Binge eating has a high prevalence among bariatric patients and is associated with post-surgical weight gain. This study examined the potential mediating role of emotion regulation difficulties in the relation between attachment insecurity and binge eating among this population. Participants were 1388 adult pre-bariatric surgery candidates from an accredited bariatric surgery assessment centre in Toronto, Ontario. Participants completed measures of psychological functioning, including attachment style and emotion regulation. Mediation analyses revealed that difficulties with emotion regulation mediated a positive association between insecure-anxious attachment and binge eating. An insecure-avoidant attachment was found to have a non-significant association with binge eating when examining the total effect. However, when difficulties with emotion regulation were controlled for in the model to examine its role as a mediator, this association became significant, and emotion regulation difficulties also mediated the relationship between attachment avoidance and binge eating. These findings suggest that difficulties in emotion regulation may be an important clinical issue to address in order to reduce binge eating in adult bariatric surgery candidates.
暴食在肥胖症患者中较为常见，且与手术后体重增加有关。本研究旨在探讨在该人群中，依恋不安全感与暴食之间的关系中，情绪调节困难的潜在中介作用。参与者为来自安大略省多伦多市一家经认证的肥胖症手术评估中心的 1388 名成人肥胖症手术前候选者。参与者完成了心理功能的测量，包括依恋风格和情绪调节。中介分析显示，情绪调节困难在不安全-焦虑依恋与暴食之间存在积极的关联中起中介作用。当考察总效应时，发现不安全-回避依恋与暴食之间存在非显著关联。然而，当在模型中控制情绪调节困难以考察其作为中介的作用时，这种关联变得显著，并且情绪调节困难也介导了回避依恋与暴食之间的关系。这些发现表明，情绪调节困难可能是解决成人肥胖症手术候选者暴食问题的一个重要临床问题。
