A reliable finding from the physical pain literature is that individuals with higher resting (i.e., tonic) blood pressure experience relatively less pain in response to nociceptive stimuli. Converging lines of evidence suggest that biological factors that influence the experience of physical pain may also relate to social pain. An open question, however, is whether higher blood pressure per se is a biological factor associated with lower sensitivity to social pain. This possible association was tested in three studies. Consistent with prior findings on physical pain, higher resting blood pressure was associated with lower self-reported sensitivity to social pain across individuals (Study 1 r = -.303, Study 2 r = -.262, -.246), even after adjusting for confounding factors related to blood pressure (Study 3 r = -.222). Findings suggest a previously unknown biological correlate of sensitivity to social pain, providing further evidence for possible shared substrates for physical and social pain.
疼痛文献中的一个可靠发现是，静息（即紧张性）血压较高的个体对伤害性刺激的疼痛反应相对较小。越来越多的证据表明，影响身体疼痛体验的生物学因素可能也与社会疼痛有关。然而，一个悬而未决的问题是，较高的血压本身是否是与对社会疼痛较低敏感性相关的生物学因素。在三项研究中对这种可能的关联进行了测试。与先前关于身体疼痛的研究结果一致，即使在调整了与血压相关的混杂因素后，静息血压较高与个体对社会疼痛的自我报告敏感性较低相关（研究1 r = -0.303，研究2 r = -0.262，-0.246；研究3 r = -0.222）。研究结果表明存在一种先前未知的与社会疼痛敏感性相关的生物学关联，为身体疼痛和社会疼痛可能存在共同的基质提供了进一步的证据。
