It has been previously shown that the implicit affiliation motive - the need to establish and maintain friendly relationships with others - leads to chronic health benefits. The underlying assumption for the present research was that the implicit affiliation motive also moderates the salivary cortisol response to acute psychological stress when some aspects of social evaluation and uncontrollability are involved. By contrast we did not expect similar effects in response to exercise as a physical stressor. Fifty-nine high school students aged M=14.8 years were randomly assigned to a psychosocial stress (publishing the results of an intelligence test performed), a physical stress (exercise intensity of 65-75% of HRmax), and a control condition (normal school lesson) each lasting 15min. Participants' affiliation motives were assessed using the Operant Motive Test and salivary cortisol samples were taken pre and post stressor. We found that the strength of the affiliation motive negatively predicted cortisol reactions to acute psychosocial but not to physical stress when compared to a control group. The results suggest that the affiliation motive buffers the effect of acute psychosocial stress on the HPA axis.
先前的研究表明，内隐亲和动机——即与他人建立和维持友好关系的需求——会给健康带来长期益处。本研究的基本假设是，当涉及社会评价和不可控性的某些方面时，内隐亲和动机也会调节唾液皮质醇对急性心理应激的反应。相比之下，我们预计对作为身体应激源的运动不会有类似的反应。59名平均年龄为14.8岁的高中生被随机分配到心理社会应激组（公布所进行的智力测试结果）、身体应激组（运动强度为心率最大值的65%-75%）和对照组（正常学校课程），每组持续15分钟。使用操作性动机测试评估参与者的亲和动机，并在应激源前后采集唾液皮质醇样本。我们发现，与对照组相比，亲和动机的强度对急性心理社会应激而非身体应激的皮质醇反应具有负向预测作用。结果表明，亲和动机缓冲了急性心理社会应激对下丘脑-垂体-肾上腺轴的影响。
