The purpose of the study was to investigate inter-shift differences and changes from the beginning to the end of shift-weeks on different shifts with regard to catecholamines, diuresis, and self-ratings of fatigue and other mood variables. A further aim was to study individual variations in these respects and their relation to attitudes towards the shift system. The main hypotheses were that catecholamine excretion, diuresis and subjective arousal are lower during the night shift than during the day shifts, these differences decrease after a few days on the same shift, i.e. an adaptation occurs, and individuals who have favourable attitudes towards shift work and the rota system do adapt to a greater extent than those with unfavourable attitudes.
