目的筛选评价呼吸道传染病健康素养的指标,确定评价指标和维度的权重系数,建立并评估呼吸道传染病健康素养的综合评价体系。方法依据性别、年龄、教育程度较均衡的配额抽样方法在北京市海淀区随机抽取了515名成人进行计算机辅助技术的问卷调查。通过难度、区分度、信度和效度检验筛选出测评指标;利用归一化法和变异系数法分别得到主观权重和客观权重,并利用综合指数模型最终构建评价体系。结果共筛选39个指标,从知识、行为/行为意向、能力3个维度评价呼吸道传染病健康素养。各指标难度P均在0.5～0.9范围内,区分度D>0.3,3个维度的内部一致性系数分别为0.782、0.657和0.842,赋权重后综合评价一致性信度达到0.872,二次探索性因子分析结果显示评价体系符合设定维度的划分(KMO=0.821,可解释方差为54.08%),以验证性因子分析进行验证,拟合优度良好(IFI=0.905,TLI=0.873,CFI=0.905,RMSEA=0.065)。结论本研究所开发的呼吸道传染病健康素养评价工具及体系的难易度、区分度、信度、效度均较好,可以用来测评公众的呼吸道传染病健康素养水平。
Objective To screen the index of health literacy of respiratory infectious diseases, determine the weight coefficient of evaluation index and dimension, and establish and evaluate the comprehensive evaluation system of health literacy of respiratory infectious diseases. Methods A total of 515 adults were randomly selected from the Haidian District of Beijing according to the quota sampling method of gender, age and educational level to conduct computer aided questionnaire survey. The evaluation indexes are screened out by testing the degree of difficulty, discrimination, reliability and validity. Subjective weights and objective weights are obtained respectively by using the normalization method and the variation coefficient method. Finally, the evaluation index system is constructed by using the comprehensive index model. Results A total of 39 indicators were screened, and the health literacy of respiratory infectious diseases was evaluated from the three dimensions of knowledge, behavior / behavior intention and ability. The indexes of difficulty P are in the range of 0.5 ~ 0.9, the degree of difference D> 0.3, the internal consistency coefficient of three dimensions are 0.782, 0.657 and 0.842 respectively, and the reliability of comprehensive evaluation after weighting is 0.872. The second exploratory The result of factor analysis showed that the evaluation system accorded with the division of set dimension (KMO = 0.821, explainable variance was 54.08%), and verified by confirmatory factor analysis, the goodness of fit (IFI = 0.905, TLI = 0.873, CFI = 0.905 , RMSEA = 0.065). Conclusion The ease, discrimination, reliability and validity of the tools and system for evaluating health literacy of respiratory infectious diseases developed in this study are good and can be used to evaluate the public health literacy level of respiratory infectious diseases.
