Self-Administered Mobile Cognitive Assessments for Individuals with Stroke: A Feasibility and Validation Study.

Key Points

This study aims to explore the feasibility and validity of mobile cognitive assessments among individuals with stroke.
Longitudinal observational design including 20 participants with mild-to-moderate stroke.
Participants completed a smartphone-based protocol over 14 days involving ecological momentary assessments and mobile cognitive tasks.
Lab-based neuropsychological tests were also administered at initial visit for comparison.
High adherence rates for mobile assessments ranged from 77% to 85%.
Learning effects were significant across most tests (p < 0.024 to 0.001), except for one test.
Stability estimates were variable, with stronger concordance for memory-related assessments compared to inhibition tasks.

Abstract

OBJECTIVE: To examine the feasibility, learning effects, stability, and validity of mobile cognitive assessments (MCAs) among individuals with stroke. DESIGN: Longitudinal observational study utilizing frequent, brief, repeated, in vivo self-administered mobile assessments of cognitive functions. SETTING: Everyday life settings. PARTICIPANTS: 20 participants with mild-to-moderate stroke (mean age: 55.5 years; 60% men; 45% Whites; 70% ischemic stroke). INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Over 14 days, participants used smartphones to complete a digital assessment protocol. The protocol included six ecological momentary assessment (EMA) surveys on self-reported health status, along with four mobile cognitive assessments (MCAs), each administered twice daily. MCAs included the Mobile Stroop Color Word Test (M-SCWT), Mobile Spatial Memory Test (M-SMT) Forward and Backward, Mobile Trail Making Test Parts A and B (M-TMT A this study is not defined as a clinical trial.
