Feasibility of Digital Memory Assessments in an Unsupervised and Remote Study Setting
Sensitive and frequent digital remote memory assessments via mobile devices hold the promise to facilitate the detection of cognitive impairment and decline. This study, based on a Germany-wide Citizen Science project with 1407 participants (aged 18-89), investigated the feasibility of the three tasks of the neotiv digital cognitive assessment battery, completed on a weekly basis for 12 weeks in an unsupervised setting. For each memory task, 12 independent parallel test sets were used to minimize the effects of repeated testing. A mean participant retention time of 44 days was observed and a 77.5% compliance to the study protocol with no contact between participants and study personnel, payment or feedback. In addition, only minor practice effects associated with repeated cognitive testing were found, and reveal evidence for acceptable-to-good retest reliability of the mobile assessments. The study further shows that memory performance was strongly associated with age in all paradigms, and individuals with subjectively reported cognitive decline presented lower mnemonic discrimination accuracy compared to non-complaining participants. Hence, the study demonstrates the feasibility of fully unsupervised digital remote memory assessments.
