Problematic cannabis use is highly prevalent among postsecondary students. Consequently, there is a need to examine risk factors associated with problematic cannabis use in this population. The present study investigated whether emotion dysregulation mediates the relationship between adverse childhood experiences (ACEs) and problematic cannabis use, and whether affective impulsivity (negative and positive urgency) uniquely moderates this relationship. Participants consisted of current cannabis users ( 586) recruited from five universities across Canada. Participants completed an online survey containing self-report measures of ACEs, emotion dysregulation, negative and positive urgency, and problematic cannabis use. Among the sample of postsecondary students, 36% ( = 213) met the threshold for problematic cannabis use. Moderated-mediation analyses revealed that ACEs were positively associated with emotion dysregulation and problematic cannabis use. There was also a significant indirect effect of emotion dysregulation on the association between ACEs and problematic cannabis use at moderate and high (but not low) levels of negative urgency, and at moderate and high (but not low) levels of positive urgency. The moderated-mediation models remained significant when controlling for other facets of impulsivity. Results suggest that elevated levels of emotion dysregulation and urgency are important proximal risk factors for problematic cannabis use among postsecondary students with a history of ACEs. While ACEs cannot be modified given their occurrence in the past, interventions that aim to build mindfulness and adaptive emotion regulation skills may be beneficial for reducing the likelihood that these students will engage in impulsive behaviors, such as cannabis use, when experiencing emotional distress.
问题性大麻使用在高等院校学生中极为普遍。因此，有必要研究该人群中与问题性大麻使用相关的风险因素。本研究调查了情绪失调是否介导童年不良经历（ACEs）与问题性大麻使用之间的关系，以及情感冲动性（消极和积极紧迫感）是否独特地调节这种关系。参与者包括从加拿大五所大学招募的当前大麻使用者（586人）。参与者完成了一项在线调查，其中包含ACEs、情绪失调、消极和积极紧迫感以及问题性大麻使用的自我报告测量。在高等院校学生样本中，36%（n = 213）达到了问题性大麻使用的阈值。调节中介分析表明，ACEs与情绪失调和问题性大麻使用呈正相关。在中等和高（而非低）水平的消极紧迫感以及中等和高（而非低）水平的积极紧迫感下，情绪失调对ACEs与问题性大麻使用之间的关联也存在显著的间接效应。在控制冲动性的其他方面时，调节中介模型仍然显著。结果表明，情绪失调和紧迫感水平升高是有ACEs病史的高等院校学生中问题性大麻使用的重要近端风险因素。鉴于ACEs发生在过去无法改变，旨在培养正念和适应性情绪调节技能的干预措施可能有助于降低这些学生在经历情绪困扰时从事冲动行为（如使用大麻）的可能性。
