What is the purpose of a Functional Behavior Assessment (FBA)?

The purpose of a Functional Behavior Assessment (FBA) is to identify the function of a behavior. This process involves gathering information and evidence about a specific behavior in order to understand why an individual may be engaging in that behavior. By analyzing patterns and contexts in which the behavior occurs, practitioners can discern potential triggers, antecedents, and consequences that maintain the behavior.

Identifying the function is crucial because it allows for the development of targeted interventions that address the root causes of the behavior rather than merely attempting to modify the behavior itself. When the function is understood—whether it is for gaining attention, escaping a situation, accessing materials, or self-stimulation—strategies can be devised to teach alternative, more appropriate behaviors that serve the same function for the individual. This functional approach ensures interventions are relevant and effective.

While assessing cognitive abilities, evaluating academic performance, and analyzing social interactions are important aspects of understanding a person's overall functioning, they are not the primary goals of an FBA. The focus of an FBA is specifically on understanding behaviors in terms of their functions to inform effective behavioral interventions.
