亚健康评定量表评价广州市城镇居民的亚健康状况的信效度

Reliability and Validity of Sub-Health Measurement Scale Version 1.0 in Evaluation of Sub-Health of Urban Residents in Guangzhou

目的：检验第一版亚健康评定量表（SHMS V1.0）测量广州市城镇居民亚健康状况的信效度。方法：应用 SHMS V1.0对917名城镇居民进行现场测试。结果：总量表的 Cronbach’s α系数为0.927,分半信度为0.871。量表各因子之间与其子量表分的相关系数为0.576~0.916（P 〈0.01）,39个条目与其所属因子得分的相关性均较大（0.643~0.879）,与 SF-36总分的相关系数为0.739（P 〈0.01）。经探索性因子分析,KMO 统计量为0.919, Bartlett 球型检验结果为χ2=15512.758,υ=595,共提取出7个公因子,与理论构想基本吻合。经验证性因子分析,χ2=2330.101（P =0.000）,CMIN/DF=4.524,GFI =0.855,NFI =0.846,CFI =0.875,AGFI =0.832,RMSEA =0.061,说明该模型的拟合效果理想。结论：SHMS V1.0可以反映出广州市城镇居民亚健康状况,具有较好的信度和效度。

Objective：To assess the reliability and validity of Sub-Health Measurement Scale Version 1.0（SHMS V1.0）in the evaluation of sub-health of town dweller in Guangzhou.Methods：The spot trial was performed among 91 7 town dweller in Guangzhou for the study of reliability and validity of SHMS V1.0.Results：The Cronbach ’sαco-efficient was 0.927 and the split-half reliability 0.871.There was a high correlation between each item of SHMS V 1.0 and its dimension（r =0.576~0.91 6,P 〈0.01）,39 items and the factors they belonged to had larger correlation（r=0.643~0.879,P 〈0.01）,and the scores of SHMS V1.0 had significant correlation with SF-36 total score（r =0.739,P 〈0.01）.The seven factors obtained from factor analysis were basically consistent with the original theoreti-cal conception about SHMS V1.0.Confirmatory factor analysis said,χ2 =2330.101（P =0.000）,CMIN/DF=4.524, GFI=0.855,NFI=0.846,CFI=0.875,AGFI=0.832,RMSEA=0.061,indicating that the model fit were satisfacto-ry.Conclusion：SHMS V1.0 is a reliable and valid measurement scale for evaluating sub-health of town dweller in Guangzhou.
