PURPOSE –: The purpose of this paper is to examine the reliability and validity of the Abbreviated Mental Test (AMT) and the agreement with the Mini-Mental State Examination (MMSE).
DESIGN/METHODOLOGY/APPROACH –: This cross-sectional study included 446 older adults who were recruited by cluster sampling from 200,481 adults aged more than 60 years. For each participant, the AMT was administered by village health volunteers and, on a separate day, by a trained professional who also administered the MMSE. Descriptive statistics, Bland and Altman levels of agreement, and Receiver Operator Curves (ROCs) were used to analyze data.
FINDINGS –: Administration of the AMT by village health volunteers during the annual health screening found cognitive impairment in only 1.12% of the sample. When the AMT was given to these same individuals by trained professionals, the rate of cognitive impairment was almost 24 times greater. Two items in the Thai AMT may require modification due to markedly elevated failure rates. At the cut score of 8, the sensitivity and specificity of the AMT relative to the MMSE were moderate (78.83 and 66.67%, respectively). The degree of agreement between AMT and MMSE was 0.49 ( < 0.001) and the correlation between the difference scores and the mean is exceptionally low (0.048).
ORIGINALITY/VALUE –: Reliable and valid cognitive screening assessment requires the administrator to be well trained and the tools to be appropriate for the population. Although AMT is short and easy for a nonprofessional to administer, some items were not suitable due to construct validity and contextual issues.
本文旨在检验简易精神状态检查表（AMT）的信度和效度，以及其与简易精神状态检查量表（MMSE）的一致性。
设计/方法/途径：这项横断面研究纳入了446名老年人，他们是从200481名60岁以上成年人中通过整群抽样招募而来。对于每位参与者，由乡村卫生志愿者进行AMT测试，在另一天，由一名经过培训的专业人员进行测试，该专业人员同时也进行MMSE测试。采用描述性统计、布兰德和奥特曼一致性水平以及受试者工作特征曲线（ROC）来分析数据。
在年度健康筛查期间，由乡村卫生志愿者进行AMT测试时，样本中只有1.12%的人被发现有认知障碍。当由经过培训的专业人员对这些相同个体进行AMT测试时，认知障碍率几乎高出24倍。泰国版AMT中的两个项目可能需要修改，因为其失败率明显升高。在8分的临界值时，AMT相对于MMSE的敏感性和特异性中等（分别为78.83%和66.67%）。AMT与MMSE之间的一致性程度为0.49（<0.001），差异分数与均值之间的相关性极低（0.048）。
原创性/价值：可靠且有效的认知筛查评估要求实施者训练有素，工具适合目标人群。尽管AMT简短且非专业人员易于实施，但由于结构效度和背景问题，一些项目并不合适。
