摘 要:目的分析SF-12量表用于评价城市建筑业农民工人群生存质量的信度和效度。方法采用内部一致性信度评估SF-12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量表评价城市建筑业农民工人群的内部一致性信度Cronbach’sα系数为0.776,8个维度的集合效度定标试验成功率为100%,区分效度定标试验成功率为100%;对量表的理论模型进行验证性因子分析,所得模型与原始假定一致,拟合指标结果为RMSEA=0.052,NFI=0.973,CFI=0.982,AGFI=0.964。结论 SF-12量表适用于城市建筑业农民工群体的生存质量评价。Objective To access the reliability and validity of the 12- Item Short- Form Health Survey( SF- 12) applied in assessing the quality of life of rural migrants working in construction sites in cities. Methods Reliability of the SF- 12 was evaluated by internal consistency reliability,and validity was evaluated by convergent validity,discriminant validity and structure validity. Results The internal consistency,indicated by Cronbach's α coefficient,was 0. 776. The success rates of convergent validity experiments and discriminant validity experiments of 8 dimensions were all 100%. The structure validity test by confirmatory factor analysis indicated that the model was consistent with the theoretical assumption,and the fitness indexes were RMSEA = 0.052,NFI = 0. 973,CFI = 0. 982,and AGFI = 0. 964. Conclusions SF- 12 is applicable for assessing the quality of life of rural migrants working in construction sites in cities.
