| Abstract: |
| 目的对中文版阿尔茨海默病(AD)生命质量量表(QOL-AD)进行项目功能分析, 以确定QOL.AD是否适用于中国大陆AD患者。方法采用分层整群抽样抽取200例AD患者；生命质量测量采用中文版QOL.AD；利用Multilog 7.03软件进行项目功能分析, 得出QOL-AD各条目的>区分度a, 难度系数b, 并确定项目特征曲线(ICC)。结果除了第1条和第7条项目的区分度<0.6外, 其余均>0.6；除了第1条和第7条项目的ICC形态不甚理想, 其他均为第-条和第四条曲线呈单调，而中间两条则呈先升后降的趋势, 并且坡度较陡。结论QOL-AD的项目功能良好, 基本适用中国大陆AD患者。 |

| Objective To introduce the Item Function Analysis(IFA)of Quality of Life-Alzheimer's disease(QOL.AD)Chinese version and to explore the feasibility of its application on Chinese patients with AD.MethodsTwo hundred AD patients were interviewed and assessed by QOL-AD.through the stratified cluster sampling method.Multilog 7.03.was used for Item Function Analysis.Difference scale(a), difliculty scale(b)and Item Characteristic Curve(ICC)of each item of QOL.AD were provided.ResultsDifferent scales of the item 1, 7 were below 0.6, while all the others weYe above 0.6.As for ICC.The first and last lines for the other items were monotonic in which the two in between were in inverted V-shape, with very steep slopes, except for the item 1 and 7.ConclusionResults form the IFA showed that QOL-AD was applicable to be used in the Chinese patients with AD． |
