While the benefits of social support for physiological health are well established, the underlying pathways by which support can influence cardiovascular reactivity (CVR) are still being elucidated. In the present study, we adapted an attachment framework to further explore the support-CVR link. Specifically, we experimentally tested the effect of attachment and social support on CVR by manipulating the provision of invisible support from a stranger, across individuals with secure, anxious and avoidant attachment styles. Employing a 3 × 2 design, a sample of young adults (N = 138) from across each of the three attachment styles were randomly assigned to either an invisible support (from a stranger), or no support, condition. All participants were subject to an acute standardised stress testing protocol where cardiovascular indices were monitored throughout. Results from a factorial ANOVA showed no significant interaction between support and attachment on any cardiovascular reactivity parameter (SBP, DBP, HR) or any main effect of attachment or support. These findings suggest that, in this case, social support was not effective in buffering the effects of stress across various attachment styles. The benefits of incorporating a developmental perspective to the study of social support and health are discussed.
虽然社会支持对生理健康的益处已得到充分证实，但支持影响心血管反应性（CVR）的潜在途径仍在阐明之中。在本研究中，我们采用了依恋框架来进一步探讨支持-CVR 之间的联系。具体来说，我们通过操纵来自陌生人的不可见支持的提供，在具有安全型、焦虑型和回避型依恋风格的个体中，实验性地测试了依恋和社会支持对 CVR 的影响。采用 3×2 设计，来自每个依恋风格的一组年轻成年人（N=138）被随机分配到不可见支持（来自陌生人）或无支持条件。所有参与者都接受了急性标准化应激测试方案，在此期间监测心血管指数。方差分析的结果表明，支持和依恋之间在任何心血管反应性参数（SBP、DBP、HR）上没有显著的交互作用，也没有依恋或支持的主要作用。这些发现表明，在这种情况下，社会支持并不能缓冲各种依恋风格下的压力的影响。讨论了将发展视角纳入社会支持和健康研究的好处。
