Antecedent influences on behavior disorders.

Smith et al. (1997) wrote a narrative review. They asked researchers to look at what happens right before a behavior disorder occurs.

The paper sorts these triggers into two kinds: discriminative stimuli and establishing operations. It uses basic ABA language, not medical labels.

The review does not give new numbers. It gives a map. The map shows how room setup, task difficulty, or recent attention can set off problem behavior.

The authors say most studies still focus on what happens after behavior. They want more work on what happens first.

Simó-Pinatella et al. (2013) extends this idea. They tested adults with ID and found social and cultural antecedents predict most challenging behavior. G et al. talked theory; David et al. gave data.

Farrant et al. (1998) used the same narrative style but looked at behavioral history instead of immediate triggers. Both papers say "past matters," just different parts of the past.

Duker et al. (1991) reviews functional analysis. Their paper pairs well: G et al. tells you what to watch before behavior; C et al. tells you how to test it.

Next time you write an FBA, list the MOs and SDs first. Ask: What task, person, or object was present right before the hit? Then test if changing that item removes the hit. This front-loads your intervention and can cut problem behavior before it starts.
