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.

幸福与压力生理相关吗？系统的审查和荟萃分析。

目的目前的荟萃分析测试了健康成年人的性格特征指标是否与压力诱发的生理反应性和恢复有关。方法使用Medline，PsycINFO和PubMed来识别相关文章。包括以下内容的文章：（a）在急性实验室应激范例期间或之后测量了心血管或神经内分泌（但未免疫）的生理学；（b）测量了享乐，中性或乐观的指标，并且（c）健康的成人参与者。实验室压力任务包括令人沮丧的认知任务，情绪回忆任务以及涉及社会评估的任务。生理变量汇总于心脏（心率和心输出量），血液动力学（平均动脉压，收缩压和舒张压），HPA（皮质醇），和自主性（高频心率变异性，皮肤电导和儿茶酚胺）标记。纳入了27项研究（n = 3,390； 54.6％的女性）。使用具有合并方差的随机效应模型估计效应大小和置信区间。结果与预期相反，乐观与认知应激源的心脏反应性增强有关，但与压力恢复无关。相比之下，享乐幸福感与实验室应激源后血液动力学恢复增强有关，但与应激反应性无关。结论享乐，但不是乐观，通过与更完全的恢复有关，可以潜在地缓解心理压力对生理反应的影响。识别促成这些关联模式的机制可能会提供有关心理干预的知识，这些心理干预可促进幸福感和与压力相关的疾病风险。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
