世界卫生组织残疾人生存质量量表一般残疾版本中文版的信效度

摘要

目的:检验世界卫生组织残疾人生存质量量表一般残疾版本(WHOQOL-DIS Scales for PD)中文版的可接受性、信度和效度,以便用于中国残疾人的生存质量的研究.方法:采用多阶段分层随机抽样的方法,从广州市抽取一般残疾人(除智力残疾的其他残疾人)807名.间隔1周后,对自愿进行重复调查的109人进行重测.对量表进行可接受性、信度和效度检验,并以生活满意度量表(SWLS)为校标.结果:量表回收率为99.2％,除了性生活满意度条目缺失率为35.7％,其余条目的缺失率均小于5.0％.量表5个领域的Cronbach α系数为0.77 ～0.84;间隔1周后重测ICC为0.82 ～0.91.量表条目与所属领域得分的秩相关系数为0.30 ～0.84,高于与其他领域的相关性;验证性因子分析显示量表的拟合较好(x2=2405.57,df=569,RMSEA=0.06,GFI=0.85,CFI=0.87);量表5个领域得分与SWLS得分呈正相关(r=0.15～0.45,均P＜0.05).结论:世界卫生组织残疾人生存质量量表一般残疾版本中文版具有较好的可接受性、信度和效度,可用于中国残疾人生存质量的研究.%Objective: To examine the acceptability, reliability and validity of the Chinese version of World Health Organization Quality of Life-Disability Scales for physical disability (WHOQOL-DIS Scales for PD) for the study of quality of life of Chinese with disability. Methods: A sample of 807 persons with physical disability (per-sons with disability except for those with intellectual disability) in Guangzhou was recruited through multi-stage sampling method, 109 of them were volunteered to be retested one week later. The scales were accessed with accessibility and reliability as well as validity. Also the Satisfaction with Life Scale was used as the criteria to exam the criteria validity. Results: The response rate of WHOQOL-DIS Scales for PD was 99. 2% , missing item rate was less than 5. 0% except for the item about sexual life with missing rate equaling 35. 7%. The Cronbach a coefficient of 5 subscales was between 0. 77 - 0. 84, and the intraclass correlation coefficient ranged from 0. 82 to 0. 91 after the one-week later retest of the scales. And each item was correlated with its subscales with rank correlation coefficient equaling 0. 30 - 0. 84, which was higher than those with other subscales. Confirmatory factor analysis showed good fitness of the scales. The scores of domains of the WHOQOL-DIS Scales were positively correlative with that of the Satisfaction with Life Scale, and the correlation coefficient ranged from 0. 15 to 0. 45. Conclusions: The results support that the Chinese Version of World Health Organization Quality of Life-Disability Scales for physical disability was acceptable, reliable and valid and could be used in the study of quality of life in Chinese subjects with disability.
