Non-suicidal self-injury (NSSI) is a major concern in both clinical and non-clinical populations. It has been approximated that 65-80% of individuals with borderline personality disorder (BPD) engage in some form of NSSI. Despite such high co-morbidity, much still remains unknown about the relationship between NSSI and BPD symptomatology. The goal of the current study was to identify individual BPD symptoms and higher order BPD factors that increase one's vulnerability of NSSI engagement among a college sample. It was hypothesized that the BPD factor of emotion dysregulation and the BPD symptoms of affect instability and intense anger/aggression would be associated with the presence and frequency of NSSI.
Seven hundred twenty four undergraduates (61.2% female) completed self-report measures of BPD symptomology and NSSI history.
Regression analyses revealed that among the individual BPD symptoms, past suicidality, impulsivity, chronic emptiness, and identity disturbance were each significantly, positively associated with lifetime history of NSSI, whereas unstable relationships were negatively associated with lifetime history of NSSI. The BPD symptom associated with NSSI frequency was dissociation. Among the BPD factors, emotion dysregulation and disturbed relatedness were both associated with NSSI history, but only disturbed relatedness was associated with NSSI frequency.
Findings show partial support for the importance of emotion dysregulation in the relationship between NSSI and BPD symptomatology, but also suggest that the relationship may be more complex and not solely based on emotion dysregulation.
非自杀性自伤（NSSI）是临床和非临床人群中一个主要关注点。据估计，边缘型人格障碍（BPD）患者中有 65-80%的人会以某种形式进行 NSSI。尽管这种共病率很高，但人们对 NSSI 与 BPD 症状之间的关系仍知之甚少。本研究的目的是确定个体 BPD 症状和更高阶的 BPD 因素，这些因素会增加大学生群体发生 NSSI 的易感性。研究假设 BPD 中情绪失调以及不稳定的情绪和强烈的愤怒/攻击性这两个因素与 NSSI 的发生和频率有关。
724 名本科生（61.2%为女性）完成了 BPD 症状和 NSSI 历史的自我报告测量。
回归分析显示，在个体 BPD 症状中，过去的自杀意念、冲动、慢性空虚和身份紊乱与 NSSI 的终生史显著正相关，而不稳定的人际关系与 NSSI 的终生史呈负相关。与 NSSI 频率相关的 BPD 症状是解离。在 BPD 因素中，情绪失调和人际关系紊乱都与 NSSI 历史有关，但只有人际关系紊乱与 NSSI 频率有关。
研究结果部分支持了情绪失调在 NSSI 与 BPD 症状之间关系中的重要性，但也表明这种关系可能更为复杂，不仅仅基于情绪失调。
