Purpose: After the diagnosis of Autism Spectrum Disorder (ASD), misconceptions arise creating a division of whether he or she should receive services creating the question: is ABA therapy effective. The question stems from a lack of parental or caregiver knowledge and accessibility, which are dependent on whether or not it was a late diagnosis. In this study, I identify the advantages of children who receive early intervention, which highlights how they excel in comparison to children who do not have access to services in the United States and developing countries. The comparison of both groups will show how these services can help children get closer to the desired milestone for their age. This research is informative to parents of Autistic children and interventionists as it provides age to milestone correlation in comparison to children who receive no services. The targeted group ranges up to pre-adolescent, a crucial age that parents have trouble with as they transition into adolescence means: puberty and active citizenship. This essay aims to help understand the importance of ABA therapy and the need to help those who lack the knowledge to know what autism is.

Methods: Academic journals of cross-sectional studies were based on children between the ages of 0-10 years old with groups of children to receive ABA, a form of early intervention in comparison to a lack of services. Children were tracked from the point they started therapy and correlation to milestones with age. The data from past investigations used age groups in the success of ABA therapy.

Results: Evidence shows culture, socioeconomic status, age, accessibility, and knowledge about autism plays a strong role in whether or not a child receives early intervention. It has been scientifically proven that Applied Behavior Analysis (ABA) therapy is effectively positive for autistic children and their caregivers. Although there is scientific evidence of its positive effects regions who do not know the symptoms of autism will have the greatest risk.
