The Role of Adverse Childhood Experience in the Relationship Between Autism Severity and Early Intervention and Special Education Plan.

Stein Elger et al. (2025) · Journal of autism and developmental disorders 2025
★ The Verdict

Trauma can erase the usual link between severe autism and getting school help, so mild kids with high ACEs need extra advocacy.

✓ Read this if BCBAs writing or reviewing IEPs and early-intervention plans for children with autism in public schools or clinic-to-school transition teams.

01Research in Context

01

What this study did

Stein Elger et al. (2025) asked a simple question: does autism severity still predict who gets an early-intervention or special-education plan when kids also have adverse childhood experiences (ACEs)?

They looked at children with autism and counted how many ACEs each child had. Then they checked who had an active school or early-intervention plan.

02

What they found

Kids with moderate or severe autism were more likely to have a plan—unless they also had a pile-up of ACEs.

As ACE count rose, the link between severe autism and getting services faded. Mild-autism kids with high ACEs were the most likely to slip through the cracks.

03

How this fits with other research

Hartwell et al. (2024) saw the same pattern in a giant national sample: more ACEs meant fewer school supports and worse grades for autistic kids. Rafaella’s 2025 study zooms in and shows why—trauma blunts the signal that severity usually sends to teams.

Jackson et al. (2025) add attendance and grade progression to the story. They found each extra ACE hurts these outcomes even after accounting for anxiety or depression. Together the three papers form a chain: ACEs block services, and missing services then widen the achievement gap.

Stephens et al. (2018) already showed high-ACE families wait longer for both diagnosis and therapy. Rafaella’s finding is the next logical step: by the time these kids reach school, their trauma history can hide their need for help.

Why it matters

If you only look at autism severity, you can miss kids whose trauma masks their needs. Add a quick ACE screener to your intake. When mild symptoms sit beside high ACEs, push hard for an evaluation or plan—don’t wait for “more obvious” signs.

03Original abstract

The purpose of this study is to examine the association between autism spectrum disorder (ASD) severity and having a special education or early intervention plan and the impact of adverse childhood experiences (ACEs) on this association. This study used the 2020-2021 National Survey of Children's Health (NSCH) and included 2,537 children aged 3-17 years old who currently have ASD. Multivariable logistic regression, controlling for demographic and family characteristics and health status, was used to explore the association between autism severity and having an early intervention plan. The analysis was stratified by the number of ACEs to explore their role in the association. Children with moderate or severe ASD were more likely to have a special education or early intervention plan than those with mild ASD in the crude and adjusted models. This association continued to be true for children who experienced 1 ACE (aOR: 2.28, 95%CI: 1.09-4.77) but not true for those who experienced no ACEs (aOR: 1.16, 95%CI: 0.70-1.94) and 2 or more ACEs (aOR: 1.84, 95%CI: 0.92-3.69). Results demonstrate that children with moderate or severe autism were more likely to receive early intervention or special education. This association changed depending on the number of ACEs experiences.
