摘　　要：目的:研制WHOQOL-OLD量表的简化版,并考察该简表的信效度。方法:在WHOQOL-OLD国际合作组提供的5566名老年人样本资料中,随机抽取2/3作为训练样本,1/3为考核样本。用经典测量理论和项目反应理论的方法对训练样本进行条目筛选,并用考核样本评价简表的信度和效度。结果:每个领域保留2个较优的条目,形成了12个条目的简明量表WHOQOL-OLD-12。简表各领域的平均信息量仅减少了22.1%～32.9%;简表的克朗巴赫系数为0.80;各领域与WHOQOL-BREF各领域及总分的相关系数介于0.21～0.76之间,大部分大于0.40。结论:WHOQOL-OLD简明量表具有可接受的信度和效度,是老年人生存质量研究中简单易行的测量工具。Objective：To develop a short form of questionnaire WHOQOL-OLD,and evaluate its reliability and validity.Methods：From a sample of 5566 old adults provided by the research team of WHOQOL-OLD,2/3 of them were randomly selected and used as a training sample,and the remaining 1/3 as a validation sample.The methods of classical test theory and item response theory were used to select the better items in the training sample.And the validation sample was used to evaluate the reliability and validity of the short form scale.Results：2 better items remained within each domain of the original WHOQOL-OLD scale,a short form WHOQOL-OLD-12 was formed.The average amount of t of the six domains of short form scale was reduced from 22.1% to 32.9% only;the Cronbach＇α of the short form was 0.8;and the correlation coefficients between the domains of WHOQOL-OLD-12 and WHOQOL-BREF ranged from 0.21 to 0.76,most of them were greater than 0.4,which showed better criterion validity.Conclusion：With acceptable reliability and validity,WHOQOL-OLD-12 is a refined instrument for the quality of life of older adults.
