ABA is Applied Behavior Analysis. Applied is the principal that is used to change socially significant behavior. Behavior is an observable & measurable act that is the focus of the intervention. Analysis is the measurement of behavior to determine functional and replicable relationships between intervention and outcome. ABA is based on scientific methods and is founded on seven core dimensions (Baer, Wolf, Risley, 1968).
ABA is the most researched, evidence based and comprehensive approach for treatment of autism spectrum disorder. According to National Standards Project published by the National Autism Center, two thirds of established interventions for autism are based on behavior interventions.
The earlier a child gets ABA intervention the better. However, it is never too late to teach children and adults the behavior skills they need to function and live a good quality of life.
