焦虑敏感性（AS）是指基于对焦虑相关感觉有害后果的信念而产生的对这些感觉的恐惧。尽管焦虑敏感性指数是最常用的焦虑敏感性测量工具，但它过于简略，无法充分测量该构念的躯体、认知和社会方面。《焦虑敏感性指数修订版》（ASI - R）是焦虑敏感性指数的修订和扩展版本，其开发目的是改进对焦虑敏感性及其维度的评估。本研究旨在检验ASI - R的心理测量学特性和因素结构。两个大型本科生样本完成了一个心理测量评估包，其中包括ASI - R以及焦虑、抑郁和相关构念的测量工具。探索性因素分析揭示了四个ASI - R低阶因素：（1）对躯体感觉有害后果的信念；（2）对公开可见的焦虑反应的恐惧；（3）对认知失控的恐惧；（4）对无明确后果的躯体感觉的恐惧。这些因素负载于一个单一的高阶因素上。ASI - R各因素与相关变量之间的相关性符合焦虑敏感性理论。本研究中两个样本的结果高度相似。讨论了ASI - R的优势和局限性，并考虑了我们的研究结果对焦虑敏感性的性质和测量的影响。（C）2003爱思唯尔有限公司。保留所有权利。
Anxiety sensitivity (AS) is the fear of anxiety-related sensations based on beliefs about their harmful consequences. Despite its status as the most popular measure of AS, the anxiety sensitivity index is too abbreviated to adequately measure the somatic, cognitive, and social facets of the construct. The Anxiety Sensitivity Index - Revised (ASI-R) is a revised and expanded version of the ASI that was developed to improve the assessment of AS and its dimensions. The present study was conducted to examine the psychometric properties and factor structure of the ASI-R. Two large undergraduate samples completed a psychometric assessment package that included the ASI-R and measures of anxiety, depression, and related constructs. Exploratory factor analysis revealed four lower-order ASI-R factors: (1) beliefs about the harmful consequences of somatic sensations; (2) fear of publicly observable anxiety reactions; (3) fear of cognitive dyscontrol, and (4) fear of somatic sensations without explicit consequences. These factors loaded on a single, higher-order factor. Correlations between the ASI-R factors and related variables were consistent with AS theory. Results across both samples in the present study were highly similar. The strengths and limitations of the ASI-R are discussed, and the implications of our findings for the nature and measurement of AS are considered. (C) 2003 Elsevier Ltd. All rights reserved.
