Applied behavior analysis (ABA) is the scientific process of analyzing and systematically altering environmental contingencies to increase skills and decrease problem behaviors. It is much more comprehensive than just a treatment technique or intervention, and is often discussed or presented in a misleading way in the popular media. Behavior analytic principles have been utilized to assess and treat almost every imaginable human behavior deficit and excess. The science of ABA utilizes the most effective and evidence-based methods to change behaviors in a safe, efficient, and developmentally appropriate manner.
