R. Szczepanski et al., RELATION OF MOOD RATINGS AND NEUROHORMONAL RESPONSES DURING DAILY-LIFE IN EMPLOYED WOMEN, International journal of behavioral medicine, 4(1), 1997, pp. 1-16
Diurnal variations in urinary norepinephrine, epinephrine, cortisol, a
nd self-reported mood states were examined in 101 employed women. Urin
e was collected on 2 consecutive workdays at 3 time periods: (1) overn
ight, (2) daytime, and (3) evening. Self-reports of 14 mood states wer
e combined to correspond with the urinary collection periods. Factor a
nalyses revealed 3 mood factors: Pressured (rushed, busy, stressed, ha
ssled, and tense), Distressed (afraid, depressed, bored, and nervous),
and Contented (satisfied, thoughtful, excited, and calm). The Distres
sed factor was significantly associated with norepinephrine excretion
(p <.001). The Pressured factor was significantly associated with cort
isol, epinephrine, and norepinephrine excretion (p <.001) independent
of age, ethnicity, marital status, parental status, department within
the company, and activity level. Secretion of urinary hormones and the
Pressured factor followed the same diurnal pattern. Specifically, as
women's self-ratings of feeling pressured initially increased and then
decreased over the course of the workday, urinary hormones also peake
d and then dropped. Once time of day was statistically controlled, how
ever, the mood factors were no longer significantly related to the uri
nary hormones.
