Antecedent-Behavior-Consequence Analyses

Antecedent-behavior-consequence (A-B-C) analyses are used to determine patterns in the occurrence of the antecedents, behaviors, and consequences that relate to the problem behavior. A-B-C analyses are often quite useful in developing initial hypotheses or summary statements of the child’s challenging behavior.

In addition to A-B-C analyses, the team may use a data collection card to collect A-B-C information. Carr and his colleagues (1994) suggest using context cards - cards used to describe the general context, interpersonal context, behavior problem, and social reaction regarding the child's challenging behavior.

Context cards are helpful because they prompt the observer to consider the broader context that may relate to problem behavior. In addition, the collection of data on a car facilitates the easy analysis of the data. Once there are several completed cards, the observer or team member can sort the cards by perceived function of the behavior. This method of segmenting observations and collecting multiple observations is very easy for team members to use and understand.
