We evaluated an extended model of motivation for consuming marijuana by combining motivational theory and the dualistic model of passion. An online sample of 524 young, frequent marijuana consumers (M = 24; 88% male; M=21; Mode=31; 50% used 25-31 days) self-administered several questionnaires including the Marijuana-Harmonious and Obsessive Passion Scale and the Marijuana Motives Measure. Intercorrelations among the obsessive and harmonious passion and motives subscales were small-to-medium. A canonical correlation analysis revealed that obsessive passion was significantly positively associated with coping and conformity motives, while controlling for marijuana use, other motives, and harmonious passion scores. Additionally, harmonious passion was significantly positively associated with expansion, social, enhancement, and coping motives, while controlling for marijuana use and obsessive passion scores. A second canonical correlation analysis revealed that, when motive and passion subscales were included as independent predictors of recent marijuana use and related consequences, high obsessive passion and coping motives emerged as significant predictors of recent use and related consequences. Moreover, high harmonious passion and using less for conformity motives emerged as significant predictors of recent marijuana use. These results demonstrate that passion is related to, but not a proxy for, previously established motives for marijuana use and that, when examined simultaneously, both types of passion predict recent consumption but appear to differentiate whether one will experience use-related consequences. Researchers and clinicians could evaluate whether addressing obsessive passion and coping motives reduces or ameliorates negative outcomes associated with consumption.
我们通过结合动机理论和激情二元模型，评估了一个关于吸食大麻动机的扩展模型。一个由524名年轻的、频繁吸食大麻者组成的在线样本（平均年龄24岁；88%为男性；平均年龄21岁；众数年龄31岁；50%的人吸食25 - 31天）自行填写了几份问卷，包括大麻和谐与强迫性激情量表以及大麻动机测量量表。强迫性激情与和谐性激情及动机分量表之间的相互关联程度为小到中等。典型相关分析显示，在控制大麻使用情况、其他动机以及和谐性激情得分的情况下，强迫性激情与应对和从众动机显著正相关。此外，在控制大麻使用情况和强迫性激情得分的情况下，和谐性激情与拓展、社交、增强及应对动机显著正相关。第二次典型相关分析表明，当将动机和激情分量表作为近期大麻使用及相关后果的独立预测因素时，高强迫性激情和应对动机成为近期使用及相关后果的显著预测因素。此外，高和谐性激情以及为从众动机而减少使用量成为近期大麻使用的显著预测因素。这些结果表明，激情与先前确立的大麻使用动机相关，但并非其替代指标，并且当同时进行考察时，两种类型的激情都能预测近期的消费情况，但似乎能区分一个人是否会经历与使用相关的后果。研究人员和临床医生可以评估解决强迫性激情和应对动机是否会减少或改善与消费相关的负面结果。
