Extreme environmental situations are useful tools for the investigation of the general processes of adaptation. Among such situations, high altitude of more than 3000 m produces a set of pathological disorders that includes both cerebral (cAS) and respiratory (RAS) altitude symptoms. High altitude exposure further induces anxiety responses and behavioural disturbances. The authors report an investigation on anxiety responses, personality traits, and altitude symptoms (AS) in climbers participating in a 31-day period of confinement and gradual decompression in a hypobaric chamber equivalent to a climb from sea-level to Mount Everest (8848 m altitude). Personality traits, state-trait anxiety, and AS were assessed, using the Cattell 16 Personality Factor questionnaire (16PF), the Spielberger's State-Trait Anxiety Inventory (STAI), and the Lake Louise concensus questionnaire. Results show significant group effect for state-anxiety and AS; state-anxiety and AS increased as altitude increased. They also show that state-type anxiety shows a similar time-course to cAS, but not RAS. Alternatively, our results demonstrate a significant negative correlation between Factor M of the 16PF questionnaire, which is a personality trait that ranges from praxernia to autia. In contrast, no significant correlation was found between personality traits and AS. This suggests that AS could not be predicted using personality traits and further support that personality traits, such as praxernia (happening sensitivity), could play a major role in the occurrence of state-type anxiety responses in extreme environments. In addition, the general processes of coping and adaptation in individuals participating in extreme environmental experiments are discussed.

在 31 天的低压室缺氧期间的焦虑、个性和海拔症状研究（实验“Everest-COMEX 1997”）

极端环境情况是调查一般适应过程的有用工具。在这些情况中，海拔超过 3000 m 会产生一系列病理障碍，包括脑 (cAS) 和呼吸 (RAS) 海拔症状。高海拔暴露进一步诱发焦虑反应和行为障碍。作者报告了一项关于登山者的焦虑反应、人格特征和海拔症状 (AS) 的调查，这些登山者在相当于从海平面攀登珠穆朗玛峰 (8848 m) 的低压舱中进行 31 天的监禁和逐渐减压。高度）。使用 Cattell 16 人格因素问卷 (16PF)、斯皮尔伯格的状态-特质焦虑量表 (STAI)、和路易斯湖人口普查问卷。结果显示，状态焦虑和 AS 的群体效应显着；状态焦虑和 AS 随海拔升高而增加。他们还表明，状态型焦虑显示出与 cAS 相似的时间过程，但与 RAS 不同。或者，我们的结果表明 16PF 问卷的因子 M 之间存在显着的负相关，这是一种性格特征，范围从 praxernia 到 autia。相比之下，在人格特质和 AS 之间没有发现显着的相关性。这表明无法使用人格特征预测 AS，并进一步支持人格特征，如 praxernia（发生敏感性），可能在极端环境中状态型焦虑反应的发生中起主要作用。此外，
