Detailed Description
The investigators aim to promote brain health by reducing lifestyle risk factors for dementia in older adults with subjective cognitive decline (SCD). This study is a pilot randomized control trial (RCT) comparing two virtual lifestyle programs, My Healthy Brain 1 and My Healthy Brain 2. Eligible older adults include: age ≥ 60, self-reported worry about changes in memory or thinking, and risk factors for dementia (determined by the Cardiovascular Risk Factors, Aging, and Incidence of Dementia score ≥ 6). Participants will be randomized to one of two groups (My Healthy Brain 1 or My Healthy Brain 2) and will complete 8 weekly 90-minute sessions via Zoom delivered by a clinical psychologist. Each session will focus on a different topic relevant to brain health (e.g. physical activity, sleep, etc.). The primary aim of the study is to determine the credibility, expectancy, feasibility, acceptability, appropriateness, fidelity, and satisfaction of the programs. The investigators will also explore improvements in cognition, lifestyle behaviors (physical activity, sleep, nutrition, alcohol and tobacco use, social functioning), depression, anxiety, and mindfulness assessed at baseline, post-intervention, and 6 month follow-up. All participants will wear a watch to monitor changes in lifestyle during the program.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: My Healthy Brain 1 My Healthy Brain 1 is an 8-week group program delivered via 90-minute Zoom meetings led by a clinical psychologist. It provides education on the link between dementia and lifestyle factors, including poor exercise, sleep, diet/nutrition, mental and social stimulation, alcohol, and smoking. My Healthy Brain 1 participants learn evidence-based mindfulness and behavior change skills to address common barriers to healthy habits, such as stress and setting achievable goals. My Healthy Brain 1 participants wear an activity watch to monitor lifestyle changes during the program. |
Behavioral: My Healthy Brain 1

| Active Comparator: My Healthy Brain 2 My Healthy Brain 2 condition controls for the effect of time spent and support/feedback from the group and interventionist. Participants in My Healthy Brain 2 will receive education on lifestyle, brain health, and cognitive decline symptoms in addition to usual care as determined by their medical team. Each weekly session will focus on a different topic: 1) lifestyle and brain health, 2) physical activity, 3) sleep, 4) nutrition, 5) medical adherence, 6) cognitive health, 7) social support, and 8) a program overview. My Healthy Brain 2 is conducted in the same format as My Healthy Brain 1 (8 weekly Zoom sessions, 90 minutes each), but does not include behavior change strategies. My Healthy Brain 2 participants wear an activity watch to monitor lifestyle changes during the program. |

Outcome Measures
Primary Outcome Measures
- Credibility and Expectancy Questionnaire [0 Weeks]
Assesses how believable, convincing, and logical patients perceive the treatment to be. Higher scores (min = 3, max = 27) scores indicate greater credibility and expectancy.
- Client Satisfaction Questionnaire [8 Weeks]
Assesses patient satisfaction with the program. Higher total scores (min = 3, max = 12) indicate greater satisfaction.
- Rates of Recruitment and Enrollment [0 Weeks]
We will assess the feasibility of recruiting and enrolling participants into the study by calculating the proportion who agree to participate divided by the total number contacted (≥70% good, ≥ 80% excellent).
- Rates of Missing Outcomes Data [8 Weeks]
We will assess the feasibility of data collection by calculating the proportion of secondary outcomes (cognition and lifestyle) with no missing data divided by the total number collected (≥70% good, ≥ 80% excellent).
- Rates of Valid Activity Watch Data (7 or more hours of wear time) [8 Weeks]
We will assess the feasibility of collecting valid activity watch data by calculating the proportion of valid days (7 or more hours of wear time) divided by the total number of days in the program (≥ 70% good, ≥ 80% excellent).
- Rates of Ecological Momentary Assessment (EMA) Data [8 Weeks]
We will assess the feasibility of collecting ecological momentary assessment (EMA) of daily mindfulness practice by calculating the proportion of text-based surveys completed divided by the total number of surveys sent during the program (≥ 70% good, ≥ 80% excellent).
- Rates of Treatment Completion [8 Weeks]
We will assess the acceptability of treatment by calculating the proportion of participants who attend ≥ 6/8 treatment sessions (≥ 70% good, ≥ 80% excellent).
- Rates of Therapist Fidelity to Intervention Procedures [8 Weeks]
We will assess the fidelity of therapists to the intervention procedures by calculating the proportion of sessions with completed audio recordings, progress notes, and checklist with 100% of content delivered divided by the total number of sessions (≥ 75% good, 100% excellent).
- Rates of Staff Fidelity to Study Procedures [8 Weeks]
We will assess the fidelity of staff to the study procedures by counting the frequency of protocol deviations (<5 deviations good, 0 deviations excellent).
- Modified Patient Global Impression of Change at 8 weeks [8 Weeks]
The proportion of participants who report perceived improvements in cognitive function, lifestyle, and emotional well-being outcomes (1=Very Much Worse, 7=Very Much Improved).
- Rate of Adverse Events [8 Weeks]
We will assess the safety of the study by founding the number and severity of adverse events (mild in ≤ 10% of participants = good, none = excellent).
