Which of the following best describes a Functional Behavioral Assessment (FBA)?

A Functional Behavioral Assessment (FBA) is a comprehensive and systematic approach used to identify the underlying causes of challenging behaviors exhibited by an individual. It involves collecting data through various methods such as interviews, observations, and direct data collection to gather information about the antecedents, behaviors, and consequences related to the individual’s actions. This detailed evaluation process enables practitioners to ascertain why behaviors occur and how they can be modified or replaced with more appropriate actions.

In contrast, the other options represent different forms of assessment that do not encompass the extensive analysis characteristic of an FBA. For instance, testing learning preferences pertains to understanding how a person learns best, which is distinct from assessing behavior functions. Occasional observations of behavior and snapshot assessments focus on brief or limited views of behavior or skills rather than an in-depth analysis of patterns and triggers. Therefore, option B stands out as it accurately captures the essence and depth of the FBA process.
