Intolerance of uncertainty (IU) has been implicated in the development and maintenance of worry and anxiety in adults and there is an increasing interest in the role that IU may play in anxiety and worry in children and adolescents.
We conducted a systematic review and meta-analysis to summarize existing research on IU with regard to anxiety and worry in young people, and to provide a context for considering future directions in this area of research. The systematic review yielded 31 studies that investigated the association of IU with either anxiety or worry in children and adolescents.
The meta-analysis showed that IU accounted for 36.00% of the variance in anxiety and 39.69% in worry. Due to the low number of studies and methodological factors, examination of potential moderators was limited; and of those we were able to examine, none were significant moderators of either association. Most studies relied on questionnaire measures of IU, anxiety, and worry; all studies except one were cross-sectional and the majority of the studies were with community samples.
The inclusion of eligible studies was limited to studies published in English that focus on typically developing children.
There is a strong association between IU and both anxiety and worry in young people therefore IU may be a relevant construct to target in treatment. To extend the existing literature, future research should incorporate longitudinal and experimental designs, and include samples of young people who have a range of anxiety disorders.
不确定性容忍度（IU）与成年人的担忧和焦虑的发展和维持有关，并且人们越来越关注 IU 在儿童和青少年的焦虑和担忧中可能扮演的角色。
我们进行了系统评价和荟萃分析，以总结 IU 与年轻人的焦虑和担忧相关的现有研究，并为该研究领域的未来方向提供背景。系统评价产生了 31 项研究，这些研究调查了 IU 与儿童和青少年的焦虑或担忧之间的关联。
荟萃分析表明，IU 解释了焦虑的 36.00%和担忧的 39.69%的方差。由于研究数量少和方法学因素，对潜在调节因素的检查受到限制；在我们能够检查的那些因素中，没有一个是这两个关联的显著调节因素。大多数研究依赖于 IU、焦虑和担忧的问卷测量；除了一项研究之外，所有研究都是横断面研究，而且大多数研究都是针对社区样本。
符合条件的研究仅限于以典型发展儿童为重点的英文发表的研究。
IU 与年轻人的焦虑和担忧之间存在很强的关联，因此 IU 可能是治疗中的一个相关结构。为了扩展现有文献，未来的研究应结合纵向和实验设计，并包括具有一系列焦虑障碍的年轻人样本。
