DINO RCT - Treating Anxiety in Children With Autism

April 22, 2026 updated by: Amy Keefer, Hugo W. Moser Research Institute at Kennedy Krieger, Inc.

Treating Anxiety in Young Children With Autism

Anxiety is prevalent in young children, under 7 years of age, with autism. Yet, few studies have examined anxiety interventions for this age range, and only one anxiety treatment study has included young children with cognitive and language delays. Anxiety treatment models utilizing cognitive-behavioral therapy (CBT), adapted for children with autism, are empirically supported in school-age autistic children. Further, preliminary evidence suggests CBT approaches may reduce intolerance of uncertainty (IU), a mechanistic construct that may contribute to the maintenance of anxiety in autistic children. This study seeks to address the existing gap in anxiety treatment by examining the feasibility and preliminary efficacy of a novel, telehealth CBT intervention, DINO Strategies for Anxiety and intolerance of Uncertainty Reduction (DINOSAUR), which targets both anxiety and IU in young autistic children.

Study Overview

Detailed Description

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.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Treatment
Parent-child dyads will receive DINOSAUR, a group-based cognitive-behavioral therapy (CBT) intervention, adapted for young children and delivered via telehealth. This 14 week intervention teaches parents and children strategies to reduce anxiety and intolerance of uncertainty, an underlying construct of anxiety.
This intervention aims to treat intolerance of uncertainty and anxiety in young autistic children.
Active Comparator: Active Control
Parents in the active control condition will participate in three psychoeducational groups focused on presenting information regarding anxiety prevalence, differentiating anxiety from autism, and anxiety triggers. These groups will be delivered via telehealth across a 14-week period.
This intervention provides psychoeducation regarding anxiety and autism.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in child anxiety diagnostic status on Anxiety Disorders Interview Schedule, Autism Spectrum Disorder Addendum (ADIS-ASA)
Time Frame: Before and after 14-week treatment (baseline to post-treatment)
The Anxiety Disorders Interview Schedule (ADIS) is a semi-structured parent interview assessing the severity of anxiety disorders and its presentation in individuals with autism.
Before and after 14-week treatment (baseline to post-treatment)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in anxiety severity on Child Behavior Checklist
Time Frame: Before and after 14-week treatment (baseline to post-treatment) and at 4 month follow-up
An established 99-item parent and teacher report of broad psychopathology; T scores range from 20 to 100; Syndrome scales: T-scores over 65 indicate clinically significant symptoms.
Before and after 14-week treatment (baseline to post-treatment) and at 4 month follow-up
Change in child's intolerance of uncertainty on Response to Uncertainty and Low Environmental Stability Scale
Time Frame: Before and after 14-week treatment (baseline to post-treatment) and at 4 month follow-up
Parent and teacher report scale measuring response to uncertainty and low environmental structure; scores range from 1 to 5; higher scores indicate higher intolerance of uncertainty.
Before and after 14-week treatment (baseline to post-treatment) and at 4 month follow-up
Change on parental accommodating behaviors on Family Accommodation Scale following 14-week active control and 14-week intervention.
Time Frame: Before and after 14-week treatment (baseline to post-treatment) and at 4 month follow-up
Assesses parental accommodating behaviors; scores range from 0 to 36; higher scores indicate higher parental accommodation.
Before and after 14-week treatment (baseline to post-treatment) and at 4 month follow-up
