Impulsivity, specifically negative urgency, is associated with diverse health risk behaviours, yet relatively little research has examined factors contributing to negative urgency. The purpose of this study was to examine the relationship between childhood maltreatment, alexithymia and negative urgency. The sample was comprised of 410 undergraduate students who completed measures online. A series of regression analyses tested whether alexithymia mediated the association between childhood maltreatment and negative urgency. Results supported the hypothesized mediation model. Subsequent analyses examined effects of specific subtypes of maltreatment and alexithymia subscales. These analyses indicated that growing up in a punishing environment (e.g. being hit or beat; expected to follow a strict code of behaviour) was indirectly associated with negative urgency via difficulty identifying feelings, suggesting that excessive use of punishment during childhood may reduce the development of the ability to identify and label feeling states. This difficulty in emotional processing may in turn lead to acting rashly when emotionally aroused.
冲动性，特别是消极紧迫感，与多种健康风险行为相关，但相对较少的研究探讨了导致消极紧迫感的因素。本研究的目的是检验童年期受虐、述情障碍与消极紧迫感之间的关系。样本包括410名完成在线测量的本科生。一系列回归分析检验了述情障碍是否介导了童年期受虐与消极紧迫感之间的关联。结果支持了假设的中介模型。随后的分析考察了受虐的特定亚型和述情障碍分量表的影响。这些分析表明，在惩罚性环境中成长（例如被打或被揍；被期望遵循严格的行为准则）通过识别情感的困难与消极紧迫感间接相关，这表明童年期过度使用惩罚可能会阻碍识别和标记情感状态能力的发展。这种情绪处理上的困难反过来可能导致在情绪激动时轻率行事。
