摘　　要：目的评价中国居民传染病健康素养测评量表(IDSHL)的结构效度。方法使用2015年3—5月在我国3省的3个市随机抽取的4 499名15～60岁城乡居民的传染病健康素养数据资料,运用AMOS 21.0软件构建CFA测量模型进行分析。结果验证性因子分析的模型适配度指标:GFI=0.969, AGFI=0.962, RMR=0.038,RMSEA=0.038,SRMR=0.032,TLI=0.925,CFI=0.934,NFI=0.925,RFI=0.915,IFI=0.934,PGFI=0.778,PNFI=0.813,PCFI=0.821,CN=700。22个测量变量的因子负荷量(λ)为0.160～0.732。结论 IDSHL量表对维度划分基本合理,该量表作为中国居民传染病健康素养的测量和传染病干预效果评价的测量工具具有较好的结构效度。Objective To evaluate the construct validity of an infectious disease-specific health literacy(IDSHL) scale for Chinese residents. Methods We used a data set on 4 499 adult residents(15 – 60 years old) selected with random cluster sampling in three cities of three provinces across China from March to May 2015. Confirmatory factor analysis(CFA) was used to assess psychometric properties of the IDSHL scale with AMOS 21.0. Results Confirmatory factor analyses revealed a good fitness of the constructed model with the data and the indicators of the constructed model were as following:goodness-of-fit index(GFI)= 0.969, adjusted goodness-of-fit index(AGFI)= 0.962, root mean square residual(RMR)=0.038, root mean square error of approximation(RMSEA)= 0.038, standardized root mean square residual(SRMR)= 0.032,Tacker-Lewis index(TLI)= 0.925, comparative-fit index(CFI)= 0.934, normed fit index(NFI)= 0.925, relative fitness index(RFI)= 0.915, incremental fit index(IFI)= 0.934, parsimony goodness-of-fit index(PGFI)= 0.778, parsimony normed fit index(PNFI)= 0.813, parsimony-adjusted comparative fit index(PCFI)= 0.821, critical number(CN)= 700. The factor loading for 22 measurement variables ranged from 0.160 to 0.732. Conclusion The classification of dimensions for the IDSHL scale is reasonable and the scale is of good construct validity in measuring infectious disease-specific health literacy and the efficacy of intervention on infectious disease among Chinese residents.
