Component loadings for cortisol indices of depressed and older adult individuals during the Trier Social Stress Task, using oblimin rotation.

Cortisol variable	Depressed (N = 48)		Older adults (N = 51)
Component 1	Component 2	Component 1	Component 2
Baseline	.90	−.28	.96	−.30
20 min	.89	.50	.85	.36
40 min/45 min	.74	.69	.73	.56
Minimum	.93	.10	.95	−.034
AUCG	.93	.45	.91	.31
AUCI	.27	.95	−.009	.95
RT	.050	.98	−.068	.98
PkRT	.31	.90	.27	.88
Slp	.050	.98	−.10	.98
Int	.95	−.092	.93	−.33
% change	−.12	.91	−.093	.91

Note. Only component loadings greater than 0.4 are bolded. Baseline = baseline cortisol value; 20 min = cortisol value at 20 min post-challenge; 40 min = cortisol value at 40 min post-challenge; Min = minimum cortisol value; AUC_G = area under the curve with respect to ground; AUC_I = area under the curve with respect to increase; RT = reactivity; PkRT = peak reactivity; Slp = slope from baseline to 40 min value; Int = intercept of the regression line fitted through the raw cortisol data; % change = percent increase/decrease from 0 to 40 min.
