摘要：

      摘要 目的：建立基于《国际功能、残疾和健康分类》（ICF）理论框架，适用于老年人群，符合中国国情的老年失能评估量表(EDAS)正式版。 方法：采用EDAS初始量表对四川大学华西医院老年病科和四川省成都市跳伞塔社区的170例老人进行调查，对调查结果采用临界比值法、相关系数法、克朗巴赫系数法和因子分析法筛选条目，编制正式量表。 结果：共回收168份有效量表，回收率为98.8%。根据调查结果，计算出6个用于条目筛选的统计量，分别是决断值、条目与总分的相关系数、修正条目的总相关系数（CITC）、条目删除时的克朗巴赫系数、公因子方差和因子负荷量。若有两种或两种以上的统计量同时建议删除某条目，则予以删除。最终共删除4个条目，由剩余条目构成正式量表，包含28个条目，分属“身体功能”和“活动和参与”两个领域的7个维度。 结论：本研究采用EDAS初始量表进行人群调查，采用多种统计学方法筛选条目，编制了EDAS正式量表。

Abstract:

      Abstract Objective：To develop the formal version of Elderly Disability Assessment Scale (EDAS) to assess disability for Chinese older people according to the International Classification of Functioning, Disability and Health (ICF). Method: The preliminary investigation was conducted in the Geriatric Department, West China Hospital of Sichuan University and Tiaosanta community in Chengdu, China. One hundred and seventy older persons were included. Proper items were selected from the preliminary version according to the data using the following statistical methods: critical ration, correlation coefficient method, Cronbach's α, and factor analysis method. Based on these work, the formal version of EDAS was developed. Result: Totally 168, accounting for 98.8%, valid scales were used for data analyses. Using multiple statistical methods listed above, 4 items were deleted. The formal version of EDAS included 28 items, which belonging to two ICF domains i.e. “body function” and “activities and participations” (including 7 dimensions). Conclusion: The formal version of the EDAS was established based on a Chinese older population with a veriety of statistical methods.
