对不确定性的不容忍是指个体倾向于认为负面事件发生的可能性是不可接受的，无论发生的概率如何。它是担忧、状态焦虑和相关焦虑病理的关键组成部分。 27 项不确定性耐受量表 (IUS) 旨在衡量对不确定性的耐受性。先前对 IUS 的心理测量分析提出了四因素和五因素模型。项目间的高度相关性、因素不稳定性和先前的理论研究支持简化措施的开发。本研究使用了两个本科生样本，并评估了 IUS 的心理测量稳定的 12 项双因素版本。简化后的测量 (IUS-12) 保留了典型的内部一致性，同时与原始 JUS 以及相关的焦虑和担忧测量密切相关。 IUS-12 还表现出稳定的双因素结构，代表不容忍不确定性的焦虑和回避成分。讨论了未来研究的方向和评估的潜在应用。 (c) 2006 Elsevier Ltd 保留所有权利。
Intolerance of uncertainty is the tendency of an individual to consider the possibility of a negative event occurring unacceptable, irrespective of the probability of occurrence. It is a key component of worry, state anxiety, and related anxiety pathologies. The 27-item Intolerance of Uncertainty Scale (IUS) was developed to measure intolerance of uncertainty. Previous psychometric analyses of the IUS have suggested both four- and five-factor models. High inter-item correlations, factor instability, and previous theoretical research support the development of a reduced measure. The present study used two undergraduate samples and evaluated a psychometrically stable 12-item two-factor version of the IUS. The reduced measure (IUS-12) retained exemplary internal consistency, while correlating extremely well with the original JUS and related measures of anxiety and worry. The IUS-12 also demonstrated a stable two-factor structure, representing both anxious and avoidance components of intolerance of uncertainty. Directions for future research and potential applications for assessment are discussed. (c) 2006 Elsevier Ltd All rights reserved.
