这项研究检验了终生吸食海洛因的后果是否介导了特质冲动与当前三种情绪结果之间的关系：抑郁症状、压力水平和对生活事件的感知。使用巴勒特冲动量表 (BIS-11) 对经常吸食海洛因的人 (N = 163) 进行评估，以衡量特质冲动；标准化吸毒史和使用调查问卷，用于衡量终生吸食海洛因的不良后果；贝克抑郁量表 II 用于测量当前抑郁症状；抑郁焦虑压力量表的压力子量表；以及“麻烦和提升”量表来衡量对生活事件的看法。 BIS-11 注意力和运动冲动与海洛因使用不良后果、抑郁症状和压力水平的数量呈正相关，与对事件的积极感知呈负相关。大量使用海洛因的后果与更多的抑郁症状、更高的压力、对事件的负面看法更多、注射海洛因使用以及首次和定期使用海洛因的年龄较小有关。在六种中介模型中，终生吸食海洛因的后果部分中介了两个特质冲动领域（注意力、运动）和当前情绪测量（抑郁症状、压力、事件感知）之间的关系。目前的研究结果表明，当前的负面情绪可能是对海洛因使用后果累积负担的反应，特别是在存在高特质冲动的情况下。
This study examined whether lifetime heroin-use consequences mediate the relationship between trait impulsivity and three current mood outcomes: depression symptoms, stress levels, and perception of life events. Regular heroin users (N = 163) were assessed using the Barratt Impulsiveness Scale (BIS-11) to measure trait impulsivity; a standardized Drug History and Use Questionnaire to measure lifetime adverse consequences of heroin use; Beck Depression Inventory II to measure current depression symptoms; Stress subscale of the Depression Anxiety Stress scale; and Hassles and Uplifts scale to measure perception of life events. BIS-11 Attentional and Motor impulsivity were positively related to number of adverse heroin-use consequences, depression symptoms, and stress level, and negatively associated with positive perception of events. A greater number of heroin-use consequences was related to more depression symptoms, higher stress, more negative perception of events, injection heroin use, and earlier ages of first and regular heroin use. In six mediation models, lifetime heroin-use consequences partially mediated relationships between two trait impulsivity domains (Attentional, Motor) and current mood measures (depression symptoms, stress, perception of events). The present findings suggest that current negative mood can be a response to the accumulated burden of heroin-use consequences, particularly in the presence of high trait impulsivity.
