Note. N = 202; due to missing cortisol values.
p < .001.
As part of parent study, participants experienced two acute stress lab sessions; speech topics were counterbalanced across visits and included shoplifting or traffic violation.
SLEs = Stressful Life Events experienced in the last 12 months; RSs = Social Relationship Stressful Events in the last 12 months; S.E. = standard error; HM = Hormonal medication; BMI = Body Mass Index. The interaction term is the product of the mean center ST and Sup variables.
