据报道，美国的年轻人压力很大，这是导致抑郁和焦虑的原因。经常使用大麻的人经常说，他们使用大麻的主要动机是为了应对压力。然而，研究表明，应对动机与潜在的负面结果有关，包括与大麻有关的问题和负面影响。因此，本研究的理论依据是，使用大麻来应对压力可能是不适应的，因为它可能会加剧使用者试图改善的问题。也就是说，使用大麻来应对可能会加剧压力和负面影响之间的联系。因此，我们试图调查大麻使用动机是否能缓和压力和负面影响之间的联系。988名使用大麻的大学生完成了一项匿名在线调查，调查内容包括大麻使用、大麻使用动机、压力、抑郁和焦虑。相关分析显示这些变量之间存在显著的正相关关系。适度分析表明，应对动机是压力与抑郁关系的显著调节因子，控制焦虑。扩张动机和从众动机是压力与焦虑关系的显著调节因子，控制抑郁。虽然大麻可以暂时缓解压力、抑郁和焦虑的症状，但使用大麻来应对可能与更高程度的抑郁有关，而使用大麻来扩大和顺从可能与更高程度的焦虑有关。这些发现具有实际意义，有助于新出现的证据表明，使用大麻的动机可能预测不同的心理健康结果。
Young adults in the U.S. report high levels of stress which are known to contribute to depression and anxiety. Regular cannabis users frequently cite coping with stress as their primary motivation for use. However, research indicates that coping motives are associated with potentially negative outcomes, including cannabis-related problems and negative affect. Therefore, the theoretical rationale for the present study is that using cannabis to cope with stress may be maladaptive as it may exacerbate the same problems users are trying to ameliorate. That is, using cannabis to cope may potentiate links between stress and negative affect. We therefore sought to investigate whether cannabis use motives moderate the associations between stress and negative affect. A sample of 988 cannabis using college students completed an anonymous online survey containing measures of cannabis use, cannabis use motives, stress, depression, and anxiety. Correlation analyses revealed significant positive relationships between these variables. Moderation analyses indicated that coping motives was a significant moderator of the relationship between stress and depression, controlling for anxiety. In contrast, expansion and conformity motives were significant moderators of the relationship between stress and anxiety, controlling for depression. While cannabis may provide temporary relief from symptoms of stress, depression, and anxiety, using cannabis to cope may be related to higher levels of depression, and use of cannabis for expansion and conformity may be related to higher levels of anxiety. These findings have practical implications and contribute to emerging evidence demonstrating that motives for cannabis use may predict differential mental health outcomes.
