The tendency to perceive anxious states as aversive and harmful is hypothesized to confer vulnerability to the development of anxiety disorders. The most commonly used measure of anxiety sensitivity, the Anxiety Sensitivity Index [ASI; Reiss, S., Peterson, R.A., Gursky, D.M., & McNally R.J. (1986). Anxiety sensitivity, anxiety frequency, and the prediction of fearfulness. Behavior Research and Therapy, 24, 1-8], is composed of multiple lower-order factors, assessing fear of physical symptoms, fear of publicly observable anxious symptoms, and fear of cognitive dyscontrol. This study examined the convergent validity of the lower-order anxiety sensitivity dimensions in DSM-IV diagnosed anxiety disorders. Participants with primary diagnoses of panic disorder with agoraphobia, social phobia, and generalized anxiety disorder (GAD) completed the ASI and measures of anxiety and depression severity. Support was found for the convergent validity of all ASI dimensions in reference to thematically related anxiety disorders and in the identification of patients presenting with and without secondary major depressive disorder (MDD). The ASI-fear of cognitive dyscontrol dimension displayed strong and nonredundant associations with GAD, dimensional depression scores, and secondary diagnoses of MDD. The conceptual implications of the shared importance of fear of cognitive dyscontrol in GAD and MDD are discussed.
将焦虑状态视为厌恶和有害的倾向被假设为使人易患焦虑症。最常用的焦虑敏感性测量工具，即焦虑敏感性指数[ASI；赖斯，S.，彼得森，R.A.，古尔斯基，D.M.，&麦克纳利，R.J.（1986年）。焦虑敏感性、焦虑频率与恐惧预测。《行为研究与治疗》，24，1 - 8]，由多个低阶因素组成，评估对身体症状的恐惧、对公众可观察到的焦虑症状的恐惧以及对认知失控的恐惧。本研究考察了DSM - IV诊断的焦虑症中低阶焦虑敏感性维度的聚合效度。患有广场恐怖症的惊恐障碍、社交恐惧症和广泛性焦虑症（GAD）的主要诊断患者完成了ASI以及焦虑和抑郁严重程度的测量。在与主题相关的焦虑症方面以及在识别有无继发性重度抑郁症（MDD）的患者中，发现了所有ASI维度的聚合效度的支持证据。ASI - 对认知失控的恐惧维度与GAD、维度抑郁评分以及MDD的继发性诊断显示出强烈且非冗余的关联。讨论了在GAD和MDD中对认知失控的恐惧具有共同重要性的概念性影响。
