Anxiety sensitivity (AS), the fear of sensations of anxious arousal based on beliefs about their harmful consequences, is increasingly recognized as a multidimensional construct. The recently developed Anxiety Sensitivity Index-3 [ASI-3; Taylor, S., Zvolensky, M., Cox, B., Deacon, B., Heimberg, R., Ledley, D. R., et al. (2007). Robust dimensions of anxiety sensitivity: Development and initial validation of the Anxiety Sensitivity Index-3 (ASI-3). Psychological Assessment, 19, 176-188] measures three dimensions of AS: physical concerns, social concerns, and cognitive concerns. The ASI-3 shows promise, although further evaluation of its psychometric properties and validity in independent samples is needed. We evaluated the ASI-3 in a mixed sample of anxiety disorder patients (N=506) and undergraduate student controls (N=315). The measure demonstrated a stable 3-factor structure and sound psychometric properties, with the three factors showing theoretically consistent patterns of associations with anxiety symptoms and diagnoses. ASI-3 total scores were less discriminative. Implications for conceptual models of anxiety are discussed.
焦虑敏感（AS）是指基于对焦虑唤醒的有害后果的信念而对感觉产生恐惧，它越来越被认为是一个多维结构。最近开发的焦虑敏感指数-3（ASI-3；Taylor，S.，Zvolensky，M.，Cox，B.，Deacon，B.，Heimberg，R.，Ledley，D. R.，等人，2007 年）测量了 AS 的三个维度：身体关注、社会关注和认知关注。ASI-3 显示出了一定的前景，尽管还需要对其在独立样本中的心理测量特性和有效性进行进一步评估。我们在混合的焦虑障碍患者样本（N=506）和大学生对照组（N=315）中评估了 ASI-3。该测量方法表现出稳定的 3 因素结构和良好的心理测量特性，这三个因素与焦虑症状和诊断呈现出理论上一致的关联模式。ASI-3 的总分区分度较低。讨论了对焦虑概念模型的影响。
