Teacher stress over an autumn term: relationships between subjective stress and catecholamine excretion during night rest

The relationships between subjective stress and catecholamine excretion during night rest were investigated in a group of 137 teachers. The research design was longitudinal and consisted of repeated assessment (six times in an autumn term) of the stress indicators. At the beginning of the term adrenaline excretion rate showed negative and at the end of the term positive correlations with subjective stress feelings. Cluster analysis revealed three stable profile types among the teachers, in which the stress indicators were related to each other in different ways. The subjective stress process was better reflected in noradrenaline excretion than in adrenaline excretion. The findings were interpreted to reflect the changes in the intensity of emotional arousal during the term.
