The effects of gender, long-term need for recovery and trait inhibition-rumination on morning and evening saliva cortisol secretion

Abstract

The aim of this study was to investigate the long-term effects of need for recovery from work and trait rumination on saliva cortisol secretion. The sample consisted of 76 white-collar workers, 52 men and 24 women who had previously provided baseline data four years earlier and volunteered to participate in the present study. In the present study, saliva cortisol secretion was measured over seven consecutive days, on awakening, and at 10 p.m. No relationships were found between the independent variables and morning saliva cortisol levels. High trait rumination at baseline, however, was significantly related to higher evening cortisol levels for both women and men. Baseline need for recovery from work was strongly related to evening cortisol secretion for women, but in the opposite direction than expected. The present results add to the small but equivocal body of literature that has examined the long-term effects of work strain on cortisol secretion.
