Sexual minority women (SMW) report greater rates of cannabis use. Posttraumatic stress disorder (PTSD) symptom severity is related to greater cannabis use among SMW, and it is theorized that this is due to SMW using cannabis in an attempt to manage negative affectivity associated with PTSD symptoms. However, this is the first known study to test this hypothesis. Among undergraduate women who endorsed lifetime cannabis use (N = 439, 10.5% self-identified SMW), SMW reported greater rates of cannabis use, more frequent cannabis use, greater coping-motivated use, and greater PTSD symptom severity than heterosexual women. Serial mediation analyses revealed that SMW reported more frequent cannabis use via the serial effect of PTSD symptom severity and coping-motivated cannabis use. Given the high rates of trauma exposure and cannabis use among SMW, findings suggest that SMW could benefit from exposure-based interventions in addition to cognitive behavioral skills that would teach them more adaptive strategies to manage negative affect associated with trauma exposure and PTSD symptoms.
性少数群体女性（SMW）报告的大麻使用率更高。创伤后应激障碍（PTSD）症状严重程度与 SMW 中更大的大麻使用有关，据推测，这是因为 SMW 使用大麻试图控制与 PTSD 症状相关的负面情感。然而，这是第一个已知的研究来测试这一假设。在承认终生大麻使用的女大学生中（N=439，10.5%自我认同为 SMW），SMW 报告的大麻使用率更高，使用频率更高，应对动机使用更多，PTSD 症状严重程度也更高。序列中介分析显示，SMW 通过 PTSD 症状严重程度和应对动机使用的序列效应报告了更频繁的大麻使用。鉴于 SMW 中创伤暴露和大麻使用的高发生率，研究结果表明，SMW 可以从暴露为基础的干预措施中受益，此外还可以教授他们更适应的策略来管理与创伤暴露和 PTSD 症状相关的负面情绪。
