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 that can help us make the best decisions for our kids. A new study published in Frontiers in Pediatrics (2025) sheds some light on how two common therapies, Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM), can affect children with autism over several years.

What the Researchers Studied

Researchers wanted to understand how children with autism changed over time after receiving either ABA or ESDM therapy. They followed a group of children for several years, regularly assessing their language skills, social abilities, and adaptive behaviors (like self-care and daily living skills). The study compared the progress of children receiving ABA to those receiving ESDM.

What They Found (In Plain Language)

The study found that both ABA and ESDM were associated with positive changes in children's development over time. Specifically, children in both groups showed improvements in language and adaptive behaviors. The researchers noted that the amount of progress varied between individuals, which isn't surprising, as every child is unique. The study did *not* find significant differences in outcomes *between* the ABA and ESDM groups. In other words, both therapies appeared to be similarly effective in promoting development over the long term.

Why This Matters for Autism Families

This study is important because it provides evidence that both ABA and ESDM can be effective therapies for children with autism over the long haul. Knowing that both approaches can lead to positive changes can empower parents to make informed decisions about which therapy (or combination of therapies) is the best fit for their child's individual needs and their family's values.

Practical Implications

Therapy: This research reinforces the importance of early intervention. Whether you choose ABA, ESDM, or another evidence-based therapy, starting early can make a big difference.
School: Understanding the potential benefits of these therapies can help you advocate for your child's needs in school. You can work with the school team to incorporate strategies from ABA or ESDM into your child's IEP (Individualized Education Program).
Daily Life: The study highlights the importance of focusing on language development and adaptive skills. You can work on these skills at home through play, daily routines, and social activities.

Important Considerations (Limitations)

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

Also, it's important to remember that "ABA" and "ESDM" are broad terms. The specific techniques used within these therapies can vary widely. The effectiveness of any therapy depends on the individual child, the therapist's expertise, and the consistency of implementation.
