As laws expanding the accessibility of marijuana proliferate, it is increasingly important to understand how various motivations for use are differentially associated with marijuana use (e.g., frequency, quantity) and problems associated with marijuana use (e.g., reduced productivity, relationship conflict, legal issues). We conducted a meta-analytic review (k = 48, N = 11,274) of the zero-order and partial association between five marijuana use motives (i.e., coping, enhancement, social, conformity, and expansion) and a range of marijuana use outcomes (e.g., use frequency, problematic use). For marijuana use frequency zero-order correlations, we found significant positive correlations for coping, enhancement, social, and expansion, but not conformity. For marijuana use problems zero-order correlations, we found significant positive correlations for all five motives. When adjusting for the other motives, only coping, enhancement, and expansion were significantly positively associated with marijuana use frequency, and conformity was significantly negatively related to marijuana use frequency. For marijuana use problems, only coping and conformity had significant positive correlations. These results show that marijuana use motives are an important part of understanding the frequency of marijuana use and the development of marijuana use problems. These results may have implications for intervention development and public policy.
随着扩大大麻可及性的法律不断增加，了解各种使用动机与大麻使用（例如，频率、数量）和与大麻使用相关的问题（例如，生产力下降、关系冲突、法律问题）之间的差异关联变得越来越重要。我们对五项大麻使用动机（即应对、增强、社交、从众和扩展）与一系列大麻使用结果（例如使用频率、问题使用）之间的零阶和偏相关进行了元分析综述（k=48，N=11274）。对于大麻使用频率的零阶相关，我们发现应对、增强、社交和扩展与大麻使用频率呈显著正相关，但从众与大麻使用频率无关。对于大麻使用问题的零阶相关，我们发现所有五个动机均与大麻使用问题呈显著正相关。在调整其他动机后，只有应对、增强和扩展与大麻使用频率呈显著正相关，而从众与大麻使用频率呈显著负相关。对于大麻使用问题，只有应对和从众与大麻使用问题呈显著正相关。这些结果表明，大麻使用动机是理解大麻使用频率和大麻使用问题发展的重要组成部分。这些结果可能对干预措施的制定和公共政策有影响。
