Brief Summary

The MINDFUL-ICE II project explores the significance of mindfulness as a psychological trait crucial for extended missions in isolated and confined environments (ICEs). Previous data from the MINDFUL-ICE study with Concordia base crews validated a link between dispositional mindfulness and reduced stress. However, the efficacy of a mindfulness-based intervention in mitigating distress and fostering psychological adaptation within such environments remains untested. This project aims to assess a specific mindfulness training program's efficacy, feasibility, and usability for Concordia base crews over a two-year assignment. The pre-departure online mindfulness training, tailored for the pre-mission period, will feature minimal time commitments. Bi-weekly booster sessions during the mission, conducted by the ESA MD, will support the training. Using a quasi-experimental design, crews receiving this intervention will be compared with the first MINDFUL-ICE study's results. Stress, mindfulness, and psychological data will be tracked throughout the winter-over mission, aligning with the assessment approach of the initial study. Participants will report program usage, acquired knowledge, and engage in post-mission qualitative interviews. Both quantitative and qualitative findings will be crucial in gauging the intervention's effectiveness and usability for future long-duration and ICE space missions.

Detailed Description

Long-duration space missions introduce unique stressors, including isolation, confinement, communication delays, and environmental monotony, which can negatively affect mood, cognition, and performance. This study addresses the need for countermeasures by testing a mindfulness-based training program developed specifically for such environments. The intervention includes:

Pre-departure Training: A three-week, self-paced online course delivered via the Qualtrics platform, featuring videos, audio content, and exercises. Participants engage in daily activities averaging 15-30 minutes, focusing on mindfulness principles such as awareness, flexibility, and creativity.

Mission Phase: Bi-weekly booster sessions led by the ESA physician, supplemented by ongoing access to training materials. Content is tailored to address the challenges of ICE settings and can be accessed on-demand.

Assessment: Stress and mindfulness levels are measured at multiple time points (pre-departure, mid-mission, and post-mission). Additional qualitative feedback will explore participant experiences, training usability, and psychological adaptation.

The quasi-experimental design compares the outcomes of MINDFUL-ICE II participants with data from the previous observational MINDFUL-ICE study, which serves as a control group. This approach leverages matched cohorts to evaluate the program's efficacy in reducing stress and fostering adaptive psychological responses.

Data will be collected using validated psychometric tools, including the Perceived Stress Scale (PSS), Mindful Attention Awareness Scale (MAAS), and Langer Mindfulness Scale (LMS), alongside qualitative interviews and thematic analysis. Insights gained will contribute to the development of psychological interventions for future space exploration missions and other high-stress, isolated environments.

Primary Outcome Measures

Name	Time	Method
Stress	Up to 12 months.	Stress will be assessed using the Perceived Stress Scale, a validated 10-item self-report measure. Individual scores on the scale can range from 0 to 40 with higher scores indicating higher perceived.

Secondary Outcome Measures

Name	Time	Method
Mindful Attention	Up to 12 months.	The Mindful Attention Awareness Scale: A 15-item self-report measure designed to assess a core characteristic of mindfulness, namely one's receptive awareness of and attention to what is taking place in the present. It has been validated in multiple languages, including Italian and French. The measure takes 5 minutes or less to complete. Based on a mean of all items, MAAS scores can range from 1 to 6. Higher scores indicate greater mindfulness.
Langerian Mindfulness	Up to 12 months.	The Langer Mindfulness Scale: A 21-item questionnaire that assesses three domains describing mindful thinking: novelty seeking, engagement, flexibility, and novelty producing. It has been translated and validated in Italian, and the French validation is currently ongoing. The LMS can be completed in less than 5 minutes. The score ranges from to 21 to 147, with higher scores reflecting higher mindfulness.
Mindul Creativity	Up to 12 months (baseline and post-mission assessments).	The Triangle Task assesses creative mindful thinking by asking participants to identify connections between abstract and concrete concepts (e.g., a "triangle" and related items). Scores reflect cognitive flexibility and openness. Scores range from 0 to 50, with higher scores reflecting higher mindful creativity.
