非自杀性自我伤害(NSSI)是指在没有自杀意图的情况下故意破坏自己的身体组织(例如，割伤或烧伤皮肤)。以前的研究发现，有NSSI病史的人表现出的痛觉减弱。然而，目前还不清楚为什么会出现这种效应。在目前的研究中，我们使用了有(n=25)和没有(n=47)NSSI病史的参与者的样本来检验这一假设，即情绪失调部分解释了NSSI与痛觉减弱相关的原因。疼痛感知被量化为在冷加压任务期间评估的痛阈值、疼痛耐受性和疼痛强度等级。非自杀性自我伤害与情绪失调增加和痛觉减弱有关。结果表明，情绪调节失调与两组中疼痛感觉的减弱相关，这表明无论NSSI病史如何，这种关联都存在。结果还指出，情绪失调部分解释了NSSI和疼痛耐受性之间的联系，但不能解释其他疼痛变量。总体而言，结果与情绪失调可能增加NSSI风险的假设是一致的，这在一定程度上是通过增加体验自我伤害所涉及的痛苦的意愿来实现的。需要研究来更直接地研究这一假说。(C)2012 Elsevier Inc.保留所有权利。
Nonsuicidal self-injury (NSSI) is the deliberate destruction of one's own body tissue in the absence of suicidal intent (e.g., cutting or burning the skin). Previous studies have found that people with a history of NSSI display diminished pain perception. However, it remains unclear why this effect occurs. In the present study, we used a sample of participants with (n = 25) and without (n = 47) a history of NSSI to test the hypothesis that emotion dysregulation partially explains why NSSI is associated with diminished pain perception. Pain perception was quantified as pain threshold, pain tolerance, and pain intensity ratings assessed during the cold pressor task. Nonsuicidal self-injury was associated with increased emotion dysregulation and diminished pain perception. Results showed that emotion dysregulation was correlated with diminished pain perception within both groups, demonstrating that this association exists regardless of NSSI history. Results also specified that emotion dysregulation partially accounted for the association between NSSI and pain tolerance but not other pain variables. Overall, results were consistent with the hypothesis that emotion dysregulation may increase NSSI risk in part by increasing the willingness to experience the pain involved in self-injury. Studies are needed to more directly investigate this hypothesis. (C) 2012 Elsevier Inc. All rights reserved.
