Long-duration missions in isolated, confined, and extreme environments, including Antarctica and upcoming deep-space operations, can be a source of increased stress. The identification of countermeasures and protective factors is required to support health and performance in similar contexts. Mindfulness disposition is an optimal candidate, but no research has ever explored this potential association. Twenty-four crew members from two Antarctic expeditions at the Concordia base were repeatedly assessed over the course of a 12-month mission for stress (Perceived Stress Scale) and mindfulness, using multiple assessment measures, including the Mindful Attention and Awareness Scale (MAAS), the Langer Mindfulness Scale (LMS), the Breath Counting Task, and the Triangle Task. Results indicate a strong negative association over time between mindfulness and stress, particularly when measured with the MAAS and the LMS. Higher MAAS baseline values were also good predictors of lower stress patterns during the mission. Mindfulness disposition was negatively associated with stress over time, suggesting that it can play an important role in stress mitigation in isolated and confined environments, including long-duration space missions. Furthermore, a mindfulness assessment could be added to the crew selection procedure.

正念倾向作为南极洲压力的保护因素：长期太空飞行的潜在对策？

在孤立、有限和极端的环境中执行长期任务，包括南极洲和即将到来的深空行动，可能会增加压力。需要确定对策和保护因素，以支持类似情况下的健康和绩效。正念倾向是最佳候选者，但还没有研究探索过这种潜在的关联。来自康科迪亚基地两次南极探险的 24 名船员在为期 12 个月的任务过程中接受了压力（感知压力量表）和正念的反复评估，使用了多种评估措施，包括正念注意力和意识量表 (MAAS) 、兰格正念量表 (LMS)、呼吸计数任务和三角任务。结果表明，随着时间的推移，正念和压力之间存在很强的负相关关系，特别是在使用 MAAS 和 LMS 进行测量时。较高的 MAAS 基线值也是任务期间较低压力模式的良好预测指标。随着时间的推移，正念倾向与压力呈负相关，这表明它可以在孤立和有限的环境中（包括长期太空任务）缓解压力方面发挥重要作用。此外，可以将正念评估添加到船员选拔程序中。
