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 therapies work best. A new study published in Frontiers in Pediatrics (2025) offers some insights into the long-term effects of two popular interventions: Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM).

What the Researchers Studied

Researchers wanted to understand how children with autism changed over time after 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). The study compared the progress of children who received ABA to those who received ESDM.

What They Found

The study found that both ABA and ESDM were associated with positive changes in children's development over time. Children in both groups showed improvements in communication, social skills, and adaptive behavior. Importantly, the researchers noted that the *rate* and *type* of progress varied somewhat between the two groups. For example, one group might have shown faster gains in one area compared to the other. The study suggested that both therapies can be effective, but the specific benefits may differ from child to child.

Why This Matters for Autism Families

This research is important because it provides more information about the long-term impact of these therapies. Knowing that both ABA and ESDM can lead to positive changes can help families feel more confident in their therapy choices. It also highlights the importance of individualized treatment, as the best approach may depend on a child's specific needs and strengths.

Practical Implications

Therapy: This study reinforces the importance of early intervention. Both ABA and ESDM can be valuable tools, but it's crucial to work with therapists to tailor the approach to your child's unique profile.
School: Share this information with your child's school team. Understanding the potential benefits of different therapies can help them support your child's learning and development in the classroom.
Daily Life: Focus on creating a supportive and stimulating environment at home. Reinforce the skills your child is learning in therapy through everyday activities and interactions.

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. Additionally, the study only looked at ABA and ESDM; other therapies may also be effective. It is also important to note that ABA and ESDM are broad umbrellas and there are many different ways that they can be implemented.
