Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention involves a peer-peer play-based intervention involving self-, therapist, and peer modelling. All intervention sessions will be video-recorded to facilitate self-modelling. The researcher will begin each clinic session by showing the children video footage of themselves playing from the previous week. During the self-modelling, children will observe and reflect on edited video footage of their social play from the previous week. The researcher will use video feedback techniques by discussing the segments of their past play performance. The researcher will then use video feed-forward techniques by facilitating a problem solving discussion with the children, helping them to develop strategies to pre-empt the changes required for future social skill development to occur. To conclude, the researcher will present the children with three key summary points as they enter the playroom to remember and pre-empt play. The parent/caregiver will observe these sessions through use
of a computer monitor in an adjoining room. The researcher will discuss the techniques they used with the caregiver to ensure skills transfer.
The duration between treatments for the treatment and control group is 3 months. The intervention involves a clinic component which includes 1x1 hour session per week for 10 weeks and a home component which involves 1x1 hour session per week for 10 weeks.

Treatment: Other
Comparator / control treatment
Randomized pairwise wait-listed control group. The children will be allocated to either a control or intervention group through pair-wise randomisation after they enter the program. To minimise bias, randomisation will be concealed from the investigator. A person not involved in the study will hand the researcher an envelope determining group membership; the concealed envelope will be given to the family at the end of the baseline assessment to find out their group membership.
The group membership will have been unknown to both participants and the researcher until this point. The control group will be offered the intervention after a 3 month waiting period. The control group will receive standard care during the intervention period.

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)
The crossover of the paired waitlisted control will be immediately after the experimental paired child completed their 10 week intervention. To minimise bias, randomisation will be concealed from the investigator. A person not involved in the study will hand the researcher an envelope determining group membership; the concealed envelope will be given to the family at the end of the baseline assessment to find out their group membership.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Efficacy
Statistical methods / analysis
Comparing between group differences using linear mixed modelling
analysis. Based on a Cohen’s d of 0.8, given an a-value of 0.05 and a 1-Beta of 0.8, 24 children with ASD in each group (n= 48) will be required in order to generate sufficient power of the study.
