Functional assessment of challenging behavior: toward a strategy for applied settings.

Kleinert et al. (2007) wrote a story-style review. They looked at how far functional assessment had come. They talked about what works, what breaks, and how to make it clinic-friendly.

The paper covers kids and adults with developmental delays. It mixes experimental functional analyses with quick checklists. The goal was to show how to fit good assessment into busy day-to-day work.

The review says you can shorten tests and still learn the why behind behavior. Simple checklists and brief analog sessions give enough detail to plan treatment.

They also warn that even the best tools flop if staff lack time or training. Real-world use needs both solid method and doable steps.

Melanson et al. (2023) now supersedes this view. Their giant 2023 map of 1,333 outcomes shows shorter sessions, tangible tests, and more autism cases are the new normal.

Colombo et al. (2024) also supersedes L et al. They found only 28 adult studies across 25 years. Their tighter 2024 filter gives clearer starting scripts for adult services.

Amador et al. (2024) extends the idea. They show trial-based FAs fit right into classrooms. One-minute probes woven into lessons keep kids in class while you find the function.

You no longer need a long lab session to find a function. Use five-minute trial-based probes or brief IISCA formats. Start with the tools Melanson shows are common now: tangible, attention, escape, alone. If you serve adults, lift the step-by-step plans Colombo pulled from 28 studies. Pick the format that matches your setting, not the other way around.
