College student participants (N=1063; 77.8% response rate) completed a web-based survey assessing demographics, depression, anxiety, body image, cigarette smoking, and weight history. Among overweight participants, 42.6% of those who believed they were overweight admitted to binge eating, while only 30.1% who did not feel overweight did so (p<.05). Among non-overweight participants, 43.2% of those who believed they were overweight admitted to binge eating, while only 32.9% of those who did not feel overweight did so (p<.05). Weight Problem Perception (WPP) mediated the contribution of BMI on binge eating outcomes, and WPP contributed significantly to the prediction of binge eating, beyond the risk conferred by established correlates of binge eating (e.g., gender, mood, and cigarette smoking). Results suggest that when assessing risk for binge eating, a one-question assessment of whether or not an individual believes s/he is overweight has significant predictive power. Findings are consistent with literature on the importance of the "fat self-schema" [Stein, K.F., & Corte, C. (2007). Identity impairment and the eating disorders: Content and organization of the self-concept in women with anorexia nervosa and bulimia nervosa. European Eating Disorders Review, 15 (1), 58-69] in disordered eating and theory implicating identity in the maintenance of addictive behavior [West, R.W. (2006). Theory of Addiction.

大学生参与者(N = 1063;回复率77.8%)完成了一项基于网络的调查,评估人口统计学特征、抑郁、焦虑、身体意象、吸烟情况和体重史。在超重参与者中,认为自己超重的人中有42.6%承认有暴饮暴食行为,而不认为自己超重的人中只有30.1%有此行为(p<0.05)。在非超重参与者中,认为自己超重的人中有43.2%承认有暴饮暴食行为,而不认为自己超重的人中只有32.9%有此行为(p<0.05)。体重问题认知(WPP)介导了BMI对暴饮暴食结果的影响,并且WPP对暴饮暴食的预测有显著贡献,超出了暴饮暴食既定相关因素(如性别、情绪和吸烟)所带来的风险。结果表明,在评估暴饮暴食风险时,一个关于个人是否认为自己超重的单问题评估具有显著的预测能力。研究结果与关于“肥胖自我图式”[斯坦因,K.F.,& 科尔特,C.(2007年)。身份障碍与饮食失调:神经性厌食症和神经性贪食症女性的自我概念内容与组织。《欧洲饮食失调评论》,15(1),58 - 69]在饮食失调中的重要性的文献以及将身份认同与成瘾行为维持相关的理论[韦斯特,R.W.(2006年)。成瘾理论。马尔登,马萨诸塞州:布莱克韦尔出版公司]一致。
