OBJECTIVE: The objective was to adapt and validate Addenbrooke\'s Cognitive Examination-III (ACE-III) for screening general cognitive functions in illiterate and low-literate older populations in the Indian context in three languages.
METHODS: The Indian illiterate ACE-III was systematically adapted by modifying the original items of the Indian literate ACE-III to assess the cognitive functions of illiterates and low-literates with the consensus of an expert panel of professionals working in the area of dementia and related disorders. A total of 180 illiterate or low-literate participants (84 healthy-controls, 50 with dementia, and 46 with mild cognitive impairment [MCI]) were recruited from three different centers speaking Bengali, Hindi, and Kannada to validate the adapted version.
RESULTS: The optimal cut-off score for illiterate ACE-III to distinguish controls from dementia in all 3 languages was 75. The optimal cut-off scores in distinguishing between controls and MCI ranged from 79 to 82, with a sensitivity ranging from 93% to 99% and a specificity ranging from 72% to 99%.
CONCLUSIONS: The test is found to have good psychometric properties and is a reliable cognitive screening tool for identifying dementia and MCI in older adults with low educational backgrounds in the Indian context.
目的:目的是适应和验证Addenbrooke的认知检查-III(ACE-III),以筛查印度文盲和低识字老年人群的一般认知功能。三种语言。
方法:通过修改印度文学ACE-III的原始项目来系统地调整印度文盲ACE-III,以评估文盲和低文化人的认知功能,并与在痴呆症和相关疾病领域工作的专家小组达成共识。共有180名文盲或低文化程度的参与者(84名健康对照,50患有痴呆症,和46名轻度认知障碍[MCI])从三个讲孟加拉语的不同中心招募,印地语,和卡纳达语来验证改编版本。
结果:在所有3种语言中,文盲ACE-III区分对照和痴呆的最佳截止分数为75。区分对照和MCI的最佳截止分数为79至82,灵敏度为93%至99%,特异性为72%至99%。
结论:该测试被发现具有良好的心理测量特性,并且是在印度背景下识别低教育背景老年人的痴呆和MCI的可靠认知筛查工具。
