The effects of conducting a functional analysis on problem behavior in other settings.

The team ran standard functional analyses on children with problem behavior. They then watched the same kids in other places to see if the FA made behavior better or worse outside the test room.

Each child got the usual FA sessions: alone, attention, demand, and toy play. Staff tracked problem behavior during these sessions and also during recess, snack, and free play later in the day.

Some kids acted out more in the hallway after the FA. Other kids calmed down. The rest stayed the same. No clear pattern showed up across the group.

In short, the FA itself did not predictably spill over into everyday life. The effect was different for each child.

Lang et al. (2008) already showed that FA results can change between clinic and classroom. The 2012 study adds that even when the FA stays in one room, behavior elsewhere can still shift in any direction.

Henry et al. (2021) later built a staged brief-to-extended FA model that gives clearer answers faster. Their 100% conclusive results move the field past the mixed findings seen here.

Nesselrode et al. (2022) reviewed schools and found brief and trial-based FAs are now common. These shorter forms lower the chance of long spill-over windows, a practical fix for the idiosyncratic effects A et al. flagged.

You can stop worrying that every FA will blow up behavior in other places. Still, watch the child outside the session. If problem acts rise, shorten the FA or switch to a brief format. If behavior drops, great—keep going. Either way, collect a few quick probe data points after each FA day so you catch the drift early.
