目的评价SF-36生活质量量表用于测量新疆图瓦成人生活质量的信度和效度。方法采用多阶段抽样的方法,于2016年在新疆阿勒泰地区哈巴河县白哈巴村和布尔津县喀纳斯、禾木村,随机抽取了437名图瓦成年人作为调查对象(男性227人,女性210人;18～29岁占30.66%、30～49岁占54.00%、≥50岁占15.33%)。使用SF-36量表评价生命质量,用内部一致性信度和折半信度评价量表信度;采用集合效度、区分效度和结构效度评价量表的效度。结果 SF-36量表的Cronbach’α系数为0.838,删除相应维度后的Cronbach’α系数均>0.750。Spearman-Brown系数为0.828。集合、区分效度定标试验成功率分别为100%和99.59%。将35个条目纳入探索性因子分析,用最大平衡化旋转法提取7个公因子,累计贡献率为68.97%。将8维度纳入探索性因子分析,提取2个公因子,累计贡献率为66.44%。验证性因子分析模型拟合结果不理想。结论 SF-36量表用于评价新疆图瓦成年人生活质量有良好的信度、集合与区分效度,结构效度有待提高。

OBJECTIVE To assess the reliability and validity of SF-36 scale in measuring quality of life of Tuva adults in Xinjiang Uygur Autonomous Region. METHODS A total of 437 Tuva adults were selected by multistage sampling method, in Tuva families lived in Baihaba Village Habahe county and Kanasi and Hemu Villages Buerjin County in Artay Xinjiang Uygur Autonomous Region in 2016,including 100 males and 50 females, the three age groups 18-29, 30-49, 50 and above accounted for 30.66%, 54.00% and 15.33% respectively. SF-36 scale was be used to measure the quality of life. The scale's reliability was assessed by internal consistency reliability and half-fold reliability, and the validity was assessed by set validity,discriminate validity and structural validity. RESULTS The Cronbach's α coefficient of the SF-36 scale was 0.838,and all of the Cronbach's α coefficients were more than 0.750 after corresponding dimensions were deleted. The Spearman-Brown coefficient was 0.828. The achievement ratio of aggregation tests and discrimination tests were 100% and 99.59%,respectively. Thirty-five items were included in EFA. Seven common factors were extracted through maximum balanced rotation method, and the cumulative contribution rate was 68.97%. Eight-dimensional data were included in EFA, and two common factors were extracted with a cumulative contribution rate of 66.44%. The fitting degree of confirmatory factor analysis model is invalid. CONCLUSION SF-36 has showed a good reliability, set validity and discrimination validity in evaluating the quality of life of Tuva adults in Xinjiang, but its structural validity needs to be improved.
