Studies have linked increased impulsivity and compulsivity with bulimia nervosa (BN). Less is known about this relationship in binge eating disorder (BED).
Seventy-nine overweight participants (28 male, 65 females) were classified as BED (n = 22), BE (Subthreshold BED, not meeting full criteria for BED) (n = 21), and non-BED (n = 36). Following an 8-hr fast, participants completed psychological scales to assess impulsivity, compulsivity, and depression. They then consumed a liquid test meal until extremely full.
Test meal intake (TMI) was significantly greater for both BED and BE than non-BED participants. Impulsivity and depression scores were significantly higher in BED and BE than in non-BED participants. Men had significantly higher compulsivity scores than women. Impulsivity correlated significantly with TMI, accounting for 16% of the variance.
There was greater impulsivity in BED and BE, compared with non-BED. Moreover, impulsivity was the best predictor of TMI, and may play a larger role in BE than previously realized.
研究已将冲动性和强迫性增加与神经性贪食症（BN）联系起来。在暴饮暴食症（BED）中，关于这种关系的了解较少。
79名超重参与者（28名男性，65名女性）被分为暴饮暴食症组（n = 22）、亚阈值暴饮暴食症组（未达到暴饮暴食症的全部标准，BE）（n = 21）和非暴饮暴食症组（n = 36）。在禁食8小时后，参与者完成心理量表以评估冲动性、强迫性和抑郁程度。然后他们食用流食测试餐直至极度饱腹。
暴饮暴食症组和亚阈值暴饮暴食症组的测试餐摄入量（TMI）均显著高于非暴饮暴食症组参与者。暴饮暴食症组和亚阈值暴饮暴食症组的冲动性和抑郁得分显著高于非暴饮暴食症组参与者。男性的强迫性得分显著高于女性。冲动性与测试餐摄入量显著相关，占方差的16%。
与非暴饮暴食症组相比，暴饮暴食症组和亚阈值暴饮暴食症组存在更大的冲动性。此外，冲动性是测试餐摄入量的最佳预测指标，并且在亚阈值暴饮暴食症中可能比之前认识到的发挥更大作用。
