Description of intervention(s) / exposure
The Alfi Virtual Reality programme (Alfi VR) is a novel, adaptive, game-based program designed to train inhibitory control in adolescents. Alfi VR is delivered using a HTC Vive headset and controllers, using immersive virtual reality technology. Participants complete 16 twice weekly training sessions over a period of 8 weeks. Training is delivered individually, face to face by trained research assistants. In the game participants are required to complete an Anticipated Response Task, set in a fantasy world where they must protect a magic crystal from dragons. Each training sessions last approximately 20 minutes. Participants must initiate a response and then either complete or inhibit the response based on visual cues. Training sessions are completed at the participants school, during class time. Compliance is defined as having completed 12 of the 16 allocated training sessions.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group allocation will be completed by a research assistant from within the research group, who is not otherwise assigned to the trial and therefore is not involved in recruitment, screening, enrollment or assessment. Allocation sequences will be generated and concealed in sequential, opaque, sealed envelopes. The participant's study ID will be provided to the research assistant to be recorded on the envelope, prior to the envelope being provided to trial researchers responsible for enrollment and assessment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified, block randomisation using a computer program (R)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Possible mediating and predictive factors such as anxiety, emotional and behavioural problems, Autism features, family functioning and socioeconomic status will be assessed.

Anxiety, emotional and behavioural problems and family functioning will be assessed at the baseline assessment and the post-training assessment using the Spence Children's Anxiety Scale, The Child Behaviour Checklist (Parent report) and the Family Assessment Device respectively.

Socio-economic status and Autism features will be measured during the screening and enrollment stage through use of a demographic questionnaire and the Social Responsiveness Scale 2nd Edition respectively.

Children will be screened using standardised measures of cognitive functioning (the Kaufman Brief Intelligence Test - 2nd Edition) and attention (the Conners-3 Parent Rating Scale) to confirm eligibility.

The NEPSY-II will be used to measure social cognition by assessing affect recognition and theory of mind.

Efficacy
Statistical methods / analysis
A priori power analysis was conducted in G*Power V.3.1 to determine the necessary sample size required to detect significant changes in inhibitory control from pre-training (baseline) to post-training. A sample size of 98 was required for a Medium effect (f=0.25) and a power of 80%. The study will therefore aim to recruit 100 participants, with 50 per group assuming a 1:1 allocation ratio.

Latent Growth Curve Modelling will be used to compare primary and secondary outcomes from the post-training assessment across groups.
