A longitudinal questionnaire study of 314 medical students followed up as p
reregistration house officers (PRHOs) and again 7 years later showed labora
tory-based doctors were the least happy with their choice of career and wer
e the most stressed now, while surgeons were the most happy with their choi
ce and the least stressed. These differences were apparent 10 years earlier
The study also describes perceived influences on specialty choice and expl
ores how earlier factors, such as personality as students and stress in the
PRHO year, may also have influenced specialty choice.
