An understanding of the functional variables associated with inappropriate mealtime behavior (IMB) is critical to developing an effective and efficient treatment for food refusal. To this aim, functional analysis methodology has been modified for the meal context, and previous research has shown that multiple sources of reinforcement maintain IMB. Functional analysis literature, related to severe problem behavior, suggests that access to preferred stimuli may abolish or compete with social reinforcers in some cases. The role of noncontingent access to preferred stimuli during the assessment of IMB has not been evaluated. The purpose of the current study was to examine the effects noncontingent access to preferred toys/activities on IMB in the presence and absence of social consequences. The specific aims were to evaluate: (1) levels of IMB when the spoon is held stationary at the child's lips when preferred tangible stimuli are present noncontingently vs. absent; (2) levels of IMB when social consequences were provided contingent upon IMB when preferred tangible stimuli are present noncontingently vs. absent. For many participants, levels of IMB were reduced with the inclusion of preferred toys/activities; while for one, levels of IMB increased. Possible implications of these findings on functional analyses of IMB will be discussed.
了解与不适当进餐行为(IMB)相关的功能变量对于开发有效且高效的拒食治疗方法至关重要。为此,功能分析方法已针对进餐情境进行了修改,先前的研究表明多种强化来源维持着IMB。与严重问题行为相关的功能分析文献表明,在某些情况下,接触偏好刺激可能会消除或与社会强化物竞争。在IMB评估过程中,非偶然性接触偏好刺激的作用尚未得到评估。本研究的目的是检验在有和没有社会后果的情况下,非偶然性接触偏好玩具/活动对IMB的影响。具体目标是评估:(1)当偏好的有形刺激非偶然性存在与不存在时,勺子固定在儿童嘴唇处时的IMB水平;(2)当偏好的有形刺激非偶然性存在与不存在时,根据IMB提供社会后果时的IMB水平。对于许多参与者来说,纳入偏好玩具/活动后IMB水平降低;而对于一名参与者,IMB水平增加。将讨论这些发现对IMB功能分析的可能影响。
