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. A new study published in Frontiers in Pediatrics (2025) investigated how two common interventions, Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM), affect children with autism over a longer period.

What the Researchers Did

Researchers followed a group of young children diagnosed with autism for several years. Some children received ABA therapy, while others received ESDM. The researchers then tracked how the children developed in different areas, such as language, social skills, and adaptive behaviors (like dressing or feeding themselves). They wanted to see if there were different patterns of progress between the two groups over time.

What They Found

The study found that both ABA and ESDM were associated with positive changes in children's development over the years. Children in both groups showed improvements in their language skills, social interaction, and adaptive behaviors. The researchers noted that while both therapies led to progress, the rate and specific areas of improvement seemed to vary somewhat between the two groups. For example, one group might have shown faster gains in communication initially, while the other caught up or surpassed them in social skills later on. However, the study did not definitively conclude that one therapy was "better" than the other overall.

Why This Matters for Autism Families

This study is important because it looks at the long-term effects of these therapies. Many studies only look at changes over a shorter period. Knowing how children progress over several years gives us a better understanding of what to expect and how to best support their development. It also reinforces the idea that both ABA and ESDM can be valuable tools.

Practical Implications

Therapy Decisions: This research suggests that both ABA and ESDM can be effective. The "best" choice might depend on your child's individual needs, learning style, and your family's preferences. Talk to your doctor and therapists about which approach might be the best fit.
Realistic Expectations: Progress takes time. This study highlights the importance of long-term commitment to therapy and setting realistic expectations for your child's development.
Individualized Approach: The subtle differences in progress patterns between the groups reinforce the need for individualized therapy plans. Regular assessments and adjustments to the therapy approach are crucial to maximize your child's potential.

Important Considerations

It's important to remember that this is just one study. Like all research, it has limitations. For example, the sample size might have been relatively small, or there may have been other factors not accounted for that influenced the results. More research is always needed to confirm these findings and explore other aspects of these therapies.
