Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The ‘CogStep Phase 2.0’ Intervention will comprise a program of combined home based exercise and psycho-education for a period of 12 weeks. The treatment program comprises two distinct parts:
Exercise Prescription: Immediately following the baseline assessments, an Exercise Physiologist will prescribe six individually tailored strength, balance and/or flexibility exercises based on individual results on physical assessment. In addition, participants will be given aerobic exercise goals to achieve each week. The participant will be prescribed exercises and goals tailored to their individual needs encompassing 6 x strength exercises in combination with an aerobic component e.g. walking/jogging (dependent on their ability), with the aim to reach American College of Sport Medicine exercise Guidelines of 150 minutes of moderate exercise per week.
This will be outlined with the participant and exercise barriers will be discussed to ensure adherence to the exercises at home. Participants will be provided with an exercise workbook including the prescribed exercises (images demonstrating the exercise, instructions for performing the exercise, options for progression or regression of difficulty, and prescribed volume of exercise), and an exercise tracking sheet for each exercise to monitor compliance. In accordance with standard clinical care, the exercise prescription will be reviewed by an Exercise Physiologist at Week 6 to ensure exercise prescription/intensity is appropriate for the duration of the trial.

Psycho-education sessions: Participants will also be given a video CD to take home with a total of 12 sessions, from which participants will be asked to sequentially view one session per week. These will be viewed alongside the implementation of the exercises prescribed. These psycho-education sessions will include 20-30 minute video talks provided by a range of clinicians including Neuropsychologists, Nurses, Clinical Psychologists, Sleep Psychologists, Exercise Physiologists and Nutritionists. Content from the sessions will also be provided in the form of a workbook that will be provided to the participant. This content and the videos have been developed by the Healthy Brain Ageing Program.
The sessions include the following content: Session 1: exercise; Session 2: diet; Session 3: brain and cognition; Session 4: memory strategies for ageing individuals; Session 5: managing medications; Session 6: vascular risk factors; Session 7: feeling safe at home in the community; Session 8: anxiety; Session 9: depression and Session 10: sleep.

Following the viewing of each session, participants will be encouraged to complete the corresponding activities and/or questions in the provided workbook. Each workbook activity will take participants approximately 10 minutes each week. Participants will be able to clarify any questions during monitoring phone calls at weeks 2, 4 and 9, as well as at the week 6 clinical review.

A trained research assistant or other researcher will be asked to administer the monitoring phone calls each week. They will also be asked during this phone call regarding their adherence to the psychoeducation.

Waitlist control
Participants randomized to the control condition will be on a waitlist for treatment and after the 12-week control period, an exercise workbook and psychoeducation workbook with accompanying video CD’s matching that of the ‘CogStep Phase2.0’ Intervention group, will be offered to them. Following randomization, participants will be provided with a handout containing generic exercise information. Mobile phone text messages consisting of general physical activity guidelines and health information will be sent to the waitlist control group on weeks 2, 4, 6 and 9 (to mirror contact time points with the intervention group). The messages will differ between weeks and will be managed via an automated electronic platform. Should the participant not have access to a device to receive these mobile phone text messages, a letter containing the same details will be mailed to the participant.
After the waitlist period, participants will be offered the 12-week exercise program and psychoeducation program. They will also be offered a 6-week review following the start of their programmed if they would like to attend.

Other design features
There will be two groups of participants. During the first 12-weeks of the study procedure, one group will receive an individually tailored exercise program and a video CD containing 12 psychoeducation sessions to complete. Concurrently, the control group will receive a handout containing generic exercise information and will be sent mobile text messages containing general physical activity guidelines and health information. After the intervention group has completed the 12-week intervention period, the waitlist control group will be offered the psychoeducation video CD’s and workbook, matching that of the intervention group.

Efficacy
Statistical methods / analysis
As this is a pilot study, no formal power analyses have been conducted for the purposes of determining sample size and effect sizes needed. This study is exploratory in nature and the outcomes will be used to power a larger, more rigorous randomised controlled trial.

Group differences at baseline will be assessed using independent samples t-tests for continuous data and chi-squared tests for categorical data (such as gender). A repeated measures analysis of variance will be used to examine group differences in primary and secondary outcomes.

Summary
Brief summary
This study aims to investigate whether a 12-week combined psychoeducation and home-based exercise intervention can improve dementia risk, mood, health knowledge, cognition, sleep, metabolic markers and brain connectivity in older adults with cognitive difficulties. The active intervention will comprise an individually prescribed, home-based exercise and psychoeducation program. Results will be compared to an active waitlist control group, who will be offered the psychoeducation program at the end of the trial.
