individuals. Data were collected between January ‐ April 2018.
Items of the scale were obtained by appraising the literature concerning vaccination and the other Health Belief Model scale and conducting interviews with mothers. The content validity ratio of this scale calculated according to experts’ opinions ranged between 0.769 and 1.00. According to the exploratory factor analysis, there were five factors with an eigenvalue higher than 1 in the scale. These five factors accounted for 68.9% of the total variance. In confirmatory factor analysis, values of fit indices were excellent or acceptable. This scale had high internal consistency and test–retest reliability.
This study successfully developed the Public Attitude Towards Vaccination Scale – Health Belief Model. In addition to researchers, this scale can be used by nurses while providing counselling for people with vaccine hesitancy/refusal.
This measurement tool can be used to understand and address ‘vaccine hesitancy’ by researchers. The results of the research using this measurement tool will provide valuable information to policymakers for preventing vaccine hesitancy. The validity and reliability of this scale can easily be conducted in different languages.
本研究旨在揭示且从心理测量学角度评估公众对疫苗接种量表‐健康信念模型的态度。
一项方法学和前瞻性心理测量研究
采用三阶段结构来揭示公众对疫苗接种量表‐健康信念模型的态度,并确定其心理测量特性:(1)创建项目库/概念化;(2)项目评估;和(3)心理测量评估。该量表采用结构效度(探索性和验证性因子分析)和信度分析进行检验。对586例进行了心理测量学评估。数据收集时间为2018年1月至4月。
通过评价疫苗接种相关文献和其他健康信念模型量表以及与父母的访谈,获得量表项目。根据专家意见计算该量表,得出内容效度比在0.769‐1.00之间。根据探索性因子分析,发现该量表中共有5个因子的特征值大于1。这五个因子占总方差的68.9%。在验证性因子分析中,拟合指数的值为优或可接受。该量表具有较高的内部一致性和重测信度。
本研究成功揭示了公众对疫苗接种量表‐健康信念模型的态度。除了研究人员,临床科研护士亦可使用该量表,同时为那些对疫苗接种犹豫不决/拒绝疫苗接种的人提供咨询建议。
研究人员可利用本测量工具来理解和解决‘疫苗接种犹豫症’。使用该测量工具的研究结果将为决策者提供有关预防‘疫苗接种犹豫症’的有价值信息。可使用不同的语言来评估该量表的效度和信度。
