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

As parents of children with autism, we're always looking for information about what therapies work best and what to expect in the long run. A new study published in Frontiers in Pediatrics (2025) looked at just that, comparing the long-term effects of two common therapies: Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM).

What the Researchers Studied

Researchers followed a group of children with autism over several years. All the children were receiving either ABA therapy or ESDM intervention. The study aimed to see how these therapies impacted the children's development in areas like communication, social skills, and adaptive behavior (things like daily living skills). They wanted to understand how the children changed over time, and whether there were noticeable differences between the two therapy groups.

What They Found (In Plain Language)

The study found that both ABA and ESDM were associated with positive changes in children with autism over the long term. Children in both groups showed improvements in their communication and social skills. The researchers also noted that gains in adaptive behavior were observed in both groups. While both therapies showed positive outcomes, the study didn't definitively say one therapy was significantly "better" than the other. The important takeaway is that *both* approaches can be helpful.

Why This Matters for Autism Families

This study is encouraging because it shows that early intervention with either ABA or ESDM can lead to lasting positive changes for children with autism. It reinforces the importance of early intervention and provides some reassurance that these therapies can make a real difference in your child's development. It also highlights that there isn't necessarily a single "best" therapy; what works well can vary from child to child.

Practical Implications

Therapy Decisions: This study can help inform discussions with your child's therapists and doctors about the best approach for your child. It's a reminder that both ABA and ESDM are evidence-based therapies.
School Planning: Understanding the potential benefits of these therapies can help you advocate for appropriate support and services in your child's school.
Daily Life: Knowing that these therapies can improve communication and adaptive skills can give you hope and motivation as you work with your child at home. Focus on reinforcing the skills they are learning in therapy in everyday situations.

Important Considerations

It's important to remember that this is just one study, and like all research, it has limitations. The sample size might have been relatively small, which means the findings might not apply to all children with autism. Also, every child is unique, and what works for one child may not work for another. This study provides valuable information, but it's crucial to consider your child's individual needs and preferences when making decisions about therapy.

Also, keep in mind that research is always evolving. More studies are needed to further explore the long-term effects of different therapies and to understand which approaches are most effective for different children.
