Belonging to a school Gender and Sexuality Alliance (GSA) is associated with lower substance use among LGBTQ+ youth. However, it is unknown whether GSA participation facilitates access to resources for substance use concerns. Using longitudinal data from 38 Massachusetts high schools, we compared sources of support for substance use concerns listed by GSA members (n = 361) and nonmembers (n = 1539). Subsequently, we tested whether GSA membership was associated with comfort, confidence and awareness regarding substance use resources in school and the community. Finally, we assessed whether specific GSA activities and discussions (e.g. social support) were associated with these outcomes. Among students with recent substance use, GSA membership was associated with greater comfort, confidence and awareness regarding school-based substance use resources in the spring semester, adjusted for fall semester levels and non-GSA club involvement. Furthermore, students in GSAs where members reported more advocacy and social support activities reported higher levels of comfort, confidence and awareness regarding community-based substance use resources. These results indicate that among students using alcohol or nicotine products, GSA members may be more receptive to school-based substance use prevention efforts. Furthermore, GSA-based social support and activism experiences may promote access to community-based substance use resources.

性别-性联盟成员和活动：与学生对物质使用资源的舒适度、信心和意识的关联

加入学校性别与性联盟 (GSA) 与 LGBTQ+ 青年的物质使用量减少有关。然而，尚不清楚 GSA 的参与是否有助于获得物质使用问题的资源。使用来自马萨诸塞州 38 所高中的纵向数据，我们比较了 GSA 成员（n  = 361）和非成员（n = 1539）。随后，我们测试了 GSA 会员资格是否与学校和社区对物质使用资源的舒适度、信心和意识相关。最后，我们评估了特定的 GSA 活动和讨论（例如社会支持）是否与这些结果相关。在最近使用药物的学生中，GSA 会员资格与春季学期对学校药物使用资源的更大舒适度、信心和意识相关，并针对秋季学期水平和非 GSA 俱乐部参与进行了调整。此外，成员报告了更多宣传和社会支持活动的 GSA 的学生报告了对基于社区的物质使用资源的更高水平的舒适、信心和意识。这些结果表明，在使用酒精或尼古丁产品的学生中，GSA 成员可能更愿意接受以学校为基础的物质使用预防工作。此外，基于 GSA 的社会支持和行动经验可能会促进获得基于社区的物质使用资源。
