居民卫生应急素养评价问卷编制及信效度检验

Development and validation of health emergency literacy assessment questionnaire for residents

目的编制居民卫生应急素养评价问卷并检验其信效度,为研究居民卫生应急素养提供评估工具。方法采用文献检索、专家咨询方法确定理论框架和指标体系,根据指标体系编制问卷条目。采用多阶段随机和人口规模成比例相结合的抽样方法抽取1200名徐汇区居民进行问卷调查,以此1200例样本对初始问卷进行项目分析,形成正式测评问卷。对经过项目分析筛选后保留的条目进行内部一致性信度、内容效度和结构效度分析。选取其中50例样本进行重测信度分析。结果最终构建的居民卫生应急素养评价问卷包含功能性、互动性和批判性素养3个维度,共26个条目。总问卷的Cronbach'sα系数为0.740,各维度Cronbach'sα系数区间为0.607~0.807;总问卷的分半信度为0.797;总问卷的重测信度为0.741,各维度的重测信度区间为0.676~0.712。问卷各维度得分与总分的相关系数区间为0.499~0.812(P<0.05)。验证性因子分析结果显示,χ^(2)/df=3.642,RMSEA=0.047,GFI=0.929,AGFI=0.915,CFI=0.876。结论本研究编制的问卷具有良好的信效度,可作为评价居民卫生应急素养的定量工具。

Objective To develop a health emergency literacy assessment questionnaire and to examine its reliability and validity of the questionnaire for providing a tool for research on health emergency literacy among residents.Methods Based on literature review and expert consultation,we established a theoretical framework and index system.And the items of questionnaire were developed based on the established index system.A total of 1200 residents in Xuhui district were selected by multi-stage random and proportional to population size sampling to conduct a questionnaire survey.The data were used for item analysis,and then initial questionnaire was modified to form a formal evaluation questionnaire.The selected items retained after item analysis were brought into the homogeneity reliability,content validity and structural validity.Fifty residents from 1200 residents were re-selected for retest reliability analysis.Results The final assessment questionnaire included three dimensions with a total of 26 items:functional,interactive and critical health literacy.The value of Cronbach sαof total questionnaire was 0.740,which in three dimensions were 0.607-0.807.The value of split-half reliability of total questionnaire was 0.797.The value of retest reliability of total questionnaire was 0.741,which in three dimensions were0.676-0.712.The correlation coefficient value of total questionnaire and each sub-questionnaire were between 0.499-0.812(P<0.01).The confirmatory factor analysis showedχ^(2)/df=3.642,RMSEA=0.047,GFI=0.929,AGFI=0.915,CFI=0.876.Conclusion The evaluation index system for residents'health emergency literacy has good reliability and validity and could be used for estimating residents health emergency literacy.
