Despite being widely debated throughout the scientific community, the concept of food addiction remains a popular explanation for overeating and obesity amongst the lay public. Overeating is often accompanied by feelings of guilt and dietary concern, and this may lead people to attribute their eating to an addiction in order to minimise personal responsibility. Research also indicates that food addiction attributions and dietary concern may lead people to limit their exposure to tempting foods. To test these ideas, we examined the effect of perceived overeating on food addiction attributions and snack choice. Subjective ratings of guilt and dietary concern were indirectly manipulated by leading female participants (N=90) to believe they had eaten more than (overeating condition), less than (undereating condition), or roughly the same (control condition) amount of palatable foods in relation to their own estimated consumption and to previous participants. Participants then rated the relative importance of a list of explanations for their eating (including "the foods were really addictive") and selected a snack to take home with them. Ratings of guilt and dietary concern were highest in the overeating condition, and lowest in the undereating condition, indicating that the manipulation had been successful. However, findings revealed no effect of condition on food addiction attributions. As predicted, participants in the overeating condition selected less tempting snacks than in the undereating condition. However, this effect was not mediated by guilt/dietary concern. There was also no association between food-addiction attributions and snack choice. These findings suggest that perceived overeating affects snack choice but not food addiction attributions. Future research should investigate whether food addiction attributions may be driven by feelings of guilt and dietary concern following longer-term disinhibited eating patterns.
尽管在科学界广泛讨论,食物成瘾的概念仍然是一个流行的解释,解释暴饮暴食和肥胖在一般公众。暴饮暴食往往伴随着内疚和饮食关注的感觉,这可能导致人们将他们的饮食归因于成瘾,以减少个人责任。研究还表明,食物成瘾归因和饮食关注可能会导致人们限制他们接触诱人的食物。为了检验这些想法,我们研究了感知的暴饮暴食对食物成瘾归因和零食选择的影响。通过让女性参与者(N=90)相信他们吃了比(暴饮暴食条件)、少于(少吃条件)或大致相同(对照条件)的美味食物,相对于他们自己的估计消费和以前的参与者,间接操纵了内疚和饮食关注的主观评价。然后,参与者对一系列解释他们饮食的原因进行了评分(包括“食物真的会上瘾”),并选择了一种零食带回家。在暴饮暴食条件下,内疚和饮食关注的评分最高,在少吃条件下最低,表明操纵是成功的。然而,研究结果并没有发现条件对食物成瘾归因的影响。正如预测的那样,在暴饮暴食条件下的参与者选择了比少吃条件下不那么诱人的零食。然而,这种影响不是由内疚/饮食关注介导的。食物成瘾归因与零食选择之间也没有关联。这些发现表明,感知的暴饮暴食会影响零食的选择,但不会影响食物成瘾的归因。未来的研究应该调查在长期的饮食失调模式下,内疚和饮食关注感是否会导致食物成瘾归因。
