Antecedent-based Intervention (ABI)

Antecedent-based interventions can be used to decrease an identified interfering behavior and increase engagement by modifying the environment.

What Will I Learn?

The AFIRM model guides the learner through four lessons to facilitate:

  • Learning basic knowledge about antecedent-based intervention (ABI).
  • Applying ABI in activity based scenarios that promote real-world application.

The ABI module will take approximately 1.5 to 2 hours to complete. However, the module is broken into individual lessons to help guide your learning:

Lesson Time to Complete
A Case for ABI 10 minutes
Lesson 1: Basics of ABI 20 minutes
Lesson 2: Planning for ABI 25 minutes
Lesson 3: Using ABI 45 minutes
Lesson 4: Monitoring ABI 25 minutes
Applying ABI 10 minutes
