“短期认知表现测试”（Syndrom Kurztest，SKT）是一种旨在检测记忆和注意力缺陷的认知筛查组合。本研究的目的是评估SKT作为轻度认知功能障碍（MCI）和痴呆的筛查工具的诊断准确性。共有46名阿尔茨海默病（AD）患者，82名MCI患者和56名健康对照者被纳入研究。患者和对照组根据教育水平（8年）分为两组< 8 years or >。ROC分析表明，SKT充分区分AD从非痴呆受试者（MCI和控制），无论教育组。该测试有良好的灵敏度区分MCI从未受损的控制在子样本的个人超过8年的教育。我们的研究结果表明，SKT是一个很好的认知障碍和痴呆症的筛查测试。然而，测试结果必须谨慎解释时，管理教育程度较低的个人。
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 (< 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.
