At the heart of applied behavior analysis is the antecedent-behavior-consequence model. Antecedents refer to the events and conditions that take place right before a behavior occurs. These events and conditions contribute to the individual engaging in certain behaviors.
Most teachers would agree that it would be amazing indeed if we could prevent challenging behaviors from ever happening in the first place. While it might not be possible to prevent every challenging behavior, we can strive to decrease the likelihood of many such behaviors by analyzing the function of the behavior and then making changes to the environment or routine proactively. Such interventions that are put into place to help prevent the occurrence of interfering behaviors are referred to as antecedent-based interventions.
Common antecedent based interventions include, but are not limited to the following:
1) using highly preferred activities/items to increase interest level and motivation,
2) changing the schedule/routine based on student strengths and needs,
3) priming about upcoming events and/or changes,
4) offering choices,
5) altering the format of instruction, and
6) adjusting the environment so that learners with complex needs have access to sensory stimuli that serve the same function as the interfering behavior.
ABI strategies often are used in conjunction with other evidence-based practices, such as visual supports, social narratives, task analysis and more to maximize the positive impact. So let’s all keep our eyes on the “A” in ABA!
