What are Antecedent Based Interventions?
As teachers we benefit from learning about Evidence Based Interventions (EBI) for students with autism. All teachers want to learn how to decrease the likelihood of challenging behaviors in the classroom. The only parts of the behavior chain we can influence or change are the antecedent and the consequence. Providing choices is a great Antecedent Based Intervention that teachers can use to prevent challenging behaviors.
Layman’s definition: Antecedent Based Intervention
When we focus on helping students with ASD in schools, we know that changing the classroom environment and how we present information has a big impact on their behavior. Changing the environment, and modifying things before behavior happens can improve behavior in students.
ABI as a preventative interventions to set the student up for success.
- Providing choices is an example of an Antecedent Based Intervention (ABI).
Choices may be more effective than using preferred reinforcers(Dunlap, et al. 1994)
Where can we provide choices in the school environment?
- Activities to be completed (math or reading)
- Materials to complete the task (pencil vs marker)
- location (table vs desk)
- Person to help them (teacher or a seat partner)
- A combination of them all
One way of providing choices is to give what’s called a “forced choice” by allowing students to have a small number of options that you as the teacher are ok with. Too many choices can become overwhelming for students with ASD. Providing two choices may be appropriate to start with.
