目的 基于行为和社会驱动因素(behavioural and social drivers,BeSD)框架设计老年人流感疫苗接种意愿影响因素调查问卷,并评价其信度与效度.方法 基于BeSD框架,采用文献综述、两轮专家咨询和认知性访谈的方法拟定问卷,并在河南省焦作市对问卷进行实地调查验证.调查对象采取分层多阶段抽样方法获得,按经济水平分层抽样共获得2个区(县),分别选择1个社区和1个行政村,共4个调查单位,并采取方便抽样的方法从中选定441名调查对象.使用R4.3.2软件对调查对象的社会人口学特征进行描述性分析,并对问卷BeSD影响因素部分进行内部一致性信度、重测信度、条目与所在维度相关性以及结构效度分析.结果 问卷经专家评定,内容效度良好.因子分析得到5个公因子,累计方差解释率为48.20％,且基本与预期设计一致,结构效度可以接受.问卷各维度ω系数范围为0.60～0.89,重测信度系数为0.99～1.00,所有条目的重测信度系数为0.93～1.00,信度良好.结论 基于BeSD框架设计的调查问卷信效度较好,适用于我国老年人流感疫苗接种意愿各影响因素的调查.
Development of a questionnaire on influenza vaccine acceptance among the elderly based on the behavioral and social driver framework
Objective This study aimed to design a questionnaire based on the Behavioral and Social Driver(BeSD)framework to investigate factors influencing influenza vaccine acceptance among the elderly and evaluate its reliability and validity.Methods The questionnaire was developed based on the BeSD framework using a lit-erature review,two rounds of expert consultation,and cognitive interviews.It was field-tested in Jiaozuo City,Henan Province,China.Participants were selected using a stratified multi-stage sampling approach.The first stage involved selecting two counties based on economic level,from which one community and one village were chosen,resulting in four survey units.Then 441 participants were selected through the convenience sampling method.A descriptive analysis of participants'socio-demographic characteristics was conducted using R 4.3.2 software.Internal consistency reliability,test-retest reliability,item-dimension correlations,and structural va-lidity were assessed for the BeSD-related sections of the questionnaire.Results The questionnaire demon-strated good content validity as assessed by experts.Exploratory factor analysis revealed five common factors,explaining 48.20％of the variance and aligning with the expected design.The structural validity of the question-naire was deemed acceptable.The omega coefficients for each dimension ranged from 0.60 to 0.89,and test-retest reliability coefficients ranged from 0.99 to 1.00.All items showed good test-retest reliability coefficients ranging from 0.93 to 1.00.Conclusions The questionnaire designed based on the BeSD framework showed good reliability and validity,making it suitable for investigating factors influencing influenza vaccine acceptance among the elderly in China.
