Small Monetary Incentives for Digital Cognitive Training Adherence in Community-Dwelling Older Adults

This study aims to find out whether small daily monetary rewards can help older adults living in the community to regularly complete digital cognitive training. Cognitive training is a promising way to maintain or improve memory and thinking skills in older adults, but many people find it hard to keep training every day. Small rewards, such as a few cents or one yuan per day, have been shown to encourage healthy behaviors in other areas. However, it is not clear whether such rewards are effective for cognitive training. The investigators plan to enroll 110 adults aged 60 years or older who can use a smartphone. Participants will be randomly assigned to one of four groups: a control group that receives no money, and three groups that can earn up to 0.2, 0.5, or 1 yuan per day for completing daily cognitive training tasks. The training takes about 15-20 minutes per day and is done through a mobile app. The study lasts 12 weeks with training, followed by 4 weeks without rewards to see if participants continue training. The main question is whether the groups that receive money complete more training days than the control group. The investigators will also examine whether higher rewards lead to better adherence, whether cognitive function improves, and whether the effects differ by income level. This study may provide a low-cost way to help older adults stay engaged in cognitive training and reduce the risk of cognitive decline.

Pilot Study of a Brain Health Program in Senior Centers

The investigators will evaluate a brain health programs in older adults with subjective cognitive decline. The primary aim of the study is to determine the credibility, expectancy, feasibility, acceptability, appropriateness, fidelity, and satisfaction of the program delivered in the senior centers.

The Brain Health PRO Online Risk Factor Reduction Study to Prevent Dementia

This study will recruit participants at risk for dementia to participate in an online educational program called Brain Health PRO (BHPro). The BHPro intervention is designed to address modifiable risk factors for dementia through a 6-month, fully online, educational program conveying the best available evidence for lifestyle changes that can mitigate dementia risk, and foster engagement toward one's own brain health. Achieving lifestyle changes in a diverse Canadian population through online education would be a major achievement in dementia prevention in Canada, with widespread personal and socioeconomic benefits. Eligible participants will be randomly assigned to either start Brain Health PRO immediately or in 6 months (delayed-start control group). All participants will have the opportunity to have access to BHPro for 6 months during the course of the study and will have open access to all content for 12 months following the initial 6-month intervention. Participation will last from 18-24 months depending on group assignment.
