Background: Nonsuicidal self-injury (NSSI) is a strong predictor of suicide attempts (SA). Characteristics of NSSI have been shown to influence the NSSI-SA relationship; however, the temporal nature of this association is understudied. Aims: This study aimed to elucidate the NSSI-SA relationship by examining the association between NSSI characteristics and time lapsed from NSSI onset to first SA. Method: Participants were 111 individuals with a history of NSSI that preceded their first SA who completed a series of self-report measures. Results: NSSI methods of cutting and burning, and the anti-dissociation function, were associated with a shorter transition time from NSSI to SA. Earlier age of NSSI onset and the interpersonal boundaries function were related to a longer time to transition. Limitations: This sample size was limited, and data were collected cross-sectionally. Conclusion: Findings provide foundational knowledge regarding NSSI characteristics to inform theoretical models of the NSSI-SA association. This information can inform suicide risk assessments among those with a history of NSSI.

检查从非自杀性自伤到自杀未遂的过渡时间。

背景：非自杀性自伤 (NSSI) 是自杀企图 (SA) 的强预测因子。NSSI 的特征已被证明会影响 NSSI-SA 关系；然而，这种关联的时间性质尚未得到充分研究。目的：本研究旨在通过检查 NSSI 特征与从 NSSI 发病到第一次 SA 的时间间隔之间的关联来阐明 NSSI-SA 关系。方法：参与者是 111 名在第一次 SA 之前有 NSSI 病史的人，他们完成了一系列自我报告措施。结果：NSSI 的切割和燃烧方法以及抗解离功能与从 NSSI 到 SA 的较短过渡时间相关。NSSI 发病年龄较早和人际边界功能与较长的过渡时间有关。局限性：这个样本量是有限的，和数据是横断面收集的。结论：研究结果提供了关于 NSSI 特征的基础知识，为 NSSI-SA 协会的理论模型提供信息。这些信息可以为有 NSSI 病史的人的自杀风险评估提供信息。
