The current study investigated the mechanisms underlying peer contagion of depressive symptoms in adolescence. Five annual measurements of data were gathered from a large (N = 842) community-based network of adolescents (M = 14.3 years at first measurement). Results showed that, after controlling for selection and deselection of friends on the basis of depressive symptoms, peers' depressive symptoms predicted increases in adolescents' depressive symptoms over time. Failure anticipation mediated effects of peers' depressive symptoms on adolescents' depressive symptoms, particularly for girls. Thus, results suggest that peers' depressive symptoms place adolescents at risk of developing depressive symptoms through increasing in failure anticipation.
本研究旨在探讨青少年抑郁症状同伴传染的作用机制。研究采用大样本（N = 842）社区青少年网络，收集了 5 年的年度数据（第一次测量时平均年龄为 14.3 岁）。结果表明，在控制基于抑郁症状的朋友选择和去选择后，同伴的抑郁症状可以预测青少年随时间推移抑郁症状的增加。失败预期中介了同伴抑郁症状对青少年抑郁症状的影响，对女孩的影响尤其明显。因此，研究结果表明，同伴的抑郁症状通过增加对失败的预期，使青少年面临发展出抑郁症状的风险。
