本研究的目的是评估Hodkinson的简明智力测验(AMT)在痴呆筛查中的有效性，并确定在患病率调查中使用的最佳截断点。这项研究包括两组人：(I)从人口普查数据中随机抽取183人，其中96人完成了研究；(Ii)通过连续抽样从医院门诊部挑选了另外36名痴呆症患者。DSM-IV标准被用作确定痴呆症诊断的‘金标准’。132名参与者接受了AMT，随后他们接受了独立的临床评估。在社区样本中，11人被诊断为痴呆症，85人未被诊断为痴呆症。在总样本中，分数为7表示测试效果最大化。该临界点的灵敏度为91.5%(78.7-97.2%)，特异度为82.4%(72.2-89.5%)。9分给出100%的敏感性，但假阳性的比例上升到66%。我们的结果与其他研究一致，并表明AMT是一种有效的工具，用于在类似于本研究的人群中筛查痴呆症。
The objective of this research was to evaluate the validity of Hodkinson's Abbreviated Mental Test (AMT) in screening for dementia and to identify the optimum cut-off point to use in a prevalence survey. The study included two groups of persons: (i) a random sample of 183 individuals selected from census data, 96 of whom completed the study and (ii) another 36 persons with dementia were selected from a hospital outpatients department by sampling consecutive cases. The DSM-IV criteria were used as the 'gold standard' to establish a diagnosis of dementia. The AMT was administered to the 132 participants who subsequently underwent independent clinical evaluation. In the community sample, 11 persons were diagnosed with dementia and 85 without. In the total sample, a score of 7 maximizes the efficacy of the test. The sensitivity for this cut-off point is 91.5% (78.7-97.2%) and the specificity is 82.4% (72.2-89.5%). A score of 9 gives 100% sensitivity, but the proportion of false positives rises to 66%. Our results are consistent with other studies and Suggest that the AMT is a valid instrument for use in screening for dementia in populations similar to the one in this study.
