摘要
[目的]评估SF-12量表用于评价全髋关节置换术后患者生存质量的适用性。[方法]Harris髋关节功能评分量表(Harris hip score,HHS)、SF-12生存质量量表(MOS 12-item Short Form Health Survey,SF-12)评估接受全髋关节置换术治疗的患者283例381髋,采用内部一致性信度(Cronbach's alpha系数)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;Pearson相关分析评估HHS与生理总分、心理总分关联度;单因素方差分析评估生理及心理总分分级的组间差异性。[结果]SF-12量表总的Cronbach's alpha系数为0.879,各维度Cronbach's alpha系数均>0.8;集合效度及区分效度定标实验均为100%;结构效度因子分析产生两个公因子生理及心理总分,累积解释72.229%的总方差,8个维度因子负荷与理论假设基本符合;HHS与生理总分、心理总分均为强相关(r1=0.745,r2=0.703,P<0.01);组间差异F1=85.282,F2=61.377,P<0.01。[结论]SF-12量表具有良好的信度和效度,适用于评价全髋关节置换术后患者的生存质量,评估效果良好。
[Objective]To access the applicability of the SF-12 health survey on measuring quality of life in patients who underwent total hip arthroplasy（THA）.[Methods]Totally 283 patients were measured by Chinese-version 12-item short-form health survey（SF-12） and Harris hip score（HHS）.Reliability of the SF-12 was evaluated by internal consistency reliability.Validity of the SF-12 was evaluated by discriminant validity,convergent validity and structure validity.Pearson correlation coefficient was used to evaluate the correlation of HHS with physical component summary（PCS） and mental component summary（MCS）.One-way analysis of variance（ANOVA） was used to analyze the variance of PCS grading and MCS grading.[Results]The internal consistency Cronbach＇s alpha coefficient was 0.879.The Cronbach＇s alpha of all dimensions were more than 0.8.Convergent validity was 100% and discriminant validity was 100%.Factor analysis revealed two principal components,physical factor and mental factor,explaining 72.229% of the total variance.The constructed structure model was in accord with the theoretical assumption.Correlation between HHS and the two summary scores were respectively positive（r= 0.745 for PCS,r=0.703 for MCS,P0.01）.ANOVA revealed significant deviation of the summary score grades（F=85.282 for PCS,F=61.337 for MCS,P0.01）.[Conclusion]The study indicated that the SF-12 is a useful scale to evaluate the quality of life in the patients who underwent THA.
