Intolerance of uncertainty (IU) is considered to be associated with emotional disorders, such as generalized anxiety disorder (GAD), depression, obsessive compulsive disorder (OCD), and social anxiety. Therefore, a comprehensive instrument to measure IU is needed. The purposes of the present study were as follows: 1) developing a Chinese version of the Intolerance of Uncertainty Inventory (CIUI) and 2) measuring the reliability and validity of CIUI.
We translated the Intolerance of Uncertainty Inventory (IUI) into Chinese. A sample consisting of Chinese college students from three universities was used to evaluate the internal consistency, test-retest reliability, and validity of the CIUI. Participants answered the CIUI, IUS-12, GAD-7, BDI-II, and PSWQ. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were run to explore the factor structure of CIUI.
The results demonstrated an acceptable internal consistency for CIUI (Part A of CIUI [CIUIA]: α = 0.920; Part B of CIUI [CIUIB]: α = 0.947) and test-retest reliability (CIUIA: ICC = 0.788; CIUIB: ICC = 0.859). The results of EFA and CFA all supported a two-factor structure for CIUIA (Intolerance of the unexpected and difficulty waiting in an uncertain situation and Intolerance of uncertainty and of uncertain situations) and a four-factor structure for CIUIB (Overestimation, Control, Uncertainty makes one feel stressful, and Reassurance), and acceptable validity was obtained.
The CIUI is an appropriate instrument for measuring IU in Chinese populations. Future studies should confirm the psychometric properties using a comprehensive sample.
不确定性不耐受（IU）被认为与情绪障碍有关，如广泛性焦虑症（GAD）、抑郁症、强迫症（OCD）和社交焦虑症。因此，需要一种全面的工具来测量IU。本研究的目的如下：1）编制中文版不确定性不耐受量表（CIUI）；2）测量CIUI的信效度。
我们将不确定性不耐受量表（IUI）翻译成中文。使用来自三所大学的中国大学生样本评估CIUI的内部一致性、重测信度和效度。参与者回答了CIUI、IUS-12、GAD-7、BDI-II和PSWQ。进行探索性因素分析（EFA）和验证性因素分析（CFA）以探索CIUI的因素结构。
结果显示CIUI具有可接受的内部一致性（CIUI的A部分[CIUIA]：α = 0.920；CIUI的B部分[CIUIB]：α = 0.947）和重测信度（CIUIA：组内相关系数[ICC]=0.788；CIUIB：ICC = 0.859）。EFA和CFA的结果均支持CIUIA的两因素结构（对意外事件和在不确定情况下等待困难的不耐受以及对不确定性和不确定情况的不耐受）和CIUIB的四因素结构（高估、控制、不确定性使人感到压力和寻求安心），并获得了可接受的效度。
CIUI是测量中国人群中IU的合适工具。未来的研究应使用综合样本确认其心理测量特性。
