Cortisol, alpha amylase, and SUDS response to the TSST in CHR and control groups. Trier Social Stress Test (TSST), minutes are in relation to the start of the stressor, anticipation = time between instructions, and stressor; Error bars represent standard error of the mean. (A) Salivary cortisol response measured in μg/dl; −40 timepoint dropped from analysis to exclude potential confounds of travel; Omnibus effect significant (p < 0.05) for between group differences. (B) Salivary alpha amylase response measured in U/ml; Omnibus effect significant (p < 0.05) increase in both groups; *p < 0.05 for post-hoc group difference. (C) Subjective psychological response during the TSST measured with the Subjective Unites of Distress Scale (SUDS; 1 = not stressed at all, 100 = extremely stressed); Significant group by time interaction (p < 0.05); *p < 0.05 for post-hoc group difference.
