Taxometric相干切割动力学分析被用来测试焦虑敏感性的潜在结构在样本来自北美（加拿大和美国），法国，墨西哥，西班牙和荷兰（总n = 2741）。焦虑敏感性由36项焦虑敏感性指数修订版（ASI-R; J. Anxiety Disord. 12（5）（1998）463]）。使用ASI-R构建了四个明显的焦虑敏感性指标：对心血管症状的恐惧，对呼吸道症状的恐惧，对公众可观察到的焦虑反应的恐惧，以及对精神丧失能力的恐惧。MAXCOV-HITMAX、内部一致性检验、4个模拟Monte Carlo数据分析和MAMBAC外部一致性检验的结果表明，焦虑敏感性的潜在结构在每个样本中都是分类的。焦虑敏感性分类的估计基础率在国家之间略有不同，范围从11.5%到21.5%。总的来说，四个基于ASI-R的显性指标显示出高水平的有效性。结果进行了讨论，在有关的概念理解焦虑敏感性，具体强调理论完善的建设。(c)2004年爱思唯尔公司All rights reserved.
Taxometric coherent cut kinetic analyses were used to test the latent structure of anxiety sensitivity in samples from North America (Canada and United States of America), France, Mexico, Spain, and The Netherlands (total n = 2741). Anxiety sensitivity was indexed by the 36-item Anxiety Sensitivity Index-Revised (ASI-R; [J. Anxiety Disord. 12(5) (1998) 463]). Four manifest indicators of anxiety sensitivity were constructed using the ASI-R: fear of cardiovascular symptoms, fear of respiratory symptoms, fear of publicly observable anxiety reactions, and fear of mental incapacitation. Results from MAXCOV-HITMAX, internal consistency tests, analyses 4 simulated Monte Carlo data, and a MAMBAC external consistency test indicated that the latent structure of anxiety sensitivity was taxonic in each of the samples. The estimated base rate of the anxiety sensitivity taxon differed slightly between nations, ranging from 11.5 to 21.5%. In general, the four ASI-R, based manifest indicators showed high levels of validity. Results are discussed in relation to the conceptual understanding of anxiety sensitivity, with specific emphasis on theoretical refinement of the construct. (c) 2004 Elsevier Inc. All rights reserved.
