Although impulsive behavioral patterns are often described by patients with bulimia nervosa, there has been little formal evaluation of the relationship between impulsivity and eating-related symptomatology in this disorder. In this controlled outpatient study, ratings on the Barratt Impulsivity Scale were significantly elevated in 20 women with bulimia nervosa in comparison to 20 healthy female volunteers. Frequency of binge eating episodes was not significantly correlated with impulsivity ratings. Although these results indicate increased prevalence of impulsive behavioral style in patients with bulimia nervosa, impulsivity per se does not appear to be a predictor of symptom severity as reflected in frequency of bulimic episodes.
尽管神经性贪食症患者常描述有冲动行为模式，但对于该疾病中冲动性与饮食相关症状之间的关系，几乎没有进行过正式评估。在这项对照门诊研究中，与20名健康女性志愿者相比，20名神经性贪食症女性患者在巴拉特冲动量表上的评分显著升高。暴饮暴食发作的频率与冲动性评分无显著相关性。尽管这些结果表明神经性贪食症患者中冲动行为风格的患病率增加，但冲动性本身似乎并不是如贪食发作频率所反映的症状严重程度的预测指标。
