The purpose of the study was to examine personality, sensation seeking
needs and risk taking in the Norwegian Everest expedition of 1985 whe
re all 7 members except one reached the top. Norwegian elite climbers,
n = 38, spouts students, n = 43, and military recruits, n = 26, were
used as reference groups. The results on Cattell II; PF showed the exp
edition members to be strong in drive factors (E+, M+, Factor IV), wea
k in stop-factors (G-, O-, Q4-, Factor I-) and with good stability (C, Q1+, Q2+). In relation to Zuckerman's Sensation Seeking Scale V (SSS
V) the expedition members had very high sensation seeking scores on t
hree of four subscales (TAS, ES, BS) and in total score. In general th
e expedition had more extreme scores than other climbers on relevant s
cales of Cattell 16 PF and SSS V. They were more willing to take risks
(Breivik Risk Test 5) than sports students in situations related to e
conomical, political/military and physical matters, but not in achieve
ment-related intellectual and social matters. It is concluded that the
re is a definite high risk athlete profile that may be identified both
on move general personality tests, move specific and relevant trait t
ests and on risk taking questionnaires.
