The study of winter-over polar stations has already made it possible to highlight some characteristics related to a good individual and social adaptation. It particularly appears that social aspects are determining when individuals live for a relatively long period in small isolated groups. Indeed, the constraints linked to isolation and confinement in a limited space facilitate the appearance of interpersonal or inter-group conflicts. It also appears that the presence of different professions and statutes harm the cohesion of the wintering group. In addition, the personal and professional occupations play a significant role in the well-being experimented by the wintering team: environmental and social monotony constitutes a major stress, source of personal, interpersonal and inter-group conflicts. However the physical environment, in spite of its monotony, is also a source of positive stimulations largely reported in many writings. A polar experience can thus be lived very positively. It seems that the diversity of the individual interests as well as professional ones can constitute an important element in the adaptation to such a situation. Indeed, winter-over situations constitute first of all professional experiences, and working is the principal reason of presence of the wintering teams. This is why we studied the professional interests and preferences as determinants of the adaptation.
