BackgroundThe nature and significance of impulse-control difficulties in binge-eating disorder (BED) are uncertain. Most emerging research has focused on food-specific rather than general impulsivity. The current study examines the clinical presentation of patients with BED categorized with and without clinical levels of general impulsivity.MethodA total of 343 consecutive treatment-seeking patients with BED were categorized as having BED with general impulsivity (GI+; N = 73) or BED without general impulsivity (GI−: N = 270) based on structured diagnostic and clinical interviews. The groups were compared on demographic, developmental, and psychological features, and on rates of psychiatric and personality comorbidity.ResultsIndividuals with BED and general impulsivity (GI+) reported greater severity of eating-disorder psychopathology, greater depressive symptoms, and greater rates of comorbidity than those without general impulsivity (GI−).ConclusionsA subtype of individuals with BED and general impulsivity may signal a more severe presentation of BED characterized by heightened and broader psychopathology. Future work should investigate whether these impulse-control difficulties relate to treatment outcomes.

暴食症的一般冲动

背景暴食症（BED）中冲动控制困难的性质和意义尚不确定。大多数新兴研究都集中在特定食物而不是一般冲动上。目前的研究检查了 BED 患者的临床表现，分为有和没有一般冲动临床水平。方法总共 343 名连续寻求治疗的 BED 患者被分类为有一般冲动性 BED (GI+; N = 73) 或没有 BED基于结构化诊断和临床访谈的一般冲动性（GI-：N = 270）。在人口统计学、发育和心理特征以及精神和人格共病率方面对各组进行了比较。与没有一般冲动（GI-）的人相比，抑郁症状和合并症的发生率更高。结论 患有 BED 和一般冲动的个体的亚型可能预示着 BED 的更严重表现，其特征是更高和更广泛的精神病理学。未来的工作应该调查这些冲动控制困难是否与治疗结果有关。
