Recent research has highlighted the utility of using revised Reinforcement Sensitivity Theory (RST) to further understand the individual differences that influence binge eating behaviours. The current study draws on both RST and theoretical models that implicate negative affect in binge eating, with the aim of identifying indirect pathways between individual differences in RST systems and binge eating as mediated through negative affect. Undergraduate students (n = 229, M = 22.67 years of age, SD = 8.95, 76% female) completed self-report measures of revised reinforcement sensitivities, negative affect and binge eating symptoms. Bootstrapped tests of indirect effects showed that negative affect mediated the pathway between the Behavioural Inhibition System (BIS) and binge eating symptoms. Additionally, negative affect mediated the pathway between rash impulsivity and binge eating symptoms. This study supports and extends previous research by highlighting the experience of negative affect as a possible mechanism through which heightened BIS and rash impulsivity leads to binge eating.

最近的研究突出了使用修订后的增强敏感性理论（RST）来进一步了解影响暴饮暴食行为的个体差异的实用性。当前的研究借鉴了RST和理论模型，这些模型暗示了暴饮暴食的负面影响，目的是确定RST系统中个体差异与通过消极情绪介导的暴饮暴食之间的间接途径。本科生（n  = 229，M  = 22.67岁，SD = 8.95，76％的女性）完成了自我报告的措施，修正了强化敏感性，负面影响和暴饮暴食症状。间接影响的引导测试表明，负面影响介导了行为抑制系统（BIS）与暴饮暴食症状之间的通路。此外，负面影响介导了皮疹冲动和暴饮暴食症状之间的途径。这项研究通过强调负面影响的经验来支持和扩展以前的研究，负面影响是增加BIS和皮疹冲动导致暴饮暴食的一种可能机制。
