An evaluation of fading procedures in the treatment of pediatric feeding disorders: a component analysis

In the treatment of food selectivity, packages consisting of multiple components are typically utilized, often including an escape extinction procedure. Previous research has demonstrated that these treatment packages are successful in increasing consumption of target foods, as well as decreasing inappropriate mealtime behaviors. However, due to initial negative side effects of escape extinction (i.e., an immediate increase in inappropriate mealtime behaviors), caregivers may be likely implement and/or to adhere to the procedures. The current study investigated the role of less intrusive interventions prior to the introduction of escape extinction. Specifically, the current study evaluated various fading procedures (e.g., texture and liquid fading) using a component analysis by first introducing fading, then differential reinforcement, and finally escape extinction, when needed. Results indicated that escape extinction may not be necessary in all cases and contribute evidence to the recommendation to include and/or start with antecedent based interventions when treating food refusal.
