Abstract : The relationship between group adaptation and individual adjustment has been the focus of recent research on the long-term effects of prolonged isolation in the Antarctic. A series of studies conducted at the Naval Health Research Center examined the health and service records of enlisted Navy personnel who applied to the Operation Deep Freeze Program between 1963 and 1974. The objective of these studies was to determine if follow-up incidence rates and performance criteria were significantly different between a group of winter-over personnel and a control group of enlisted personnel who were screened and qualified for winter-over duty but assigned elsewhere. Results indicated that the overall incidence rate for the winter-over group was significantly lower than the rate for the control group. An increase in total disease incidence was observed among the winter-over group within a year of their return from the Antarctic, but this increase failed to attain statistical significance relative to the rate of the control group. In addition, individuals with high needs for achievement and control over others were found to be at reduced risk for long-term disease incidence. These results are examined in light of personality traits which facilitate adjustment to stressful life events and the sociocultural systems of Antarctic stations which support and promote values enabling personnel to adapt to prolonged isolation.
