The Body, Brain, Life Program –a prevention trial to reduce risk of Alzheimer's Disease

The BBL program is an online, theoretically-driven, multi-domain intervention comprising seven modules (Dementia literacy, Risk factors literacy, engagement in physical, cognitive, and social lifestyles, nutrition, and health monitoring and management). All modules were designed in a manner reflective of current theoretical models of health behaviour change, and with the exception of the first two modules which are primarily educational in nature, will be delivered in an individually-tailored manner. The BBL program was designed to be delivered over 12 weeks, starting with the delivery of the seven modules once per week in a fixed order, and continuing with associated goal-related sessions in the remaining weeks. Participants in the intervention arms will be required to complete online activities 1 hour per week. They will be, however, encouraged to engage with the online material more frequently than that. Arm1; This group will complete the online BBL program as described above over 12 weeks (one hour per week). Arm2: This group will also complete the online BBL program over 12 weeks. However, this group will also participate in weekly face-to-face sessions to evaluate any additional effects of face-to-face contact, over and beyond the effects of the online trial only. Small face-to-face group sessions will be facilitated by a psychologist. The content of these sessions will largely echo the respective online modules. They will include discussion of the various risk factors, and will use motivational techniques to elicit group-level behavioural change dynamics. The small group element will be conducted weekly for 7 weeks with each week focusing on the topic of one of the online modules.]These face-to-face sessions will be of approximately one hour in duration.
