摘要
处理速度变慢是正常衰老的一部分，但也是包括痴呆症在内的许多疾病的症状。认知速度快速测试(Quick Test of Cognitive Speed, AQT)由三个条件组成:颜色命名(AQT1)、形式命名(AQT2)和双颜色形式命名(AQT3)，提供了一种用户友好的处理速度评估方法，国际上用于识别老年患者的认知障碍。然而，缺乏适当的年龄标准。这项研究提供了来自瑞典158名认知健康的80至94岁老人样本的基于回归的规范。结果显示，在所有三种情况下，年龄都有影响，AQT1存在非线性教育效应，AQT2和AQT3的年龄受性别影响:随着年龄的增长，男性的表现更差，但女性的表现持平。然而，无论年龄和性别，AQT2和AQT3的平均原始分数和预测分数都低于迄今为止推荐的疑似认知障碍的截止标准。
A quick test of cognitive speed (AQT): regression-based norms for cognitively healthy 80 to 94-year olds.
Slowed processing speed is part of normal aging but also a symptom of many diseases, including dementia. A Quick Test of Cognitive Speed (AQT) consists of three conditions: color naming (AQT1), form naming (AQT2) and dual color-form naming (AQT3) and offers a user-friendly assessment of processing speed that is used internationally to identify cognitive impairment in elderly patients. Appropriate age-norms have however been lacking. This study provides regression-based norms derived from a Swedish sample of 158 cognitively healthy 80 to 94-year olds. The results show age effects in all three conditions, a non-linear education effect in AQT1, and age by gender interactions in AQT2 and AQT3: men performed worse with increasing age, but women remained on a par. However, irrespective of age and gender, AQT2 and AQT3 mean raw and predicted scores were slower than the hitherto recommended cutoff criteria for suspected cognitive impairment.
