这项研究考察了社会支持是否可以降低心血管对急性应激源的反应性。大学生在三种社会条件中的一种情况下发表演讲：独自一人，在支持的邦联面前，或在不支持的邦联的面前。在休息时、演讲前和演讲中测量了收缩和舒张压。在预测和发表演讲时，受支持的和单独的受试者表现出的收缩压和舒张压的升幅明显小于不受支持的受试者。在演讲前和演讲期间，受支持的受试者的收缩压升幅也比单独受试者小得多。与女性相比，男性的压力相关血压增加更多；但性别并不能缓和社会支持对心血管反应性的影响。这些结果为在急性应激时社会支持的潜在健康益处提供了实验证据。
This study examined whether social support can reduce cardiovascular reactivity to an acute stressor. College students gave a speech in one of three social conditions: alone, in the presence of a supportive confederate, or in the presence of a nonsupportive confederate. Systolic and diastolic blood pressure were measured at rest, before the speech, and during the speech. While anticipating and delivering their speech, supported and alone subjects exhibited significantly smaller increases in systolic and diastolic blood pressures than did nonsupported subjects. Supported subjects also exhibited significantly smaller increases in systolic blood pressure than did alone subjects before and during the speech. Men had higher stress-related increases in blood pressures than did women; but gender did not moderate the effects of social support on cardiovascular reactivity. These results provide experimental evidence of potential health benefits of social support during acute stressors.
