What is a "functional behavior assessment" (FBA)?

A functional behavior assessment (FBA) is a systematic process used to identify the underlying causes of specific behaviors exhibited by individuals, particularly in educational or clinical settings. By examining factors such as antecedents (triggers), behaviors, and consequences, the FBA seeks to understand not just what the behavior is, but why it is occurring. This understanding can then guide the development of effective interventions and strategies aimed at changing or managing the behavior, making it a critical component in behavior analysis.

The other options do not accurately reflect the purpose of an FBA. A survey of teacher opinions about behavior lacks the systematic approach needed to analyze behaviors deeply, whereas a questionnaire evaluating classroom dynamics may provide insight into interactions but does not pinpoint the specific function of an individual's behavior. Likewise, a method for direct observation without analysis falls short of the comprehensive evaluation necessary for understanding the causes and functions of behaviors. Thus, option B captures the essence of what an FBA entails, emphasizing its goal of identifying the reasons behind a behavior.
