目的：已有文献表明，防御心理特征与交感神经应激反应的升高和一些心脏危险因素有关。这项研究的目的是检验这些先前关于防御的发现是否适用于哮喘人群。方法：采用marlow - crown社会期望量表，采用四分位数分割：高（上25%）和低（下75%）来测量防御性。22名防御性哮喘患者和66名非防御性哮喘患者接受实验室任务（初始基线休息时间、反应时间任务和商店事故影片）。结果：在任务期间，有证据表明防御性哮喘患者的皮肤电导水平较低，呼吸窦性心律失常幅度较大。暴露于任务后，防御性哮喘患者与非防御性哮喘患者相比，在肺活量测试中表现出下降。谁表现出了增长。结论：这些数据证实了个体反应刻板印象，并提示哮喘患者的防御可能以交感神经低觉醒和副交感神经高觉醒为特征。未来的研究需要确定防御是否是应激性支气管收缩的危险因素。
Objective: Previous literature has shown that the psychological trait of defensiveness is related to elevated sympathetic reactivity to stress and to several cardiac risk factors. The aim of this study was to examine whether these previous findings on defensiveness extend to an asthmatic population. Methods: Defensiveness was measured by the Marlowe-Crowne Social Desirability Scale using a quartile split: high (upper 25%) and low (bottom 75%). Twenty-two defensive and 66 nondefensive participants with asthma were exposed to laboratory tasks (initial baseline rest period, reaction time task, and a shop accident film). Results: During the tasks there was evidence of lower skin conductance levels and greater respiratory sinus arrhythmia amplitudes among defensive patients with asthma. After exposure to the tasks, defensive patients with asthma showed a decline on spirometry test measures compared with nondefensive asthmatic patients. who displayed an increase. Conclusions: These data confirm individual response stereotypy and suggest that defensiveness may be characterized by sympathetic hypoarousal and parasympathetic hyperarousal among patients with asthma. Future studies are needed to determine whether defensiveness is a risk factor for stress-induced bronchoconstriction.
