This study examined direct and indirect forms of peer socialization of non-suicidal self-injury (NSSI) in adolescent friendship networks. Data were collected among 348 adolescents (55% females; = 15.02 years; = 0.53) at 4 assessment waves. Stochastic actor-based models revealed no evidence for direct socialization of NSSI: adolescents whose friends reported higher NSSI did not increase their NSSI over time. However, indirect forms of socialization were found. After controlling for direct socialization and selection effects, friends' depressive symptoms predicted changes in male and female adolescents' NSSI and friends' impulsivity predicted changes in male adolescents' NSSI. Findings highlight the importance of extending peer influence research beyond the classical "modeling" paradigm by providing evidence that peers may indirectly socialize adolescents' NSSI.
本研究考察了青少年友谊网络中同伴对非自杀性自伤（NSSI）的直接和间接社交化形式。在4次评估浪潮中收集了348名青少年（55%为女性；平均年龄 = 15.02岁；标准差 = 0.53）的数据。基于随机行为者的模型没有发现NSSI直接社交化的证据：朋友报告NSSI较高的青少年并不会随着时间的推移增加他们的NSSI。然而，发现了间接社交化形式。在控制了直接社交化和选择效应后，朋友的抑郁症状预测了男性和女性青少年NSSI的变化，朋友的冲动性预测了男性青少年NSSI的变化。研究结果强调了将同伴影响研究扩展到经典“模仿”范式之外的重要性，因为有证据表明同伴可能会间接促使青少年出现NSSI。
