The data on psychological adaptation during polar winter-overs in Sub-Antarctic and Antarctic stations

The data presented in this article relate to the research article entitled “assessing psychological adaptation during polar winter-overs: The isolated and confined environments questionnaire (ICE-Q)” [1]. These data were acquired in order to develop a standardized instrument – the ICE-Q – designed to assess psychological adaptation within isolated, confined, and extreme environments. A total of 140 winterers from several sub-Antarctic (Amsterdam, Crozet, Kerguelen) and Antarctic (Concordia, Terre Adélie) stations voluntarily participated. Data were collected by multiple self-report questionnaires including a wide variety of well-known and validated questionnaires to record the winterers’ responses to polar stations. Data were gathered across two or three winter seasons within each of the 5 polar stations to ensure sufficiently large sample. From four to seven measurement time along a one-year period were proposed to the participants, resulting in 479 momentary assessments. Results of exploratory factor analyses, confirmatory factor analyses, exploratory structural equation modelling, reliability analyses, and test-retest provided strong evidence for the construct validity of the ICE-Q (19–item 4-factor questionnaire). The four factors were social, emotional, occupational and physical. Future studies would examine the dynamic of psychological adaptation in isolated, confined and/or extreme environments during polar missions.

Data
The data presented in this article is complementary to the research article entitled "assessing psychological adaptation during polar winter-overs: The isolated and confined environments questionnaire (ICE-Q)" [1]. A total of 140 winterers (Mage ¼ 34.42 ± 13.34 years, 17.9% of females) voluntarily participated. Participants were members of 14 distinct polar missions from several sub-Antarctic (Amsterdam, Crozet, Kerguelen) and Antarctic (Concordia, Terre Ad elie) stations. Data were gathered during several winter seasons and in several polar stations to ensure sufficiently large sample (no winterer participated in more than one winter season). Table 1 detailed the year of data gathering, the place of the polar mission and the number of participants. Table 2 indicates the initial questionnaire with the content of the items except the questionnaire protected by copyright.
Results of exploratory factor analysis with varimax rotation including all the items of the preliminary version of the ICE-Q are presented in Table 3. A four-factor solution was computed based on the scree test (the first four eigenvalues were substantially higher than the fifth one). Results of confirmatory factor analysis and exploratory structural equation modelling of the final 4-factor 19-item solution of the ICE-Q are presented in Figs. 1 and 2 respectively. The four factors emerging from exploratory and confirmatory factor analyses were social (a ¼ 0.82, r test-retest over a 5-month period ¼ .65), emotional (a ¼ 0.85, r ¼ 0.60), occupational (a ¼ 0.82, r ¼ 0.78) and physical (a ¼ 0.78, r ¼ 0.49).
Specifications Table   Subject Applied Value of the Data The data provides a short, quick, cost-effective and non-invasive measure to monitor psychological adaptation within the four key domains (social, emotional, occupational and physical) in isolated, confined and extreme environment. The data can help psychologists' to monitor psychological adaptation in extreme environment and to assist individuals optimizing their well-being and performance in such isolated, confined and extreme environment. The data can help researchers for understanding of factors influencing the adaptation to isolated, confined and extreme environment.
The findings of the present data call for further research to examine the dynamic of psychological adaptation in extreme environment.
Tables 4 and 5 displays the means and standard deviations of all the study variables for the 14 polar missions in sub-Antarctic stations (Amsterdam, Crozet and Kerguelen) and Antarctic stations (Concordia and Terre Ad elie) respectively. Based on the rationale that the present paper focused on the presentation and description of the data, all the psychological variables were averaged (representing the mean score of the several measurement points) in order to obtain a unique score of each psychological construct for each of the 14 polar missions. Finally, the final version of the ICE-Q is included in Table 6.

Experimental design, materials, and methods
Participants were winterers from several sub-Antarctic and Antarctic stations. The study protocol was carried out in accordance with the Declaration of Helsinki and was approved by the European space agency, the Paul Emile Victor institute and the local institutional review board. After comprehensive verbal and written explanations of the study, all the subjects gave their written informed consent to participate. Participants were asked to return the completed questionnaires directly to the researchers within two days after receiving the battery in their personal email account. The questionnaires were sent and returned the first days that the respondents were on site and at 3, 5, 6, 8, 10, and/or 12 months into the mission.
A battery of well-known and validated questionnaires was used to record the winterers' responses to polar stations. Because of the high workloads and psychological challenges of isolated, confined and extreme environments, shortened versions of the original scales were sometimes used. Participants completed the group environment scale (GES) [2] measuring cohesiveness, implementation and preparedness, and counterproductive activity, the job content questionnaire (JCQ) [3] assessing decision latitude, psychological job demands, social support from colleagues and supervisor, the Recovery Stress Questionnaire (RESTQ) [4] measuring balance between stress and recovery from physical, emotional, behavioral, and social perspectives, the boredom proneness scale (BPS) [5] assessing constraint, affective responses, perception of time, external and internal stimulation, the free time boredom scale (FTBS) [6] measuring the individual's perception of boredom in periods of leisure, the mindfulness attention awareness scale (MAAS) [7] assessing the cognitive, emotional, physical, and interpersonal domains of awareness in the present moment, the environment mastery scale and personal growth scale, retrieved from psychological well-being scales (PWBS) [8] assessing the capacity to effectively manage one's life and the surrounding environment and the individuals' perception of continuing personal development and openness to new experiences, a short questionnaire measuring primary and secondary appraisals [9], The brief COPE [10] assessing a wide variety of coping strategies used to deal with stress (acceptance, active coping, behavioral disengagement, denial, humor, planning, positive reframing, religious, self-blame, self-distraction, substance use, using emotional support, using instrumental support and venting), the defense style questionnaire [11] assessing a wide variety of  Counterproductive Activity GES Group members are engaged in petty quarrels with one another 49 Counterproductive Activity GES The atmosphere of the group is often hostile 50 Counterproductive Activity GES       individual's conscious derivatives of defense mechanisms (acting-out, altruism, anticipation, denial, devaluation of other, displacement, dissociation, fantasy, humor, idealization, isolation, passive aggressive, projection, rationalization, reaction formation, repression, splitting of other, sublimation, suppression, undoing), the Beck depression inventory-II [12] measuring depressive symptoms such as sadness, crying, and indecisiveness, and the life orientation test-revised [13] assessing dispositional optimism. It is noteworthy that the items of the preliminary version of the ICE-Q were comprised of the GES, JCQ, RESTQ, BPS, FTBS, MAAS, and PWBS items.
