We examined the relation of interpersonal and media exposure to nonsuicidal self-injury (NSSI) among 340 university students in the southeastern United States (73.5% female, M age = 19.38 years, SD = 1.15). We also assessed interactions and main effects of each exposure and emotion dysregulation in relation to NSSI, testing the social learning hypothesis of NSSI. Most participants endorsed medium to high levels of exposure to NSSI via media sources. More than one-third of participants were somewhat or very familiar with someone who engaged in NSSI. Almost half reported occasional or frequent conversations about NSSI. Both exposure forms were significantly related to NSSI history. However, hurdle regression analyses revealed that interpersonal exposure and emotion dysregulation, but not media exposure, were significantly associated with NSSI history and frequency. We did not find evidence for an emotion dysregulation-by-interpersonal-exposure interaction. We discuss implications for theoretical models of NSSI, limitations, and future directions.
我们在美国东南部的340名大学生中研究了人际接触和媒体接触与非自杀性自伤（NSSI）之间的关系（73.5%为女性，平均年龄 = 19.38岁，标准差 = 1.15）。我们还评估了每种接触方式和情绪失调与NSSI的交互作用和主效应，检验了NSSI的社会学习假说。大多数参与者认可通过媒体渠道接触到中高水平的NSSI。超过三分之一的参与者对有过NSSI行为的人有些熟悉或非常熟悉。近一半的人报告偶尔或经常谈论NSSI。两种接触形式都与NSSI史显著相关。然而，门槛回归分析显示，人际接触和情绪失调与NSSI史和频率显著相关，而媒体接触则不然。我们没有找到情绪失调与人际接触之间存在交互作用的证据。我们讨论了对NSSI理论模型的启示、局限性和未来方向。
