Effects of stress on chewing and food intake in patients with anorexia nervosa
OBJECTIVE The present study investigates the impact of psychosocial stress on chewing and eating behavior in patients with anorexia nervosa (PAN ). METHOD The eating and chewing behavior of PAN were examined in a standardized setting by means of a chewing sensor. These procedures encompassed n = 19 PAN , age, and gender matched to n = 19 healthy controls (HC). Food intake and chewing frequency were assessed in two experimental conditions: rest versus stress (via Trier Social Stress Test). To verify stress induction, two appraisal scales were employed. In addition, chronic stress, psychological distress and eating disorder symptoms were assessed. RESULTS In terms of food intake and chewing f…
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…
