Design outcomes

Primary

Measure	Time frame
Improvement or no improvement at 24 weeks, based on the clinical global impression of improvement (CGI-I)	—

Secondary

Measure	Time frame
Primary Economic Outcome Measure Cost per additional child achieving at least the target improvement in CGI-I scale will be calculated in each pathway Secondary Child Outcome Measures 1. Restrictive Repetitive Behaviours (RRB), measured using Target Behaviour Vignette at baseline, Week 10, Week 24 and Week 52 2. RRB, measured using Repetitive Behaviour Questionnaire - 2 (RBQ-2) at baseline, Week 10, Week 24 and Week 52 3. RRB, measured using Teacher Repetitive Behaviour Questionnaire 2 (Teacher RBQ-2) at baseline, Week 10, Week 24 and Week 52 4. Adaptive functioning, measured using Vineland Adaptive Behaviour Scales III (VABS III) at baseline and Week 24 Parent Outcome Measures 1. Behaviours typically exhibited by children with ASD, measured using parent self-efficacy questionnaire at baseline, Week 10, Week 24 and Week 52 2. Parenting stress specific to core and co-morbid symptoms of ASD, measured using Autism Parenting Stress Index (APSI) at baseline, Week 10, Week 24 and Week 52 3. Wellbeing, measured using Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) at baseline, Week 24 and Week 52 Secondary Family Outcome Measures Autism Family Experience Questionnaire (AFEQ) at baseline, Week 24 and Week 52 Secondary Economic Outcome Measures 1. Healthcare resources which are used by the children, measured using resource use questionnaire at baseline, Week 24 and Week 52. This will be calculated to result in an average cost of services per pathway 2. Costs and time lost to travel, measured using time and travel questionnaire at baseline 3. Health-related quality of life of caregivers reported per child, measured using EQ-5D-5L questionnaire at baseline, Week 24 and Week 52 4. Health-related quality of life of the child with RRB, measured using CHU9D proxy version at baseline, Week 24 and Week 52 Updated 04/04/2019: VABS II changed to VABS III.	—
