The present investigation evaluated anxious and fearful responding to bodily sensations as a function of panic disorder (PD) and smoking status. Participants completed a voluntary hyperventilation procedure that elicits panic-relevant bodily sensations. Psychophysiological data were collected throughout the study procedures. Assessments of anxiety and bodily distress were conducted pre-challenge baseline, post-hyperventilation, and during a recovery period following the challenge. Results indicated that smokers with PD reported greater levels of anxiety and bodily distress than smokers without PD and than nonsmokers with PD at the post-challenge assessment and recovery period. No differences in autonomic responding were evident during the challenge or in the recovery phase. In terms of rate of recovery, the linear decrease in anxiety, but not bodily distress, was significantly more steep for nonsmokers with PD than for smokers with PD. These findings are discussed in relation to better understanding the potential role that smoking may play in terms of anxious and fearful responding to bodily sensations.
本研究评估了作为惊恐障碍（PD）和吸烟状况函数的对身体感觉的焦虑和恐惧反应。参与者完成了一项引发与惊恐相关身体感觉的自愿过度换气程序。在整个研究过程中收集了心理生理数据。在挑战前基线、过度换气后以及挑战后的恢复期进行了焦虑和身体不适的评估。结果表明，患有PD的吸烟者在挑战后评估和恢复期报告的焦虑和身体不适水平高于没有PD的吸烟者以及患有PD的非吸烟者。在挑战期间或恢复阶段，自主反应没有明显差异。就恢复速度而言，患有PD的非吸烟者焦虑的线性下降（而非身体不适）明显比患有PD的吸烟者更陡峭。结合更好地理解吸烟在对身体感觉的焦虑和恐惧反应方面可能发挥的潜在作用对这些发现进行了讨论。
