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.
