The purpose of the present investigation was to examine the unique explanatory role of cannabis use motives above the effects of each other, for the relationship between obsessive-compulsive symptomatology and different aspects of cannabis misuse among young adults. The transitional years of young adulthood are characterized by new opportunities for experimentation as well as novel external stressors. Collectively, this makes this developmental epoch a sensitive time for manifestations of cannabis misuse. Bivariate correlations were conducted to examine the association between obsessive-compulsive symptomatology and risky cannabis use, cannabis use problems, and the average quantity of cannabis used per occasion among a young ethno-racially diverse sample of college students with the past year history of cannabis use ( = 177, 68.95% female, age = 21.51, = 4.24). Next, multiple mediation analyses were conducted to examine the unique explanatory role of cannabis use motives (e.g., enhancement, conformity, coping, social, and expansion) for the association between the obsessive-compulsive symptoms and cannabis misuse variables which showed significant correlation with these symptoms at the bivariate level. Obsessive-compulsive symptoms were significantly correlated with risky cannabis use ( = .19; = .02), but not cannabis use problems or the average quantity of cannabis used per occasion. Conducting the multiple mediation for the relationship with the significant bivariate correlation, coping motives significantly explained the relationship between obsessive-compulsive symptoms and risky cannabis use ( = 0.04, = 0.02, 95% Bootstrapped CI [0.003, 0.10], Completely Standardized Indirect Effects = 0.07), after controlling for the variance accounted for by problematic alcohol use and smoking status. This indirect effect was not significant after adding anxiety and depressive symptoms as covariates to the model. These findings are discussed in terms of the development of specialized treatments to specifically target cannabis use coping motives among individuals with comorbid obsessive-compulsive disorder and cannabis misuse.
本研究的目的是探讨大麻使用动机在相互影响之外，对强迫症症状与年轻成年人中大麻滥用不同方面之间关系的独特解释作用。青年期的过渡阶段具有新的实验机会和新的外部压力源。总体而言，这使得这个发展阶段成为大麻滥用表现的敏感时期。进行了双变量相关性分析，以检验在过去一年有大麻使用史的年轻的不同种族大学生样本（n = 177，68.95%为女性，年龄 = 21.51，SD = 4.24）中，强迫症症状与危险大麻使用、大麻使用问题以及每次使用大麻的平均量之间的关联。接下来，进行了多重中介分析，以检验大麻使用动机（例如，增强、从众、应对、社交和拓展）对强迫症症状与大麻滥用变量之间关联的独特解释作用，这些变量在双变量水平上与这些症状显示出显著相关性。强迫症症状与危险大麻使用显著相关（r = 0.19；p = 0.02），但与大麻使用问题或每次使用大麻的平均量无关。对具有显著双变量相关性的关系进行多重中介分析时，在控制了问题饮酒和吸烟状况所解释的方差后，应对动机显著解释了强迫症症状与危险大麻使用之间的关系（β = 0.04，SE = 0.02，95%自抽样置信区间[0.003，0.10]，完全标准化间接效应 = 0.07）。在模型中加入焦虑和抑郁症状作为协变量后
