Description:
In this episode of ABA Beyond the Data, we break down some of the most common functional analysis (FA) formats used in Applied Behavior Analysis—without getting lost in jargon. You’ll get a clear, practical overview of the history of FAs and why they’re considered the gold standard for identifying behavioral function. Then we walk through how standard analog (Iwata-style) FAs, brief FAs, precursor FAs, and interview-informed synthesized approaches (IISCA/PFA) work, what research supports them, and how to choose the most defensible option for your setting. Perfect for BCBAs who want to stay function-based and clinically practical.
