Currently submitted to: JMIR Research Protocols

Date Submitted: Mar 27, 2020
Open Peer Review Period: Mar 27, 2020 - May 22, 2020
(closed for review but you can still tweet)

NOTE: This is an unreviewed Preprint

Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).

Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer-Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.

Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).

Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.

Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.

Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.

Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.

Increasing physical activity, improving diet and doing 'brain training' exercises are associated with reduced cognitive decline in older adults. Here we describe a feasibility trial of the Active Brains intervention, an online digital intervention developed to support older adults to make these three healthy behaviour changes associated with cognitive health.


The Active Brains trial is a randomised feasibility trial that will test how accessible, acceptable and feasible the Active Brains intervention is and the effectiveness of the study procedures that we plan to use in our larger main trial.


We will be trialling the intervention with two populations: 1) older adults with signs of cognitive decline, 2) older adults without any cognitive decline. Trial participants will be randomly allocated to one of three study groups: 1) usual care or 2) the Active Brains intervention, or 3) the Active Brains website plus brief support from a trained coach (over the phone or by email). The main outcomes are performance on cognitive tasks, Quality of Life (using EQ-5D-5L), Instrumental Activities of Daily Living and diagnoses of dementia. Secondary outcomes (including depression, enablement and healthcare costs) and process measures (including qualitative interviews with participants and supporters) will also be collected.


Results will be published in peer-reviewed journals, presented at conferences and shared at public engagement events.


The findings of this study will help us to identify and make important changes to the website, the support received or the study procedures before we progress to our main randomized phase III trial. Clinical Trial: Trial registration number: ISRCTN 23758980
