Concerns have been raised that social media use causes mental health problems in adolescents, but findings are mixed, and effects are typically small. The present inquiry is the first to measure diagnostically-defined symptoms of depression and anxiety, examining whether changes in social media behavior predict changes in levels of symptoms from age 10 to 16, and vice versa. We differentiate between activity related to one's own vs. others' social media content or pages (i.e., self-oriented: posting updates, photos vs other-oriented: liking, commenting).
A birth-cohort of Norwegian children was interviewed about their social media at ages 10, 12, 14 and 16 years ( = 810). Symptoms of depression, social anxiety and generalized anxiety were captured by psychiatric interviews and data was analyzed using Random Intercept Cross-lagged Panel Modeling.
Within-person changes in self- and other oriented social media behavior were unrelated to within-person changes in symptoms of depression or anxiety two years later, and vice versa. This null finding was evident across all timepoints and for both sexes.
The frequency of posting, liking, and commenting is unrelated to future symptoms of depression and anxiety. This is true also when gold standard measures of depression and anxiety are applied.
人们担心青少年使用社交媒体会导致心理健康问题，但研究结果不一，且影响通常较小。本研究首次对诊断明确的抑郁和焦虑症状进行测量，考察从10岁到16岁社交媒体行为的变化是否能预测症状水平的变化，反之亦然。我们区分了与自己或他人的社交媒体内容或页面相关的活动（即自我导向：发布更新、照片与他人导向：点赞、评论）。
对挪威儿童出生队列在10岁、12岁、14岁和16岁时进行关于社交媒体使用情况的访谈（n = 810）。通过精神科访谈获取抑郁、社交焦虑和广泛性焦虑症状，并使用随机截距交叉滞后面板模型分析数据。
自我导向和他人导向的社交媒体行为的个体内变化与两年后抑郁或焦虑症状的个体内变化无关，反之亦然。这一零结果在所有时间点和两性中均很明显。
发布、点赞和评论的频率与未来的抑郁和焦虑症状无关。在应用抑郁和焦虑的金标准测量时也是如此。
