痛苦耐受力差（DT）被认为是焦虑，抑郁和其他一些心理障碍的潜在方面。正念可以通过培养一种接受或不评判痛苦经历的态度来帮助增加DT。因此，本研究探讨了简短的正念训练对不同类型的痛苦的耐受性的影响，并测试了特质正念是否会调节这种训练的效果。对正念不敏感的本科生（n = 107）在完成15分钟的正念训练或无指导控制（参与者听放松的音乐）之前和之后完成了一系列的压力任务（冷加压，过度换气挑战，中和任务）。与对照组相比，正念条件下的参与者在过度换气任务上表现出更大的任务持久性，并且减少了中和写令人不安的句子的影响的冲动。整体特质正念并没有显着缓和任务的持久性，但那些分数较低的行为与意识方面的正念表现出更大的相对效益的正念训练过度换气的挑战。中介分析显示，显着的间接影响，正念训练冷加压任务的持久性和敦促通过使用的nonjudge和nonreact方面的正念中和。这些结果表明，简短的正念训练可以增加DT，而不会影响主观的痛苦体验。
Poor distress tolerance (DT) is considered an underlying facet of anxiety, depression, and a number of other psychological disorders. Mindfulness may help to increase DT by fostering an attitude of acceptance or nonjudgment toward distressing experiences. Accordingly, the present study examined the effects of a brief mindfulness training on tolerance of different types of distress, and tested whether trait mindfulness moderates the effect of such training. Undergraduates (n = 107) naive to mindfulness completed a measure of trait mindfulness and underwent a series of stress tasks (cold pressor, hyperventilation challenge, neutralization task) before and after completing a 15-minute mindfulness training or a no-instruction control in which participants listened to relaxing music. Participants in the mindfulness condition demonstrated greater task persistence on the hyperventilation task compared to the control group, as well as a decreased urge to neutralize the effects of writing an upsetting sentence. No effect on distress ratings during the tasks were found. Overall trait mindfulness did not significantly moderate task persistence, but those with lower scores on the act with awareness facet of mindfulness demonstrated greater relative benefit of mindfulness training on the hyperventilation challenge. Mediation analyses revealed significant indirect effects of mindfulness training on cold pressor task persistence and urges to neutralize through the use of the nonjudge and nonreact facets of mindfulness. These results suggest that a brief mindfulness training can increase DT without affecting the subjective experience of distress.
