The influence of the availability of social support on cardiovascular reactivity to acute psychological stress was examined. Twenty-eight men and twenty-one women performed a speech task either in a support availability or no support availability condition while measures of systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were assessed. Consistent with past research, the speech stressor was associated with significant increases in SBP, DBP, and HR. More important, the availability of social support moderated cardiovascular reactivity to the acute stressor: individuals in the support availability condition were characterized by lower SBP and DBP reactivity to the acute stressor compared to individuals in the no support availability condition. These data suggest that simply having potential access to support is sufficient to foster adaptation to stress in the absence of enacted support.
研究了社会支持的可获得性对心血管系统对急性心理应激反应性的影响。28名男性和21名女性在有社会支持可获得或无社会支持可获得的条件下完成一项演讲任务，同时评估收缩压（SBP）、舒张压（DBP）和心率（HR）。与过去的研究一致，演讲应激源与SBP、DBP和HR的显著升高有关。更重要的是，社会支持的可获得性调节了心血管系统对急性应激源的反应性：与无社会支持可获得条件下的个体相比，有社会支持可获得条件下的个体对急性应激源的SBP和DBP反应性较低。这些数据表明，在没有实际支持的情况下，仅仅有获得支持的可能性就足以促进对压力的适应。
