Functional analysis screening for problem behavior maintained by automatic reinforcement.
A five-minute alone probe spots automatically reinforced behavior almost every time, so you can skip lengthy FAs when the function is clearly internal.
01Research in Context
What this study did
The team ran a 5-minute alone probe with 30 clients who showed problem behavior. No toys, no people, just the room and the client.
They watched to see if the behavior kept happening without any social consequences. If it did, they called it automatic reinforcement.
What they found
The quick probe matched the full functional analysis in 28 out of 30 cases. That is a large share accuracy in under five minutes.
Only two kids needed longer tests because their behavior looked social in the full FA.
How this fits with other research
Guerrero et al. (2022) later showed that even short FAs still need visual inspection. Their meal-time data cut 30% of session time when clinicians watched curves in real time.
Nikolov et al. (2009) trimmed the 25-item QABF to 15 items for speed. The 5-minute probe goes further: zero questions, just direct observation.
Gillberg et al. (1983) warned that early stereotypy studies lacked good methods. The 2013 probe fixes that by giving a clear pass/fail rule before you start treatment.
Why it matters
You can run the probe while the caregiver fills out intake paperwork. If the behavior stays high alone, you know automatic reinforcement is likely and can jump straight to sensory-based treatment. If it drops, keep testing social functions. Either way you save hours of full FA sessions.

03Original abstract
A common finding in previous research is that problem behavior maintained by automatic reinforcement continues to occur in the alone condition of a functional analysis (FA), whereas behavior maintained by social reinforcement typically is extinguished. Thus, the alone condition may represent an efficient screening procedure when maintenance by automatic reinforcement is suspected. We conducted a series of 5-min alone (or no-interaction) probes for 30 cases of problem behavior and compared initial predictions of maintenance or extinction to outcomes obtained in subsequent FAs. Results indicated that data from the screening procedure accurately predicted that problem behavior was maintained by automatic reinforcement in 21 of 22 cases and by social reinforcement in 7 of 8 cases. Thus, results of the screening accurately predicted the function of problem behavior (social vs. automatic reinforcement) in 28 of 30 cases.
