Despite the prevalence of social media multitasking (SMM), its effects on well-being have received little attention. Of the nine studies that directly examined this topic, six found a negative relationship between SMM and well-being variables, and three found mixed or no effects. We compare the findings with those from five meta-analyses of general media multitasking (GMM) and 15 recent studies on GMM and well-being. We propose three pathways for the impact of SMM on well-being, with a potential mediating role of cognitive functions and performance. Based on the review, we suggest four directions for future research by emphasizing: (1) characteristics of SMM, (2) multiple goals of SMM, (3) different types and aspects of well-being (e.g., enjoyment, purpose), and (4) person-specific effects.

尽管社交媒体多任务（SMM）盛行，但其对幸福感的影响却很少受到关注。在直接检查该主题的九项研究中，六项发现 SMM 与幸福变量之间存在负相关关系，三项发现混合影响或没有影响。我们将这些发现与来自一般媒体多任务处理 (GMM) 的五项元分析和最近关于 GMM 和幸福感的 15 项研究的结果进行比较。我们提出了 SMM 对幸福感影响的三种途径，其中认知功能和表现具有潜在的中介作用。基于回顾，我们通过强调提出了未来研究的四个方向：（1）SMM的特征，（2）SMM的多重目标，（3）不同类型和方面的幸福感（例如，享受，目的），以及(4) 因人而异的效果。
