We evaluated the separate components in treatment packages for food refusal of 4 young children. First, treatment packages were implemented until food acceptance improved. Next, a component analysis was conducted within a multielement or reversal design to identify the active components that facilitated food acceptance. The results indicated that escape extinction was always identified as an active variable when assessed; however, other variables, including positive reinforcement and noncontingent play, were also identified as active variables for 2 of the children. The results suggest that the component analysis was useful for identifying variables that affected food acceptance.
我们评估了针对4名幼儿食物拒绝问题的治疗方案中的各个组成部分。首先,实施治疗方案直至食物接受情况有所改善。接下来,在多元素或反转设计中进行成分分析,以确定促进食物接受的有效成分。结果表明,在评估时,逃避消退总是被确定为一个有效变量;然而,其他变量,包括正强化和非偶然游戏,也被确定为其中2名儿童的有效变量。结果表明,成分分析有助于识别影响食物接受的变量。
