Treatment of one behavior in the chain of consumption might be associated with the emergence of other problematic behaviors. For example, some children with feeding disorders expel liquid. Moreover, the form in which children expel liquid might vary and influence whether a treatment to reduce liquid expulsion will result in clinically meaningful outcomes. In the current investigation, we first identified topographies of liquid expulsion (e.g., forceful, run out) for each child. We then compared and evaluated the effects of 2 procedures, a modified chin prompt and re-presentation, on the liquid expulsion of 3 children with feeding disorders. For 2 participants, expulsion decreased to clinically meaningful levels with a modified chin prompt or re-presentation. However, for 1 participant, expulsion decreased to clinically meaningful levels only when we combined the modified chin prompt and re-presentation as part of a treatment package. We discuss possible mechanisms underlying the effects of a modified chin prompt and re-presentation, in addition to areas for future research.
治疗消费链中的一种行为可能会与其他问题行为的出现有关。例如，一些患有进食障碍的儿童会吐出液体。此外，儿童吐出液体的方式可能会有所不同，并影响减少液体吐出的治疗是否会产生临床有意义的结果。在当前的研究中，我们首先确定了每个儿童液体吐出的行为模式（例如，用力吐、流出来）。然后，我们比较和评估了两种程序的效果，即改良的下巴提示和重新呈现，对 3 名进食障碍儿童液体吐出的影响。对于 2 名参与者，改良的下巴提示或重新呈现使液体吐出减少到具有临床意义的水平。然而，对于 1 名参与者，只有当我们将改良的下巴提示和重新呈现结合起来作为治疗方案的一部分时，液体吐出才会减少到具有临床意义的水平。我们讨论了改良下巴提示和重新呈现效果的可能机制，以及未来研究的领域。
