背景。人际过程、焦虑和情绪调节困难构成了神经性厌食症（AN）和神经性贪食症（BN）等饮食失调（ED）概念模型的关键部分，但支持这一点的实验结果有限。对 190 名女性 [50 名 AN、50 名 BN 和 90 名健康对照 (HC)] 进行了“从眼睛中读懂内心”任务、情绪调节困难量表 (DERS) 和计算机化图画（愤怒和中性面孔）Stroop 任务。结果。与 HC 相比，患有 ED 的人对一般面孔表现出注意力偏差（中等效应），但特别是对愤怒的面孔而不是中性面孔（大效应）。 ED 组还报告了比 HC 组显着更高的情绪调节困难（影响大）。 ED 组和 HC 组之间的情绪识别任务存在微小差异（小-中效应），特别是在限制性 AN (RAN) 组中。在回归模型中，抑郁症和对面孔的注意力偏差显着预测了情绪调节困难。结论。这些数据为 ED 的概念化提供了支持，强调情绪功能在 ED 的发展和维持中的作用。进一步的研究将集中于探索这些发现是否是 ED 的状态特征或特质特征。
Background. Interpersonal processes, anxiety and emotion regulation difficulties form a key part of conceptual models of eating disorders (EDs), such as anorexia nervosa (AN) and bulimia nervosa (BN), but the experimental findings to support this are limited.Method. The Reading the Mind in the Eyes task, the Difficulties in Emotion Regulation Scale (DERS) and a computerized pictorial (angry and neutral faces) Stroop task were administered to 190 women [50 with AN, 50 with BN and 90 healthy controls (HCs)].Results. Those with an ED showed attentional biases to faces in general (medium effect), but specifically to angry faces over neutral faces (large effect) compared to HCs. The ED group also reported significantly higher emotion regulation difficulties (large effect) than HCs. There was a small difference between the ED and HC groups for the emotion recognition task (small-medium effect), particularly in the restricting AN (RAN) group. Depression and attentional bias to faces significantly predicted emotion regulation difficulties in a regression model.Conclusions. The data provide support for conceptualizations of EDs that emphasize the role of emotional functioning in the development and maintenance of EDs. Further research will concentrate on exploring whether these findings are state or trait features of EDs.
