Abstract
BackgroundLong-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. MethodsTwenty-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. ResultsResults 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. ConclusionsMindfulness 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.
