Examining the stability of dementia‐relevant speech measures in a high‐frequency picture description task repeated over 5 days

Speech patterns appear to be stable and reliable in high-frequency administration of the picture description task. Repeated administration may entail learning and/or test familiarity effects as evidenced by longer descriptions throughout testing. Averaging the two pictures led to the highest reliability estimates, suggesting that multiple administrations of the task may be optimal. This research demonstrates that picture description is an ecologically valid, low burden task suitable for remote, higher-frequency, longitudinal testing. Future work will probe how these effects carry over to MCI and AD populations.
