Research suggests that negative affect, negative urgency, and thought suppression are related to bulimic symptoms, either directly or indirectly. This study examined associations between these constructs in a sample at-risk for bulimic symptoms. Participants (N = 80) recruited from a residential substance abuse treatment facility completed self-report questionnaires. A regression-based bootstrapping approach was used to examine the indirect effect of negative affect on bulimic symptoms through negative urgency and the moderating role of thought suppression in the association between negative affect and negative urgency. Results revealed a significant indirect effect, significant moderation, and a significant moderated mediation effect, with an indirect effect of negative affect on bulimic symptoms through negative urgency, conditional upon low to moderate (but not high) levels of thought suppression. These findings suggest that negative affect may promote rash actions, particularly in the context of low to moderate thought suppression, leading to increased risk of bulimic symptoms.
研究表明，消极情绪、消极紧迫感和思维抑制与暴食症状直接或间接相关。本研究在有暴食症状风险的样本中检验了这些构念之间的关联。从一家住院药物滥用治疗机构招募的参与者（N = 80）完成了自我报告问卷。采用基于回归的自抽样法来检验消极情绪通过消极紧迫感对暴食症状的间接影响，以及思维抑制在消极情绪与消极紧迫感关联中的调节作用。结果显示出显著的间接效应、显著的调节作用和显著的调节中介效应，消极情绪通过消极紧迫感对暴食症状的间接效应在低至中等（但非高）水平的思维抑制条件下显著。这些发现表明，消极情绪可能会促发冲动行为，尤其是在低至中等思维抑制的情况下，从而增加出现暴食症状的风险。
