To test whether intolerance of uncertainty (IU) is related to eating disorder (ED) pathology.
Thirty individuals with anorexia nervosa (AN), 19 with bulimia nervosa (BN), and 28 healthy control women (CW) completed the Intolerance of Uncertainty Scale (IUS).
AN and BN groups showed higher IU compared with CW. In AN and BN, Harm Avoidance and Depression scores were positively correlated with IU. In AN but not BN, IU was related positively to Drive for Thinness and Body Dissatisfaction.
Elevated IU is associated with AN and BN. Anxious traits may be inherent in EDs and IU could be a developmental factor contributing to anxiety, mood, and ED behavior in AN and BN.
检验不确定性容忍度（IU）是否与饮食障碍（ED）病理有关。
30 名神经性厌食症（AN）患者、19 名神经性贪食症（BN）患者和 28 名健康对照组女性（CW）完成了不确定性容忍度量表（IUS）。
AN 和 BN 组的 IU 高于 CW。在 AN 和 BN 中，回避和抑郁分数与 IU 呈正相关。在 AN 中，但不在 BN 中，IU 与瘦欲和身体不满呈正相关。
IU 与 AN 和 BN 有关。焦虑特质可能是 ED 的固有特征，IU 可能是导致 AN 和 BN 中焦虑、情绪和 ED 行为的发展因素。
