Abstract Objective 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. Methods: 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 (N = 177, 68.95% female, Mage = 21.51, SD = 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. Results: Obsessive-compulsive symptoms were significantly correlated with risky cannabis use (r = .19; p = .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 (b = 0.04, SE = 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. Conclusions: 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.

强迫症状和大麻滥用：大麻使用动机的解释作用

摘要 目的本调查的目的是检查大麻使用动机在相互影响之上的独特解释作用，即强迫症状与年轻人大麻滥用不同方面之间的关系。青年时期的过渡时期的特点是新的实验机会以及新的外部压力源。总的来说，这使得这个发展时期成为大麻滥用表现的敏感时期。方法：进行双变量相关以检查强迫症症状与危险的大麻使用、大麻使用问题、以及在过去一年使用大麻历史的年轻种族多元化的大学生样本中，每次使用大麻的平均数量（N = 177，68.95% 女性，Mage = 21.51，SD = 4.24）。接下来，进行了多重中介分析，以检查大麻使用动机（例如，增强、顺从、应对、社交和扩张）对强迫症状和大麻滥用变量之间的关联的独特解释作用，这些变量显示与这些变量之间的显着相关性。双变量水平的症状。结果：强迫症状与使用大麻的风险显着相关 (r = .19; p = .02)，但与大麻使用问题或每次使用大麻的平均数量无关。对具有显着双变量相关性的关系进行多重中介，在控制了由有问题的饮酒和吸烟状况。在将焦虑和抑郁症状作为协变量添加到模型后，这种间接影响并不显着。结论：这些发现是从专门针对患有强迫症和大麻滥用的个体中大麻使用应对动机的专门治疗的发展方面进行讨论的。完全标准化的间接效应 = 0.07)，在控制了因饮酒问题和吸烟状况导致的方差之后。在将焦虑和抑郁症状作为协变量添加到模型后，这种间接影响并不显着。结论：这些发现是从专门针对患有强迫症和大麻滥用的个体中大麻使用应对动机的专门治疗的发展方面进行讨论的。完全标准化的间接影响 = 0.07)，在控制了因饮酒问题和吸烟状况导致的方差之后。在将焦虑和抑郁症状作为协变量添加到模型后，这种间接影响并不显着。结论：这些发现是从专门针对患有强迫症和大麻滥用的个体中大麻使用应对动机的专门治疗的发展方面进行讨论的。
