The Canadian Therapeutic Platform Trial for Multidomain Interventions to Prevent Dementia (CAN-THUMBS UP, or CTU) is a comprehensive and innovative program aimed to develop, implement and evaluate an interactive and compelling online educational Brain Health Support Program (BHSP) intervention, called Brain Health PRO (BHPro), with potential to positively influence dementia literacy, lifestyle risk factors, and scale-up to reach the broader Canadian public; enroll and retain a community-dwelling Platform Trial Cohort (PTC) of individuals at risk of dementia; and support an open platform trial to test a variety of multidomain interventions that might further benefit individuals at risk of dementia.

Change in Dementia Literacy From Baseline to Month 12
The primary outcome will be change in dementia literacy following participation in the study, as measured by the Alzheimer's Disease Knowledge Scale (ADKS). The ADKS is designed to assess knowledge about Alzheimer's Disease (AD) among laypeople, patients, caregivers, and professionals. This self-report questionnaire contains 30 true/false items. The total score is the sum of the scores from the 30 items, which is quantitative and ranges from 0-30, with a higher score indicating better knowledge about AD. To aide interpretation, change in ADKS scores were converted to standardized change scores by dividing the covariate-adjusted least squares mean change by the baseline standard deviation. The results reported are the standardized change on the scale from baseline to month 12. The converted to standardized score range is -10.81 to +10.81. The greater the positive change in score, the greater the increase in knowledge of dementia.
Time frame: 12 months
Change in Self-efficacy From Baseline to Month 12
Change in self-efficacy following participation in the study, as measured by the General Self-Efficacy Scale (GSE). The GSE measures perceived competence in dealing with a range of stressful or challenging situations. This self-report questionnaire contains 10-items, each rated on a 4-point scale (not true at all, hardly true, moderately true, exactly true). The total score is the sum of the scores for the 10 items, which is quantitative and ranges from 10-40, with a higher score indicating more self-efficacy. To aide interpretation, change in GSE scores were converted to standardized change scores by dividing the covariate-adjusted least squares mean change by the standard deviation. The results reported are the standardized change on the scale from baseline to month 12. The converted to standardized score range is -7.39 to +7.39. The greater the change in score, the greater the increase in self-efficacy.
Time frame: 12 months
To Evaluate Usability of BHPro
Based on System Usability Scale (SUS). The SUS is an 11-item questionnaire with 5-point Likert scale. The total raw score ranges from 0-43 with a higher score indicating greater usability and satisfaction with Brain Health Pro.
Time frame: 12 months
Number of Chapters Completed on BHPro
To evaluate engagement with Brain Health PRO, the number of chapters completed on BHPro was calculated. There is a total of 180 chapters (181 when orientation chapter is included) that are available on BHPro. The program allows participants to view 160 chapters (excluding the orientation chapter) when reaching week 45 (the intended length of the BHPro program). After 45 weeks, the remaining chapters that were still locked will become accessible for users interested in viewing all the program content. The range of chapters that could be completed on Brain Health PRo by participants is 1-181, with a higher number indicating higher engagement with the program.
Time frame: 12 months
To Evaluate User Acceptance of BHPro With the Technology Acceptance Model Questionnaire (TAMQ).
Based on Technology Acceptance Model Questionnaire. The TAMQ is a 20-item questionnaire (adapted for BHPro) with 7-point scale. The total score ranges between 0-120, with a higher score indicating greater acceptance and satisfaction with BHPro.
