Shiftwork tolerance and 24-hour variations in moods
The objective of the study was to identify the differences in 24-hour variations in moods between the three groups of oil-refinery workers: tolerant shiftworkers, intolerant shiftworkers and the workers who had never worked in shifts. Each examined group involved 29 workers matched by age. The mood measurements were taken during a 24-hour period every two hours starting from 08:00. Results were scored for three scales: positive moods, negative moods and fatigue. The two-factor ANOVA revealed the significant main effect of groups for all three moods indicating differences at the average level of 24-hour variations in all moods between workers who differed in the degree of the tolerance to shiftwork. The significant main effect of time of day was also found for all moods while the reliable interaction between groups and time of day was observed for negative moods only, indicating a different shape of 24-hour variations for non-shiftworkers in comparison to shiftworkers.
