Binge eating is predicted by emotion dysregulation and poor emotional awareness. Dysfunctional metacognition is also implied in several eating disorders, but research has not yet investigated the interactions among emotional and metacognitive processes involved in binge eating. The present study investigated the relation between metacognition and binge eating in a sample of adolescents, testing the interaction effect between the need to control thoughts and the lack of emotional awareness on binge eating.
Participants were 804 adolescents (age range 15-20; 49.7% female), who completed self-report instruments assessing binge eating, emotion regulation, and metacognition.
Binge eating was predicted by gender, BMI, emotion dysregulation, lack of emotional awareness, and dysfunctional metacognition dimensions (cognitive confidence and need to control thoughts). An important moderating effect was found, whereby the relationship between binge eating and lack of emotional awareness was only significant for individuals with a high need to control thoughts.
Results described emotional and metacognitive functioning in binge eating adolescents, suggesting that the need to control thoughts is a risk factor, whereas good metacognitive competencies are protective from binge eating, even in presence of poor emotional awareness.

情绪调节障碍和情绪意识差可预测暴饮暴食。功能失调的元认知也与几种饮食失调有关，但研究尚未探讨暴饮暴食中涉及的情绪和元认知过程之间的相互作用。本研究调查了青少年样本中元认知与暴饮暴食之间的关系，测试了控制思维的需求与缺乏情绪意识对暴饮暴食的交互作用。
参与者为804名青少年（年龄范围15 - 20岁；49.7%为女性），他们完成了评估暴饮暴食、情绪调节和元认知的自我报告工具。
暴饮暴食可由性别、体重指数、情绪调节障碍、缺乏情绪意识和功能失调的元认知维度（认知信心和控制思维的需求）预测。发现了一个重要的调节效应，即暴饮暴食与缺乏情绪意识之间的关系仅在控制思维需求高的个体中显著。
结果描述了暴饮暴食青少年的情绪和元认知功能，表明控制思维的需求是一个风险因素，而良好的元认知能力可预防暴饮暴食，即使在情绪意识较差的情况下也是如此。
