Effects of life stress on psychobiological responsivity and health behaviors

健康心理学越来越多地涉及三个基本问题：第一，谁会生病，为什么？第二，与其他已知的影响疾病的因素相比，压力有多重要？第三，压力如何导致NI健康？什么是机制或过程联系的经验，压力与身体的物理变化。本研究采用压力与健康的实验-现场研究方法，从700名大学生中筛选出30名大学生，根据压力问卷的得分进行追踪调查。在1.5年的追踪期间，高压力组的病患比低压力组的病患有更多的疾病，例如传染病。除此之外，高压力的学生显着更大的心理生物学压力反应在每一个超过1.5年的随访期间的四个精神压力测试。虽然这将是非常错误的结论，对于某些人来说，疾病的发病纯粹是由压力因素引起的，这项研究清楚地表明，有真实的作用的压力，导致健康状况不佳，甚至身体疾病。

Health psychology has increasingly embraced three essential questions : First, who becomes sick and why? Second, how important is stress, in comparison with other factros that are known to affect illness? Third, how does stress lead to Nl-health? What are the mechanisms or processes linking the experience of stress with physical changes in the body. This study is to investigate these questions by the method of experimental-field study of stress and health.We followed 30 universitudents men wo had been screened from the general population of 700 students according to the scores of stress questionnaire. Subjects classfied as high stress group reported more instances of illness such as infectious disease during follow-up period of 1.5 years than subjects classfied as low stress group did. In addition to this, high stress students significantly greater psychobiological stress responsivity at each of four mental stress testing over 1.5 years follow-up period.Although it would be quite wrong to conclude that for certain individuals, the onset of illness is caused purely by stress factors, this study clearly demonstrated the evidence that there is real role of stress in leading to poor health and even physical illness.
