Resurgence and renewal are treatment-relapse phenomena in which previously extinguished behavior returns after the conditions for an alternative response worsen or the context changes, respectively. Recently, researchers have evaluated the prevalence of resurgence and renewal when treating destructive behavior with functional communication training. However, resurgence of inappropriate mealtime behavior has yet to be evaluated; perhaps because treatments involve qualitatively different resurgence opportunities (e.g., increased bite-presentation rate). We evaluated the prevalence of resurgence and renewal of inappropriate mealtime behavior across 22 and 25 applications of extinction-based treatments, respectively. Resurgence occurred in 41% (9/22) of applications, most often following presentation-rate increases. Renewal occurred in 52% (13/25) of applications, most often following feeder changes from therapist to caregiver. We discuss these findings in terms of their ability to inform relapse-mitigation strategies for resurgence and renewal of inappropriate mealtime behavior.

小儿喂养障碍治疗期间复发

复苏和更新是治疗复发现象，在这种现象中，先前消失的行为分别在替代反应的条件恶化或背景发生变化后恢复。最近，研究人员评估了通过功能性沟通训练治疗破坏性行为时复苏和更新的普遍性。然而，进餐时间不当行为的卷土重来还有待评估；可能是因为治疗涉及质量不同的复苏机会（例如，增加咬合率）。我们分别评估了 22 种和 25 种基于消退治疗的应用中不当进餐时间行为的复发和更新的普遍性。41% (9/22) 的应用程序出现重新出现，最常见于提交率增加之后。更新发生在 52% (13/25) 的申请中，最常见的是在喂食器从治疗师更换为护理员之后。我们讨论这些发现的能力，即它们为不当进餐时间行为的复发和更新提供复发缓解策略的能力。
