What is the primary reason for conducting a functional behavior assessment?

The primary purpose of conducting a functional behavior assessment (FBA) is to identify the function of behavior. Understanding the function behind an individual's behavior is crucial because it allows practitioners to determine what the behavior is communicating or what needs it is trying to fulfill. By pinpointing the underlying reasons for the behavior—such as gaining attention, escaping a task, seeking sensory input, or obtaining tangible rewards—interventions can be tailored to address these specific needs.

This targeted approach is more effective than simply addressing behaviors in isolation or collecting broad data without focusing on purpose. Once the function is established, appropriate strategies can be developed to modify the behavior or teach replacement behaviors that meet the same need in a more acceptable way. This foundational knowledge is what leads to more meaningful and lasting change in behavior, as it directly addresses the root cause rather than merely responding to the behavior itself.

Other options, while they may seem relevant, do not capture the primary aim of an FBA. Gathering data on all behaviors can be overwhelming and may not focus on the most critical aspects. Developing new interventions typically follows the FBA process but is not the main goal of conducting one. Observing peer interactions can provide useful context, yet it does not address the assessment's overall aim of
