To examine the effects of social support on cardiovascular reactions to behavioral stress, the present study tested the relative contribution of three elements of social support: the presence of another person in the laboratory; the presence of a person considered to be a friend; and physical touch. Sixty undergraduate females were assigned to one of the following groups: alone (A); friend present-touch (FT); friend present-no touch (FNT); stranger present-touch (ST); and stranger present-no touch (SNT). Heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) measures were obtained across baseline phases and during presentation of two behavioral challenges (mental arithmetic, mirror-tracing). The findings suggest that neither the presence of a stranger nor physical touch are related to attenuated cardiovascular reactions to stress; rather, if the extent of cardiovascular reactivity is related to social support, the presence of a friend may be the important mediating variable.
为了研究社会支持对行为应激时心血管反应的影响，本研究测试了社会支持三个要素的相对作用：实验室中有他人在场；有被视为朋友的人在场；身体接触。60名本科女生被分配到以下几组之一：单独组（A）；有朋友在场且有身体接触组（FT）；有朋友在场但无身体接触组（FNT）；有陌生人在场且有身体接触组（ST）；有陌生人在场但无身体接触组（SNT）。在基线阶段以及呈现两项行为挑战（心算、镜像追踪）期间获取心率（HR）、收缩压（SBP）和舒张压（DBP）测量值。研究结果表明，陌生人在场和身体接触均与应激时心血管反应减弱无关；相反，如果心血管反应程度与社会支持有关，那么有朋友在场可能是重要的中介变量。
