This study aimed to explore the threshold of self-rating AD8 in mild cognitive impairment (MCI) and dementia screening among community-dwelling older adults with and without education. 523 participants in Chengdu, China, were recruited: 346 with normal cognitive function, 160 with MCI and 17 with dementia. At the cut-off score of 2, the area under the receiver operator characteristic curves (AUC) of self-rating AD8 for MCI and dementia screening was 0.607 and 0.931 regardless of educational level, respectively. Grouping by educational level, the cut-off in MCI screening was 1 for literate (AUC=0.662) and 2 for illiterate individuals (AUC=0.588). For dementia screening, the cut-off was 2 for illiterate (AUC=0.912) and 4 for literate individuals (AUC=0.963). We concluded that the self-rating AD8 was ideal for dementia screening in community-dwelling older adults, with a cut-off score of 2 for illiterate and 4 for literate people, while its effectiveness for MCI screening required further evaluation.
本研究旨在探讨社区居住的伴有或不伴有教育背景的老年人轻度认知障碍（MCI）和痴呆筛查中自评分 AD8 的截断值。在中国成都招募了 523 名参与者：346 名认知功能正常，160 名 MCI，17 名痴呆。在自评分 AD8 的截断值为 2 时，对于 MCI 和痴呆筛查，受者操作特征曲线（ROC）下面积（AUC）分别为 0.607 和 0.931，无论教育程度如何。按教育程度分组，在 MCI 筛查中，文化程度高者的截断值为 1（AUC=0.662），文化程度低者的截断值为 2（AUC=0.588）。对于痴呆筛查，文盲的截断值为 2（AUC=0.912），文化程度高者的截断值为 4（AUC=0.963）。我们得出结论，自评分 AD8 是社区居住的老年人痴呆筛查的理想工具，文盲的截断值为 2，文化程度高者的截断值为 4，而其对 MCI 筛查的有效性需要进一步评估。
