Cortisol reactivity in social anxiety disorder: A highly standardized and controlled study.

Abstract In order to understand the psychopathology of the social anxiety disorder (SAD) at the neuroendocrine level, standardized experimental studies on endocrine and physiological markers are necessary, especially since empirical data are still ambiguous. Hence, differences in both, the autonomic nervous system (ANS) and the endocrine stress responses (ACTH, salivary and plasma cortisol) were investigated in a particularly homogenous sample after a standardized stressor (Trier Social Stress Test). The sample consisted of n  = 35 patients with SAD, age, and gender matched to n  = 35 healthy controls (HC). In terms of the heart rate, the response pattern was comparable in both groups. Conc…
