Anxiety sensitivity, defined as the fear of anxiety and arousal-related sensations, has been among the most influential cognitive-based transdiagnostic risk and maintenance factors in the study and treatment of emotional and related disorders. The currently available anxiety sensitivity measures are limited by their length. Specifically, the length of these instruments discourages the adoption of routine anxiety sensitivity assessment in clinical or medical settings (e.g., primary care). The goals of this study were to develop and assess the validity and reliability of a short version of the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al., 2007), entitled the Short Scale Anxiety Sensitivity Index (SSASI), using three independent clinical samples. Results indicated that the abbreviated five-item version of the SSASI had good internal consistency and a robust association with the ASI-3. Further, across the samples, there was evidence of unidimensionality and excellent convergent and discriminant validity. There also was evidence of partial measurement invariance across sex and full measurement invariance across time. Overall, the five-item scale offers a single score that can be employed to measure anxiety sensitivity. Use of the SSASI may facilitate screening efforts and symptom tracking for anxiety sensitivity, particularly within clinical settings where practical demands necessitate the use of brief assessment instruments.
焦虑敏感是指对焦虑和与唤醒相关的感觉的恐惧，它是情感和相关障碍的研究和治疗中最有影响力的基于认知的跨诊断风险和维持因素之一。目前可用的焦虑敏感测量方法受到其长度的限制。具体来说，这些工具的长度阻碍了在临床或医疗环境中（例如，初级保健）常规进行焦虑敏感评估。本研究的目的是开发并评估焦虑敏感指数-3（ASI-3；Taylor 等人，2007）的简短版本，即短版焦虑敏感指数（SSASI）的有效性和可靠性，使用三个独立的临床样本。结果表明，SSASI 的简短五项目版本具有良好的内部一致性和与 ASI-3 的强大关联性。此外，在所有样本中，都有证据表明存在单一维度和极好的收敛和判别效度。在性别方面也存在部分测量不变性，在时间方面存在完全测量不变性。总体而言，五项量表提供了一个单一的分数，可以用于测量焦虑敏感性。SSASI 的使用可以促进焦虑敏感性的筛查工作和症状跟踪，特别是在需要使用简短评估工具的临床环境中。
