The "Short Cognitive Performance Test" (Syndrom Kurztest, SKT) is a cognitive screening battery designed to detect memory and attention deficits. The aim of this study was to evaluate the diagnostic accuracy of the SKT as a screening tool for mild cognitive impairment (MCI) and dementia. A total of 46 patients with Alzheimer's disease (AD), 82 with MCI, and 56 healthy controls were included in the study. Patients and controls were allocated into two groups according to educational level (< or =8 years or >8 years). ROC analyses suggested that the SKT adequately discriminates AD from non-demented subjects (MCI and controls), irrespective of the education group. The test had good sensitivity to discriminate MCI from unimpaired controls in the sub-sample of individuals with more than 8 years of schooling. Our findings suggest that the SKT is a good screening test for cognitive impairment and dementia. However, test results must be interpreted with caution when administered to less-educated individuals.
“简易认知功能测试”（综合征简短测试，SKT）是一种认知筛查组合测试，旨在检测记忆和注意力缺陷。本研究的目的是评估SKT作为轻度认知障碍（MCI）和痴呆症筛查工具的诊断准确性。该研究共纳入了46名阿尔茨海默病（AD）患者、82名MCI患者和56名健康对照者。患者和对照者根据教育水平（≤8年或>8年）分为两组。受试者工作特征（ROC）分析表明，无论教育水平分组如何，SKT都能充分区分AD患者与非痴呆受试者（MCI患者和对照者）。在受教育年限超过8年的个体子样本中，该测试在区分MCI患者与未受损对照者方面具有良好的敏感性。我们的研究结果表明，SKT是一种用于认知障碍和痴呆症的良好筛查测试。然而，对受教育程度较低的个体进行测试时，必须谨慎解释测试结果。
