The association between excessive screen media use and mental health problems has attracted widespread attention. The literature to date has neglected the biological mechanisms underlying such a relationship and failed to distinguish between different types of screen media activities. A sample from the Adolescent Brain and Cognitive Development study was used in the present study to elucidate the longitudinal associations between specific types of screen media use, brain development, and diverse mental health problems. The results showed that different types of screen media use have differentiated associations with mental health problems, subcortical volume, and cortical-subcortical connectivity. Specifically, more passive media use was associated with increased rule-breaking behavior, while more video game playing was associated with increased withdrawn/depressed symptoms. In addition, more social media use was associated with a reduced volume of the hippocampus, caudate, and thalamus proper. More research is needed to examine the differential effects of screen media use on neurodevelopmental processes and mental health problems across adolescence.
过度使用屏幕媒体与心理健康问题之间的关联已引起广泛关注。迄今为止的文献忽略了这种关系背后的生物学机制，并且未能区分不同类型的屏幕媒体活动。本研究使用了青少年大脑与认知发展研究的一个样本，以阐明特定类型的屏幕媒体使用、大脑发育和各种心理健康问题之间的纵向关联。结果表明，不同类型的屏幕媒体使用与心理健康问题、皮层下体积和皮层-皮层下连接性存在不同的关联。具体而言，更多地被动使用媒体与违规行为增加有关，而更多地玩电子游戏与退缩/抑郁症状增加有关。此外，更多地使用社交媒体与海马体、尾状核和丘脑体积减小有关。需要更多研究来检验屏幕媒体使用对青少年神经发育过程和心理健康问题的不同影响。
