SF-36量表在糖尿病和糖耐量减低患者生命质量研究中的信度、敏感性和可行性评价

Evaluation on reliability,sensitivity and feasibility of SF-36 instrument with the quality of life in DM and IGT

目的 :评价SF -36量表在我国糖尿病(DM)和糖耐量低减(IGT)患者生命质量研究中的信度、敏感性和可行性。方法 :通过对DM、IGT患者和糖耐量正常者(NGT)使用SF -36量表的生命质量(QualityofLifeQL)自评数据进行评价。结果 :DM和IGT的劈半信度分别为0.93和0.84 ;总量表的Cronbach'sα系数、θ系数和Ω系数均>0.9 ,分量表的8个维度除了精力分项(最低为0.57)外 ,其余各维度的三系数(至少有一项)均达到一般认可的标准以上 ;QL各维度评分的大多数(18/24)和综合评分为DM<IGT<NGT,且某些维度和综合评分的差异显著(P<0.05) ;研究对象对量表的接受率和完成率均为100 % ,完成时间平均5min。结论 :SF -36量表信度良好 ,敏感性可 ,可行性好 ,适合应用于我国DM和IGT患者QL的研究。

Objective:To evaluate the reliability,sensitivity and feasibility of SF-36 instrument with the quality of life in DM and IGT.Methods:With the self assessed data of quality of life in subjects with DM,IGT and NGT from a prevalence study,the reliability,sensitivity and feasibility of SF-36 instrument have been evaluated.Results:In patients with DM and IGT,the spilt half reliability was 0.93 and 0.84 respectively,cronbach's αcoefficient,theta(θ) coefficient and omegea(Ω) coefficient of SF-36 instrument was over 0.9,the SF-36 instrument including eight multitem dimemsions,except in vitality(the lowest was 0.57),the three coefficients(at least one of them)attained or exceed the accepatable criterion(≥0.8 is excellent,≥0.7 is good).Most of mean(18/24) score of quality of life in dimensions and instrument was the lowest in DM and the highest in NGT,mean score of four dimensions and the instrument in DM was apparently differenct with in NGT(P< 0.05),while compared in DM and in IGT,mean score of two dimensions was apparently different,the acceptable and completed rate was 100 percent,the average completed time was 5 minutes.Conclusion :The reliability,sensitivity of SF-36 instrument are excellent,it's feasibility is satisfying.the SF-36 is a suitable instrument in DM and IGT in China.
