Abstract：
The present study sought to examine three distinct research questions: a) are self-control constructs (i.e., negative/positive urgency, self-regulation, and emotion-regulation) indirectly related to negative alcohol/marijuana consequences via substance use motives, b) to what extent are these indirect effects consistent across differing drugs (i.e., alcohol and marijuana), and c) are these models invariant across gender and countries. Participants were 2,230 college students (mean age=20.28, SD=0.40; 71.1% females) across 7 countries (USA, Canada, Spain, England, Argentina, Uruguay, and South Africa) who consumed alcohol and marijuana in the last month. Two (one for alcohol and one for marijuana) fully saturated path models were conducted, such that indirect paths were examined for each self-control construct and substance use motive on negative consequences (e.g., negative urgency → coping motives → negative consequences) within the same model. Within the comprehensive alcohol model, we found that lower self-regulation and higher negative urgency/suppression were related to more alcohol consequences via higher coping and conformity motives. For marijuana, we found that lower self-regulation and higher negative urgency/suppression were related to more marijuana consequences via higher coping motives (not significant for conformity motives). Unique to marijuana, we did find support for higher expansion motives indirectly linking positive urgency to more negative consequences. These results were invariant across gender groups and only minor differences across countries emerged. Prevention and intervention programs of alcohol and marijuana around university campuses may benefit from targeting self-control related skills in addition to motives to drug use to prevent and reduce negative drug-related consequences.
摘要：
本研究试图检验三个不同的研究问题：a)是自我控制结构(即，消极/积极的紧迫性，自我调节,和情绪调节）通过物质使用动机与负面的酒精/大麻后果间接相关，B)这些间接效应在不同药物之间在多大程度上一致(即，酒精和大麻)，和c)这些模型在性别和国家之间是不变的。参与者是7个国家（美国，加拿大,西班牙,英格兰,阿根廷,乌拉圭,和南非）在上个月消费酒精和大麻。进行了两个（一个用于酒精，一个用于大麻）完全饱和路径模型，这样就检查了每个自我控制结构和物质使用动机对负面后果的间接路径(例如，消极紧迫性→应对动机→消极后果)在同一模型内。在综合酒精模型中，我们发现，较低的自我调节和较高的负面紧迫性/抑制与较高的应对和从众动机导致更多的酒精后果有关。对于大麻，我们发现,较低的自我调节和较高的负面紧迫性/抑制与较高的应对动机带来的更多大麻后果相关(对于从众动机并不显著).大麻特有的，我们确实找到了对更高扩张动机的支持，间接地将积极的紧迫性与更多的负面后果联系起来。这些结果在性别群体中是不变的，各国之间只有微小的差异。大学校园周围的酒精和大麻的预防和干预计划可能会受益于针对自我控制相关技能，以及预防和减少与毒品有关的负面后果的动机。
