New research in Autism looked at 34,000+ autistic youth.
Those who received ABA had:
📊 30% higher odds of mental health hospitalization
📊 32% higher rates of hospitalization
These are not small differences.
No differences were found for PTSD or suicidality diagnoses, but the authors note:
👉 PTSD is often underdiagnosed in autistic youth
👉 The most serious impacts may not show up until later in life
This study doesn’t prove causation. But it does show this:
👉 The group receiving one of the most widely recommended interventions was more likely to be hospitalized for mental health reasons.
For years, autistic adults have said ABA caused harm. Now we have large-scale data showing patterns that raise the same concerns.
At some point, we have to ask:
What are we actually doing to autistic youth in the name of “support”?
While these findings are associational, they highlight the need for robust, long-term research on the safety of ABA.
The authors also call for a shift away from focusing primarily on observable behavior and toward trauma-informed, neurodiversity-affirming approaches.

This study aims to investigate the association between applied behavior analysis therapy and post-traumatic stress disorder, suicidality, mental health hospitalizatio...
