屏幕媒体的使用与青少年的心理健康问题有关。然而，很少有研究使用同期时间日记（而不是回顾性报告）来检查屏幕媒体的使用，比较特定屏幕媒体活动或性别之间的关联，或检查与自残行为的关联。参与者是 2015 年千禧队列研究（一项针对英国青少年的全国代表性出生队列研究）中在一个工作日和一个周末完成时间日记的 13 至 15 岁青少年 (n = 4,252)。参与者还完成了抑郁症状的测量，并报告了他们去年是否有过自残行为。与每天花在数字媒体上的时间少于 2 小时相比，每天花在数字媒体上的时间超过 2 小时的女孩更有可能发生自残（对于社交媒体使用，调整后的自残相对风险 [ARR] = 1.46，95% CI = 1.17, 1.82；对于互联网使用，ARR = 1.80 [1.20, 2.70]）。在数字媒体上花费更多时间的女孩也更有可能感到抑郁（对于社交媒体，ARR = 1.29 [1.03, 1.63]；对于互联网使用，ARR = 1.75 [1.19, 2.59]）。女孩与游戏、发短信/电子邮件和观看电视/视频的关联大多不显着。男孩的关联大多不显着。每天使用数字媒体（尤其是社交媒体和互联网）时间越多的女孩更有可能出现临床上显着的抑郁症状和自残史，尽管玩游戏、发短信/电子邮件和观看电视/视频几乎没有关联。屏幕媒体的使用大多与男孩的自残或抑郁没有显着相关。
Screen media use is associated with mental health problems among adolescents. However, few studies have examined screen media use using contemporaneous time diaries (rather than retrospective reports), compared associations across specific screen media activities or by gender, or examined associations with self-harm behaviors. Participants were 13- to 15-year-old adolescents completing time diaries (n = 4,252) for one weekday and one weekend day in the 2015 administration of the Millennium Cohort Study, a nationally representative birth cohort study of UK adolescents. Participants also completed a measure of depressive symptoms and reported whether they had engaged in self-harm in the last year. Girls who spent 2 + hrs/day, compared to < 2 h/day, on digital media were more likely to self-harm (for social media use, adjusted relative risk [ARR] for self-harm = 1.46, 95% CI = 1.17, 1.82; for internet use, ARR = 1.80 [1.20, 2.70]). Girls spending more time on digital media were also more likely to be depressed (for social media, ARR = 1.29 [1.03, 1.63]; for internet use, ARR = 1.75 [1.19, 2.59]). Associations with gaming, texting/e-mailing, and TV/video watching among girls were mostly not significant. Associations for boys were mostly not significant. Girls who use digital media (especially social media and the internet) more hrs/day are more likely to have clinically significant levels of depressive symptoms and prior history of self-harm, though gaming, texting/e-mailing, and TV/video watching showed few associations. Screen media use was mostly not significantly associated with self-harm or depression among boys.
