Abstract
- Background: Feeling alive and invigorated, or vitality, is examined within the framework of a stress paradigm. The current study investigated whether endocrine and cardiovascular responses to acute psychological stress predict declines in vitality. Methods: A sample of 90 undergraduate students completed an in-lab stressor. We measured anxiety, state vitality, cortisol levels, heart rate, and blood pressure before the task, and measured changes in state vitality, cortisol, heart rate, and blood pressure in response to the stressor. We investigated whether pre-task anxiety predicted changes in state vitality, and whether such changes were explained by physiological responses. Results: Results indicate that cognitive and somatic anxiety preceding a stressor predict changes in vitality, which is mediated by the magnitude of diastolic (95% CI [0.017, 0.517]; [0.006, 0.454]) and systolic (95% CI [0.038, 0.705]) blood pressure responses to the task. Cortisol reactivity was associated with somatic anxiety (F(6, 83) = 3.34, p <.01, β = 0.401) but was not related to changes in vitality. Conclusions: Together, these results contribute to the understanding of how physiological reactivity to a stressor can deplete vitality. [ABSTRACT FROM AUTHOR]
