ABA: Facts and Statistics

  • In a 1987 study, Ivar O. Lovaas compared the results of a control group to that of young children with autism who received ABA therapy. Results indicated that with 40 hours of ABA therapy a week for several years 90% of participants substantially improved, some even to normal intellectual functioning compared to the control group.
  • An article by Hagopian and Boelter (2012) investigated the scientific support for ABA. The following organizations have classified ABA therapy to be a highly effective treatment for individuals with autism and mental retardation:
  1. American Association on Intellectual and Developmental Disabilities
  2. National Institute of Mental Health
  3. Association for Science in Autism Treatment
  4. Autism Speaks
  5. Organization for Autism Research
