本研究旨在探讨忧虑在不确定性不耐受（IU）与抑郁和焦虑症状之间的间接和调节作用。这项研究是一项横断面研究。数据收集自120名22至37岁的精神病患者。研究人员对IU、担忧、抑郁和焦虑症状进行了一系列自我报告问卷调查。间接效应分析的结果显示，尽管IU、担忧、抑郁和焦虑症状之间存在中度相关性，但担忧在预测抑郁和焦虑症状方面存在很大比例的差异。然而，与抑郁症状相比，焦虑症状的相对效果更为明显。层次分析结果支持焦虑的调节作用。更具体地说，高水平的担忧增强了IU与抑郁和焦虑症状之间的联系。考虑到担忧可能是一种机制，和/或IU与抑郁和焦虑症状之间的调节因素，倾向于使用这种消极重复思维过程（例如担忧）的成年人可能有更高的风险出现心理症状。
The present study sought to examine the indirect and moderating effects of worry between intolerance of uncertainty (IU) and symptoms of depression and anxiety. The study was a cross sectional study. Data were collected from 120 psychiatric patients, aged 22 to 37 years. A battery of self-report questionnaires was administered for tapping IU, worry, depression and anxiety symptoms. Results from indirect effects analyses revealed that even though IU, worry, depression, and anxiety symptoms correlated moderately with each other, worry carried a substantial proportion of variance in predicting symptoms of depression and anxiety. However, the relative effect was more pronounced for anxiety compared to depression symptoms. The results from hierarchical analyses supported the moderator role of worry. More specifically, a high level of worry enhanced the association between IU and symptoms of depression and anxiety. Given the potential for worry as a mechanism, and/or moderator between IU and symptoms of depression and anxiety, adults with a tendency to use this negative repetitive thought process (e.g. worry) may be at higher risk to develop psychological symptoms.
