本研究首次在东亚（韩国）样本中检验了焦虑敏感指数 - 3（ASI - 3）潜在的双因子结构的适用性，并确定双因子模型中的哪些因子与焦虑、抑郁和负面情绪显著相关。我们以289名韩国大学生为样本，比较了（a）原始的三因子焦虑敏感（AS）模型，（b）三组双因子AS模型，以及（c）两组双因子AS模型（仅存在身体和社交担忧组因子）。结果显示，两组双因子AS模型对ASI - 3数据的拟合度最佳。相关地，尽管所有ASI - 3项目都在一般焦虑敏感因子上有负荷，但认知担忧组因子在双因子模型中未被定义，因此在跨文化背景下进行因子分析和结构方程模型（SEM）时，为了准确地对焦虑敏感进行建模，可能需要将其省略。SEM结果还显示，一般焦虑敏感因子是两组双因子模型中唯一能显著预测焦虑、抑郁和负面情绪的因子。本文讨论了这种新的焦虑敏感双因子结构在东亚样本中的意义和重要性。（C）2016爱思唯尔有限公司。保留所有权利。
The present study was the first to examine the applicability of the bifactor structure underlying the Anxiety Sensitivity Index-3 (ASI-3) in an East Asian (South Korean) sample and to determine which factors in the bifactor model were significantly associated with anxiety, depression, and negative affect. Using a sample of 289 South Korean university students, we compared (a) the original 3-factor AS model, (b) a 3-group bifactor AS model, and (c) a 2-group bifactor AS model (with only the physical and social concern group factors present). Results revealed that the 2-group bifactor AS model fit the ASI-3 data the best. Relatedly, although all ASI-3 items loaded on the general AS factor, the Cognitive Concern group factor was not defined in the bifactor model and may therefore need to be omitted in order to accurately model AS when conducting factor analysis and structural equation modeling (SEM) in cross cultural contexts. SEM results also revealed that the general AS factor was the only factor from the 2-group bifactor model that significantly predicted anxiety, depression, and negative affect. Implications and importance of this new bifactor structure of Anxiety Sensitivity in East Asian samples are discussed. (C) 2016 Elsevier B.V. All rights reserved.
