Based on the high prevalence of marijuana use among college students, we examined distal and proximal antecedents to marijuana-related outcomes in this population. Specifically, we examined three marijuana-related perceptions (descriptive norms, injunctive norms, and internalization of college marijuana use culture) as potential mediators of the associations between four personality traits (impulsivity, sensation seeking, hopelessness, and anxiety sensitivity) and marijuana-related outcomes (marijuana use, negative marijuana-related consequences). In a large sample of college student marijuana users (n=2129), our path analysis revealed marijuana-related perceptions to significantly mediate the associations between personality and marijuana-related outcomes. Specifically, internalization of college marijuana use culture mediated the effects of both impulsivity and sensation seeking on marijuana-related outcomes. Not only do our findings suggest the importance of distinct types of marijuana-related norms in predicting marijuana involvement, but also the possibility that such normative beliefs could be targeted as part of personality-tailored interventions.
基于大学生中大麻使用的高流行率，我们在该人群中检查了与大麻相关结果的远端和近端前因。具体来说，我们检查了三种与大麻相关的认知（描述性规范、指令性规范和大学生大麻使用文化的内化）作为四个人格特质（冲动、感觉寻求、绝望和焦虑敏感）与大麻相关结果（大麻使用、负性大麻相关后果）之间关联的潜在中介。在一项针对大学生大麻使用者的大型样本（n=2129）中，我们的路径分析显示，大麻相关认知显著中介了人格与大麻相关结果之间的关联。具体来说，大学生大麻使用文化的内化中介了冲动和感觉寻求对大麻相关结果的影响。我们的研究结果不仅表明不同类型的与大麻相关的规范在预测大麻参与方面的重要性，而且还表明这种规范信念可能作为针对特定人格的干预措施的一部分被靶向。
