Abstract- The Cognitive Abilities Screening Instrument (CASI) has been commonly used in dementia research and clinical practice to evaluate a subject's cognitive abilities and to follow-up possible progression of dementia. It has a detailed manual for test administration and scoring in order to minimize testing errors. The Chinese version of CASI (CASI C-2.0) has been used in many clinical and epidemiological studies in Taiwan. Since cognitive abilities are influenced by education, and there are high rates of illiterate or low education individuals among the elderly in Taiwan, the normative data of CASI, including its total score and its cognitive domain scores, should be divided into different education ranges. In clinical practice, the cut-off scores in differentiating between dementia and normal are suggested to be: 49/50 for Education year = 0; 67/68 for Education years = 1-5; and 79/80 for Education years more than 6.
摘要 - 认知能力筛查工具（CASI）已在痴呆症研究和临床实践中广泛用于评估受试者的认知能力，并跟踪痴呆症可能的进展情况。它有详细的测试实施和评分手册，以尽量减少测试误差。CASI中文版（CASI C - 2.0）已在台湾的许多临床和流行病学研究中使用。由于认知能力受教育程度影响，且台湾老年人中文盲或低学历人群比例较高，因此CASI的常模数据，包括其总分和认知领域得分，应按不同教育程度范围划分。在临床实践中，区分痴呆症与正常情况的截断分数建议为：教育年限 = 0时为49/50；教育年限 = 1 - 5时为67/68；教育年限超过6时为79/80。
