双过程模型认为，冲动行为在适应不良饮食模式的发展和维持中起着关键作用。饮食领域以外的研究表明，接近回避训练，一种旨在改变对关键刺激的自动行为倾向的范式，是削弱不健康冲动的有效工具。本研究旨在验证在进食领域进行回避训练的有效性。我们在正常体重的女学生人群（总N = 258）中进行了三次单次会议研究，采用不同的方法，其中一组总是接受训练，以避免不健康食品的图片，并接近健康食品或中性物体的图片。我们没有发现确凿的证据表明，接近回避训练可以改变参与者的内隐和外显的食物偏好和饮食行为。我们讨论的潜力和避免接近训练在饮食领域的局限性，并为未来的研究途径提供建议。(C)2014爱思唯尔有限公司版权所有。
Dual-process models propose that impulsive behavior plays a key role in the development and maintenance of maladaptive eating patterns. Research outside the eating domain suggests that approach avoidance training, a paradigm which aims to modify automatic behavioral dispositions toward critical stimuli, is an effective tool to weaken unhealthy impulses. The present research tested the effectiveness of approach avoidance training in the eating domain. We conducted three single session studies with varying methodologies in a normal-weight female student population (total N = 258), in which one group was always trained to avoid pictures of unhealthy food and to approach pictures of healthy food or neutral objects. We found no conclusive evidence that approach avoidance training can change participants' implicit and explicit food preferences and eating behavior. We discuss the potential and the limitations of approach avoidance training in the eating domain and provide suggestions for future research avenues. (C) 2014 Elsevier Ltd. All rights reserved.
