New Study: How Do 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) investigated how two common early intervention approaches, Applied Behavior Analysis (ABA) and the Early Start Denver Model (ESDM), impact children with autism spectrum disorder (ASD) over several years.

What Did the Researchers Study?

Researchers wanted to understand how children with autism change over time when receiving either ABA therapy or ESDM intervention. They followed a group of young children diagnosed with ASD who were receiving one of these therapies. The researchers looked at various aspects of the children's development, including:

Cognitive abilities: Thinking, learning, and problem-solving skills.
Language skills: Understanding and using spoken language.
Adaptive behavior: Skills needed for daily living, like self-care and social interaction.

The study tracked these skills over a period of several years to see how the children progressed with each therapy.

What Did They Find? (In Plain Language!)

The study found that both ABA and ESDM were associated with improvements in cognitive abilities, language skills, and adaptive behavior over time. This means that, on average, children in both therapy groups showed positive developmental progress. The researchers also noted that the amount of progress varied from child to child, which isn't surprising since every child is unique!

Importantly, the study did not find a significant difference in outcomes between the two therapy groups. In other words, children receiving ABA and those receiving ESDM showed similar levels of improvement across the areas studied.

Why Does This Matter for Autism Families?

This study offers some reassuring news for parents. It suggests that both ABA and ESDM can be effective interventions for children with autism. Knowing that there are multiple paths to progress can empower families to choose the therapy approach that best fits their child's needs, learning style, and family values. It highlights the importance of early intervention in general.

Practical Implications

Therapy Decisions: This research reinforces the idea that both ABA and ESDM are valuable options. When choosing a therapy, consider your child's individual strengths and challenges, as well as your family's preferences. Talk to professionals experienced in both approaches.
School Planning: Share this information with your child's school team. Understanding the potential benefits of both ABA and ESDM can help inform individualized education program (IEP) goals and strategies.
Daily Life: The focus on adaptive behavior highlights the importance of incorporating daily living skills into your child's routine. Work with therapists to identify specific skills to target at home, such as dressing, eating, and social interaction.

Important Considerations (Limitations of the Study)

It's important to remember that this is just one study, and like all research, it has limitations. The study likely included a relatively small number of participants, which means the findings might not apply to all children with autism. More research with larger and more diverse groups is always needed to confirm these results. Also, the study only looked at ABA and ESDM; other effective therapies exist.
