Changes of eating in response to a real life stressor were examined in field study using a control group design with pre- and posttest. Students (n=22) awaiting an exam and control subjects (n=20) were assessed 3-4 weeks and 3-4 days before the exam. They were given a pager, which beeped ten times a day at random intervals. Upon each signal, participants rated their emotional state and motivations to eat. If they had eaten since the last signal they reported the perceived function of their actual eating behavior. Compared to control subjects, students awaiting an exam reported higher emotional stress and an increased tendency to eat in order to distract themselves from stress. Results indicate that emotion regulation through eating is experienced in a student population during stress under real life conditions with distraction as a possible mediating mechanism.
在一项实地研究中，采用前后测对照组设计，研究了应对现实生活压力源时饮食的变化。在考试前3 - 4周和3 - 4天，对等待考试的学生（n = 22）和对照组受试者（n = 20）进行了评估。给他们配备了传呼机，传呼机每天以随机间隔发出十次哔哔声。每次信号响起时，参与者对自己的情绪状态和进食动机进行评分。如果他们自上次信号响起后进食了，就报告其实际进食行为的感知功能。与对照组受试者相比，等待考试的学生报告的情绪压力更高，并且为了从压力中分心而增加了进食倾向。结果表明，在现实生活压力下，学生群体中存在通过进食进行情绪调节的现象，分心可能是一种中介机制。
