This study investigates whether eating behavior in women with diagnosed bulimia nervosa is influenced by prior exposure to images of ideally thin models. Twenty-six participants diagnosed with bulimia nervosa (BN) and 30 normal controls (NC) were exposed to body-related and neutral TV commercials; then food that typically triggers binge eating was provided, and the amount of food eaten was measured. No significant difference for food intake between NC and BN could be found, but food intake for BN was predicted by the degree of thoughts related to eating behaviors during exposure to the thin ideal. No impact of general body image or eating pathology on food intake could be found. The results emphasize the importance of action-relevance of dysfunctional cognitions for the maintenance of eating-disordered behaviors in women with bulimia nervosa, when exposed to eating-disorder-specific triggers.
本研究旨在探讨女性神经性贪食症患者的进食行为是否受到理想化瘦模特图片曝光的影响。研究招募了 26 名被诊断为神经性贪食症（BN）的患者和 30 名正常对照组（NC）参与者，让他们观看与身体相关的和中性的电视广告；然后提供了通常会引发暴食的食物，并测量了他们吃的食物量。研究未发现 NC 和 BN 两组之间的食物摄入量有显著差异，但 BN 组的食物摄入量与对瘦理想的曝光期间与进食行为相关的思维程度有关。研究未发现一般身体形象或饮食病理学对食物摄入量有影响。结果强调了在暴露于饮食失调特异性触发因素时，对进食障碍行为的功能失调认知的行为相关性对维持神经性贪食症女性患者的进食障碍行为的重要性。
