ABC behavior data sheet

ABC data is a recording of what is happening before, during and after the behavior. It is also referred to as narrative recording or three-term contingency. When taking ABC data, it is helpful to be as detailed as possible, so that there is little room for subjective interpretation.

In applied behavior analysis, ABC data is referred to as the three step contingency. Each step has a relationship to one another and work together to either maintain or change a behavior.

The collected ABC data can help create an image of the potential function of behavior (escape, access to something tangible, attention, automatic reinforcement). This is an important part of creating an effective intervention to increase appropriate skills and reduce behaviors that are unable to adapt.
