背景资料：尽管越来越多的证据表明创伤后应激障碍（PTSD）和自我伤害行为（SIB）之间的关系，有限的研究已经检查了可能缓和PTSD和非自杀性SIB（故意自我伤害; DSH）和自杀性SIB（自杀企图）之间的关联的因素。然而，研究表明，创伤性事件的特征，共同发生的边缘性人格障碍（BPD）和情绪失调可能会影响PTSD和SIB之间的关系。因此，本研究的目的是检查这些因素在PTSD和SIB之间的关联中的调节作用（包括DSH和自杀企图的历史和频率，以及DSH的多功能性）在有（n=116）和没有（n=130）PTSD历史的物质使用障碍住院患者样本中的差异。逐步回归分析的结果表明，性攻击相关的PTSD预测自杀企图的频率和DSH的多功能性PTSD。此外，分层线性和逻辑回归分析的结果表明，共同发生的BPD温和的PTSD和DSH的历史和多功能性和情绪失调温和的PTSD和DSH频率之间的关系。具体而言，PTSD和DSH结果之间的关系在同时发生BPD和情绪失调水平较高的参与者中更强。局限性：本研究受限于其对横断面自我报告数据的依赖。尽管存在局限性，研究结果表明自杀未遂和DSH存在不同的风险因素，并强调了在评估创伤后应激障碍中SIB风险时，检查创伤特征、相关BPD和情绪失调的重要性。(C)2014爱思唯尔有限公司版权所有。
Background: Despite increasing evidence for a relation between posttraumatic stress disorder (PTSD) and self-injurious behaviors (SIB), limited research has examined the factors that may moderate the associations between PTSD and both nonsuicidal SIB (deliberate self-harm; DSH) and suicidal SIB (suicide attempts). Nonetheless, research suggests that characteristics of the traumatic event, co-occurring borderline personality disorder (BPD), and emotion clysregulation may influence the relations between PTSD and SIB.Methods: Thus, the aim of this study was to examine the moderating role of these factors in the association between PTSD and SIB (including history and frequency of DSH and suicide attempts, and DSH versatility) among a sample of substance use disorder inpatients with (n=116) and without (n=130) a history of PTSD.Results: Results from stepwise regression analyses indicate that sexual assault-related PTSD predicted suicide attempt frequency and DSH versatility among those with PTSD. Furthermore, results from hierarchical linear and logistic regression analyses suggest that co-occurring BPD moderates the relationship between PTSD and both DSH history and versatility and emotion dysregulation moderates the relationship between PTSD and DSH frequency. Specifically, the relations between PTSD and DSH outcomes were stronger among participants with co-occurring BPD and higher levels of emotion dysregulation.Limitations: This study is limited by its reliance on cross-sectional, self report data.Conclusions: Despite limitations, findings suggest distinct risk factors for suicide attempts and DSH, and highlight the importance of examining characteristics of the trauma and associated BPD and emotion dysregulation in assessing risk for SIB in PTSD.
