Does well-being associate with stress physiology? A systematic review and meta-analysis

Abstract

Objective: The current meta-analysis tested whether trait indicators of well-being associate with stressor-evoked physiological reactivity and recovery in healthy adults.

Method: Medline, PsycINFO, and PubMed were used to identify relevant articles. Articles were included if they (a) measured cardiovascular or neuroendocrine (but not immune) physiology during or after an acute laboratory stress paradigm (b) measured indicators of hedonic well-being, eudaimonic well-being, or optimism, and (c) included healthy adult participants. Laboratory stress tasks included frustrating cognitive tasks, emotional recall tasks, and tasks involving social evaluation. Physiological variables were aggregated across cardiac (heart rate and cardiac output), hemodynamic (mean arterial pressure, systolic blood pressure, and diastolic blood pressure), HPA (cortisol), and autonomic (high frequency heart rate variability, skin conductance, and catecholamines) markers. Twenty-seven studies were included (n = 3,390; 54.6% women). Effect sizes and confidence intervals were estimated using a random-effects model with pooled variance.

Results: Contrary to expectations, optimism was associated with greater cardiac reactivity to cognitive stressors but did not associate with stress recovery. By contrast, hedonic well-being was associated with enhanced hemodynamic recovery following laboratory stressors but was not associated with stress reactivity.

Conclusions: Hedonic well-being, but not optimism, could potentially buffer against the effects of psychological stressors on physiological responding by relating to more complete recovery. Identifying the mechanisms contributing to these patterns of association may provide insights into psychological interventions for well-being and stress-related disease risk.
