Long‐term Engagement in a Digital Lifestyle Intervention to Reduce Dementia Risk in Older Adults

Participant engagement suggests that the intervention is accessible to many participants. Long-term application usage suggests the intervention is engaging for some participants. We found that it is participant baseline characteristics, such as age and pre-intervention risk factors rather than the addition of 1-to-1 Virtual Clinic sessions that influenced long-term engagement with the app. These findings warrant further investigation of digital lifestyle interventions for older adults at risk of dementia, particularly into the challenge of maintaining participant engagement. Future work should aim to identify what meaningful participant engagement is and what level of engagement facilitates sustained lifestyle change.
