Antecedent events as predictive variables for behavioral function.

Simó-Pinatella et al. (2013) asked which everyday events best predict why challenging behavior happens in people with intellectual disability. They sorted antecedents into three buckets: social (attention, demands), cultural (routines, rituals), and biological (pain, fatigue).

The team reviewed 30 prior functional assessments and scored each antecedent category. They then looked for the link between these events and the behavior’s true function—escape, attention, or automatic reinforcement.

Social and cultural events predicted nearly all behaviors maintained by escape or attention. Biological events only showed up when the behavior served automatic reinforcement—like head-banging that produces its own sensory payoff.

In plain words: if the behavior is about getting or avoiding people, start by asking what social or routine events just happened. If it is self-stimulatory, check for pain or fatigue last.

Aman et al. (1993) saw functional assessment use rise through the 1980s, yet intrusive restraints for aggression stayed common. David’s 2013 map gives today’s BCBAs a faster route: look at social triggers first and you may avoid those heavy procedures.

Hoffmann et al. (2018) took the next step. They treated the early, mild “precursor” behaviors that David’s social antecedents often spark. By intervening at the precursor, they kept severe problem behavior at zero for three preschoolers—proof that early social-focused FBA works in real time.

Poppes et al. (2016) seems to clash: staff still blame biology most often. The gap is method, not truth. David used data; P used staff surveys. The lesson: our gut points to biology, but the data point to social events—so trust your FBA, not your first hunch.

You can shave minutes off every FBA interview. Ask about attention shifts, task demands, and routine changes before you ask about sleep, pain, or meds. This small flip matches the science and gets you to a working intervention faster.
