Identification of personality traits in anaesthetists has potential implica
tions for selection of trainees, assessment of coping strategies during tim
es of stress and may have a role in the analysis of critical incidents. A 2
4 question postal questionnaire based on the Cattell 16PF inventory was sen
t to specialist anaesthetists in Australia. One hundred and sixty-seven rep
lies were received (33% response rate). Personality traits did not differ w
hen the anaesthetists were grouped for age, number of years qualified and c
ountry of qualification. City practitioners rated themselves more inquisifi
ve than country practitioners did (P=0.052). Female anaesthetists self-repo
rted they were calm (P=0.02), patient (P=0.02) and tolerant (P=0.02) more o
ften than their male counterparts, whilst more males reported themselves as
highly conscientious (P=0.01), Although some traits were consistent, perso
nality profiles showed significant heterogeneity. Further examination of ho
w personality and coping mechanisms interact may be central to the manageme
nt of stress and critical incident generation.
