虽然非自杀性自伤（NSSI）涉及自我造成的身体伤害，但许多自伤者报告在行为过程中感觉很少或没有疼痛。在这里，我们测试：（1）在成年自伤者中观察到的疼痛镇痛效果是否也存在于青少年中，（2）三个潜在的解释模型，提出习惯化，解离和/或自我批评有助于解释青少年中NSSI和疼痛镇痛之间的关联。参与者是从社区招募的79名青少年（12-19岁），他们参加了一项基于实验室的疼痛研究。结果显示，青少年自伤者比非自伤者有更高的痛阈和更强的疼痛耐受力。统计中介模型显示，习惯化和解离模型不支持，但是，自我批评的风格介导的关联NSSI和疼痛镇痛。目前的研究结果扩展了早期的工作，强调自我批评的风格可能有助于解释为什么自我伤害者表现出疼痛镇痛。具体来说，在应对压力事件时经历自我批评思想的倾向可能代表了第三个变量，增加了NSSI和疼痛镇痛的可能性。需要前瞻性的实验研究来复制和梳理这些关联的方向，并可能为开发这种危险行为问题的有效治疗方法提供有价值的线索。(C)2014爱思唯尔爱尔兰有限公司版权所有。
Although non-suicidal self-injury (NSSI) involves self-inflicted physical harm, many self-injurers report feeling little or no pain during the act. Here we test: (1) whether the pain analgesia effects observed among adult self-injurers are also present among adolescents, and (2) three potential explanatory models proposing that habituation, dissociation, and/or self-criticism help explain the association between NSSI and pain analgesia among adolescents. Participants were 79 adolescents (12-19 years) recruited from the community who took part in a laboratory-based pain study. Results revealed that adolescent self-injurers have a higher pain threshold and greater pain endurance than non-injurers. Statistical mediation models revealed that the habituation and dissociation models were not supported; however, a self-critical style does mediate the association between NSSI and pain analgesia. The present findings extend earlier work by highlighting that a self-critical style may help to explain why self-injurers exhibit pain analgesia. Specifically, the tendency to experience self-critical thoughts in response to stressful events may represent a third variable that increases the likelihood of both NSSI and pain analgesia. Prospective experimental studies are needed to replicate and tease apart the direction of these associations, and may provide valuable leads in the development of effective treatments for this dangerous behavior problem.
