The present longitudinal study assessed the direction of effects between COVID-19 experiences, general well-being, socio-emotional motives for online communication, problematic social media use, and insomnia symptoms, among a sample of emerging adults at university. Participants (N = 619; 64% female; 66% White) completed an online survey 5 months apart during the COVID-19 pandemic. Results from an autoregressive cross-lagged model showed that poorer general well-being at baseline predicted greater endorsement of socio-emotional motives for online communication and higher insomnia symptoms over time. Negative COVID-19 experiences predicted higher social (but not emotional) motives for online communication. Lastly, insomnia symptoms and more problematic social media use predicted more negative COVID-19 experiences 5 months later (but not vice versa). Understanding the mechanisms of these associations will provide a better understanding of the factors that promote positive psychosocial functioning among emerging adults during the current COVID-19 pandemic and may inform psychosocial adjustment during future pandemics.

本纵向研究评估了大学新生样本中 COVID-19 经历、总体幸福感、在线交流的社会情感动机、有问题的社交媒体使用和失眠症状之间的影响方向。参与者 ( N= 619; 64% 女性；66% 的白人）在 COVID-19 大流行期间相隔 5 个月完成了一项在线调查。自回归交叉滞后模型的结果表明，基线时较差的总体幸福感预示着随着时间的推移，人们对在线交流的社会情感动机的认可度更高，失眠症状也会更高。负面的 COVID-19 经历预示着在线交流的更高社会（但不是情感）动机。最后，失眠症状和更多有问题的社交媒体使用预示着 5 个月后会有更多负面的 COVID-19 体验（但反之则不然）。了解这些关联的机制将有助于更好地了解在当前 COVID-19 大流行期间促进新兴成年人积极心理社会功能的因素，并可能为未来大流行期间的心理社会调整提供信息。
