扩充痴呆量表(ESD)在痴呆诊断中的应用

The Application of ESD in the Diagnosis of Dementia

目的 :在健康老人和痴呆病人中应用 ESD进行试测 ,观察修订后的 ESD在中国老年人中应用的有效性。方法 :连续收集痴呆病人 69例 ,测查 4 70名不同学历和年龄的健康老人作量表的信效度检验。结果 :健康人的测查结果表明 ESD分半信度系数达 0 .9,内部一致性系数 0 .69- 0 .78,病人的正确划分率 97%。 ESD得分在轻中重三组病人中明显不同 ,且测验成绩反映的各功能损害程度与变化的状况符合痴呆病情发展的一般特征。但测验成绩在老年性痴呆和血管性痴呆等不同病因组间无明显差别。结论 :ESD测验信效度良好 ,测验成绩与病情密切相关 ,对病情发展变化的观察比较实用 ,可作为全面评价智能状况的工具 ,而对病因鉴别的帮助不大。

Objective:to test the reliability and validity of revised version of Expansive Scale of Dementia in Chinese elderly——healthy or demented.Method:the total sample consisted of 69 demented and 470 healthy elderly with different educational levels.Result:split-reliability derived from healthy elderly was 0 9,inner consistency 0 69-0 78,the rate of correct separation was 97%.The scores of ESD varied with the degree of dementia,cognitive defects reflected by ESD were consistent with the stage of dementia.But there was no difference between vascular dementia and senile dementia.Conclusion:ESD had good reliability and validity, and was practical in clinics.But it can not differentiate different kinds of dementia.
