The origin and type of stress among seamen were investigated by means
of interviews with three harbor physicians in Rotterdam. The main psyc
hological problems encountered were loneliness, homesickness, and ''bu
rn-out'' syndrome. The problems were primarily caused by long periods
away From home, the decreased number of seamen per ship, and by increa
sed automatization. Quantification of the prevalence and severity of t
hese problems is necessary to elucidate preventive and therapeutic mea
sures.
