The Brief Cognitive Assessment Tool (BCAT) is a new screening measure for cognitive dysfunction that emphasizes contextual memory and executive control functions. A total of 104 older adults referred for neuropsychological evaluation were recruited from assisted-living facilities. Psychometric analyses confirmed strong evidence for reliability, construct validity, and predictive validity. The BCAT's utility for identifying dementia versus mild cognitive impairment was excellent, with a sensitivity of .99, a specificity of .77, and an area under the receiver-operating characteristic (ROC) curve of .95. Executive control, contextual memory, and attentional capacity items were the best predictors of diagnostic category and of instrumental activities of daily living.
简易认知评估工具（BCAT）是一种新的认知功能障碍筛查工具，强调情景记忆和执行控制功能。共有 104 名来自辅助生活设施的老年人被招募进行神经心理评估。心理测量学分析证实了该工具具有可靠性、结构有效性和预测有效性的有力证据。BCAT 在识别痴呆症与轻度认知障碍方面具有优异的效用，其敏感性为 0.99，特异性为 0.77，受试者工作特征（ROC）曲线下面积为 0.95。执行控制、情景记忆和注意力容量项目是诊断类别和工具性日常生活活动的最佳预测指标。
