Problematic social media use and sleep disturbances are independently related with mental health. However, evidence of combined effects of changes in problematic social media use and sleep disturbances on changes in depressive symptoms in adolescents is limited. The aim of this study was to examine complex longitudinal associations between problematic social media use, sleep disturbances and depressive symptoms during middle adolescence.
A 2-year longitudinal study was conducted consisting of three waves, each separated by 1 year. The participants were 249 Estonian adolescents (46,6% female) aged 15.3 ± 0.3 years (M ± SD) who completed self-report measures of problematic social media use, sleep disturbances and depressive symptoms.
The findings revealed that initial level in both problematic social media use and sleep disturbances both significantly predicted change in depressive symptoms. Moreover, the increases in problematic social media use and sleep disturbances were both associated with an increase in depressive symptoms, irrespective of gender.
Our findings add strength to the evidence supporting longitudinal associations between problematic social media use and depressive symptoms and sleep disturbances and depressive symptoms in middle adolescence.
社交媒体使用问题和睡眠障碍均与心理健康独立相关。然而，关于社交媒体使用问题和睡眠障碍变化对青少年抑郁症状变化的综合影响的证据有限。本研究旨在探讨青少年中期社交媒体使用问题、睡眠障碍和抑郁症状之间复杂的纵向关联。
本研究进行了一项为期 2 年的纵向研究，共包括 3 个时间点，每个时间点间隔 1 年。参与者为 249 名爱沙尼亚青少年（46.6%为女性），年龄为 15.3±0.3 岁（M±SD），他们完成了社交媒体使用问题、睡眠障碍和抑郁症状的自我报告测量。
研究结果表明，社交媒体使用问题和睡眠障碍的初始水平均显著预测抑郁症状的变化。此外，无论性别如何，社交媒体使用问题和睡眠障碍的增加均与抑郁症状的增加相关。
本研究结果为青少年中期社交媒体使用问题与抑郁症状以及睡眠障碍与抑郁症状之间的纵向关联提供了有力证据。
