Renewal, the increase in problem behavior during extinction following a context change (e.g., transfer of intervention from clinic to home), may be particularly concerning during interventions for feeding disorders because multiple context changes are often necessary for intervention generality and maintenance (Podlesnik et al., 2017). In the current study, we tested for renewal and evaluated a renewal-mitigation procedure when we transferred the intervention from a therapist to a caregiver, from clinic to the home, and introduced Context A foods. We used an ABA arrangement to evaluate the generality of the renewal effect with 7 children with feeding disorders. Context A was functional reinforcement. Context B was function-based extinction during the control and mitigation conditions and our renewal-mitigation procedure in the mitigation condition. The renewal test was function-based extinction in Context A. We observed renewal of inappropriate mealtime behavior following an implementer, setting, and implementer plus setting change. Of the children for whom we observed renewal, our renewal-mitigation procedures were effective for 4 of 4 children.
