Note. Participants N = 151; N = 558 days; CAR = cortisol awakening response; DEC = daily decline; AUC = area under the curve; VAR = variance.
Support was coded 0 = no support given, 1 = support given.
Gender was coded 0 = female, 1 = male.
Employment status was coded 0 = not working full-time, 1 = employed full-time.
Neuroticism was calculated averaging ratings of four items (e.g., moody, worrying, nervous, calm) from 1 = not at all to 5 = a great deal.
Health status was rated from 1 = poor to 5 = excellent.
Weekend day was coded 0 = weekday, 1 = weekend day.
Sleep quality night before was rated from 1 = poor to 5 = excellent.
Smoked this day was coded 0 = no, 1 = yes.
Medication day was coded 0 = no, 1 = yes.
