Imagine a therapy that can dramatically change the trajectory of a child's life, a claim powerfully supported by data showing that nearly half of children receiving intensive ABA therapy achieve typical educational and intellectual functioning, sustained for over a decade.
Key Takeaways
- In a 2019 meta-analysis of 14 studies involving 555 participants, intensive ABA therapy (over 20 hours/week) resulted in a standardized mean difference (SMD) of 0.55 for intellectual functioning improvements in children with autism spectrum disorder (ASD).
