The objective of the study was to analyse shared commonalities and differences between bulimia nervosa (BN) and certain impulse-related disorders, namely compulsive buying (CB) and gambling disorder (GD), with respect to general psychopathology and personality traits.
A total of 188 female patients [50 BN without comorbid CB (BN-CB), 49 BN with comorbid CB (BN+CB), 53 GD and 36 CB] and 50 comparison non-psychiatric women participated in the current study. All patients were diagnosed using the Diagnostic and Statistical Manual of Mental Disorders, Fourth revised edition, the Temperament and Character Inventory-Revised, and other clinical indices.
A positive-growing trend was observed in psychopathology and personality traits across the four clinical groups. Comorbid BN with CB was associated with highest eating psychopathology and social anxiety. On Novelty Seeking, the CB, GD and BN+CB were similar to each other, whereas BN-CB presented a distinct profile. Moreover, the BN+CB group displayed more dysfunctional personality traits and higher general psychopathology. The clinical groups demonstrated overall higher levels of psychopathology compared with the control group.
The results of this study demonstrate that disorders with impulsive traits (CB, GD, BN+CB and BN-CB) follow a linear trend in general psychopathology and specific personality traits, but differ along specific personality and psychopathological dimensions.
本研究旨在分析神经性贪食症（BN）与某些冲动相关障碍（即强迫性购物（CB）和赌博障碍（GD））之间在一般精神病理学和人格特征方面的共同和不同之处。
共有 188 名女性患者[50 名无共病 CB 的 BN（BN-CB），49 名 BN 共病 CB（BN+CB），53 名 GD 和 36 名 CB]和 50 名非精神病对照女性参加了本研究。所有患者均采用《精神障碍诊断与统计手册》第四版、《气质与性格量表修订版》及其他临床指标进行诊断。
四个临床组的精神病理学和人格特征呈正增长趋势。共病 BN 与 CB 与最高的饮食病理学和社交焦虑有关。在寻求新奇方面，CB、GD 和 BN+CB 彼此相似，而 BN-CB 则呈现出截然不同的特征。此外，BN+CB 组表现出更多的功能失调人格特征和更高的一般精神病理学。与对照组相比，临床组总体表现出更高水平的精神病理学。
本研究结果表明，具有冲动特征的障碍（CB、GD、BN+CB 和 BN-CB）在一般精神病理学和特定人格特征方面呈线性趋势，但在特定人格和精神病理学维度上存在差异。
