冲动性是非自杀性自我伤害(NSSI)的一个重要概念。然而，关于冲动与NSSI之间的关系的研究却喜忧参半。本研究使用冲动性的多方面测量(即UPPS冲动性行为量表)和基于计算机的抑制控制的行为测量(即停止信号任务)来阐明这种关系。参与者是82名确认的自伤者和86名对照组，这些人是从大学人群中招募的。自我伤害者和控制者在停止信号任务上的表现相似。在UPPS上，自伤者最好的区别是紧迫感(在面临负面情绪时做出鲁莽的决定)，其次是缺乏预谋(无法为了计划而推迟行动)和寻求刺激(寻求刺激和冒险)。在自伤者中，缺乏毅力(无法坚持完成一项任务)预示着更近期和更频繁的NSSI。对概念和临床意义进行了讨论。
Impulsivity has been proposed as an important construct in nonsuicidal self-injury (NSSI). Yet, research on the relationship of impulsivity to NSSI has been mixed. The present study clarified this relationship using a multifaceted measure of impulsivity (i.e., UPPS Impulsive Behavior Scale), and a computer-based behavioral measure of inhibitory control (i.e., a stop-signal task). Participants were 82 confirmed self-injurers and 86 controls recruited from a college population. Self-injurers and controls performed similarly on the stop-signal task. On the UPPS, self-injurers were best distinguished by Urgency (committing rash decisions when faced with negative emotions), and distinguished to a lesser degree by lack of Premeditation (inability to delay action in order to plan) and Sensation Seeking (seeking excitement and adventure). Among self-injurers, lack of Perseverance (inability to stay with a task through completion) predicted more recent and frequent NSSI. Conceptual and clinical implications are discussed.
