Summary
Smartphone-based experience sampling is feasible for mild cognitive impairment (MCI) patients, offering dynamic insights into daily functioning. Adherence challenges exist, but this method aids personalized self-management strategies.
Area of Science:
- Gerontology
- Neuroscience
- Digital Health
Background:
- Retrospective questionnaires limit understanding of daily functioning in mild cognitive impairment (MCI).
- Existing methods neglect temporal and contextual fluctuations in cognitive disorder symptoms.
Purpose of the Study:
- To assess the feasibility and usability of the experience sampling method (ESM) via smartphone in individuals with MCI.
- To capture dynamic behavioral, emotional, and cognitive patterns in real-world settings.
Main Methods:
- 21 participants with MCI used a smartphone ESM app for 6 days.
- Participants completed momentary questionnaires 8 times daily on mood, activities, social context, and cognitive complaints.
- Feasibility and usability were evaluated through self-reports and human-technology interaction analysis.
Main Results:
- 18 of 21 participants completed the study with a 78.7% compliance rate.
- Participants found the momentary questions reflective of their daily experiences.
- 72% of participants found increased awareness of memory functions pleasant or neutral.
Conclusions:
- Smartphone-based ESM is generally feasible for individuals with MCI.
- Challenges include smartphone ownership among older adults and adherence for some.
- Momentary data offers valuable insights for tailored self-management strategies in clinical practice.
