Individual Differences in Adaptability to Isolated, Confined, and Extreme Environments

Area of Science:

• Space exploration
• Human factors in extreme environments
• Psychology of adaptation

Background:

• Deep space missions present unprecedented stressors, including prolonged isolation and reduced Earth support.
• Astronauts must function autonomously in confined and extreme environments.
• Effective astronaut selection and training are critical for mission success.

Purpose of the Study:

• To systematically review literature on individual adaptability to isolated, confined, and extreme (ICE) environments.
• To identify key cognitive and behavioral factors linked to successful adaptation in such conditions.

Main Methods:

• A systematic literature search was conducted across major scientific databases (PubMed, Embase, Web of Science, PsychINFO).
• Studies were evaluated for quality and relevance to long-duration space missions.
• Key findings regarding adaptability attributes were extracted.

Main Results:

• 73 studies met the inclusion criteria for the review.
• Key adaptability attributes identified include intelligence, emotional stability, self-control, openness, conscientiousness, optimism, mastery, introversion, hardiness, task-oriented coping, prior experience, low need for social support, and adequate sleep.
• These factors are crucial for functioning in isolated, confined, and extreme environments.

Conclusions:

• This review synthesizes individual factors contributing to adaptability in isolated, confined, and extreme environments.
• Further research is necessary to establish causal relationships and the relative importance of these attributes.
• Findings can inform astronaut selection and training protocols for future space missions.
