For people suffering from social anxiety disorder (SAD), social
interactions imply severe distress. Nonetheless, little is known about
the social-interactional effects of stress and the stress-related
psychobiology in SAD. The thesis presents the findings of a research
project on the social-interactional consequences of acute stress in SAD
patients. In contrast to healthy controls, SAD patients did not exhibit
increased affiliation behavior under stress, but rather showed reduced
prosocial behavior. Furthermore, the findings suggest that cognitive
empathy modulates SAD patients' way of dealing with social stress. The
results extend previous data in the domain of stress reactivity and
social behavior in social anxiety and provide leverage points for future
studies.
