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 we can expect long-term. A new study published in Frontiers in Pediatrics (2025) sheds some light on this, comparing the progress of children receiving Applied Behavior Analysis (ABA) therapy and those receiving Early Start Denver Model (ESDM) intervention over several years.

What the Researchers Studied

Researchers wanted to understand how children with autism change over time when receiving either ABA or ESDM therapy. They followed a group of children for several years, regularly assessing their language skills, social interaction abilities, and adaptive behaviors (like daily living skills). The study compared the progress of children in each therapy group to see if one approach led to different outcomes over the long haul.

What They Found (in Plain Language)

The study found that both ABA and ESDM therapies were associated with improvements in children's skills over time. Kids in both groups showed gains in language, social interaction, and adaptive behaviors. While the study didn't find a huge difference between the two therapies in terms of overall progress, there were some subtle differences. For example, the researchers noted that children in the ESDM group sometimes showed earlier gains in social communication, while the ABA group sometimes demonstrated stronger gains in specific adaptive skills. However, these differences were not consistent across all children or all areas of development.

Why This Matters for Autism Families

This research is important because it gives us a better understanding of the potential long-term benefits of ABA and ESDM. Knowing that both therapies can lead to improvements can be reassuring. It also highlights that the "best" therapy might depend on your child's individual needs and strengths. This study reinforces the importance of working with professionals to create an individualized treatment plan.

Practical Implications

Therapy Decisions: This study can help guide conversations with your child's therapists and doctors about which therapy approach might be the best fit.
School Planning: Understanding the potential benefits of different therapies can help you advocate for appropriate supports and services in your child's school.
Daily Life: Knowing that both ABA and ESDM can improve adaptive behaviors can motivate you to focus on teaching your child important daily living skills at home.

Important Caveats

It's important to remember that this is just one study, and like all research, it has limitations. The sample size was relatively small, meaning the findings might not apply to all children with autism. Also, the study only looked at ABA and ESDM, and there are many other effective therapies for autism. More research is always needed to confirm these findings and explore the long-term effects of different interventions.
