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.
处理速度缓慢是正常衰老的一部分,但也是许多疾病的症状,包括痴呆症。认知速度快速测验(AQT)由三个条件组成:颜色命名(AQT1)、形状命名(AQT2)和双重颜色-形状命名(AQT3),提供了一种用户友好的处理速度评估方法,该方法在国际上用于识别老年患者的认知障碍。然而,合适的年龄规范一直缺乏。本研究提供了基于从瑞典 158 名认知健康的 80 至 94 岁老年人样本中得出的回归规范。结果表明,所有三种条件都存在年龄效应,AQT1 中的教育效应是非线性的,AQT2 和 AQT3 中的年龄与性别相互作用:男性随着年龄的增长表现越差,但女性则保持一致。然而,无论年龄和性别如何,AQT2 和 AQT3 的原始和预测得分都比迄今推荐的疑似认知障碍的临界值标准慢。
