A Functional Behavior Assessment (FBA) is a systematic process used to understand why a behavior occurs. In ABA therapy, the FBA is the foundation for creating effective intervention plans because it identifies the purpose or function a behavior serves for the individual.

Why Behavior Has a Function

All behavior serves a purpose. The four main functions of behavior are:

• Attention: The behavior results in social interaction or attention from others
• Escape/Avoidance: The behavior allows the person to avoid a task, demand, or situation
• Access to tangibles: The behavior results in getting a desired item or activity
• Sensory stimulation: The behavior itself provides a sensory experience that is reinforcing

The FBA Process

An FBA involves gathering information through interviews with parents and caregivers, direct observation of the behavior in context, identifying patterns (when, where, with whom, and under what conditions the behavior occurs), and analyzing antecedents (what happens before) and consequences (what happens after).

How FBA Informs Treatment

Once the function is identified, the BCBA designs a behavior intervention plan that teaches an appropriate replacement behavior serving the same function. This approach is far more effective than simply trying to stop the behavior.
