Peer relationship plays an important role in non-suicidal self-injury (NSSI). However, little is known about how and in what conditions peer relationship may influence NSSI. By integrating multiple theories (i.e., attachment theory, the emotional regulation model of self-compassion and NSSI, and the differential-susceptibility theory), the current study investigated two potential mediators (i.e., self-compassion and depressive symptoms) and one potential moderator (i.e., behavioral impulsivity) of the relation between peer acceptance and NSSI. Participants were 813 Chinese adolescents (43% female; Mage at Wave 1 = 13.15 years) from a two-wave longitudinal study with data spanning one year. The results revealed that the indirect pathways linking peer acceptance and NSSI were conditioned on the level of behavioral impulsivity. Specifically, for adolescents with lower levels of impulsivity, a higher level of peer acceptance was related to fewer depressive symptoms directly or indirectly through self-compassion; fewer depressive symptoms, in turn, were linked to fewer NSSI behaviors longitudinally. For adolescents with higher levels of behavioral impulsivity, peer acceptance was related to fewer NSSI behaviors only through self-compassion. Results indicate that increasing peer acceptance is important in reducing adolescent NSSI. Interventions designed to reduce adolescent NSSI may also be effective if they focus on promoting adolescent self-compassion, particularly for adolescents with higher levels of behavioral impulsivity.
同伴关系在非自杀性自伤（NSSI）中起着重要作用。然而，对于同伴关系如何以及在何种条件下可能影响 NSSI，我们知之甚少。本研究整合了多种理论（即依恋理论、自我同情和 NSSI 的情绪调节模型以及差异易感性理论），探讨了同伴接纳与 NSSI 之间关系的两个潜在中介变量（即自我同情和抑郁症状）和一个潜在调节变量（即行为冲动性）。参与者为来自一项为期两年的纵向研究的 813 名中国青少年（43%为女性；第 1 波的平均年龄为 13.15 岁），数据跨越一年。结果表明，同伴接纳与 NSSI 之间的间接途径取决于行为冲动性的水平。具体来说，对于冲动性水平较低的青少年，较高的同伴接纳水平与较少的抑郁症状直接或间接相关，而自我同情则是通过较少的抑郁症状与较少的 NSSI 行为相关；对于冲动性水平较高的青少年，同伴接纳仅通过自我同情与较少的 NSSI 行为相关。研究结果表明，增加同伴接纳对于减少青少年 NSSI 很重要。如果干预措施侧重于促进青少年的自我同情，特别是针对冲动性水平较高的青少年，那么这些干预措施对于减少青少年 NSSI 可能也会有效。
