Brain Health Program for Older Adults With Subjective Cognitive Decline

Assesses how believable, convincing, and logical patients perceive the treatment to be. Higher scores (min = 3, max = 27) scores indicate greater credibility and expectancy.

Assesses patient satisfaction with the program. Higher total scores (min = 3, max = 12) indicate greater satisfaction.

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).

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).

We will assess the feasibility of collecting valid activity watch data by calculating the proportion of participants who wore the watch at least 5 out of 7 days per week for at least 10 or more hours per day, divided by the total number of days in the program (≥ 70% good, ≥ 80% excellent).

We will assess the feasibility of collecting ecological momentary assessment (EMA) of daily mindfulness practice by calculating the proportion of participants who complete at least 5 out of 7 daily surveys per week (≥ 70% good, ≥ 80% excellent).

We will assess the acceptability of treatment by calculating the proportion of participants who attend ≥ 6/8 treatment sessions (≥ 70% good, ≥ 80% excellent).

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).

We will assess the fidelity of staff to the study procedures by counting the frequency of protocol deviations (<5 deviations good, 0 deviations excellent).

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).

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).

A comprehensive test of five cognitive domains (immediate memory, visuospatial/constructional, language, attention, and delayed memory) and global cognition. Higher Z and Index Scores indicate greater cognitive functioning on each domain.

14-item self-report of cognitive and functional status. Higher total scores (min=0, max=14) indicate greater subjective cognitive complaints.

Activity watch change in steps count during the 7 days preceding baseline assessment, throughout the intervention period, and 7 days at 6-month follow-up. Higher step count totals indicate greater physical activity (walking).

8-item self-report of daily functioning. Higher T scores (mean = 50, sd = 10) indicate greater physical function.

Activity watch change in total sleep time during the 7 days preceding baseline assessment, throughout the intervention period, and 7 days at 6-month follow-up. Higher total minutes indicate greater sleep time.

9-item self-report of sleep patterns and overall quality. Higher total scores (min=0, max=21) indicate greater sleep disturbance (>5 = clinically significant).

16-item self-report of adherence to Mediterranean dietary recommendations. Higher total scores (min=0, max=21) indicate greater intake/adherence of Mediterranean foods.

7-item self-report of at-risk drinking. Higher T scores (mean = 50, sd = 10) indicate greater problematic alcohol use.

2-item self-report of the frequency and use of 6 common tobacco products (1=Less than once a month, 5=Daily or almost daily).

8-item self-report measure of satisfaction of performing usual social roles and activities. Higher T scores (mean = 50, sd = 10) indicate greater satisfaction with social roles and activities.

10-item self-report measure of frequency of certain cognitive activities (e.g. reading newspapers, playing music, etc). Higher total scores (min=0, max=10) indicate greater participation in cognitively stimulating activities.

13-item self-report that assesses the variety and extent to which an individual compensates for actual or perceived memory losses. Higher total scores (min=0, max=65) indicate greater utilization of memory compensation strategies.

3-item self-report of weekly engagement in light, moderate, and vigorous physical activities. Higher average scores indicate greater engagement in total physical activity.

10-item self-report measure of perceived frequency of specific social activities. Higher total scores (min=0, max=50) indicate greater participation in socially engaging activities.

5-item self-report of perceived loneliness. Higher T scores (mean = 50, sd = 10) indicate greater perceived loneliness.

4-item self-reports of each construct. Higher T scores (mean = 50, sd = 10) indicate greater depression and anxiety.

15-item self-report of using basic mindfulness principles. Higher total scores (min=0, max=60) indicate greater utilization in daily mindfulness activities.

13-item self-report of control over unwanted experiences. Higher total scores (min=13, max=52) indicate greater daily utilization of cognitive control and flexibility.

10-item self-report of emotion regulation strategies. Higher total scores (min=10, max=70) indicate greater utilization of emotional regulation strategies.

27-item self report of motivation and perceived self-efficacy of lifestyle and health behavior change for dementia risk reduction. Higher total scores (min=27, max=135) indicate greater motivation to alter lifestyle factors and health behaviors to reduce risk of dementia.
