Anxiety sensitivity (AS) is an established transdiagnostic risk factor for emotional disorders. It is defined as the fear of anxiety sensations that arises from beliefs that those sensations can have harmful consequences on cognitive, physical, and social functioning. Thus, AS is usually considered a multidimensional construct comprised of the following dimensions: Cognitive, Physical, and Social concerns. Some studies have questioned its continuous latent structure providing taxometric evidence for its categorical nature. However, more advanced factor mixture modeling (FMM) has offered support for a hybrid, dimensional-categorial latent structure of AS. In other words, 3 qualitatively different classes were identified, with a 3-factor model within each class. In the current study, FMM was used in 2 independent Serbian samples: an adult convenient community (Facebook) sample (N = 359) and a young treatment-seeking sample (N = 342). The obtained results are fairly in line with the most recent work targeting the nature of the AS construct, using the Anxiety Sensitivity Index-3 (ASI-3). By model fit, especially comparing the 2- and 3-class solution in Sample 1, and testing external validity in Sample 2, the empirical evidence supports the 3-class solution, with classes labeled as Normative AS, Moderate AS, and High AS. Important theoretical and practical questions were raised and discussed in the article. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

焦虑敏感性的因子混合建模：支持塞尔维亚样本中的三类解决方案。

焦虑敏感性（AS）是情绪障碍的一种经诊断的危险因素。它被定义为对焦虑感的恐惧，这种恐惧是由于人们认为这些感觉会对认知，身体和社会功能产生有害影响而引起的。因此，AS通常被认为是由以下几个方面组成的多维构造：认知，身体和社会关注。一些研究质疑其连续的潜在结构为其分类性质提供了分类学证据。但是，更高级的因子混合模型（FMM）为AS的混合，按维分类的潜在结构提供了支持。换句话说，确定了3个在质量上不同的类别，每个类别中都有3因子模型。在当前的研究中，FMM用于两个独立的塞尔维亚样本中：一个成人便利社区（Facebook）样本（N = 359）和一个年轻的寻求治疗的样本（N = 342）。使用焦虑敏感性指数3（ASI-3），所得结果与针对AS结构性质的最新工作相当一致。通过模型拟合，尤其是比较样本1中的2类和3类解决方案，并在样本2中测试外部有效性，经验证据支持3类解决方案，其类别分别标记为标准AS，中度AS和高级AS。本文提出并讨论了重要的理论和实践问题。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。使用焦虑敏感指数3（ASI-3）。通过模型拟合，尤其是比较样本1中的2类和3类解决方案，并在样本2中测试外部有效性，经验证据支持3类解决方案，其类别分别标记为标准AS，中度AS和高级AS。本文提出并讨论了重要的理论和实践问题。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。使用焦虑敏感指数3（ASI-3）。通过模型拟合，尤其是比较样本1中的2类和3类解决方案，并在样本2中测试外部有效性，经验证据支持3类解决方案，其类别分别标记为标准AS，中度AS和高级AS。本文提出并讨论了重要的理论和实践问题。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
