Cannabis use disorder (CUD) co-occurs with anxiety disorders at high rates. Little is known about the mechanisms linking CUD and anxiety disorders. One theoretically-driven perspective is that individuals with anxiety disorders may be more apt to use FSBs (i.e., behaviors that may be effective in decreasing anxiety in the short-term, but can maintain and even exacerbate anxiety in the long-term), which can perpetuate cannabis use despite cannabis-related problems. The present study tested whether FSB use explained the relation of anxiety symptom severity with cannabis quantity and related problems among 77 adults with CUD and comorbid anxiety disorders seeking outpatient CUD treatment. Results indicated that FSB frequency was significantly related to anxiety symptom severity and cannabis problem severity, but not cannabis quantity. Anxiety symptom severity was indirectly (via FSB frequency) related to cannabis problem severity, but not to cannabis quantity. These novel findings suggest that more frequent use of FSBs may play an important role in cannabis problem severity among individuals with CUD and anxiety disorders.
大麻使用障碍（CUD）与焦虑症的共病率很高。关于将CUD与焦虑症联系起来的机制，人们知之甚少。一种理论驱动的观点是，患有焦虑症的个体可能更倾向于使用功能不良行为（FSB，即那些可能在短期内有效减轻焦虑，但在长期内会维持甚至加剧焦虑的行为），尽管存在与大麻相关的问题，但这些行为会使大麻使用持续下去。本研究测试了功能不良行为的使用是否解释了77名患有CUD且伴有共病焦虑症并寻求门诊CUD治疗的成年人中焦虑症状严重程度与大麻使用量及相关问题之间的关系。结果表明，功能不良行为的频率与焦虑症状严重程度和大麻问题严重程度显著相关，但与大麻使用量无关。焦虑症状严重程度通过功能不良行为的频率与大麻问题严重程度间接相关，但与大麻使用量无关。这些新发现表明，更频繁地使用功能不良行为可能在患有CUD和焦虑症的个体的大麻问题严重程度中起重要作用。
