One of the strongest evidence-based practices is Applied Behavior Analysis
(ABA), which has over 20 years of research showing effectiveness for children
with autism.It is important to note that when I say “ABA”, I am not speaking
exclusively about Discrete Trial Training (DTT). Rather, I am talking about a
very large field of science which focus on using the principles of behavior
analysis to change behavior in order to make society a better place. This field
is not specific to autism, in fact, many parenting books, marriage books, and
addiction books focus on the principles of behavior analysis to help people. In
autism, DTT is one type of ABA that has shown effectiveness. Other types of ABA,
such as Pivotal Response Training (PRT) use more naturalistic teaching
strategies and have also shown effectiveness for remediating certain symptoms of
autism.
