Abstract

The term renewal describes the recurrence of previously extinguished behavior that occurs when the intervention context changes. Renewal has important clinical relevance as a paradigm for studying treatment relapse because context changes are necessary for generalization and maintenance of most intervention outcomes (Podlesnik, Kelley, Jimenez-Gomez, & Bouton, 2017). The effect of context changes are particularly important during intervention for children with feeding disorders because children eat in a variety of contexts, and extinction is an empirically supported and often necessary intervention. Therefore, we used an ABA arrangement to test for renewal during intervention with 3 children diagnosed with a feeding disorder. The A phase was functional reinforcement of inappropriate mealtime behavior in a simulated home setting with the child’s caregiver as feeder; B was function-based extinction in a standard clinic setting with a therapist as feeder; and the return to the A phase was function-based extinction in a simulated home setting with caregiver as feeder. Returning to Context A resulted in renewal of inappropriate mealtime behavior across children, despite the caregivers’ continued implementation of function-based extinction with high levels of integrity.
