I am a PhD student at the university of Queensland researching the
effects of siblings on the social and cognitive skills of children with
autism. I have an online survey about the play behaviour of children
with ASD which parents or caregivers can fill in.

Anyone with a child 4-12 with ASD can fill it in, they do not need to
participate in any future research.
