Description of intervention(s) / exposure
An online intervention targeting self-efficacy to self-manage cancer-related fatigue (CRF). The online intervention consists of six sessions that will be completed across a 12 week period. Each session takes approximately 30 minutes to complete. The content of each session is summarised below:

Session 1 (About Fatigue) provides education about CRF, including how it is commonly experienced by people with a primary brain tumour and what the possible causes and impacts are. It includes video animations of patient narratives about their experiences of CRF. Participants are asked to identify areas of their life affected by fatigue that they would like to focus on throughout the intervention. An optional quiz on CRF is provided for those who would like to assess their own knowledge.

Session 2 (Making Plans) introduces the concept of self-monitoring and setting plans to address fatigue using SMART goals (i.e. specific, measurable, attainable, relevant, and time bound). Possible barriers to following plans are discussed and video animations of patient narratives describing the usefulness of setting plans to manage fatigue are included. External links to useful resources are also provided.

Session 3 (Home and Lifestyle) describes how CRF may impact on aspects of everyday life including home life, and how setting effective plans can help to manage this interference. Impacts of CRF on exercise, housework, laundry, childcare, diet, grocery shopping, sleep and meal preparation are discussed, along with strategies for managing these impacts. External links to useful information and resources are provided.

Session 4 (Work) focuses on how CRF can impact on work and provides strategies for managing these impacts including by setting effective plans. External links are provided to useful information and resources.

Session 5 (Thoughts & Feelings) focuses on how thoughts and feelings can impact CRF and how this can be managed using CBT principles, as well as by setting effective management plans. It discusses self-esteem, uncertainty, stress, worry and anxiety, and negative thoughts and feelings generally, and provides strategies for helping to manage them. External links to additional information and resources are provided.

Session 6 (Talking to Others) describes the difficulties of talking to others about CRF and introduces strategies to help manage this, including through setting effective plans. It includes strategies for talking to employers, friends and family, health professionals, and choosing not to talk. External links to useful resources are provided.


Activities are available throughout each session. These include an online fatigue diary participants can use to monitor their fatigue from day-to-day, in addition to single-item assessments of fatigue at the beginning of each session. Stories (video animations) from people with primary brain tumour are included throughout to provide examples of how people with a brain tumour are affected by CRF and strategies they have used to help them manage. Automated tailored feedback based on goal-related progress and change in fatigue levels from the previous session are included throughout and links are provided to additional information and useful resources relevant to each session. Participants can pause completion and return to a particular session either later that same day or on a different day if necessary. During the trial, patients will receive automated emails encouraging them to complete their session or begin the next session if they have not done so within 14 days. Similar emails will be sent to prompt completion of outcome measures. If participants choose not to complete a particular session they will be asked to provide a reason.

Adherence to the intervention will be captured using website analytics.

Rehabilitation
Comparator / control treatment
An online relaxation intervention consisting of six sessions that will be completed across a 12 week period. Each session takes approximately 30 minutes to complete. Each online session is self-guided and will be undertaken independently by the participants. Each session is based on a manualized relaxation training program for cancer patients, The online sessions will deliver training in progressive and passive muscle relaxation, meditative relaxation, visualisation and “quick relaxation” techniques, with regular homework exercises between sessions. The training is delivered via text-based materials and audio-recordings of relaxation training exercises.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be generated by a statistician blinded to the identity of participants, using computer-generated random numbers. A research assistant will notify participants of their group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The random allocation sequence will be generated by a statistician using permuted blocks of size 4 and 6 in REDCap. Participants will be randomly assigned to receive either the RESTORE-BT or relaxation intervention in a 1:1 ratio. Randomisation will be stratified by (i) low vs high grade tumour; (ii) active treatment (i.e. Chemoradiation or clinical trial participation) versus not; (iii) h moderate (i.e. score 4-6 on ESAS) versus severe (i.e. score 7-10 on ESAS) fatigue; (iv) fully active or slightly restricted (0-1 ECOG score) versus limited ability to perform daily activities (ECOG 2); and (v) less than versus more than two years post diagnosis; these characteristics will be participant-reported.

Efficacy
Statistical methods / analysis
The primary outcome is Perceived Self Efficacy for Fatigue Self-Management, a 6-item scale with the total score ranging from 0-10.

We plan to recruit approximately 200 participants. This number is based primarily on practical considerations including the estimated number of eligible participants and the time frame for the study. A study of 200 participants has 80% power at 5% two-sided significance level to detect a difference in mean self-efficacy scores between groups, assuming a true difference in means of 0.45 standard deviations and loss to follow-up of approximately 20%. In the Foster study (Foster et al., 2015) the between-participant standard deviation of self-efficacy scores was approximately 2.2, so a difference of 0.45 SDs corresponds to a difference in means of approximately one unit on the outcome scale of 0-10.

The primary analysis will use a linear model to compare scores at T1 (12 weeks after baseline) between randomised groups with adjustment for baseline score. If the within-participant correlation between baseline and T1 scores is greater than zero, the power will increase or a smaller true difference can be assumed. For example, with correlation of 0.5 between baseline and T1 scores in the same participant a true difference of 0.39 SDs can be assumed.
