The current study aimed to examine the effects of approach bias for unhealthy food and trait eating style on consumption of unhealthy food in overweight and normal weight individuals.
Participants were 245 undergraduate women aged 17 - 26 years. They completed an Approach-Avoidance Task, the Dutch Eating Behaviour Questionnaire (to assess restrained, emotional, and external eating), and a taste test to measure consumption of unhealthy food.
An external eating style predicted increased consumption of unhealthy food. Among overweight participants, external and emotional eating style individually moderated the relationship between approach bias for unhealthy food and subsequent consumption. Specifically, approach bias was positively related to consumption in high external and emotional eaters, but negatively related to consumption in low emotional eaters. These interactions were not observed among normal weight participants.
Practically, the results suggest that overweight individuals who are external or emotional eaters may benefit from interventions that aim to modify approach bias towards unhealthy food cues to reduce problematic eating behaviour.
本研究旨在探讨超重和正常体重个体对不健康食品的趋近偏向及特质饮食方式对不健康食品消费的影响。
参与者为245名年龄在17至26岁之间的本科女生。她们完成了一项趋避任务、荷兰饮食行为问卷（用于评估克制性、情绪化和外部性饮食）以及一项味觉测试以测量不健康食品的消费量。
外部性饮食方式预示着不健康食品消费量的增加。在超重参与者中，外部性和情绪化饮食方式分别调节了对不健康食品的趋近偏向与随后消费量之间的关系。具体而言，在高外部性和高情绪化饮食者中，趋近偏向与消费量呈正相关，但在低情绪化饮食者中，趋近偏向与消费量呈负相关。在正常体重参与者中未观察到这些交互作用。
实际上，研究结果表明，作为外部性或情绪化饮食者的超重个体可能会从旨在改变对不健康食品线索的趋近偏向以减少问题饮食行为的干预措施中受益。
