Extant research suggests that digital stress (DS) and its various components (Hall et al. in Psychol Assess 33(3):230–242, 2021) may mediate the association between social media use and psychosocial distress among adolescents and young adults. Yet no systematic review and meta-analysis has been conducted to examine the direct associations among DS components (i.e., approval anxiety, availability stress, fear of missing out [FOMO], connection overload, and online vigilance) and psychological outcomes. Thus, we aimed to comprehensively synthesize and quantify the association between these five DS components and psychosocial distress, and to examine whether these associations were statistically different from one another. Our search of PubMed, PsycINFO, and Communication and Mass Media Complete yielded a wide range of article abstracts across the five DS components. After reviewing inclusion and exclusion criteria, 7, 73, 60, 19, and 16 studies were included for availability stress, approval anxiety, FOMO, connection overload, and online vigilance, respectively. The results suggested that all five digital stress components had significant medium association with psychosocial distress (r = .26 to .34; p < .001). Age and sex did not significantly moderate the association between most digital stress components and psychosocial distress. However, age moderated the association between connection overload and psychosocial distress. Our findings further suggested no statistical differences among the associations between the five digital stress components and psychosocial distress. Notwithstanding its limitations, our outcomes help integrate the disparate effect sizes in the literature, indicate the strength of associations, and suggest directions for clinical intervention and future research.

现有研究表明，数字压力 (DS) 及其各种组成部分（Hall 等人，Psychol Assess 33(3):230–242, 2021）可能会介导青少年和年轻人中社交媒体使用与社会心理困扰之间的关联。然而，还没有进行系统回顾和荟萃分析来检验 DS 组成部分（即批准焦虑、可用性压力、害怕错过 [FOMO]、连接过载和在线警惕性）和心理结果之间的直接关联。因此，我们的目的是全面综合和量化这五种 DS 成分与社会心理困扰之间的关联，并检验这些关联是否彼此之间存在统计学差异。我们对 PubMed、PsycINFO 以及 Communication and Mass Media Complete 的搜索产生了涵盖五个 DS 组成部分的广泛文章摘要。在审查纳入和排除标准后，分别纳入了 7、73、60、19 和 16 项针对可用性压力、批准焦虑、FOMO、连接过载和在线警惕性的研究。结果表明，所有五个数字压力成分均与社会心理困扰具有显着的中等关联（r  = .26 至 .34；p  < .001）。年龄和性别并没有显着调节大多数数字压力成分与社会心理困扰之间的关联。然而，年龄调节了连接超负荷与社会心理困扰之间的关联。我们的研究结果进一步表明，五种数字压力成分与社会心理困扰之间的关联不存在统计差异。尽管存在局限性，但我们的结果有助于整合文献中不同的效应大小，表明关联的强度，并为临床干预和未来研究提出方向。
