DINO RCT - Treating Anxiety in Children With Autism

The purpose of this study is to examine the feasibility and preliminary efficacy of a new treatment that targets both anxiety and IU, i.e., DINOSAUR, in young autistic children with varying cognitive and language levels. To accomplish this goal, we will investigate if DINOSAUR is a feasible intervention for families of young autistic children. We will also investigate if DINOSAUR is superior to an active control condition in reducing anxiety and IU. A third, exploratory goal is to understand how children's language and cognitive level affect their response to anxiety treatment. Seventy children, 4-6 years of age with autism and clinically significant anxiety, and their parents will be randomly assigned to receive either DINOSAUR or the active control (35 in each group) over 14 weeks via telehealth. Within each condition, children will be stratified based on cognitive level. Anxiety and IU will be assessed following treatment and at 4-month follow-up.
