在评估情绪反应抑制的情绪停止信号任务中的表现与消极紧迫感和精神病理，特别是自我伤害行为有关。事实上，在情绪停止信号任务中，难以抑制对厌恶刺激的阳性负面反应（即不良的负面情绪反应抑制）部分解释了消极紧迫感与非自杀性自伤之间的联系。在这里，我们结合了来自临床（住院精神病患者）和非临床（社区/学生参与者）样本的现有数据集，年龄在18-65岁（N = 450），以检查该行为任务的心理测量特性，并评估情绪停止信号任务指标与完成UPPS-P的参与者（N = 223）的不同冲动特征相关的假设。我们特别预测了更严重的负面情绪反应抑制（即在停止信号试验中代表对不愉快图像的负面反应的委托错误）和负面紧迫性之间的关联，而对积极刺激的委托错误-反映更严重的积极情绪反应抑制-将与积极紧迫性相关。结果支持情绪停止信号任务的收敛效度和区别效度：正如假设的那样，不良的消极情绪反应抑制与UPPS-P上的消极紧迫性和其他冲动特征特异性相关。然而，我们没有发现积极情绪反应抑制与积极紧迫感之间的假设关联。与其他行为任务类似，情绪停止信号任务表现与自我报告测量之间的相关性不大。完成两次情绪停止信号任务的参与者（n = 61）为重测信度提供了初步证据。总之，研究结果表明，情绪停止信号任务具有足够的可靠性和有效性，可以得出与负性紧迫感和精神病理相关的神经认知功能的候选行为标记。
Performance on an emotional stop-signal task designed to assess emotional response inhibition has been associated with Negative Urgency and psychopathology, particularly self-injurious behaviors. Indeed, difficulty inhibiting prepotent negative responses to aversive stimuli on the emotional stop-signal task (i.e. poor negative emotional response inhibition) partially explains the association between Negative Urgency and non-suicidal self-injury. Here, we combine existing data sets from clinical (hospitalised psychiatric inpatients) and non-clinical (community/student participants) samples aged 18–65 years (N = 450) to examine the psychometric properties of this behavioural task and evaluate hypotheses that emotional stop-signal task metrics relate to distinct impulsive traits among participants who also completed the UPPS-P (n = 223). We specifically predicted associations between worse negative emotional response inhibition (i.e. commission errors during stop-signal trials representing negative reactions to unpleasant images) and Negative Urgency, whereas commission errors to positive stimuli – reflecting worse positive emotional response inhibition – would relate to Positive Urgency. Results support the emotional stop-signal task’s convergent and discriminant validity: as hypothesised, poor negative emotional response inhibition was specifically associated with Negative Urgency and no other impulsive traits on the UPPS-P. However, we did not find the hypothesised association between positive emotional response inhibition and Positive Urgency. Correlations between emotional stop-signal task performance and self-report measures were the modest, similar to other behavioural tasks. Participants who completed the emotional stop-signal task twice (n = 61) additionally provide preliminary evidence for test–retest reliability. Together, findings suggest adequate reliability and validity of the emotional stop-signal task to derive candidate behavioural markers of neurocognitive functioning associated with Negative Urgency and psychopathology.
