Review Meta AnalysisInvestigating the influence of social support on experimental pain and related physiological arousal: A systematic review and meta-analysis.
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. ⋯ 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.
