Brief Summary:
Stress is a complex natural phenomenon, frequently related to a physiological response, including heart rate, heart rate variability, respiratory rate, skin conductance and temperature. The subjective experience varies greatly; broadly, it may be conceived as a freeze, flight, fight, fright or faint response. Many studies have demonstrated the negative influence of psychological stress on health and well-being. Through the digital phenotyping of physiological and psychological stress reactions, in a controlled laboratory setting (Trier Social Stress Test- TSST) and real-life situations, in a population of healthy participants and patients with a major psychiatric disorder, we expect to find reliable and valid digital biomarkers. The results of this study will, therefore, not only contribute to a better understanding of stress and stress response but also have the potential to improve diagnostic and treatment approaches.

Arm Intervention/treatment
Experimental: TSST Behavioral: Trier Social Stress Test
The TSST-G is a psychological paradigm which combines high levels of social-evaluative threat and uncontrollability in a group setting. The TSST-G will proceed in groups of three to five participants (from the same diagnostic group). The TSST-G consists of three phases: a briefing; the psychological test itself, followed by a debriefing phase. Each phase will last 40, 20 and 60 minutes, respectively. The briefing and debriefing of the TSST-G will be conducted by experienced psychotherapists. The TSST-G itself will be conducted by personal unknown to the participants.
