Social support is demonstrated to have mixed effects on both pain and related physiological arousal. In this study, a meta-analysis was conducted to characterise these effects. A total of 2416 studies were identified in a systematic search, among which 21 were eligible for the quantitative review. The mere presence of another person was not sufficient to modulate pain perception. However, the presence of a stranger was identified to decrease pain-related arousal (SMD = -0.31), and the presence of a significant other increased facial expression of pain (SMD = 0.21). We further found verbal support to decrease pain (SMD = -0.69) and arousal (SMD = -0.99), and we demonstrated moderate to large analgesic effects of intimate relationships through touching (SMD = -0.95) and viewing (SMD = -0.60) of a romantic partner. Finally, we presented evidence of publication bias for pain-related arousal but not for behavioural pain outcomes. Together, our findings suggest that the impact of social support on pain is context-dependent with the verbal communication of support and intimate relationships being of particular importance.
社会支持对疼痛及其相关生理唤醒既有积极影响，也有消极影响。本研究采用荟萃分析方法对这些影响进行了研究。系统检索共确定了 2416 项研究，其中有 21 项符合定量综述的纳入标准。仅仅有他人在场并不足以调节疼痛感知。然而，有陌生人在场被发现可以降低与疼痛相关的唤醒（SMD=-0.31），而有重要他人在场则会增加疼痛的面部表情（SMD=0.21）。我们还发现言语支持可以降低疼痛（SMD=-0.69）和唤醒（SMD=-0.99），通过触摸（SMD=-0.95）和观看（SMD=-0.60）伴侣，我们还证明了亲密关系具有中度到高度的镇痛作用。最后，我们对与疼痛相关的唤醒存在发表偏倚的证据，但对行为疼痛结果则没有。总之，我们的研究结果表明，社会支持对疼痛的影响具有情境依赖性，其中支持的言语交流和亲密关系尤为重要。
