抑郁症是全球主要的公共卫生问题。有证据表明，社会支持和友谊会影响心理健康，对推动抑郁症的社会过程的更好理解有可能带来显着的公共卫生效益。我们调查了青少年社交网络上的情绪传播，通过不事先假设传播的是情绪低落还是健康情绪，我们的模型具有灵活性。在这里，我们表明，虽然抑郁症不会传播，但朋友之间的健康情绪与显着降低发展风险和增加从抑郁症中恢复的机会有关。我们发现，这种健康情绪的传播可以使用非线性复杂传染模型来捕获。在青少年的社交网络中，拥有足够多的健康情绪的朋友可以在6-12个月的时间内将患抑郁症的可能性减半，或从抑郁症中恢复的可能性增加一倍。我们的研究结果表明，促进青少年之间的友谊可以降低抑郁症的发生率和患病率。
Depression is a major public health concern worldwide. There is evidence that social support and befriending influence mental health, and an improved understanding of the social processes that drive depression has the potential to bring significant public health benefits. We investigate transmission of mood on a social network of adolescents, allowing flexibility in our model by making no prior assumption as to whether it is low mood or healthy mood that spreads. Here, we show that while depression does not spread, healthy mood among friends is associated with significantly reduced risk of developing and increased chance of recovering from depression. We found that this spreading of healthy mood can be captured using a non-linear complex contagion model. Having sufficient friends with healthy mood can halve the probability of developing, or double the probability of recovering from, depression over a 6–12-month period on an adolescent social network. Our results suggest that promotion of friendship between adolescents can reduce both incidence and prevalence of depression.
