Functional analysis and treatment of aberrant behavior.

The authors wrote a narrative review about functional analysis. They looked at how to test why problem behavior happens. They suggested mixing two tools: watching in real life and running quick experiments.

The paper came out in 1991. It pulled together early work on functional analysis. It did not give new data. It gave a road map for clinicians.

The review found that using only one method can miss the real reason for behavior. Watching alone may guess wrong. Testing alone may feel too clinical.

The team said to start with descriptive notes, then run short test conditions. This combo gives clearer answers and saves time.

Melanson et al. (2023) now supersedes this paper. Their big scoping review of 1,333 cases shows FAs today use shorter sessions, more tangible conditions, and more autistic clients. The 1991 story is still correct, but the field has moved on.

Colombo et al. (2024) extends the idea to adults. Only 28 studies have tested FA with adults who have severe behavior. Their paper gives you a starter template for this age group.

Webb et al. (1999) extends the same combo to preschool. They showed that graphing descriptive data by suspected function first leads to faster, cleaner experimental tests in daycare rooms.

This 1991 paper gave us the playbook you still use: watch, then test. New reviews add speed, adult focus, and preschool tweaks, but the core two-step remains. Next time you assess, jot what you see, pick the top guess, and run one clear test condition. You will get a faster, surer function and a treatment that actually fits.
