Evaluation of the Implementation and Effectiveness of Community-Based Brain-Computer Interface Cognitive Group Training in Healthy Community-Dwelling Older Adults: Randomized Controlled Implementation Trial

Background Cognitive training can improve cognition in healthy older adults. Objective The objectives are to evaluate the implementation of community-based computerized cognitive training (CCT) and its effectiveness on cognition, gait, and balance in healthy older adults. Methods A single-blind randomized controlled trial with baseline and follow-up assessments was conducted at two community centers in Singapore. Healthy community-dwelling adults aged 55 years and older participated in a 10-week CCT program with 2-hour instructor-led group classes twice a week. Participants used a mobile app to play games targeting attention, memory, decision making, visuospatial abilities, and cognitive flexibility. Implementation was assessed at the participant, provider, and community level (eg, reach, implementation, and facilitators and barriers). Effectiveness measures were the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Color Trails Test 2 (CTT-2), Berg Balance Scale, and GAITRite walkway measures (single and dual task gait speed, dual task cost, and single and dual task gait variability index [GVI]). Results A total of 94 healthy community-dwelling adults participated in the CCT program (mean age 68.8 [SD 6.3] years). Implementation measures revealed high reach (125/155, 80.6%) and moderate adherence but poor penetration of sedentary older adults (43/125, 34.4%). The effectiveness data were based on intention-to-treat (ITT) and per-protocol (PP) analysis. In the ITT analysis, single task GVI increased (b=2.32, P=.02, 95% CI [0.30 to 4.35]) and RBANS list recognition subtest deteriorated (b=–0.57, P=.01, 95% CI [–1.00 to –0.14]) in both groups. In the PP analysis, time taken to complete CTT-2 (b=–13.5, P=.01, 95% CI [–23.95 to –3.14]; Cohen d effect size = 0.285) was faster in the intervention group. Single task gait speed was not statistically significantly maintained in the intervention group (b=5.38, P=.06, 95% CI [–0.30 to 11.36]) and declined in the control group (Cohen d effect size = 0.414). PP analyses also showed interaction terms for RBANS list recall subtest (b=–0.36, P=.08, 95% CI [–0.75 to 0.04]) and visuospatial domain (b=0.46, P=.08, 95% CI [–0.05 to 0.96]) that were not statistically significant. Conclusions CCT can be implemented in community settings to improve attention and executive function among healthy older adults. Findings help to identify suitable healthy aging programs that can be implemented on a larger scale within communities.

CONSORT-EHEALTH (V 1.6.1) -Submission/Publication Form The CONSORT-EHEALTH checklist is intended for authors of randomized trials evaluating web-based and Internet-based applications/interventions, including mobile interventions, electronic games (incl multiplayer games), social media, certain telehealth applications, and other interactive and/or networked electronic applications. Some of the items (e.g. all subitems under item 5 -description of the intervention) may also be applicable for other study designs.
The goal of the CONSORT EHEALTH checklist and guideline is to be a) a guide for reporting for authors of RCTs, b) to form a basis for appraisal of an ehealth trial (in terms of validity) CONSORT-EHEALTH items/subitems are MANDATORY reporting items for studies published in the Journal of Medical Internet Research and other journals / scientific societies endorsing the checklist.
As the CONSORT-EHEALTH checklist is still considered in a formative stage, we would ask that you also RATE ON A SCALE OF 1-5 how important/useful you feel each item is FOR THE PURPOSE OF THE CHECKLIST and reporting guideline (optional).
Mandatory reporting items are marked with a red *. In the textboxes, either copy & paste the relevant sections from your manuscript into this form -please include any quotes from your manuscript in QUOTATION MARKS, or answer directly by providing additional information not in the manuscript, or elaborating on why the item was not relevant for this study. yes: all primary outcomes were significantly better in intervention group vs control partly: SOME primary outcomes were significantly better in intervention group vs control no statistically significant difference between control and intervention potentially harmful: control was significantly better than intervention in one or more outcomes inconclusive: more research is needed Other: Approx.

Specify how participants who did not use the application or dropped out from the trial were treated in the statistical analysis (a complete case analysis is strongly discouraged, and simple imputation techniques such as LOCF may also be problematic [4]).

17a-i) Presentation of process outcomes such as metrics of use and intensity of use
In addition to primary/secondary (clinical) outcomes, the presentation of process outcomes such as metrics of use and intensity of use (dose, exposure) and their operational definitions is critical. This does not only refer to metrics of attrition (13-b) (often a binary variable), but also to more continuous exposure metrics such as "average session length". These must be accompanied by a technical description how a metric like a "session" is defined (e.g., timeout after idle time) [1] (report under item 6a).

Trainers' in-class guidance and encouragement motivated participants to continue with classes and increasingly cognitively demanding games. A few expressed interests in more advanced level CCT. Barriers to program participation included busy schedules, loss of interest in CCT, and loss to follow-up.
A few cited fatigue from prolonged screen use, noisy class environment, di culty in selected games, and belief that CCT was ineffective.

CCT also promoted maintenance of single task gait speed. We showed that it was feasible to implement community-based CCT in community centers to promote cognitive improvements and maintenance of gait speed in healthy older adults.
Implementation measures revealed high reach and moderate adherence but poor penetration of sedentary older adults. Most community center users were physically and socially active. Participants paid for and attended 80% classes.
Attendance was higher in the intervention group than the control group. However, 25% dropped out and 22% did not adhere to randomization mainly. Implementation was facilitated by CCT trainers' in-class guidance and encouragement, participants' proximity to and strong community ties at implementation sites, resource availability, strong community partnerships, staff buy-in, and prior program implementation experience.

Implementers should consider participants' proximity to implementation sites, strength of community ties, resource availability, staff buy-in, and prior program implementation expertise when shortlisting implementation sites. Future studies can explore the effectiveness of community based CCT for older adults who are sedentary or at risk of cognitive impairment. "

20-i) Typical limitations in ehealth trials
Typical limitations in ehealth trials: Participants in ehealth trials are rarely blinded. Ehealth trials often look at a multiplicity of outcomes, increasing risk for a Type I error. Discuss biases due to non-use of the intervention/usability issues, biases through informed consent procedures, unexpected events.

In-class guidance and timely technical support mitigated technological barriers faced by older adults and likely boosted receptiveness to CCT. Attendance was comparable to other local studies with community-based interventions [25][26][27].
However, dropout rate was higher (25%) even though participants paid a subsidized fee to attend. The target population (i.e., sedentary healthy older adults) could not be recruited at community centers. Instead, the inclusion criterion was relaxed to include older adults regardless of their exercise frequency. This, together with their high educational attainment and participation in various community center programs, likely limited CCT's effectiveness. We encountered di culty recruiting enough sedentary older adults. In addition, the dropout rates were highest in the older adult group. This may suggest that the implementation in its current form is not suitable for the population at the community centers. Online implementation option of group training should be considered in the future, especially in the context of COVID-19 pandemic. "
