Research investigating the social context of adolescent nonsuicidal self-injury (NSSI) has been limited. We therefore examined social characteristics of NSSI, such as knowledge of friends' NSSI and the role friends play in continuing NSSI, and their relationships to other known NSSI correlates, such as suicidality.
We assessed NSSI characteristics, including social features, in a community sample of 89 self-injuring adolescents. We also assessed psychosocial correlates of NSSI, including impulsivity, self-concept, and psychiatric symptoms.
Knowledge of friends' NSSI was relatively common among self-injurers. In addition, knowledge of friends' NSSI was associated with use of more NSSI methods, cutting behaviors, and suicidal ideation, but not with other NSSI correlates. However, teaching or encouragement of NSSI by friends was rare.
Knowledge of friends' NSSI may serve as marker of increased severity among adolescent self-injurers. These findings have implications for identifying and intervening with high-risk self-injuring youth.
对青少年非自杀性自伤（NSSI）社会背景的研究有限。因此，我们研究了 NSSI 的社会特征，例如朋友 NSSI 的知识以及朋友在继续 NSSI 中所扮演的角色，以及它们与其他已知 NSSI 相关因素（如自杀倾向）的关系。
我们评估了 89 名自我伤害青少年的 NSSI 特征，包括社会特征。我们还评估了 NSSI 的心理社会相关因素，包括冲动性、自我概念和精神症状。
在自我伤害者中，朋友 NSSI 的知识相对普遍。此外，朋友 NSSI 的知识与使用更多的 NSSI 方法、切割行为和自杀意念有关，但与其他 NSSI 相关因素无关。然而，朋友对 NSSI 的教导或鼓励很少见。
朋友 NSSI 的知识可能是青少年自我伤害者严重程度增加的标志。这些发现对识别和干预高危自我伤害青少年具有重要意义。
