A literature search identified 17 articles reporting data on 34 subjects who engaged in precursors to severe problem behavior, which we examined to identify topographical and functional characteristics. Unintelligible vocalization was the most common precursor to aggression (27%) and property destruction (29%), whereas self- or nondirected…

The purpose of the current study was to replicate the use of parents as therapists for experimental functional analyses of inappropriate mealtime behavior with multiple participants while measuring procedural integrity. Clear functions were identified, and high percentages of procedural integrity were obtained. (Contains 1 figure.)

It is argued that challenging behavior can be better understood if a correlational analysis (looking for correlations between behavior occurrence and other variables) is used in addition to functional analysis. A case example is provided of a man whose aggressive outbursts were negatively correlated with trips out of his unit. (Contains…
