Abstract: Background:There are large individual differences in dealing with everyday social stress. Therefore, we in-vestigated the association of social inhibition (and its facets) with the emotional and physiological responses tothe Trier Social Stress Test (TSST).Methods:Undergraduate students (N= 312) completed the 15-item Social Inhibition Questionnaire (SIQ15) andparticipated in the TSST, while emotional and cardiovascular stress responses were recorded. We examined theeffect of social inhibition across time with repeated-measures ANCOVAs.Findings:During social stress (and recovery), social inhibition was associated with increased negative moodreactivity (especially the behavioral inhibition facet) and heightened sympathetic activation (especially thesocial withdrawal and interpersonal sensitivity). Physiological stress reactivity seems to be mostly?-adrenergicin women, and also?-adrenergic in men.Conclusions:Emotional and physiological stress responses are associated with individual differences in socialinhibition. This warrants more research on mechanisms that underlie the relations between social inhibition,stress and health.
