Differences in depressive symptoms between traditional workers and shiftworkers

Shiftwork causes a number of physical and psychological problems. As a result, we predicted depression to be worse for shiftworkers than for workers with more traditional schedules. In addition, we predicted that women would report more depressive symptoms than men as is the case in the general population. Questionnaire packets which included the Beck Depression Inventory were mailed to 153 workers in a small community. Analysis showed that, contrary to expectation, shiftworkers as a group suffered no more depressive symptoms than traditional workers. However, while both sexes had similar mean scores on depression among the shiftworkers, women were significantly more depressed than men among traditional workers.
