Test anxiety is common among university students and more effective interventions are needed. The Intolerance of Uncertainty (IU) model underpins an effective intervention for anxiety. IU is the propensity to react negatively to uncertainty. The Intolerance of Uncertainty Scale – 12 (IUS-12) is the most common scale for measuring IU. This study examined for the first time the factor structure of the IUS-12 in UK samples, and explored the relationship between IU and trait and state test anxiety. Factor analyses supported a bifactor model with a robust and reliable general IU factor, which was replicated across two samples. IU was strongly associated with both trait and state test anxiety.

考试焦虑在大学生中很普遍，需要更有效的干预措施。不确定性的不容忍（IU）模型为焦虑症的有效干预奠定了基础。IU是对不确定性做出负面反应的倾向。不确定度量表– 12（IUS-12）是测量IU的最常见量表。这项研究首次检查了英国样本中IUS-12的因子结构，并探讨了IU与性状和状态测试焦虑之间的关系。因子分析支持具有可靠且可靠的一般IU因子的双因子模型，该模型可在两个样本中复制。IU与特质和状态测试焦虑密切相关。
