New Study: How ABA and ESDM Therapies Impact Kids with Autism Over Time

As parents of children with autism, we're always looking for information about what works. A new study published in Frontiers in Pediatrics (2025) examined how two popular therapies, Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM), affect children with autism over a longer period. Let's break down what the researchers did and what they found.

What the Study Looked At

Researchers wanted to understand how children with autism changed over time when receiving either ABA therapy or ESDM intervention. They followed a group of children diagnosed with autism for several years, tracking their progress in different areas like communication, social skills, and adaptive behavior (things like self-care and daily living skills).

Specifically, they compared two groups: children who received ABA therapy and children who received ESDM intervention. They measured their progress at the beginning of the study and then again at several points over the following years.

What Did They Find?

The study found that both ABA and ESDM were associated with positive changes in children with autism over time. Both groups showed improvements in communication, social skills, and adaptive behavior. While both therapies showed positive results, the researchers also looked for differences between the two approaches. The study suggested that children in both groups improved at roughly the same rate, but this finding requires more research.

Why This Matters for Autism Families

This study is encouraging because it provides more evidence that both ABA and ESDM can be effective interventions for children with autism. It reinforces the importance of early intervention and highlights that different therapeutic approaches can lead to positive outcomes. For parents, this can be reassuring when making decisions about their child's care.

Practical Implications

Therapy: This study supports the use of both ABA and ESDM. It suggests that parents can work with therapists to choose the approach that best fits their child's needs and family preferences.
School: Understanding the benefits of these therapies can help parents advocate for appropriate support and services for their child in the school setting.
Daily Life: Improvements in communication, social skills, and adaptive behavior can significantly impact a child's ability to participate in daily activities and build relationships.

Important Considerations

It's important to remember that this is just one study, and more research is always needed. The sample size was relatively small, which means the findings might not apply to all children with autism. Also, every child is different, and what works for one child may not work for another. It is important to discuss treatment options with your child's care team and make informed decisions based on their individual needs and progress.

Additionally, this study, like many, relies on standardized assessments to measure progress. While these assessments are valuable, they don't always capture the full picture of a child's development and unique strengths.
