Overweight women with and without binge eating disorder (BED) are characterized by a marked body dissatisfaction, which may in part be due to the negative comments about their weight. Weight-related teasing and discrimination is reported both by healthy overweight women and women with BED, whereas body dissatisfaction is markedly increased among women with BED. Therefore, a memory bias for negatively valenced body-related cues is suspected to occur as a mediating factor in women with BED. In an experimental study, 18 women with BED were compared to 18 overweight healthy female controls (HC) on a free recall task containing four word categories: positively valenced with and without body-related content and negatively valenced with and without body-related content. While both groups showed a bias towards negatively valenced shape-/weight-related words, women with BED retrieved positively valenced shape-/weight-related words significantly less often compared to overweight HC. Findings suggest that it may be the reduced ability to attend to positively valenced shape-/weight-related information, rather than the activation of negative body schemata that differentiates overweight women with BED from overweight women without BED. Results are discussed in the context of cognitive biases in the maintenance of body dissatisfaction.
患有或未患有暴食障碍（BED）的超重女性都表现出明显的身体不满，这部分可能是由于对她们体重的负面评价。超重的健康女性和患有 BED 的女性都报告了与体重相关的嘲笑和歧视，而 BED 女性的身体不满明显增加。因此，对具有负面价值的身体相关线索的记忆偏差被怀疑是 BED 女性的一个中介因素。在一项实验研究中，将 18 名患有 BED 的女性与 18 名超重健康女性对照组（HC）在一个自由回忆任务中进行比较，该任务包含四个单词类别：有和没有身体相关内容的积极情绪和有和没有身体相关内容的消极情绪。虽然两组都表现出对负面价值的体型/体重相关词汇的偏见，但与超重 HC 相比，患有 BED 的女性对积极价值的体型/体重相关词汇的回忆明显减少。研究结果表明，区分患有 BED 的超重女性和未患有 BED 的超重女性的可能是对积极价值的体型/体重相关信息的关注能力下降，而不是负面身体图式的激活。研究结果在维持身体不满的认知偏差的背景下进行了讨论。
