Can ABA Therapy Make Autism Worse? Facts vs Myths

February 18, 2026

No, ABA therapy does not make autism worse when done right. Modern ABA focuses on building skills through positive reinforcement, not punishment. Done poorly, it can cause stress or masking, but evidence shows benefits outweigh risks for many kids.



ABA therapy uses behavior principles to teach skills like communication and social interaction. A 2018 study linked harsh early ABA to PTSD symptoms in some autistic adults. But today's best practices avoid that, prioritizing fun and choice-based learning.


Research from the National Autism Center calls ABA evidence-based for skill gains and reducing harmful behaviors. No studies show it worsens core autism traits like sensory needs—it targets daily living skills instead.


Real-World Proof

In Lovaas's 1987 study, kids got 40 hours weekly of ABA. Many lost their autism diagnosis and joined regular classes, with gains holding years later. A PMC review notes modern ABA evolved: less rigid, more natural play like Pivotal Response Training.


One case: A nonverbal child learned to communicate via pictures, cutting tantrums by 80% without force. Parents report happier, more independent kids.


Key Risks to Watch

Harsh ABA might push masking, leading to burnout or low self-esteem. Always pick board-certified therapists (BCBAs) who use reinforcement first.
