The feeding behaviors of two children who maintained failure to thrive diagnoses and displayed food refusal are assessed in their homes. Descriptive assessments are used to identify schedules of consequence provided by each child's care providers for bite acceptance and food refusal behaviors. Assessments reveal rich schedules of praise and access to social interaction and preferred activities for bite acceptance and escape for food refusal. These schedule arrangements result in hypotheses that modifications to the schedule of praise and access to social interaction and preferred activities for bite acceptance would result in little to no effect and that modifications to the schedule of escape for food refusal would be necessary for treatment success. Successful interventions are subsequently implemented by manipulating the existing schedules of escape for food refusal by each child's care providers. Implications for the use of descriptive assessments for feeding problems are discussed.
对两名被诊断为发育不良且存在食物拒绝行为的儿童在其家中的进食行为进行了评估。采用描述性评估来确定每个孩子的照料者针对咬食接受和食物拒绝行为所提供的后果安排。评估发现,对于咬食接受行为,有丰富的表扬安排以及获得社交互动和偏好活动的机会;对于食物拒绝行为,则有逃避的安排。这些安排导致了这样的假设:改变咬食接受行为的表扬安排以及获得社交互动和偏好活动的机会,几乎不会产生效果或根本没有效果,而改变食物拒绝行为的逃避安排对于治疗成功是必要的。随后,通过操纵每个孩子的照料者现有的食物拒绝逃避安排来实施成功的干预措施。文中还讨论了描述性评估在喂养问题中的应用意义。
