执行功能在解决问题和自我控制方面起着重要作用。定势转换是执行功能的一个方面，代表了认知灵活性。暴食症（BED）中无法控制进食可能意味着设置转换的缺陷，这可能会因负面情绪和抑郁症状而加剧。这项研究的目的是测试是否有一个因果关系之间的转移能力，情绪变化和失去控制的饮食在床上。75名被诊断为BED的参与者被随机分配到消极或中性情绪诱导组。对定势转换能力、抑郁症状、当前情绪和饮食失控进行了评估。具有抑郁症状和较差的情境转移能力会导致消极情绪诱导后产生更加消极的情绪，而在中性情绪诱导中则没有观察到这一点。事后分析显示，个人较差的集转移能力和更多的负面情绪的变化，经历了更多的感情失去控制的饮食比个人的集转移能力更好，其情绪没有改变。结果表明，抑郁症状和设置转换能力的缺陷可能会降低一个人处理负面影响的能力，并增加对BED患者饮食的控制。(C)2015爱思唯尔爱尔兰有限公司版权所有。
Executive functions play an important role in problem-solving and self-control. Set-shifting is an aspect of executive functioning and represents cognitive flexibility. The inability to control eating in Binge Eating Disorder (BED) may imply deficits in set-shifting which could be exacerbated by negative mood and depressive symptoms. The aim of the study was to test whether there is a causal relationship between set-shifting ability, changes in mood and loss of control over eating in BED. Seventy-five participants diagnosed with BED were randomly assigned to a negative or neutral mood induction. Set-shifting abilities, depressive symptoms, current Mood and loss of control over eating were assessed. Having depressive symptoms and poorer set-shifting abilities resulted in a more negative mood after a negative mood induction, whereas this was not observed in the neutral mood induction. Post-hoc analyses revealed that individuals with poorer set-shifting abilities and more changes in negative mood, experienced more feelings of loss of control over eating than individuals whose set-shifting abilities were better and whose mood did not change. The results suggest that both depressive symptoms and deficits in set-shifting abilities may decrease an individual's ability to handle negative affect and increase loss of control over eating in individuals with BED.
