Functional Behavior Assessment (FBA) is a systematic process in which challenging behaviors are analyzed to help determine the purpose behind them before developing an intervention. It is a problem-solving approach in which a clinician works with an individual and each of his or her support staff to identify a variety of variables that may influence the presence of a specific behavior or behaviors. FBA is an individualized assessment but requires a team effort. It is considered to be evidence-based and the current gold standard of approaching challenging behaviors in people with ASD, and links with positive behavior support practices to ensure that interventions are individualized, based on the hypothesized etiology/cause (function) of behavior.
