Personality stability and adjustment to an extreme environment

Abstract

Administered the MMPI and the Personality Research Form to 15 volunteer Antarctic explorers before, in the middle of, and after an 8.5-mo period of isolation, and to 30 male undergraduates on 2 occasions 8 mo apart. Results suggest that the explorers were generally better adjusted, more achievement oriented, more self-sufficient, and more serious minded than the undergraduates. No changes in personality profiles were observed on retesting. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
