Abstract Fear of missing out (FoMO) describes the concern of missing out on a rewarding experience. Though research demonstrates anxiety and depression severity are related to FoMO, there are gaps in the literature regarding mediating factors between these variables which may explain why not everyone is equally inclined to experience FoMO. Specifically, boredom proneness and anxiety attachment may provide further understanding of how FoMO intensity is not uniform for individuals of similar anxiety and depression severity. The aims of this study were to test if boredom proneness mediates the relations of both anxiety and depression severity with FoMO. An additional aim was to examine if anxiety attachment mediates the relationship between boredom proneness and FoMO. To this end, we recruited 450 adults from across the United States who completed multiple survey measures. By use of Structural Equation Modeling (SEM) we tested multiple theoretical models. Results indicated anxiety attachment influences how boredom proneness predicts FoMO. Additionally, boredom proneness appears to regulate the activation of anxiety attachment by mediating anxiety and depression severity. Boredom proneness also mediated the relations of anxiety and depression severity with FoMO. As not everyone is equally inclined to FoMO, the current research contributes to the empirical literature by highlighting individual differences which further explain the apprehensions that one is missing out. We discuss the multi-dimensional nature of FoMO and the theoretical basis for our results. Limitations and suggestions for future research is outlined.

焦虑、无聊和（可能）错过：对焦虑依恋、无聊倾向和错过的恐惧 (FoMO) 的评估

摘要害怕错过 (FoMO) 描述了对错过有益体验的担忧。尽管研究表明焦虑和抑郁的严重程度与 FoMO 相关，但关于这些变量之间的中介因素的文献中存在空白，这可能解释了为什么不是每个人都同样倾向于体验 FoMO。具体而言，无聊倾向和焦虑依恋可以进一步了解具有相似焦虑和抑郁严重程度的个体的 FoMO 强度如何不一致。本研究的目的是测试无聊倾向是否介导了焦虑和抑郁严重程度与 FoMO 之间的关系。另一个目的是检查焦虑依恋是否介导了无聊倾向和 FoMO 之间的关系。为此，我们从美国各地招募了 450 名完成多项调查措施的成年人。通过使用结构方程建模 (SEM)，我们测试了多个理论模型。结果表明，焦虑依恋会影响无聊倾向如何预测 FoMO。此外，无聊倾向似乎通过调节焦虑和抑郁的严重程度来调节焦虑依恋的激活。无聊倾向也调节了焦虑和抑郁严重程度与 FoMO 的关系。由于并非每个人都同样倾向于 FoMO，因此当前的研究通过强调个体差异来为实证文献做出贡献，这进一步解释了人们对错过的担忧。我们讨论了 FoMO 的多维性质以及我们结果的理论基础。概述了未来研究的局限性和建议。
