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.
最近的研究强调了使用修订后的强化敏感性理论（RST）来进一步理解影响暴食行为的个体差异的效用。本研究借鉴了 RST 和理论模型，这些模型暗示了消极情绪在暴食中的作用，目的是确定 RST 系统个体差异与暴食之间通过消极情绪中介的间接途径。本研究共纳入 229 名本科生（M=22.67 岁，SD=8.95，76%为女性），他们完成了修订后的强化敏感性、消极情绪和暴食症状的自我报告测量。间接效应的 bootstrap 检验显示，消极情绪中介了行为抑制系统（BIS）与暴食症状之间的关系。此外，消极情绪还中介了冲动性与暴食症状之间的关系。本研究通过强调消极情绪体验可能是增强的 BIS 和冲动性导致暴食的一种机制，支持并扩展了之前的研究。
