概括

患有非自杀性自我伤害 (NSSI) 的人经常在行为过程中经历疼痛,这与止痛模型相反. 在NSSI期间,情绪疼痛减少,解离与疼痛减少有关,而严重程度和自我惩罚动机与更大的疼痛相关.

科学领域:

心理学心理学心理学
临床心理学临床心理学
心理病理学心理病理学

背景情况:

非自杀性自我伤害 (NSSI) 模型提出疼痛的作用是通过开始,抵消或止痛.
有限的研究同时测试了这些模型或探索了NSSI疼痛体验因素.

研究的目的:

在一个大样本中检查NSSI期间的疼痛经历.
调查NSSI特征,边缘性人格障碍 (BPD) 特征,情绪疼痛,分离和NSSI疼痛之间的关联.
测试有关NSSI疼痛影响因素的假设,包括自我惩罚动机.

主要方法:

在1630名有NSSI病史的个人中进行了在线调查.
在NSSI期间对疼痛的描述性分析.
测试NSSI频率/严重程度,BPD特征,情绪疼痛,分离,自我惩罚动机和NSSI疼痛经历之间的关联的假设.

主要成果:

疼痛缓解是罕见的 (4.3%);大多数参与者在NSSI期间报告疼痛.
在NSSI期间和之后,情绪疼痛显著减少.
在NSSI期间较高的解离与较少的疼痛相关.
NSSI严重程度,NSSI前的情绪疼痛和自我惩罚动机与更大的NSSI疼痛有关.
NSSI频率和BPD特征与NSSI疼痛没有直接关联,但BPD特征调节了其他关系.

结论:

这些发现挑战了NSSI的简单止痛或疼痛补偿模型.
个人可能会从事NSSI来经历疼痛,尽管可能会增加疼痛耐受性.
情绪疼痛,分离和自我惩罚动机的相互作用显著影响了NSSI期间经历的疼痛.
