A growing body of research has examined the potential effects of the Fear of Missing Out (FoMO) on Social Networking Site (SNS) use and Problematic SNS use (PSNSU). The aim of the current meta-analysis is to summarize findings on the relationship between FoMO levels and (i) SNS use and (ii) PSNSU. Furthermore, we meta-analyzed results on the associations between FoMO and some individual characteristics. The sample included 33 independent samples with a total of 21,473 participants. The results of the random-effects meta-analysis show a positive correlation between FoMO and SNS use and between FoMO and PSNSU, with effect sizes indicating robust associations. Age, sex, and geographic area of the samples did not moderate the associations. FoMO was positively correlated with depression, anxiety, and neuroticism and negatively correlated with consciousness. These results give robustness to the construct validity of FoMO itself, as this concept was introduced to explain why some people might be especially attracted to social media. Moreover, concerns that others might be having rewarding experiences that one is absent from seem to be a trigger for a compulsive use of social platforms, driven by the need to get in touch with others, or as tool to develop social competence.

越来越多的研究已经研究了对社交网站（SNS）使用和有问题的SNS使用（PSNSU）的恐惧缺失（FoMO）的潜在影响。当前荟萃分析的目的是总结关于FoMO水平与（i）SNS使用和（ii）PSNSU之间关系的发现。此外，我们对FoMO与某些个体特征之间的关联进行了荟萃分析。样本包括33个独立样本，共有21,473名参与者。随机效应荟萃分析的结果显示，FoMO和SNS使用之间以及FoMO和PSNSU之间存在正相关，且效应大小表明存在稳健的关联。样本的年龄，性别和地理区域并未缓解这种关联。FoMO与抑郁，焦虑，和神经质，与意识呈负相关。这些结果为FoMO本身的构造有效性提供了鲁棒性，因为引入此概念是为了解释为什么某些人可能会特别被社交媒体所吸引。此外，担心他人可能会获得有益的经验，而这种经验似乎是由于需要与他人保持联系而被迫强迫使用社交平台的触发因素，或者是发展社交能力的工具。
