消极的紧迫感，自我报告的倾向，冲动的行为时，痛苦，增加非自杀性自我伤害（NSSI）的风险。NSSI还与受损的消极情绪反应抑制（NERI）有关，特别是消极情绪行动终止（NEAT），这是一种理论上与消极紧迫感有关的认知过程。我们以前发现，在情绪停止信号任务中，有NSSI历史的成年人很难抑制对描绘负面内容的情感图像（但不是积极或中性图像）的行为反应。我们试图复制这一发现，确定这种缺陷是否延伸到消极情绪行为抑制（NEAS; NERI的早期阶段），并探讨这两个阶段的情绪反应抑制是否有助于解释消极紧迫感和NSSI之间的关系。88名有NSSI病史的成年人（n = 45）和没有NSSI病史或精神病理学的健康对照参与者（n = 43）完成了临床访谈、症状清单、冲动性问卷调查以及早期和晚期NERI（分别为NEAS和NEAT）的行为测定。在情绪停止信号任务中，NSSI组的NEAT比对照组更差，但在情绪去/不去任务中没有观察到NEAS的组间差异。然而，NERI的早期和晚期都是负紧迫感的独立变量。我们还发现，NEAT解释了负紧迫感和NSSI之间的关联的方差。这些结果表明，在NSSI的冲动行为可能涉及具体受损的抑制控制发起的负面情绪冲动。这种对负面情绪刺激的延迟反应抑制的缺陷可能反映了自我伤害者的认知机制或途径，从而提高了负面紧迫感。
Negative urgency, the self-reported tendency to act impulsively when distressed, increases risk for nonsuicidal selfinjury (NSSI). NSSI is also associated with impaired negative emotional response inhibition (NERI), specifically negative emotional action termination (NEAT), a cognitive process theoretically related to negative urgency. We previously found that adults with NSSI history had difficulty inhibiting behavioral responses to affective images depicting negative content (but not positive or neutral images) in an Emotional Stop-Signal Task. We sought to replicate this finding, determine whether this deficit extends to negative emotional action suppression (NEAS; an earlier stage of NERI), and explore whether impairment in these two stages of emotional response inhibition helps explain the relationship between negative urgency and NSSI. Eighty-eight adults with NSSI history (n = 45) and healthy control participants (n = 43) without NSSI history or psychopathology completed a clinical interview, symptom inventories, an impulsivity questionnaire, and behavioral assays of early and late NERI (NEAS and NEAT, respectively). The NSSI group had worse NEAT than the control group in the Emotional Stop-Signal Task, but no group differences in NEAS were observed in an Emotional Go/No-go task. However, both early and late stages of NERI accounted for independent variance in negative urgency. We additionally found that NEAT explained variance in the association between negative urgency and NSSI. These results suggest that impulsive behavior in NSSI may involve specifically impaired inhibitory control over initiated negative emotional impulses. This deficit in late response inhibition to negative emotional stimuli might reflect a cognitive mechanism or pathway to elevated negative urgency among people who self-injure.
