迫切需要可以远程部署的评估方法，以衡量临床试验和纵向老龄化队列中的认知结果。为此，我们评估了一项基于手机的密集测量研究的效用。一小群健康的老年人(N=17，平均年龄=73)在12个月内完成了5次评估“突发”，每次评估突发包括连续5天每天两次评估。每项评估都包括对视觉短期记忆和信息处理速度的简短测试，以及测量可能影响认知的状态因素的调查。在研究终点，我们有94%的保留率、97%的遵从性和很高的参与者满意度。移动认知测试得分显示出良好的可靠性，与面对面基线神经心理测试的相关性中等，与参与者的年龄和教育水平显著相关。我们的结论是，基于手机的密集测量设计代表了一种很有前途的纵向测量老年人认知的评估方法。
There is a pressing need for assessment approaches that can be deployed remotely to measure cognitive outcomes in clinical trials and longitudinal aging cohorts. We evaluated the utility of a mobile phone-based intensive measurement study for this purpose. A small cohort of healthy older adults (N=17, mean age=73) completed five assessment “bursts” over 12 months, with each measurement burst involving two assessments daily for five consecutive days. Each assessment included brief tests of visual short-term memory and information processing speed, as well as surveys measuring state factors that can affect cognition. At study endpoint we had 94% retention, 97% compliance, and high participant satisfaction. Mobile cognitive test scores demonstrated good reliability, moderate correlations with in-person baseline neuropsychological testing, and significant associations with participant age and education level. We conclude that mobile phone-based intensive measurement designs represent a promising assessment approach for measuring cognition longitudinally in older adults.
