研究目的冲动可能导致肥胖和饮食失调的发生和维持。暴饮暴食症（BED）患者表现出以规律暴饮暴食发作为特征的冲动性饮食模式。新的行为干预增加抑制控制可以改善BED的饮食行为。我们试行了一种新的食物特异性抑制训练的个人BED.Methods N = 22 BED患者根据SCID-I随机分配到三个会议的培训或控制条件。在这两种情况下，高热量食物的图片被呈现在计算机屏幕上的周边视觉，同时评估凝视行为。训练组必须抑制将目光转向这些图片的冲动（即，进行反突击）。控制组被允许自由探索图片。我们评估了自我报告的食物渴望，食物成瘾，并希望/喜欢的食物图片前和后intervention.Results二十参与者完成了研究。培训证明是可行和可接受的。训练组患者对高热量食物刺激的抑制控制能力显著提高。在研究结束后的最后四周，两组都报告了明显较低的暴饮暴食事件。没有变化，发现在食物的渴望，食物成瘾，喜欢，并希望rates.Conclusions的食物特异性抑制训练可能是一个有用的元素，在治疗床和其他饮食失调，但是，更大的疗效研究患者样本需要调查的疗效，这和类似的训练方法。
Purpose Impulsivity might contribute to the development and maintenance of obesity and eating disorders. Patients suffering from binge eating disorder (BED) show an impulsive eating pattern characterized by regular binge eating episodes. Novel behavioral interventions increasing inhibitory control could improve eating behavior in BED. We piloted a novel food-specific inhibition training in individuals with BED.Methods N = 22 BED patients according to SCID-I were randomly assigned to three sessions of a training or control condition. In both conditions, pictures of high-caloric food items were presented in peripheral vision on a computer screen while assessing gaze behavior. The training group had to suppress the urge to turn their gaze towards these pictures (i.e., to perform antisaccades). The control group was allowed to freely explore the pictures. We assessed self-reported food craving, food addiction, and wanting/liking of food pictures pre- and post-intervention.Results Twenty participants completed the study. The training proved to be feasible and acceptable. Patients of the training group significantly improved inhibitory control towards high-caloric food stimuli. Both groups reported a significantly lower number of binge eating episodes in the last four weeks after termination of the study. No changes were found in food craving, food addiction, liking, and wanting ratings.Conclusions A food-specific inhibition training could be a useful element in the treatment of BED and other eating disorders; however, larger efficacy studies in patient samples are needed to investigate the efficacy of this and similar training approaches.
