大学生亚健康评定量表的测评及应用分析

摘要

Objective To assess the structure validity of application of sub-health measurement scale version 1.0(SHMS V1.0)in college students in Guangzhou City to lay a foundation for further analyzing the healthy status in this group and its influen-cing factors.Methods Nine hundreds college students were selected by adopting the stratified random sampling method for conduc-ting the questionnaire survey.The SPSS20.0 and AMOS21.0 were adopted to conduct the exploratory factor analysis(EFA)and confirmatory factor analysis(CFA)respectively.Results EFA obtained 7 factors with eigenvalue more than 1,the cumulative vari-ance contribution rate was 56.766%,moreover 7 factors were basically consistent with the theoretical structure of SHMS V 1.0. CFA conducted the model fitting for 3 total scales and 3 subscales,the results showed that the fitting of 3 subscales was good,the fitting result of total scale could be accepted,but did not reach the desired effect.Therefore,five times modification was applied in the total scale,and the fitting indexes after modification were CMIN/DF=2.723,GFI=0.907,IFI=0.917,TLI= 0.905,CFI=0.917,RMSEA=0.046,the fitting effect was comparatively excellent.Conclusion The dimension division of sub-health measure-ment scale is basically reasonable,and using this scale for measuring the sub-health status of college students in Guangzhou City has a better structure validity.%目的 考评亚健康评定量表(SHMS V1.0)应用于广州市大学生的结构效度,为进一步分析该群体的健康状况及影响因素奠定基础.方法 采用分层随机抽样的方法选取900名广州市大学生进行问卷调查,分别采用SPSS20.0和AMOS21.0进行探索性因子分析(EFA)和验证性因子分析(CFA).结果 EFA 得到7个特征值大于1的因子,累积方差贡献率为56.766%,且7个因子与SHMS V1.0的理论结构基本吻合.CFA对总量表和3个子量表均进行了模型的拟合,结果显示3个子量表的拟合较好,总量表的拟合结果可以接受,但未达到理想效果.对总量表进行了5次修正,修正后总量表的拟合指标为:卡方自由度比值(CMIN/DF)=2.723、拟合优度指数(GFI)=0.907、增值拟合指数(IFI)=0.917、非规范拟合指数(TLI)=0.905、比较拟合指数(CFI)=0.917、近似误差均方根(RMSEA)=0.046,拟合效果较优.结论 亚健康评定量表维度的划分基本合理,使用该量表测量广州市大学生的亚健康状况具有较好的结构效度.
