暴饮暴食在青少年和年轻人中越来越普遍，可能对身心健康产生持久的有害影响。机制的见解表明，异常的奖励学习和偏见的认知加工可能参与暴食的病因。因此，我们研究了最近开发的方法，以催化通过pupelet更新适应不良记忆的短暂干预，也可以提高认知偏差修正训练对暴饮暴食行为的影响。一个非寻求治疗的样本90个暴饮暴食的年轻人被均匀地随机接受选择性食物反应抑制训练，或假训练后，暴饮暴食的记忆再激活。第三组接受的训练没有过度记忆激活。实验室措施的反应性和偏见的反应，食物线索进行了评估干预前和干预后9个月的暴饮暴食行为和饮食失调的评估。该方案在https://osf.io/82c4r/上预先注册。我们发现，在实验室评估的认知偏见的措施，以自我选择的图像典型的暴饮暴食的发病前偏见处理的证据有限。因此，几乎没有证据表明CBM减少了这些偏见，并且这并没有通过先前的“重新激活”暴食奖励记忆来增强。在长期暴饮暴食行为、热量消耗或饮食紊乱方面没有观察到组间差异。这些发现与最近的研究表明，选择性抑制训练对暴饮暴食的影响有限，并且不允许关于检索依赖性记忆“更新”机制作为反应抑制训练的治疗催化剂的效用的结论。
Binge eating is increasingly prevalent among adolescents and young adults and can have a lasting harmful impact on mental and physical health. Mechanistic insights suggest that aberrant reward-learning and biased cognitive processing may be involved in the aetiology of binge eating. We therefore investigated whether recently developed approaches to catalyse brief interventions by putatively updating maladaptive memory could also boost the effects of cognitive bias modification training on binge eating behaviour. A non-treatment-seeking sample of 90 binge eating young adults were evenly randomised to undergo either selective food response inhibition training, or sham training following binge memory reactivation. A third group received training without binge memory reactivation. Laboratory measures of reactivity and biased responses to food cues were assessed pre-post intervention and bingeing behaviour and disordered eating assessed up to 9 months post-intervention. The protocol was pre-registered at https://osf.io/82c4r/. We found limited evidence of premorbid biased processing in lab-assessed measures of cognitive biases to self-selected images of typical binge foods. Accordingly, there was little evidence of CBM reducing these biases and this was not boosted by prior ‘reactivation’ of binge food reward memories. No group differences were observed on long-term bingeing behaviour, caloric consumption or disordered eating symptomatology. These findings align with recent studies showing limited impact of selective inhibition training on binge eating and do not permit conclusions regarding the utility of retrieval-dependent memory ‘update’ mechanisms as a treatment catalyst for response inhibition training.
