Applied Behaviour Analysis (ABA) is a framework for the scientific study of the relationship between environment and behavior. ABA attempts to improve socially significant behaviors through behavior principles of manipulations to the antecedent and consequences responsible for a behavior. ABA by itself is not a kind of therapy or intervention. Rather, it is a set of principles by which a behaviour modification program is based. Many principles of ABA originated from the theories of B. F. Skinner then applied by Ole Ivar Lovaas. In 1968, Baer, Wolf, and Risley defined the seven elements which characterize the field of Applied Behaviour Analysis. An ABA-based program or study: applied, behavioural, analytic, technological, conceptually systematic, effective, generality.

Under the “umbrella” of ABA, there are several interventions and therapies that treat autism. Examples include: Lovaas/UCLA Model, Verbal Behaviour, Discrete-Trial Training, Pivotal Response Training, Natural Environment Teaching, Incidental Teaching, Intensive Behavioural Intervention, and Picture-Exchange Communication System.

  • Well-researched
  • Evidence-based practice
  • Showed significant improvements in IQ, language skills, and academic performance
  • Improves developmental delays




Research shows that children who begin ABA-based programs have over an 80% chance of improvement. These children benefit from ABA as it helps them learn to enjoy all things life can offer.
