This case study describes inter-disciplinary treatment of chronic food refusal and tube dependency in a 2-year-old female with a pediatric feeding disorder. Evidence-based behavioral components-including escape extinction (EE), differential reinforcement of alterative mealtime behavior (DRA), and stimulus fading-were introduced sequentially as the focus of treatment shifted to address refusal topographies along the chain of behaviors associated with consumption. The assessment process, treatment planning and sequencing, and generalization of treatment gains to caregivers are presented in detail. In doing so, the study illustrates the core features involved in applying a flexible, evidenced-based approach to treat severe feeding difficulties. © Taylor & Francis Group, LLC.

The current study examined the effect of blending established foods and non-preferred foods to treat expulsions in a three-year-old girl with food refusal and gastrostomy-tube dependence. Treatment involving differential reinforcement of acceptance, non-removal of the spoon, and re-presentation increased consumption of 12 out of the 16 pureed foods; however, high levels of expulsion of four foods continued to disrupt meals. Results showed reduced rates of expulsion and increased mouth clean during blending, evaluated empirically using an ABAB design. © 2015 John Wiley & Sons, Ltd.
