Abstract

Objective: The ability to remotely monitor cognitive skills is increasing with the ubiquity of smartphones. The Mobile Toolbox (MTB) is a new measurement system that includes measures assessing Executive Functioning (EF) and Processing Speed (PS): Arrow Matching, Shape-Color Sorting, and Number-Symbol Match. The purpose of this study was to assess their psychometric properties.

Method: MTB measures were developed for smartphone administration based on constructs measured in the NIH Toolbox® (NIHTB). Psychometric properties of the resulting measures were evaluated in three studies with participants ages 18 to 90. In Study 1 (N = 92), participants completed MTB measures in the lab and were administered both equivalent NIH TB measures and other external measures of similar cognitive constructs. In Study 2 (N = 1,021), participants completed the equivalent NIHTB measures in the lab and then took the MTB measures on their own, remotely. In Study 3 (N = 168), participants completed MTB measures twice remotely, two weeks apart.

Results: All three measures exhibited very high internal consistency and strong test-retest reliability, as well as moderately high correlations with comparable NIHTB tests and moderate correlations with external measures of similar constructs. Phone operating system (iOS vs. Android) had a significant impact on performance for Arrow Matching and Shape-Color Sorting, but no impact on either validity or reliability.

Conclusions: Results support the reliability and convergent validity of MTB EF and PS measures for use across the adult lifespan in remote, self-administered designs.

移动工具箱（MTB）执行功能和处理速度远程测量：开发与验证。

目的：随着智能手机的普及，远程监控认知技能的能力也在不断提高。移动工具箱（MTB）是一种新的测量系统，包括评估执行功能（EF）和处理速度（PS）的测量方法：移动工具箱（MTB）是一个新的测量系统，包括评估执行功能（EF）和处理速度（PS）的测量项目：箭头匹配、形状-颜色分类和数字-符号匹配。本研究旨在评估其心理测量特性：方法：根据美国国立卫生研究院工具箱®（NIHTB）中测量的结构，开发了适用于智能手机的 MTB 测量。在三项针对 18 至 90 岁参与者的研究中，对所产生的测量结果的心理测量特性进行了评估。在研究 1（N = 92）中，参与者在实验室完成了 MTB 测量，并接受了等效的 NIH TB 测量和其他类似认知结构的外部测量。在研究 2（N = 1,021 人）中，参与者在实验室完成等效的 NIHTB 测量，然后自行远程进行 MTB 测量。在研究 3（N = 168）中，参与者两次远程完成 MTB 测量，每次间隔两周：结果：所有三项测量都表现出很高的内部一致性和很强的重测可靠性，与可比的 NIHTB 测试有中等程度的相关性，与类似结构的外部测量有中等程度的相关性。手机操作系统（iOS 与 Android）对箭头匹配和形状-颜色排序的成绩有显著影响，但对效度和信度均无影响：研究结果表明，MTB EF 和 PS 测量具有可靠性和收敛有效性，可在远程自测设计中用于成年人的整个生命周期。
