Illicit substance users experience adverse life events, but few studies have examined the role of impulsivity in these events. The present investigation sought to establish a link between negative life experiences and a trait measure of impulsivity and demonstrate that this association remains even accounting for potential confounds. Participants were 330 heroin and cocaine users recruited from the community for a health service research study. Participants completed a structured interview that assessed topics including drug and alcohol use, impulsivity, and negative life events. This group of drug users reported high rates of adverse life events in the 6 months prior to the assessment. No specific substance abuse/dependence diagnosis or combination of diagnoses was associated with adversity. Number of substance-related diagnoses was associated with adverse life events, but not when adjusting for impulsivity. Experience of these events was significantly associated with impulsivity (p<.001), above and beyond the shared relation with demographic variables, substance abuse and dependence, and number of substance-related diagnoses. These findings document the high frequencies of recent adverse life events among illicit drug users and indicate that trait impulsivity is associated with increased risk of these life events.
非法药物使用者会经历不良生活事件，但很少有研究探讨冲动性在这些事件中的作用。本研究旨在建立负面生活经历与冲动性特质测量之间的联系，并证明即使考虑到潜在的混杂因素，这种关联依然存在。参与者是从社区招募的330名海洛因和可卡因使用者，参与一项健康服务研究。参与者完成了一项结构化访谈，评估的主题包括药物和酒精使用、冲动性及负面生活事件。这组吸毒者报告称，在评估前的6个月里，不良生活事件发生率很高。没有特定的药物滥用/依赖诊断或诊断组合与逆境相关。与物质相关的诊断数量与不良生活事件有关，但在调整冲动性后则无关。这些事件的经历与冲动性显著相关（p<.001），超出了与人口统计学变量、药物滥用和依赖以及与物质相关的诊断数量的共同关系。这些发现记录了非法药物使用者近期不良生活事件的高发生率，并表明特质冲动性与这些生活事件风险增加有关。
