Previous research has indicated that gratitude and affect-balance play key stress-buffering roles. However, to date there is limited research on the impact of gratitude and affect balance on cardiovascular recovery from acute psychological stress, and whether affect balance moderates the relationship between gratitude and cardiovascular reactions to acute psychological stress. In this study, 68 adults completed measures of state gratitude, positive and negative affect, and completed a laboratory-based cardiovascular stress-testing protocol. This incorporated a 20-minute acclimatization period, a 10-minute baseline, a 6-minute arithmetic stress task, and an 8-minute recovery period. Mixed-effects growth curve models were fit and the results indicated that state gratitude predicted lower systolic blood pressure responses throughout the stress-testing period. Affect balance was found to moderate the association between state gratitude and diastolic blood pressure responses to stress, amplifying the effects of state gratitude. These findings suggest that state gratitude has a unique stress-buffering effect on both reactions to and recovery from acute psychological stress.
先前的研究表明，感恩和情感平衡起着关键的压力缓冲作用。然而，迄今为止，关于感恩和情感平衡对急性心理应激后心血管恢复的影响，以及情感平衡是否调节感恩与急性心理应激的心血管反应之间的关系，相关研究还很有限。在本研究中，68名成年人完成了状态感恩、积极和消极情感的测量，并完成了一项基于实验室的心血管压力测试方案。该方案包括一个20分钟的适应期、一个10分钟的基线期、一个6分钟的算术压力任务和一个8分钟的恢复期。拟合了混合效应生长曲线模型，结果表明，状态感恩预测了整个压力测试期间较低的收缩压反应。研究发现，情感平衡调节了状态感恩与应激舒张压反应之间的关联，增强了状态感恩的影响。这些发现表明，状态感恩对急性心理应激的反应和恢复都具有独特的压力缓冲作用。
