Summary
The experience sampling method (ESM) is feasible for studying communication in primary progressive aphasia (PPA). While acceptable to care partners, cognitive-linguistic impairments affected participant acceptability.
Area of Science:
- Neurology
- Linguistics
- Human-Computer Interaction
Background:
- Primary progressive aphasia (PPA) significantly impacts communication abilities.
- Understanding communication behaviors in daily life is crucial for PPA management.
- The experience sampling method (ESM) offers a potential tool for ecological assessment.
Purpose of the Study:
- To assess the feasibility and acceptability of ESM for characterizing communication in PPA.
- To describe communication modality usage in individuals with PPA and their care partners.
Main Methods:
- Five PPA participant-care partner dyads participated.
- A 1-week ESM data collection period involved twice-daily text-based surveys.
- Semistructured interviews, System Usability Scale, and adherence rates were used for evaluation.
Main Results:
- High adherence was observed: 100% survey completion by PPA participants and 96% by care partners.
- ESM acceptability varied among PPA participants but was generally good for care partners.
- Unaided communication (speech, gesture, facial expressions) was most frequent, with varied use of other modalities.
Conclusions:
- ESM is a feasible method for assessing daily communication in PPA.
- Acceptability challenges exist for PPA participants due to cognitive-linguistic impairments.
- ESM shows promise for ecological characterization of PPA communication.
