Compared to alcohol-only use, co-use of alcohol and cannabis is becoming increasingly more common. Impulsivity and perceived norms are two factors related to increased substance use among young adults, but few studies have examined their role in co-use. The purpose of this study was to examine whether impulsivity facets moderated the associations between perceived norms (descriptive and injunctive) for co-use frequency. Participants were college students who completed an online survey regarding their impulsivity, norms, and co-use behaviors. In the descriptive norms model, findings revealed lack of premeditation was negatively associated with co-use frequency. There was a significant interaction between descriptive norms and lack of perseverance on co-use frequency. In the injunctive norms model, findings revealed that injunctive norms were positively associated with co-use frequency; lack of premeditation was negatively associated with co-use frequency. Perceived norms and some impulsivity facets may serve as risk factors for increased co-use frequency.
与仅使用酒精相比，酒精和大麻共同使用的情况越来越普遍。冲动性和感知规范是与年轻人物质使用增加相关的两个因素，但很少有研究考察它们在共同使用中的作用。本研究的目的是检验冲动性方面是否调节了共同使用频率的感知规范（描述性和指令性）之间的关联。参与者是完成了关于他们的冲动性、规范和共同使用行为的在线调查的大学生。在描述性规范模型中，结果显示缺乏预谋与共同使用频率呈负相关。描述性规范和缺乏毅力在共同使用频率上存在显著交互作用。在指令性规范模型中，结果显示指令性规范与共同使用频率呈正相关；缺乏预谋与共同使用频率呈负相关。感知规范和一些冲动性方面可能是共同使用频率增加的风险因素。
