Abstract：
Boredom, a complex emotional state with implications for mental health and well-being, has garnered attention across disciplines, yet remains relatively understudied in psychiatric research. Here, we explored the intricate relationship between trait-impulsivity, stress, and boredom across two studies. Participants completed self-report measures of trait-impulsivity and boredom and boredom-inducing tasks. Study 1, involving 80 participants (42 women and 38 men, aged 20-63), replicates previous findings, by demonstrating that impulsive individuals report greater boredom following a boring task. Study 2 then extends this, using 20 participants (9 women and 12 men, aged 18-24), to show that hypothalamic-pituitary-adrenal (HPA) axis activity, specifically heightened salivary cortisol responses, mediate the link between impulsivity and boredom following a boring task. Collectively, these results demonstrate that HPA axis activity may underline the relationship between trait-impulsivity and boredom by extending previous work and offering a novel insight into potential mechanisms. These findings offer promise for personalised interventions, designed for high impulsivity individuals, to alleviate the negative impacts of boredom and potentially break the identified feedback loop.
摘要：
无聊，一种复杂的情绪状态，对心理健康和幸福有影响，引起了跨学科的关注，然而，在精神病学研究中，研究仍相对不足。这里,我们探索了特质与冲动之间的复杂关系，压力，以及两项研究的无聊。参与者完成了特质冲动，无聊和无聊诱导任务的自我报告措施。研究1，涉及80名参与者(42名女性和38名男性，20-63岁)，重复了以前的发现，通过证明冲动的人在无聊的任务后报告更大的无聊。然后研究2扩展了这一点，使用20名参与者(9名女性和12名男性，18-24岁)，显示下丘脑-垂体-肾上腺（HPA）轴活动，特别是唾液皮质醇反应增强，在无聊的任务之后，调解冲动和无聊之间的联系。总的来说，这些结果表明，HPA轴活动可能通过扩展先前的工作并提供对潜在机制的新见解来强调特质冲动性和无聊之间的关系。这些发现为个性化干预提供了希望，专为高度冲动的人设计，以减轻无聊的负面影响，并可能打破已确定的反馈循环。
