Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention (AP) will be provided to all participants. It involves a one-on-one face to face consultation weekly for 1 hour for 10 weeks (10 hours total) to be held in the UON Occupational Therapy Clinic. The occupational therapist, child participant and caregiver will be involved in each session and there will be recommendations for follow up and carry over at home. The AP combines principles of cognitive behavioural therapy and sensory integration. The AP is a three-stage active learning program. In Stage 1, an engine analogy is used to explain the concepts of arousal and self-regulation (slow engine=low arousal, sluggish feeling; high engine=high arousal, out of control; just right engine= just right arousal for learning, playing, getting along). Stages 2 and 3 introduce and implement the concept of ‘sensory diet’, where the sensory environment and specific child sensory needs are considered in optimising child arousal and regulation for the activity and environment. Usefulness of the AP has been documented with preschool through early adolescent aged children. Sensory diets are commonly used with children by occupational therapists and are endorsed for use with children with ASD by the American Occupational Therapy Association. AP has been shown effective in improving self-regulation and behaviour in children with emotional disturbance. Sessions will be conducted by a qualified occupational therapist blinded to the sensory subtype of the child. Intervention sessions will be videoed for the purposes of review of intervention fidelity. The occupational therapist will keep session notes after each session detailing attendance, content of the session, child progress and adherence to home activities.

Efficacy
Statistical methods / analysis
All participants in the study will receive the AP intervention. Differences in outcomes between groups will be analysed by pre-existing exposures, namely, sensory subtype. Participants will be classified according to their scores in Reactive and MSI sensory subtypes using the Short Sensory Profile (parent report) on entry to the study. A pre-established algorithm developed by the lead CI will be used to determine subtype scores (i.e. Reactive or MSI). Outcome assessors and intervention therapists will be blind to subtype classification.

Pre- and post-test difference scores will be calculated for each outcome variable according to the relevant measurement conventions. These scores will be submitted to analysis using the General Linear Model for repeated measures to assess differences between matched Reactive and MSI pairs. There is insufficient literature to determine a priori power.
