Recent scholarship has been divided on whether an observed increase in suicides in the United States among teenagers and preteens (12-18) can be attributed to an increased use in social screen media beginning in 2009. If these concerns are accurate effect sizes for the relationship between screen use and suicide should increase over the 16 years since 2001. The current study used the Florida Youth Risk Behavior Survey data (n = 45,992) from 2001 to 2017, to track effect sizes for screen/depression correlations, controlling for age and gender. A second dataset from the UK Understanding Society dataset (ns for each wave ranged between 3,536 and 4,850) was used to study associations between time spent on social media and emotional problems. Metaregression was be used to examine whether effect sizes increase across time. Results generally did not support the hypothesis that effect sizes between screen and social media use are increasing over time. Aside from the trends over time, for any given year, most effect sizes were below the r = .10 threshold used for interpretation with the exception of computer use which was just at that threshold. It is concluded that screens and social media use are unlikely to bear major responsibility for youth suicide trends.

自 2009 年以来,美国青少年和儿童(12-18 岁)自杀人数的增加是否可以归因于社交媒体屏幕使用的增加。如果这些担忧是准确的,那么屏幕使用与自杀之间的关系的效应大小应该会在自 2001 年以来的 16 年中增加。本研究使用了 2001 年至 2017 年佛罗里达州青少年风险行为调查数据(n=45992),通过控制年龄和性别,跟踪屏幕/抑郁相关性的效应大小。第二个数据集来自英国社会理解调查数据集(每个波次的 n 值在 3536 到 4850 之间),用于研究社交媒体使用时间与情绪问题之间的关联。元回归用于检验效应大小是否随时间增加。结果普遍不支持这样的假设,即屏幕和社交媒体使用之间的效应大小随时间增加。除了随时间的趋势外,在任何给定的年份,大多数效应大小都低于用于解释的 r=0.10 阈值,除了计算机使用,刚好在该阈值。结论是,屏幕和社交媒体的使用不太可能对青年自杀趋势负有主要责任。本文的视频摘要可在 https://www.youtube.com/watch?v=76S7cxiaU88 观看。
