The current study aims to examine the causal effect of boredom on non-suicidal self-injury (NSSI), expanding prior experimental research by including an anger induction to compare to a boredom induction, and additionally measuring whether participants specifically seek painful stimulation. In a sample of mostly undergraduate students (N = 146), emotional state was manipulated through video induction, and NSSI behavior was simultaneously measured, operationalized through self-administration of electric shocks. Participants’ pain thresholds were measured beforehand. NSSI history and negative urgency were included as potential moderators. Results showed that boredom increased both frequency and intensity of self-administered electric shocks, especially in participants with an NSSI history. Negative urgency was not a significant moderator. No causal anger-NSSI link was found, possibly due to the anger induction not being sufficiently effective. Clinical implications are considered through suggestions of boredom coping skills training as an intervention strategy in NSSI populations.

目前的研究旨在检查无聊对非自杀性自伤 (NSSI) 的因果影响，通过包括愤怒诱导以与无聊诱导进行比较来扩展先前的实验研究，并额外测量参与者是否特别寻求痛苦刺激。在一个以本科生为主的样本中（N = 146），情绪状态通过视频感应来控制，同时测量 NSSI 行为，通过自我电击来操作。事先测量了参与者的疼痛阈值。NSSI 历史和消极紧迫性被包括为潜在的调节者。结果表明，无聊会增加自我电击的频率和强度，尤其是在有 NSSI 病史的参与者中。消极的紧迫感不是一个重要的调节因素。没有发现因果愤怒-NSSI 链接，可能是由于愤怒诱导不够有效。通过将无聊应对技能培训作为 NSSI 人群的干预策略的建议来考虑临床意义。
