Social media has created a new social landscape for adolescents. Knowledge is needed on how this landscape shapes adolescents’ social skills and time spent with friends, as these outcomes are important to mental health and psychosocial functioning. Using five waves of biennially collected data from a birth cohort assessed throughout age 10–18 years (n = 812), we found that increased social media use predicted more time with friends offline but was unrelated to future changes in social skills. Age and sex did not moderate these associations but increased social media use predicted declined social skills among those high in social anxiety symptoms. The findings suggest that social media use may neither harm nor benefit the development of social skills and may promote, rather than displace, offline interaction with friends during adolescence. However, increased social media use may pose a risk for reduced social skills in socially anxious individuals.

新的社会格局：10-18 岁社交媒体使用、社交技能和线下友谊之间的关系

社交媒体为青少年创造了新的社会景观。我们需要了解这种情况如何影响青少年的社交技能和与朋友相处的时间，因为这些结果对心理健康和心理社会功能很重要。通过对 10 至 18 岁出生队列（n = 812）每两年收集的五波数据进行评估，我们发现社交媒体使用的增加预示着与朋友离线相处的时间增多，但与未来社交技能的变化无关。年龄和性别并没有调节这些关联，但社交媒体使用的增加预示着社交焦虑症状严重的人的社交技能会下降。研究结果表明，社交媒体的使用既不会损害也不会有益于社交技能的发展，并且可能会促进而不是取代青春期与朋友的线下互动。然而，社交媒体使用的增加可能会导致社交焦虑者的社交技能下降。
