儿童的压力应对行为及其决定因素尚未得到广泛研究。一些孩子在压力和饮食限制缓解了年轻人的饮食压力后吃得更多，但吃已经被孤立地从其他应对行为中进行了研究。如果有其他行为选择，儿童在压力下可能不会选择进食。其目的是确定调节压力应对选择持续时间的个体差异因素，并确定当其他压力应对行为可用时，压力诱导的进食在年轻人中是否持续存在。30名儿童(8-12岁)一天完成一项演讲压力源，另一天阅读杂志。他们完成了一段自由选择的时期，在这两天都可以获得食物、电视和体育活动。饮食限制缓和了从控制组到应激组的进食时间和能量消耗的变化。高度克制的儿童在压力日增加了他们的能量摄入量。看电视的时间变化被平时看电视的时间所缓和，因为在压力过大后，平时看电视的孩子会增加看电视的时间。因此，当其他常见的压力应对行为可以自由获得时，饮食受限的儿童在压力下吃得更多。这些结果扩展了应激诱导进食的实验室研究的外部有效性。爱思唯尔有限公司出版。
Children's stress-coping behaviors and their determinants have not been widely studied. Some children eat more after stress and dietary restraint moderates stress eating in youth, but eating has been studied in isolation of other coping behaviors. Children may not choose to eat when stressed if other behavioral alternatives are available. The purpose was to determine individual difference factors that moderate the duration of stress coping choices and to determine if stress-induced eating in youth persists when other stress coping behaviors are available. Thirty children (8-12 years) completed a speech stressor on one day and read magazines on another day. They completed a free-choice period with access to food, TV, and physical activity on both days. Dietary restraint moderated changes in time spent eating and energy consumed from the control to stress day. Children high in restraint increased their energy intake on the stress day. Changes in the time spent watching TV were moderated by usual TV time, as children higher in usual TV increased their TV time after stress. Thus, dietary restrained children eat more when stressed when other common stress coping behaviors are freely available. These results extend the external validity of laboratory studies of stress-induced eating. Published by Elsevier Ltd.
