BACKGROUND: While depressed mood, insomnia, irritability and impaired cognition represent common responses to the physical and psychosocial stressors associated with polar environments, wide variations exist in their expression and the degree to which they adversely affect the health and performance of polar expeditioners. In particular, the process of successful adaptation to polar environments and the psychosocial characteristics associated with this process remains poorly understood.
HYPOTHESIS: Psychosocial characteristics associated with successful coping with typical stressors are also associated with successful adaptation in polar environments.
METHODS: The 4 men and 3 women participating in a 3-week scientific expedition in the Canadian High Arctic completed a battery of psychological questionnaires, including the Profile of Mood States (POMS), prior to their departure to Isachsen, N.W.T. In Isachsen, subjects completed the POMS and the Structured Interview Guide for the Hamilton Depression Rating Scale--Seasonal Affective Disorders Version (SIGH-SAD) each week.
RESULTS: Good psychological adjustment was demonstrated by a significant decline in POMS factor scores for tension-anxiety (p = 0.005), fatigue (p < 0.0001), and confusion (p = 0.024) from baseline to Week 3, and a significant decline in SIGH-SAD depressive symptoms (p < 0.0001) during Weeks 1-3. This is attributed to high levels of paratelic dominance and low levels of neuroticism, and use of planful problem-solving as a coping strategy more frequently than other coping strategies.
CONCLUSIONS: Improved psychological functioning among polar expeditioners reflects a combination of psychosocial characteristics that facilitate successful adaptation to any stressful experience, as well as characteristics specifically adaptive for living in polar environments.
