title: Food selectivity and problem behavior in children with developmental disabilities. Analysis and intervention.
abstract: Excessive food selectivity typifies some children with developmental disabilities. We conducted functional analyses to determine the controlling variables for problem behavior that accompanied food selectivity and analyzed the role of establishing operations in ameliorating food selectivity. Specifically, we studied the differential effects on intervention efficacy of an individual's having or not having access to preferred food items prior to an intervention that involved the presence versus absence of a positive reinforcement contingency applied to food consumption. Participants displayed significantly more problem behavior during the nonpreferred-foods condition. Participants consumed nonpreferred target food items only when prior access to preferred foods was limited and a positive reinforcement contingency was implemented. Functional analysis suggested that problem behavior was maintained by negative reinforcement. Intervention data suggested that establishing operations increased the efficacy of the contingency-based intervention. The implications of applying this intervention in the community were discussed as were the relative merits of stimulus fading versus escape extinction intervention strategies.
