Abstract

Objective

Although once considered a defining feature of borderline personality disorder, research has found high rates of NSSI among individuals with other psychiatric disorders, particularly posttraumatic stress disorder (PTSD) and depressive disorders. A recent study from our research team found that lifetime PTSD and depressive disorders were associated with unique self-reported NSSI motives. Given well-established limitations of assessing motives via self-report measures, the present study sought to extend this line of research by using a novel laboratory measure of the implicit NSSI-relief association to examine NSSI emotional relief motives.

Method

A subset of participants from our previous study (N = 109) completed diagnostic interviews and the laboratory-based DSH-Relief Implicit Association Test (IAT).

Results

Findings indicated that individuals with lifetime PTSD evidenced stronger NSSI-relief associations than those without PTSD. Further, this main effect was qualified by a PTSD by depressive disorder interaction, such that stronger NSSI-relief associations were found among individuals with lifetime PTSD but no lifetime depressive disorder than among individuals without a history of either PTSD or a depressive disorder.

Conclusions

Results highlight the importance of investigating NSSI motives associated with different symptom profiles using a multi-method approach.

非自杀性自伤与创伤后应激障碍和抑郁症缓解的隐性关联*

摘要

客观的

尽管曾经被认为是边缘型人格障碍的一个决定性特征，但研究发现，在患有其他精神疾病，特别是创伤后应激障碍 (PTSD) 和抑郁症的个体中，NSSI 的发生率很高。我们研究团队最近的一项研究发现，终生 PTSD 和抑郁症与独特的自我报告的 NSSI 动机有关。鉴于通过自我报告措施评估动机的既定局限性，本研究试图通过使用隐式 NSSI 救济关联的新实验室测量来检查 NSSI 情绪缓解动机来扩展这一研究方向。

方法

我们之前研究的一部分参与者 ( N  = 109) 完成了诊断访谈和基于实验室的 DSH-Relief 内隐关联测试 (IAT)。

结果

研究结果表明，与没有 PTSD 的人相比，患有终生 PTSD 的人表现出更强的 NSSI 缓解关联。此外，这种主要影响通过抑郁障碍相互作用的 PTSD 来限定，因此在终生 PTSD 但没有终生抑郁障碍的个体中发现比没有 PTSD 或抑郁障碍病史的个体更强的 NSSI 缓解关联。

结论

结果强调了使用多方法研究与不同症状特征相关的 NSSI 动机的重要性。
