目的 评估SF-12生命质量量表用于评价流动人口生命质量时的信度和效度。方法 采用内部一致性信度评估SF-12生命质量量表的信度,采用集合效度、区分效度和结构效度评估SF-12量表的效度。结果 SF-12生命质量量表用于评价流动人口生命质量时的内部一致性信度cronbach'sα=0.84,各维度与总分的相关系数除了躯体活动功能(PF)=0.43,其余均>0.50;各维度的Cranach'sα系数均>0.70,且在删除相应维度后的Cronbach'sα系数均>0.70;8个维度的集合效度定标实验成功率均为100%,区分效度定标实验成功率均为100%;对量表的理论结构模型进行验证性因子分析,所得模型结构与原始假定一致,拟合指标结果为不规范拟合指数(NNFI)=0.95、比较拟合指数(CFI)=0.96、调整后的拟合优度指数(AGFI)=0.96、近似误差均方根(RMSEA)=0.06。结论 SF-12生命质量量表用于评价流动人口生命质量时具有较好的信度和效度。

Reliability and validity of SF-12 among floating population

Objective To assess the reliability and validity of SF-12 among floating population.Methods The reliability of the SF-12 was assessed by internal consistency reliability and the validity of SF-12 was evaluated by discriminate validity,convergent validity and structural validity.Results The internal consistency reliability Cronbach's was 0.84.The correlation coefficients between each dmiension and total grade were more than 0.50 except physical functioning (0.43).The Cronbach indexes of all dimensions were more than 0.0,and the Cronbach indexes after de-leting corresponding dmiension were more than 0.70.Convergent validity expermient rate and discrmiinate validity expermient rate were 100%.There sults of confirmatory factor analysis showed that the structure of the constructed model was in accord with the theoretical as sumption with a non-normed fitindex (NNFI) of 0.95,a comparative fit index (CFI) of 0.96,an adjusted goodness of fit index (AGFI) of 0.96,and root mean square error of approxmiation(RMSEA) of 0.06.Conclusion The SF-12 for life quality evaluation among floating population has good reliability and validity.
