Cardiovascular responses to social stress elicited by the cyberball task

Objective: The aim of the current study was to investigate cardiovascular responses to a brief social exclusion stressor, the Cyberball task, and to determine whether individual differences in depression, anxiety, and perceived social isolation moderate physiological stress responses. Methods: Sixty-four participants engaged in the Cyberball task while heart rate, blood pressure, and respiratory rate were continuously measured. Results: Systolic (M = 121.61, SD = 13.34) and diastolic (M = 77.34, SD = 7.56) blood pressure increased significantly during the exclusion condition compared with the rest condition (M = 117.81, SD = 12.71, M = 75.63, SD = 7.39, respectively). Significant correlations were also found between social anxiety (r = -0.25) and depression (r = -0.25) scores with systolic blood pressure from the exclusion condition. Further, participants who reported high depression scores had attenuated cardiovascular responses to social exclusion. Conclusions: Overall, cardiovascular activity were elevated after a brief social stressor, but those with clinically relevant cut off scores on the CES-D had attenuated cardiovascular responses These findings support the growing body of literature surrounding cardiovascular stress reactivity to stress induced from social exclusion.
