ABC Data: The Key to Understanding Behavior

Professionals in the field of ABA often refer to ABC data as the 3-term contingency. The 3 terms include the antecedent (A), the behavior (B) and the consequence (C). Each component contributes to a greater understanding of why behavior continues. You then use this information to create a Behavior Intervention Plan (BIP) or to develop a plan for skill acquisition.
