| Summary: | 碩士 === 國立臺灣大學 === 心理學研究所 === 92 === Clark’s cognitive model (1986) proposed that the trigger for panic attacks could also be the perception of bodily sensations caused by innocuous events such as exercise. However, laboratory investigations which measured either anxiety symptoms or sought to assess exercise-induced panic attacks were almost irrelevant of testing Clark’s model. Many of them employed high intensity exercise to see whether such a stimulus would provoke a panic attack. Some even have drawbacks of experimental designs. The present study followed an interactional approach postulated by Cox (1996), a ‘person-by-situation’ perspective, to examine Clark’s proposition. The effects of anxiety sensitivity, cognitive manipulation on subjective and cardiac responses during the course of exercise were examined. Specifically, 64 nonclinical subjects selected from anxiety sensitivity index finished panic attack questionnaire, then were randomly assigned to one of two different cognitive manipulations. They underwent a graded exercise test and finished a checklist of cognitions and bodily sensations. Heart rate was measured simultaneously. An anxiety sensitivity × cognitive manipulation or anxiety sensitivity × cognitive manipulation × stages factorial design were performed. Results showed that under equivalent bodily activation levels, cognitive factors did play a significant role in the development of panic attacks. Meanwhile, the interactional approach could be verified. It was claimed that the present study could add the understanding of the psychopathology of panic patients and make some contribution to how to use exercise task in clinical settings.
