Background: While positive reinforcement is perhaps the most common component in interventions for feeding problems, the literature suggests it is not sufficient to address more severe problems.

Method: An ABACDB reversal design was used to evaluate the effectiveness of praise, in-session reinforcement, and a visual cue + post-session reinforcement to increase solid food consumption in a nine-year-old boy with an intellectual disability who was completely dependent upon gastrostomy tube feeds.

Results and Discussion: A combination of praise, in-session reinforcement, and the visual cue + post-session reinforcement was more effective at increasing bites consumed than praise combined with either one of the other two components. The results suggested a multiplicative effect. Multiple reinforcement components may be considered in the treatment of persons with feeding problems as either an alternative to escape extinction or a method of minimizing escape extinction.

背景：虽然积极强化可能是干预喂养问题中最常见的组成部分，但文献表明，这不足以解决更严重的问题。

方法：采用ABACDB逆向设计评估表扬，闭会期间强化和视觉提示+闭会后强化的有效性，以增加一个完全依赖的9岁智障男孩的固体食物消耗胃造口管喂食时。

结果与讨论：赞美，会话中强化和视觉提示+会话后强化相结合比结合其他两个要素之一的赞美更有效地增加了咬伤。结果提示了相乘作用。在治疗有进食问题的人时，可以考虑使用多种加固部件，以作为逃生灭绝的替代方法或最小化逃生灭绝的方法。
