What is the first step in conducting a functional behavior assessment (FBA)?

The first step in conducting a functional behavior assessment (FBA) is to define the behavior. Clearly identifying and articulating the specific behavior of concern is essential because it sets the foundation for the entire assessment process. If the behavior is not well-defined, any subsequent steps—such as gathering information or analyzing data—will lack focus and may lead to inaccurate conclusions about the function of the behavior.

Defining the behavior involves using clear, observable, and measurable terms. This precise definition helps ensure all observers are on the same page and that the assessment accurately targets the behavior that needs to be modified. Once the behavior is defined, practitioners can then gather information and analyze data to determine the causes and functions of that behavior, ultimately leading to the development of effective intervention strategies.
