Fear of arousal symptoms, often referred to as anxiety sensitivity (AS), appears to be associated with risk for anxiety pathology and other Axis I conditions. However, AS is only one of three fundamental components of Reiss' Expectancy Model proposed to account for the development of anxiety problems. Very little research has focused on the other two components of this model (Fear of Negative Evaluation, Illness/Injury Sensitivity) and the specificity of AS, relative to these other two components, has rarely been evaluated. This study evaluated general and unique associations among all three so-called fundamental sensitivities to fearful responding to a biological challenge in a nonclinical sample (N=404). Participants were administered a 20-s inhalation of 20% CO2/balance O2. Consistent with hypothesis, only AS uniquely contributed to increased subjective fear responding to the challenge. These findings are consistent with Expectancy Theory in suggesting that the AS component of the model is specific to amplification of fears to arousal cues.
对唤醒症状的恐惧，通常被称为焦虑敏感性（AS），似乎与焦虑症及其他轴I障碍的风险有关。然而，AS只是赖斯期望模型中提出的用于解释焦虑问题发展的三个基本组成部分之一。很少有研究关注该模型的其他两个组成部分（对负面评价的恐惧、疾病/受伤敏感性），并且相对于其他两个组成部分，AS的特异性很少被评估。本研究在一个非临床样本（N = 404）中评估了对生物挑战产生恐惧反应的所有三种所谓基本敏感性之间的一般关联和独特关联。参与者接受了20%二氧化碳/其余为氧气的20秒吸入。与假设一致，只有AS独特地导致了对挑战的主观恐惧反应增加。这些发现与期望理论一致，表明该模型的AS成分特定于对唤醒线索的恐惧放大。
