Description of intervention(s) / exposure
In a double blind, randomized controlled trial, young people with Autism Spectrum Disorders are randomly assigned to receive an 8-week course of oxytocin nasal spray (Syntocinon) or a placebo nasal spray. Participants or their carers administer the nasal spray twice daily (morning and night). Participants aged between 12 and 15 receive 18 international units at each administration. Participants aged between 16 and 18 receive 24 international units. Participants are assess before the trial commences, 4-weeks into the trial (midpoint), at treatment completion (8-weeks from commencement) and three months following treatment completion. At each assessment point participants complete a range of assessments, including experimental tests and self-report measures. Participants also complete diagnostic assessments pre-intervention and 3 months post trial completion.
