Borderline personality disorder (BPD) is a highly comorbid disorder, and these comorbidities increase the impairment associated with BPD. For example, depression, which occurs in the majority of individuals with BPD, increases the likelihood of an individual with BPD to engage in nonsuicidal self-injury (NSSI). Little research, however, has investigated potential mechanisms of NSSI engagement in this population. The current study aimed to fill this gap by examining momentary experiences, levels of distress tolerance, and NSSI among 51 individuals meeting current diagnostic criteria for BPD and a comorbid depressive disorder. Using data from an ecological momentary assessment across 7 days, it was found that daily urges to hurt oneself and impulsive urges, but not daily negative affect or aggressive urges, predicted NSSI occurrence. Furthermore, low levels of distress tolerance was a stronger predictor of NSSI behavior than daily experiences. These findings have important implications with regard to state versus trait dispositions in NSSI engagement among those with BPD and depression.
边缘型人格障碍（BPD）是一种高度共病的疾病，这些共病会增加与BPD相关的损害。例如，大多数BPD患者会出现的抑郁，会增加BPD患者进行非自杀性自伤（NSSI）的可能性。然而，很少有研究调查该人群中NSSI行为的潜在机制。当前的研究旨在通过检查51名符合BPD和共病抑郁障碍当前诊断标准的个体的即时体验、痛苦耐受力水平和NSSI行为来填补这一空白。使用来自7天的生态瞬时评估的数据，研究发现，每日的自我伤害冲动和冲动性冲动，而非每日的消极情绪或攻击冲动，可预测NSSI行为的发生。此外，与日常体验相比，低痛苦耐受力是NSSI行为更强的预测因素。这些发现对于BPD和抑郁症患者NSSI行为中的状态与特质倾向具有重要意义。
