The purpose of the current investigation was to apply the functional analysis described by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) to the inappropriate mealtime behaviors of 15 children who had been referred to an intensive program for the assessment and treatment of severe feeding disorders. During Study 1, we conducted descriptive assessments of children and parents during meals. The results of Study 1 showed that parents used the following consequences for inappropriate mealtime behaviors: coaxing and reprimanding, allowing the child to periodically take a break from or avoid eating, and giving the child preferred food or toys following inappropriate behavior. The effects of these consequences were tested systematically in Study 2 when we conducted analogue functional analyses with the children. During alternating meals, one of the consequences typically used by parents consistently followed inappropriate child behavior. Results indicated that these consequences actually worsened behavior for 10 of the 15 children (67%). These results suggested that the analogue functional analysis described by Iwata et al. may be useful in identifying the environmental events that play a role in feeding disorders.
本次调查的目的是将Iwata、Dorsey、Slifer、Bauman和Richman（1982/1994）所描述的功能分析应用于15名儿童不适当的用餐行为，这些儿童被转介到一个针对严重喂养障碍评估和治疗的强化项目中。在研究1中，我们在进餐期间对儿童及其父母进行了描述性评估。研究1的结果表明，父母对不适当的用餐行为采用了以下后果：哄劝和斥责、允许孩子定期休息或不吃东西，以及在孩子出现不适当行为后给予其喜欢的食物或玩具。在研究2中，当我们对这些儿童进行模拟功能分析时，系统地测试了这些后果的影响。在交替进餐期间，父母通常使用的一种后果会持续跟随孩子的不适当行为。结果表明，这些后果实际上使15名儿童中的10名（67%）的行为恶化。这些结果表明，Iwata等人所描述的模拟功能分析可能有助于识别在喂养障碍中起作用的环境事件。
