The aim of the present proof-of-concept study was to test a novel cognitive bias modification (CBM) programme in an analogue sample of people with subclinical bulimic eating disorder (ED) psychopathology. Thirty participants with high levels of trait food craving were trained to make avoidance movements in response to visual food stimuli in an implicit learning paradigm. The intervention comprised ten 15-minute sessions over a 5-week course. At baseline, participants showed approach and attentional biases towards high-caloric palatable food that were both significantly reduced and turned into avoidance biases after the training. Participants also reported pronounced reductions in both trait and cue-elicited food craving and in ED symptoms as well. The overall evaluation of the training by the participants was positive. The specific CBM programme tested in this pilot trial promises to be an effective and feasible way to alter automatic action tendencies towards food in people suffering from bulimic ED psychopathology.
本概念验证研究的目的是在亚临床贪食症（ED）心理病理学的模拟样本中测试一种新的认知偏差修正（CBM）方案。30 名具有高特质食物渴望水平的参与者在一个内隐学习范式中接受了训练，以对视觉食物刺激做出回避动作。干预措施包括在 5 周的课程中进行十次 15 分钟的课程。在基线时，参与者表现出对高热量美味食物的趋近和注意力偏向，这些偏向在训练后均显著降低，并转变为回避偏向。参与者还报告说，特质和线索诱发的食物渴望以及 ED 症状都明显减少。参与者对培训的总体评价是积极的。在这项初步试验中测试的特定 CBM 方案有望成为改变患有贪食 ED 心理病理学的人对食物的自动行为倾向的有效且可行的方法。
