Study Overview
Brief Summary
The overarching aim is to develop and deploy a multidomain intervention delivered on a mobile application to help middle-aged to older adults reduce their risk for dementia by improving a set of modifiable lifestyle risk factors associated with cognitive decline/dementia. This registration concerns the Pilot Feasibility study which examines different aspects of feasibility in a small-scale randomized pilot study, before implementing an efficacy study on a larger sample. A secondary objective is to determine whether the program can result in a larger improvement on risk factors (measured with Behavioural Risk outcomes) compared to a control intervention. It is expected that persons enrolled in the Luci program show larger change in Behavioural Risk outcomes than those enrolled in the comparator condition.
Detailed Description
Multidomain lifestyle interventions show promising results in reducing the risk of cognitive decline and dementia.
In this study, we pilot the feasibility of a coach-based digital multidomain risk-reduction program to improve cognitive engagement, physical activity, and healthy eating in older adults at risk of dementia. This trial is the second step in the clinical validation process of the Luci program (see NCT04616794). In this 24-week study, participants are randomly assigned to the Luci Intervention group or to the Waiting-list Control group (i.e., participants receive the program after the end of the trial). Assessments will be done at study entry (T1), week 12 (T2), and week 24 (T3).

Arms & Interventions
Luci Intervention
Participants enrolled in this group will receive the Luci intervention for a 24-week period.
Intervention: Luci Coach Assisted Intervention (Behavioral)
Wait-list Control
Participants in the waiting-list control group will not receive any intervention during the study. They will be invited to participate to the program at the end of the trial.
Outcomes
Primary Outcomes
Acceptability of randomization
Time Frame: Week 24
Acceptability of randomization will be assessed by comparing the post-randomization dropout rate in the control group relative to the intervention group.
Retention rate
Time Frame: Week 24
Retention rate will be calculated as the proportion of randomized participants completing at least one of the measures at study end.
Enrollment Ratio
Time Frame: At baseline post-enrollment
Screening-to-enrollment ratio will be calculated as the number of enrolled participants over the number of screened participants.
Recruitment Rate
Time Frame: At baseline post-randomization
Recruitment rate will be calculated as the number of participants randomized per month over the recruitment period
Program adherence
Time Frame: Week 24
Program adherence will be calculated as the number of participants from the Luci condition who attend at least 66% of the prescribed coaching sessions over the 24-week intervention period.
