Abstract

Objective: The psychometric rigor of unsupervised, smartphone-based assessments and factors that impact remote protocol engagement is critical to evaluate prior to the use of such methods in clinical contexts. We evaluated the validity of a high-frequency, smartphone-based cognitive assessment protocol, including examining convergence and divergence with standard cognitive tests, and investigating factors that may impact adherence and performance (i.e., time of day and anticipated receipt of feedback vs. no feedback).

Methods: Cognitively unimpaired participants (N = 120, Mage = 68.8, 68.3% female, 87% White, Meducation = 16.5 years) completed 8 consecutive days of the Mobile Monitoring of Cognitive Change (M2C2), a mobile app-based testing platform, with brief morning, afternoon, and evening sessions. Tasks included measures of working memory, processing speed, and episodic memory. Traditional neuropsychological assessments included measures from the Preclinical Alzheimer's Cognitive Composite battery.

Results: Findings showed overall high compliance (89.3%) across M2C2 sessions. Average compliance by time of day ranged from 90.2% for morning sessions, to 77.9% for afternoon sessions, and 84.4% for evening sessions. There was evidence of faster reaction time and among participants who expected to receive performance feedback. We observed excellent convergent and divergent validity in our comparison of M2C2 tasks and traditional neuropsychological assessments.

Conclusions: This study supports the validity and reliability of self-administered, high-frequency cognitive assessment via smartphones in older adults. Insights into factors affecting adherence, performance, and protocol implementation are discussed.

高频率、基于智能手机的老年人认知筛查方案的心理测量和坚持性考虑因素。
目的:在临床环境中使用无监督、基于智能手机的评估方法之前,对其心理测量的严谨性以及影响远程方案参与的因素进行评估至关重要。我们评估了基于智能手机的高频认知评估方案的有效性,包括检查与标准认知测试的趋同性和差异性,并调查可能影响坚持性和表现的因素(即一天中的时间和预期收到反馈与没有反馈):认知能力未受损的参与者(人数 = 120,年龄 = 68.8,68.3% 为女性,87% 为白人,教育程度 = 16.5 岁)连续 8 天完成了基于移动应用程序的测试平台 "认知变化移动监测"(M2C2)的上午、下午和晚上的简短测试。任务包括测量工作记忆、处理速度和外显记忆。传统的神经心理学评估包括临床前阿尔茨海默氏症认知综合测试:研究结果表明,M2C2 课程的总体依从性较高(89.3%)。不同时间段的平均依从性从上午课程的 90.2% 到下午课程的 77.9% 以及晚上课程的 84.4% 不等。有证据表明,预期会收到成绩反馈的参与者的反应时间更快。在对 M2C2 任务和传统神经心理学评估的比较中,我们观察到了极好的收敛有效性和发散有效性:本研究支持通过智能手机对老年人进行自我管理的高频认知评估的有效性和可靠性。本研究还讨论了影响依从性、表现和方案实施的因素。

期刊介绍: The Journal of the International Neuropsychological Society is the official journal of the International Neuropsychological Society, an organization of over 4,500 international members from a variety of disciplines. The Journal of the International Neuropsychological Society welcomes original, creative, high quality research papers covering all areas of neuropsychology. The focus of articles may be primarily experimental, applied, or clinical. Contributions will broadly reflect the interest of all areas of neuropsychology, including but not limited to: development of cognitive processes, brain-behavior relationships, adult and pediatric neuropsychology, neurobehavioral syndromes (such as aphasia or apraxia), and the interfaces of neuropsychology with related areas such as behavioral neurology, neuropsychiatry, genetics, and cognitive neuroscience. Papers that utilize behavioral, neuroimaging, and electrophysiological measures are appropriate. To assure maximum flexibility and to promote diverse mechanisms of scholarly communication, the following formats are available in addition to a Regular Research Article: Brief Communication is a shorter research article; Rapid Communication is intended for "fast breaking" new work that does not yet justify a full length article and is placed on a fast review track; Case Report is a theoretically important and unique case study; Critical Review and Short Review are thoughtful considerations of topics of importance to neuropsychology and include meta-analyses; Dialogue provides a forum for publishing two distinct positions on controversial issues in a point-counterpoint format; Special Issue and Special Section consist of several articles linked thematically; Letter to the Editor responds to recent articles published in the Journal of the International Neuropsychological Society; and Book Review, which is considered but is no longer solicited.
