Applied behavior analysis (ABA) is a therapy widely known as a treatment for individuals with autism spectrum disorder (ASD)–including PDD-NOS–or other developmental disabilities, such as Down syndrome and ADHD. It is the only researched and evidenced-based approach that has been shown to be highly successful in impacting and treating individuals with ASD. It is recognized as effective by a number of respected sources, including the U.S. Surgeon General, the American Academy of Pediatrics, and the National Institute of Mental Health. 

ABA treatment can be effective across all ages, from the first years of life to adulthood. Often the goals of treatment are to decrease negative behaviors such as aggression, tantrums, noncompliance and self-injury. ABA is also effective in increasing cognitive functioning, social interactions and executive functioning skills. And finally, it can improve essential life skills—including self-help skills, safety awareness and skills of daily living—in order to increase a child’s independence in both home and community settings.
