The Addenbrooke's Cognitive Examination III is one of the most widely used tests to assess cognitive impairment. Although previous studies have shown adequate levels of diagnostic utility to detect severe impairment, it has not shown sensitivity to detect mild decline. The aim of this study was to evaluate the psychometric properties of Addenbrooke's Cognitive Examination III in a large sample of elderly people through Item Response Theory, due to the lack of studies using this approach. A cross-sectional study was conducted with 1164 people from the age of 60 upwards, of which 63 had a prior diagnosis of Alzheimer dementia. The results showed that, globally, the Addenbrooke's Cognitive Examination III possesses adequate psychometrics properties. Furthermore, the information function test shows that the subscales have different sensitivity to different levels of impairment. These results can contribute to determining patterns of cognitive deterioration for the adequate detection of different levels of dementia. An optimized version is suggested which may be an economic alternative in the applied field.
《阿登布鲁克认知测验 III》是评估认知障碍最广泛使用的测试之一。尽管先前的研究表明其具有足够的诊断效用来检测严重损伤，但它对检测轻度下降却没有敏感性。本研究旨在通过项目反应理论评估《阿登布鲁克认知测验 III》在大量老年人样本中的心理测量特性，因为缺乏使用这种方法的研究。进行了一项横断面研究，共有 1164 名年龄在 60 岁以上的人参与，其中 63 人有阿尔茨海默病的先前诊断。结果表明，总体而言，《阿登布鲁克认知测验 III》具有足够的心理测量特性。此外，信息函数测试表明，分量表对不同程度的损伤具有不同的敏感性。这些结果有助于确定认知恶化模式，以便对不同程度的痴呆症进行适当检测。建议使用优化版本，这可能是应用领域的一种经济替代方案。
