Studies in Western world patients suggest the possible existence of a subgroup of patients with bulimia nervosa (BN) who display multiple problems with impulsivity, such as suicidal attempts. We assessed impulsive behaviors among BN patients in Japan to discuss them crossculturally.
Impulsive behaviors in 64 BN patients were assessed and multi-impulsivity (MI) was defined according to the definition proposed by Fichter, Quadflieg, and Rief (Psychological Medicine, 24, 591-604,1994).
Nineteen patients (30%) met the definition of MI. BN patients with MI had more severe clinical features, such as concurrent depressive and anxious symptoms, global functioning, and higher prevalence of borderline personality disorder than BN patients without MI.
These results showed the similarities between BN patients with MI in Japan and those patients in the Western world in clinical and psychopathological characteristics and a life-time incidence of each impulsive behavior. These findings may suggest culturally free bases for linkage between BN and MI.
针对西方患者的研究表明，神经性贪食症（BN）患者中可能存在一个亚组，这类患者存在多种冲动行为问题，比如自杀企图。我们评估了日本BN患者的冲动行为，以便进行跨文化探讨。
对64名BN患者的冲动行为进行评估，并根据菲希特、夸德弗利格和里夫（《心理医学》，第24卷，第591 - 604页，1994年）提出的定义来界定多重冲动性（MI）。
19名患者（30%）符合MI的定义。与无MI的BN患者相比，有MI的BN患者具有更严重的临床特征，如并发抑郁和焦虑症状、整体功能，以及边缘性人格障碍的患病率更高。
这些结果显示，日本有MI的BN患者与西方世界的此类患者在临床和精神病理学特征以及每种冲动行为的终生发病率方面存在相似之处。这些发现可能表明BN与MI之间的联系存在不受文化影响的基础。
