Nonsuicidal self-injury (NSSI) and borderline personality disorder (BPD) are serious mental health problems that may have common developmental pathways. Adverse childhood environments coupled with trait impulsivity and emotion dysregulation purportedly increase the risk of NSSI and BPD. The primary aim of this study was to examine the association of these risk factors with NSSI and BPD over a 1-year period among young adults (N = 229; aged 18-35; 75.5% female). Participants completed measures of relevant variables at baseline and every 3 months over 12 months. Hypotheses were that emotion regulation difficulties would mediate the association of childhood maltreatment with NSSI and BPD and that impulsivity would moderate the association of childhood maltreatment with ERD. Findings from multilevel modelling analyses indicated that emotion regulation difficulties mediated the association of childhood maltreatment with both NSSI and BPD. Contrary to hypotheses, impulsivity did not moderate the association of childhood maltreatment with emotion regulation difficulties. These findings highlight the importance of emotion regulation difficulties in NSSI and BPD among young adults.
非自杀性自伤（NSSI）和边缘型人格障碍（BPD）是严重的心理健康问题，可能具有共同的发展路径。据称，不良的童年环境加上特质冲动性和情绪调节障碍会增加非自杀性自伤和边缘型人格障碍的风险。本研究的主要目的是在一年时间内，考察这些风险因素与年轻人（N = 229；年龄在18 - 35岁之间；75.5%为女性）非自杀性自伤和边缘型人格障碍之间的关联。参与者在基线时以及在12个月内每3个月完成一次相关变量的测量。研究假设为，情绪调节困难将介导童年期虐待与非自杀性自伤和边缘型人格障碍之间的关联，并且冲动性将调节童年期虐待与情绪调节障碍之间的关联。多层次建模分析的结果表明，情绪调节困难介导了童年期虐待与非自杀性自伤和边缘型人格障碍之间的关联。与假设相反，冲动性并未调节童年期虐待与情绪调节困难之间的关联。这些发现凸显了情绪调节困难在年轻人非自杀性自伤和边缘型人格障碍中的重要性。
