For the second year, the US Government reports that ABA does not work. In the biggest study on autism consisting of 15,928 individuals with autism, the government looked at improvements after 12 and 18 months of ABA services and concluded that “the changes are small and may not be clinically significant.”

The report also looked at the relationship between the change in baseline and the number of hours of rendered ABA services. “For the East region, the trend line indicates that beneficiary scores worsened with more hours of ABA services. In the West region, there is no statistically significant correlation between the total number of direct hours rendered and outcome measure scores.”

The report continues, “There does not appear to be a correlation between outcome measures and the number of hours rendered. In other words, the number of hours rendered does not appear to impact outcomes. If the amount of direct ABA services was correlated with improvement, the trend line would demonstrate a statistically significant negative slope.”

The failure of the Functional Behavior Assessment also leads to misinformed treatment of Self Injurious Behaviors in autism. https://www.tandfonline.com/doi/full/10.1080/23311908.2019.1682766
