People who engage in non-suicidal self-injury (NSSI) consistently report greater emotion reactivity and dysregulation than their peers. However, evidence that these self-reports reflect an amplified emotional response under controlled conditions is limited. Here we test the effects of both subtle and overt social exclusion, to determine whether self-reported emotion dysregulation reflects responses to real-time emotional challenge for people who self-injure. We recruited 100 young women with past-year NSSI and 100 without NSSI to an online experiment. Participants took part in a baseline social inclusion ball-tossing game, followed by either an overt or subtle social exclusion ball-tossing game, while we measured negative mood and belongingness. Despite reporting greater emotion reactivity ( = 1.40) and dysregulation ( = 1.63) than controls, women with past-year NSSI showed no differences in negative mood or belongingness ratings in response to either overt or subtle social exclusion. Within the NSSI group, exploratory analyses found greater endorsement of intrapersonal functions predicted greater negative mood following social exclusion ( = 0.19). Given that amplified emotional responding is central to prominent theoretical models of NSSI, findings highlight the need to better understand the divergence in findings between self-reported emotion dysregulation and real-time emotional responding among people who self-injure.
进行非自杀性自我伤害（NSSI）的人一直报告称，他们比同龄人具有更强的情绪反应性和情绪调节障碍。然而，这些自我报告反映在可控条件下放大的情绪反应的证据有限。在此，我们测试了微妙和明显的社会排斥的影响，以确定自我报告的情绪调节障碍是否反映了自我伤害者对实时情绪挑战的反应。我们招募了100名过去一年有NSSI经历的年轻女性和100名没有NSSI经历的年轻女性参与一项在线实验。参与者先参加了一个基线社会包容抛球游戏，随后进行明显或微妙的社会排斥抛球游戏，同时我们测量她们的负面情绪和归属感。尽管过去一年有NSSI经历的女性报告的情绪反应性（=1.40）和情绪调节障碍（=1.63）比对照组更强，但在面对明显或微妙的社会排斥时，她们在负面情绪或归属感评分上没有差异。在NSSI组内，探索性分析发现，对人际内功能的更多认同预示着社会排斥后有更强的负面情绪（=0.19）。鉴于增强的情绪反应是NSSI突出理论模型的核心，研究结果凸显了有必要更好地理解自我伤害者自我报告的情绪调节障碍与实时情绪反应之间研究结果的差异。
