Description of intervention(s) / exposure
TALI Train is a gamed-based computerised training program, delivered on a tablet. The program comprises of four different activities, each lasting 4 minutes in duration. In total, sessions take 20 minutes to complete. Children will be required to complete five sessions per week for five weeks. TALI Train will be used in the child's home, and under the supervision of a parent or guardian.

The intervention targets the 3 core attention networks and related cognitive attention processes: selective attention, sustained attention and attentional control. Children may complete the activities in any order, but must complete all activities each session.

Over time, as children progress through the levels within each activity, the tasks should become more difficult. TALI Train has been designed to be adaptive to the skill of the child. When children respond incorrectly, or fail to respond, prompts are given and levels become easier until the child begins to make correct responses again. Each session the child recommences the activities at the level they finished on during their last session.

Children are rewarded for successful completion of an activity with a virtual toy. TALI Train is designed so that children are locked out following completion of a session until midnight, to ensure that only one session is completed each day.

Adherence to the intervention program will be assessed via the Tali web portal, during weekly phone calls with an unblinded member of the research team, and parents will complete a motivation log for each session.

Comparator / control treatment
The active control program has been developed by Monash University, based on the TALI Train program. It is computerised, game-based and delivered on a tablet in the child's home under supervision of a parent or guardian.

The active control task utilises the same characters and rewards as TALI Train and sessions run for the same duration as the TALI program (e.g. 4 exercises each 4 minutes in duration). As in the intervention group, children will be required to complete 5 sessions a week for a period of 5 weeks.

This program requires children to use basic motor skills to touch, drag, move and rotate shapes around a screen. Importantly this program was designed to involve minimal attentional skills, and unlike TALI Train is not adaptive. Therefore, children complete the same exercises each day with no increase in complexity.

Adherence to the active control program will be assessed during weekly phone calls with an unblinded member of the research team, and parents will complete a motivation log for each session.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A statistician not directly involved in the analysis of the study results will be responsible for the implementation of the allocation. The documentation pertaining to the randomisation will be securely stored and inaccessible to researchers undertaking recruitment and testing. Researchers conducting screening and assessments will be unaware of group allocation for the duration of the trial (including data analysis). Prior to the commencement of each assessment session participants will be explicitly instructed not to discuss the contents of their assigned program with the researcher. Group allocation details and randomisation codes will only be available once all data collected have been entered into the study database for every participant and the database has been finalised, except in the case of an emergency. For any participant for whom the study blind is broken, the date, time, participant ID and reason for unblinding must be documented.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation (ratio 1:1, with blocks of 4) will be used to maintain balance between intervention arms. Computer-generated random numbers will be used to allocate participants. The randomisation will be stratified by injury severity (mild, moderate-severe, unknown).

Efficacy
Statistical methods / analysis
Latent growth curve modelling (LGCM) will be used to examine changes in attention over time. A multi-group approach will be used so that the trajectories of the intervention group with the active control group can be compared. LGCM will also allow for examination of other factors which predict improvement.

A sensitivity analysis will be conducted to assess whether training outcomes differed for those who did (compliers) and did not (non-compliers) adhere to the required training schedule.

To determine the sample size required to detect significant changes in the primary outcome measures from baseline to post-training (between-subjects), we conducted a priori power analysis using G*Power version 3.1.

For a power of 80%, a sample size of 40 is required to detect a large effect (f = 0.40) and a sample size of 98 for a medium effect (f = 0.25). Previous cognitive training RCTs (Laine, Fellman, Waris, & Nyman, 2018) have reported medium to large effect sizes (eta squared range 0.15 - 0.27). Therefore, assuming an allocation ratio of 1:1, a sample between 40 and 98 participants should be sufficient to achieve adequate statistical power.
