Poor interpersonal relationships are one of the risk factors for non-suicidal self-injury (NSSI) and suicidal behaviors among adolescents. Previous studies have mostly focused on a single interpersonal perspective, and it remains uncertain how the cumulative interpersonal risk across time and domains interacts with NSSI and suicide. The current study employed cross-lagged panel models (CLPM) and random intercept cross-lagged panel models (RI-CLPM) to investigate the interaction among cumulative interpersonal risk, NSSI, and suicide attempts at both the between-person and within-person levels, while examining sex differences in these relationships. A total of 1038 Chinese adolescents (47.0% girls; baseline M = 12.35 years, SD = 0.52) participated in a four-wave longitudinal survey with 6-months intervals. The results showed that at the between-person level, there were reciprocal predictive relationships between cumulative interpersonal risk, NSSI and suicide attempts. At the within-person level, changes in NSSI affected changes in cumulative interpersonal risk, and suicide attempts exhibited a reciprocal relationship with cumulative interpersonal risk and NSSI, with significant sex differences observed. These findings underscore the stable and trait-like associations between cumulative interpersonal risk, NSSI and suicide attempts. Given these findings, to reduce the occurrence of suicide among adolescents, it is essential to target interventions aimed tat enhancing their interpersonal adaptability.
人际关系不佳是青少年非自杀性自伤（NSSI）和自杀行为的风险因素之一。以往的研究大多集中在单一的人际关系视角，而随着时间推移和不同领域的累积人际风险如何与NSSI和自杀相互作用仍不明确。本研究采用交叉滞后面板模型（CLPM）和随机截距交叉滞后面板模型（RI-CLPM），在个体间和个体内水平上研究累积人际风险、NSSI和自杀未遂之间的相互作用，同时考察这些关系中的性别差异。共有1038名中国青少年（47.0%为女孩；基线年龄M = 12.35岁，标准差SD = 0.52）参与了一项为期4波、间隔6个月的纵向调查。结果表明，在个体间水平上，累积人际风险、NSSI和自杀未遂之间存在相互预测关系。在个体内水平上，NSSI的变化影响累积人际风险的变化，自杀未遂与累积人际风险和NSSI呈现相互关系，且存在显著的性别差异。这些发现强调了累积人际风险、NSSI和自杀未遂之间稳定的、类似特质的关联。基于这些发现，为减少青少年自杀的发生，针对提高他们人际适应能力的干预措施至关重要。
