The relationship between 23 specific panic attack symptoms and the 16 items of the Anxiety Sensitivity Index was investigated using a factor analytic procedure with a large sample (N = 209) of panic disorder patients. A five-factor model resulted in three panic symptom clusters (cardio-respiratory, dizziness-related, and cognitive symptoms) and two anxiety sensitivity factors (fear of physical symptoms and fear of psychological symptoms). The five-factor model accounted for 50% of the variance. There was some overlap between anxiety sensitivity and panic symptomatology and the cognitive panic symptom "fear of dying" loaded strongly on the anxiety sensitivity fear of physical sensations factor rather than on any of the panic symptoms factors. These results demonstrate that anxiety sensitivity can be independent of panic and are also consistent with a cognitive view of panic in which catastrophic cognitions that occur during a panic attack are more associated with a cognitive style or personality trait than with the severity of physical symptoms.
采用因子分析程序，对大量（N = 209）惊恐障碍患者样本，研究了23种特定惊恐发作症状与焦虑敏感性指数16项之间的关系。一个五因素模型产生了三个惊恐症状簇（心肺、头晕相关和认知症状）和两个焦虑敏感性因子（对身体症状的恐惧和对心理症状的恐惧）。五因素模型解释了50%的方差。焦虑敏感性和惊恐症状学之间存在一些重叠，认知惊恐症状“怕死”在焦虑敏感性对身体感觉的恐惧因子上负荷较强，而不是在任何惊恐症状因子上。这些结果表明，焦虑敏感性可以独立于惊恐，也与惊恐的认知观点一致，即惊恐发作期间出现的灾难性认知更多地与认知风格或人格特质相关，而不是与身体症状的严重程度相关。
