Increase in time spent on social media and its association with depressive symptoms, especially among young adults, has generated the need to understand how this association occurs in order to support the development of policies to reduce harm and complications. In view of this fact, this study aimed to assess the mediating effect of social media addiction and sleep quality on the association between time spent on social media and depressive symptoms in Brazilian university students. This is a cross-sectional study conducted with 2,823 university students, who provided information regarding time spent on social media, social media addiction, depressive symptoms and sleep quality. The mediation analysis, adjusted for confounding factors, was performed using the PROCESS macro for SPSS to obtain the total (c), direct (c'), and indirect effects (EI1, EI2, and EI3). The results identified an association between time spent on social media and depressive symptoms, mediated by social media addiction (EI1 = 20%) and sleep quality (EI1 = 40%). These findings help expand knowledge about the mechanisms that mutually influence the relationship between time spent on social media and depressive symptoms, supporting the adoption of strategies to reduce harm resulting from excessive social media use.
在社交媒体上花费的时间增加及其与抑郁症状的关联，尤其是在年轻人中，引发了人们对了解这种关联如何发生的需求，以便支持制定减少危害和并发症的政策。鉴于这一事实，本研究旨在评估社交媒体成瘾和睡眠质量在巴西大学生在社交媒体上花费的时间与抑郁症状之间的关联中所起的中介作用。这是一项对2823名大学生进行的横断面研究，这些学生提供了有关在社交媒体上花费的时间、社交媒体成瘾、抑郁症状和睡眠质量的信息。使用SPSS的PROCESS宏进行了针对混杂因素调整的中介分析，以获得总效应（c）、直接效应（c'）和间接效应（EI1、EI2和EI3）。结果确定了在社交媒体上花费的时间与抑郁症状之间存在关联，这种关联由社交媒体成瘾（EI1 = 20%）和睡眠质量（EI1 = 40%）介导。这些发现有助于扩展对相互影响在社交媒体上花费的时间与抑郁症状之间关系的机制的认识，支持采取策略减少过度使用社交媒体所带来的危害。
