Background/Aims: The ABC Dementia Scale (ABC-DS), a new tool for evaluating dementia, was developed in Japan. The ABC-DS is a comprehensive instrument that can simultaneously evaluate activities of daily living (ADLs), behavioral and psychological symptoms of dementia (BPSD), and cognitive function. The ABC-DS can be administered easily and quickly and can clarify the severity of dementia and its changes over time. While the ABC-DS has been reported to be useful in Alzheimer disease (AD)-type dementia, it has not yet been studied in other types of dementia. The purpose of this study was to reevaluate the standard validity of ABC-DS separately for various dementia types and severities. Methods: We evaluated the ABC-DS in outpatients at 1 hospital in Nagasaki Prefecture and patients who use the facility. Domain A, corresponding to ADLs, correlated with Disability Assessment for Dementia (DAD); domain B, corresponding to BPSD, correlated with the Neuropsychiatric Inventory (NPI); domain C, corresponding to cognitive functions, correlated with Mini-Mental State Examination (MMSE); and the total score of the ABC-DS correlated with the Clinical Dementia Rating (CDR). Results: 102 patients, comprising 38 males and 64 females with an average age of 80.7 ± 8.6 years, were enrolled. AD-type dementia was present in 38 cases, vascular dementia (VaD) in 23, mixed dementia in 23, dementia with Lewy bodies in 6, argyrophilic grain dementia in 9, and mild cognitive impairment in 3. A strong correlation was found between ABC-DS domain scores and their respective reference neuropsychological instruments (domain A and the DAD, domain B and the NPI, domain C and the MMSE, and total score and CDR). The correlation of each ABC-DS domain score with the corresponding standard scale depended on the type and severity of dementia, and we observed moderate or high correlations in AD and VaD patients with moderate and severe dementia. Discussion: Although the ABC-DS targets AD, it can be used in VaD based on the results of this study. In other types of dementia, the results differed depending on the domain; in some conditions, the ABC-DS may not show sufficient concurrent validity with other standard scales. Also, the ABC-DS is more beneficial for moderate-to-severe dementia, as reported in previous studies. It is highly useful in clinical practice in Japan since there more than half of all patients have moderate-to-severe dementia.

ABC 痴呆量表与其他标准量表的同时效度：日本评估痴呆症的新综合工具

背景/目的： ABC 痴呆量表 (ABC-DS) 是一种评估痴呆的新工具，是在日本开发的。ABC-DS 是一种综合性工具，可以同时评估日常生活活动 (ADL)、痴呆症的行为和心理症状 (BPSD) 以及认知功能。ABC-DS 可以轻松快速地进行管理，并且可以阐明痴呆症的严重程度及其随时间的变化。虽然据报道 ABC-DS 可用于治疗阿尔茨海默病 (AD) 型痴呆，但尚未在其他类型的痴呆中进行研究。本研究的目的是分别重新评估 ABC-DS 对各种痴呆类型和严重程度的标准有效性。方法：我们在长崎县 1 家医院的门诊患者和使用该设施的患者中评估了 ABC-DS。域 A，对应于 ADL，与痴呆症残疾评估 (DAD) 相关；域 B，对应于 BPSD，与神经精神量表 (NPI) 相关；域 C，对应于认知功能，与简易精神状态检查 (MMSE) 相关；ABC-DS 的总分与临床痴呆评分 (CDR) 相关。结果：入组患者102例，男38例，女64例，平均年龄80.7±8.6岁。AD型痴呆38例，血管性痴呆（VaD）23例，混合型痴呆23例，路易体痴呆6例，嗜银颗粒性痴呆9例，轻度认知障碍3例。 -DS 域得分及其各自的参考神经心理学工具（域 A 和 DAD、域 B 和 NPI、域 C 和 MMSE，以及总分和 CDR）。每个 ABC-DS 域评分与相应标准量表的相关性取决于痴呆的类型和严重程度，我们在 AD 和 VaD 中度和重度痴呆患者中观察到中度或高度相关性。讨论：尽管 ABC-DS 以 AD 为目标，但根据本研究的结果，它可以用于 VaD。在其他类型的痴呆症中，结果因领域而异；在某些情况下，ABC-DS 可能无法与其他标准量表同时显示出足够的效度。此外，如先前研究报告的那样，ABC-DS 对中度至重度痴呆症更有益。它在日本的临床实践中非常有用，因为超过一半的患者患有中度至重度痴呆症。
