摘要
[目的]评价简明健康状况调查量表(SF-36)应用于老年轻度认知功能障碍(MCI)病人中的信度与效度。[方法]应用SF-36量表,由同一调查员对方便抽样的74例MCI病人进行面对面访谈以调查其健康相关生活质量,采用SPSS软件对测量结果进行信度与效度分析。[结果]SF-36量表8个维度的重测相关系数除RP、BP和VT外均大于0.5(P〈0.01),总量表SpearmanBrown分半信度系数为0.910,内部一致性Cronbach’sα系数除SF和VT为0.6-0.7外,其余各维度及两个总评均大于0.7,整个量表的Cronbach’sα系数为0.890;各维度与总量表的相关系数为0.448-0.813(P〈0.01),除PF、RP和RE外其他各维度间相关系数为0.500-0.828(P〈0.01);因子分析所产生的3个公因子可解释总变异的78.30%,并在相应项目上有较强的因子载荷。[结论]SF-36量表应用于老年MCI病人有较好的信度和效度,适用于评价老年MCI病人的生活质量。
Objective:To evaluate the reliability and validity of SF-36 scale applied for elderly patients with mild cognitive impairment.Methods:A total of 74 MCI patients from convenience sampling received face-to-face interview from the same investigator by using SF-36 scale,so as to investigate their health related quality of life.The reliability and validity of measurement results were analyzed by using SPSS software.Results:The retest correlation coefficient of eight dimensions of SF-36 scale was more than 0.5except RP,BP and VT(P〈0.01);in total Spearman-Brown scale score,half reliability coefficient was 0.910;internal consistency Cronbach'sαcoefficient in SF and VT was 0.6-0.7and it in other six dimensions and two component summary was more than 0.7;Cronbach'sαcoefficient of whole scale was 0.890;correlation coefficient between each dimension and total scale score was 0.448-0.813(P〈0.01);except PF,RP and RE,correlation coefficient among other dimensions was 0.500-0.828(P〈0.01);three common factors produced in factor analysis may explain 78.30%of the total variance,and there was a strong factor loadings in the respective projects.Conclusion:The SF-36 scale applied for elderly MCI patients has better reliability and validity,and it is applicable to evaluate the quality of life of elderly MCI patients.
