Why are functional analysis and FBA often used together?

Functional analysis and functional behavior assessment (FBA) are often used together because functional analysis systematically tests hypotheses regarding the function of a behavior. This method allows practitioners to identify the specific antecedents and consequences that influence problematic behaviors by manipulating environmental variables in controlled conditions. By conducting functional analyses, behavior analysts can observe how different variables affect the occurrence of behaviors, thus determining whether a behavior is maintained by attention, escape, access to tangibles, or sensory feedback.

Once the function of the behavior is established through this empirical testing, the findings can feed into the functional behavior assessment, which takes a broader perspective including direct observations and interviews to compile a detailed understanding of the behavior in natural contexts. This comprehensive approach ensures that interventions are tailored to the individual's unique behavioral needs, ultimately leading to more effective behavior management strategies. Therefore, the synergy between functional analysis and FBA is crucial in creating a robust framework for understanding and addressing behavioral issues.
