What You Need To Know About Setting Events in ABA

setting events

In ABA, setting events play a pivotal role as they can significantly influence the occurrence of target behavior. These factors, often overlooked, can be the key to understanding and supporting an individual’s behavior effectively.

This post explores the concept of setting events, their importance, how to identify and manipulate them, and the difference between setting events and triggers.

What are Setting Events?

A setting event is something that can happen long before challenging behavior begins that sets the stage for whether that behavior is more or less likely to occur. Whether it’s hunger, fatigue, or stress, these circumstances create an environment that sets the tone for certain behaviors to emerge. Past trauma can also be a setting event.

Without an awareness of these factors, it can be challenging to understand why someone is behaving a certain way. For instance, if a child comes to school without eating breakfast, he may be more likely to engage in challenging behavior when presented with a demand. If a student has a history of abuse, a simple touch could be a trigger.

As ABA professionals, it’s essential to recognize and identify these setting events to effectively support individuals with their social and emotional development. By doing so, we can use them to our advantage and promote positive behavior outcomes.

Common Types of Setting Events

Setting events can be both internal – like physical discomfort or emotional distress – and external – like a change in routine or a stressful home environment. Since these can be highly individualized, it’s essential to consider a learner’s unique context.

What’s the Importance of Accounting for Setting Events?

When a setting event is present, individuals may be more prone to engage in specific behaviors. This is why understanding and identifying setting events is so important — it allows us to anticipate and possibly prevent challenging behaviors before they arise.

By acknowledging setting events, ABA professionals can create a more supportive and enabling context that fosters positive changes in learners’ behavior. Acknowledgment of setting events encourages professionals to take a more comprehensive approach to behavior change that considers a wide range of factors that may be impacting individuals’ lives.

How to Identify Setting Events

Identifying setting events involves not only looking at the ABCs of behavior, but also asking the right questions. Careful observation and data collection are also crucial to identify setting events.

Consider various potential factors – such as time of day, presence of certain people, physical state, and emotional state. By carefully analyzing these setting events, professionals can develop effective interventions that address the root causes of challenging behaviors. Sometimes a simple change, like ensuring a child eats breakfast before school, can be a solution that eliminates the need for more complicated behavior change strategies.

Setting Events vs. Triggers

While setting events and triggers both influence behavior, they aren’t the same. A trigger, or antecedent, is an immediate event that directly leads to the occurrence of behavior.

On the other hand, a setting event doesn’t immediately lead to behavior, but instead establishes conditions that make certain behaviors more or less likely. For example, being hungry (setting event) might make a child more likely to scream when denied a snack (trigger).

Functional Behavior Assessment

While understanding setting events is valuable, sometimes behaviors are complex and require a Functional Behavior Assessment. This assessment helps to pinpoint the underlying factors contributing to a particular behavior, which is necessary for developing an effective intervention plan.

Setting Event Intervention Strategies

Once setting events are identified, intervention strategies can be developed. These could involve altering the environment, teaching new skills, or implementing reinforcement procedures.

For example, if a child often exhibits challenging behavior when hungry, an intervention might involve scheduling regular snack times to prevent hunger.

Setting events can be incredibly unique, based on the learner. However, just like other areas of therapy, there is a list of things that we can use as a jumping board. This may include parent coaching, teaching bedtime routines so the client gets enough sleep, or helping the family who may need financial assistance for food (and you can connect them with resources). The intervention may also be more focused on attention because the learner has to share parent time with a new sibling.

However, some setting events can’t be changed easily, like a chronic medical condition. Here, creativity is key. Developing personalized strategies that cater to an individual’s needs can make all the difference.

How to Monitor the Effectiveness of Setting Event Intervention Strategies

After interventions are implemented, it’s important to continue monitoring behavior to assess the effectiveness of the intervention. If the behavior doesn’t change as expected, the setting events may need to be reassessed.

This continuous monitoring and reevaluation ensures that the intervention remains effective over time and under changing circumstances.


Remember, setting events are simply one piece of the puzzle in understanding and shaping behavior. They should be considered in conjunction with other elements of the behavior-environment relation – such as antecedents and consequences. By comprehending and employing these factors effectively, professionals can create a more conducive environment for individuals to learn and exhibit adaptive behaviors.
