The study aimed to analyze the role of depression and impulsivity in the psychopathology of bulimia nervosa (BN).
Seventy female patients with DSM-IV BN, purging subtype, were assessed for eating-related symptoms, body dissatisfaction, affective symptoms, impulsivity, and personality traits. Factor analysis and structural equation modeling methods were used for statistical analysis.
BN appeared as a condition which incorporated 5 general dimensions: a) binge eating and compensatory behaviours; b) restrictive eating; c) body dissatisfaction; d) dissocial personality traits; and e) a cluster of features which was called «emotional instability» The 5 obtained dimensions can be grouped into 2 basic factors: body dissatisfaction/eating behaviour and personality traits/psychopathology. The first one contains the clinical items used for the definition of BN as a clinical condition in the DSM-V and the International Classification of Diseases 10, and reflects the morphology and the severity of the eating-related symptoms. The second dimension includes a cluster of symptoms (depressive symptoms, impulsivity, and borderline, self-defeating and dissocial personality traits) which could be regarded as the «psychopathological core» of BN and may be able to condition the course and the prognosis of BN.
本研究旨在分析抑郁和冲动在神经性贪食症（BN）精神病理学中的作用。
对 70 名 DSM-IV BN 、清除型女性患者进行与饮食相关的症状、身体不满、情感症状、冲动和人格特质评估。采用因子分析和结构方程模型方法进行统计分析。
BN 表现为一种包含 5 个一般维度的疾病：a）暴食和补偿行为；b）限制进食；c）身体不满；d）反社会人格特质；和 e）称为“情绪不稳定”的特征群。获得的 5 个维度可以分为 2 个基本因素：身体不满/饮食行为和人格特质/精神病理学。第一个因素包含 DSM-V 和国际疾病分类第 10 版中用于 BN 临床定义的临床项目，反映了饮食相关症状的形态和严重程度。第二个维度包括一系列症状（抑郁症状、冲动和边缘、自我挫败和反社会人格特质），这些症状可被视为 BN 的“精神病理学核心”，可能影响 BN 的病程和预后。
