ABSTRACT

Inclusion of Black participants in clinical research is a national priority. Mobile applications and remote data collection may increase study access for diverse populations. This study examined the reliability and feasibility of two mobile smartphone application-based cognitive measures in a diverse middle aged and older adult sample. Black (n = 44; M_age = 59.93) and non-Hispanic white (NHW; n = 50; M_age = 61.06) participants completed traditional paper-based neuropsychological testing and two app-based measures, Arrows and Number Match. Intraclass correlations demonstrated poor to moderate reliability (range: .417–.569) between performance on the app-based versions and performance on the traditional versions. Performance score differences by racial group were not statistically significant. Both Black and NHW participants rated the app-based measures as feasible and acceptable, though Black participants endorsed a stronger likelihood of future use. These findings add to the growing literature on remote cognitive testing .

让黑人参与者参与临床研究是国家的优先事项。移动应用程序和远程数据收集可能会增加不同人群的研究机会。这项研究在不同的中年和老年人样本中检验了两种基于移动智能手机应用程序的认知测量的可靠性和可行性。黑人（n = 44； M_年龄= 59.93）和非西班牙裔白人（NHW；n = 50； M_年龄= 61.06）参与者完成了传统的纸质神经心理学测试和两项基于应用程序的测量：箭头和数字匹配。类内相关性表明基于应用程序的版本的性能与传统版本的性能之间的可靠性较差到中等（范围：0.417-0.569）。不同种族组的表现得分差异没有统计学意义。黑人和 NHW 参与者都认为基于应用程序的措施是可行和可接受的，尽管黑人参与者认可未来使用的可能性更大。这些发现为越来越多的远程认知测试文献增添了内容。
