Functional Analysis Decision-Making Considerations

Functional analysis (FA) is often considered an integral component of treating severe challenging behavior (e.g., aggression, self-injury). Given its essential nature, there are a growing number of publications aimed at supporting clinicians' understanding of FA design and methodological refinements for addressing barriers to implementation. The current paper builds on previous work by offering a guide for clinicians new to FA implementation. In particular, guidance is provided on <i>when</i> and <i>under what conditions</i> to include specific FA test conditions and how to select a given methodology for a case. In addition, we provide an in-depth discussion on best practices for safe and ethical FAs, regardless of the chosen setting, implementer, or methodology.
