ABA is an area of expertise that can be seen as a branch of psychology. In Swedish it is called Tillämpad Beteendeanalys (TBA).
In ABA focus is on arranging an individual's environment to create positive changes in their life. This often means both optimizing the environment and teaching important skills the individual needs.

ABA is contextual
In behavior analysis behaviors are seen as a product of the context in which they occur. The most common way of analyzing the context is defining what happens before, and initiates, the behavior and what happens after the behavior. This way of structuring the analysis is sometimes called ABC and sometimes contingency analysis.
