Subjective Cognitive Concerns and High Frequency Mobile App Based Cognitive Assessment in Older Adults: Relationship to Adherence, Satisfaction, and Cognitive Performance

SCCs are associated with objective cognitive performance on mobile app-based assessments, but do not impact metrics related to protocol engagement (e.g., adherence, satisfaction, and motivation), suggesting that mobile app assessments may be sensitive to early neurodegenerative changes. Results provide reassurance that SCCs do not impact the feasibility of mobile app-based assessments in older adult samples. Future research in larger, more diverse samples which follow cognitive functioning longitudinally will be essential next steps to understand the utility of SCC to predict cognitive decline via mobile app.
