While Gender and Sexuality Alliances (GSAs) are associated with higher acceptance of sexual diversity and lower bullying-victimization, it is unclear which individual and school-level attributes strengthen these associations. Nationally representative data (N = 1,567 students; Mage = 15.4, SD = 0.16; 34% boys, 66% girls, 51% heterosexual, 49% sexually-diverse after propensity score matching) in 139 Dutch secondary schools were used. Multilevel regression analyses revealed that GSA presence was linked to more inclusive attitudes about sexual diversity and a safer disclosure climate among sexually-diverse students, and lower general bullying-victimization when the school had a GSA combined with school practices to tackle bullying. School professionals and researchers are recommended to recognize the significance of individual and school-level factors that affect GSA correlates.

虽然性别和性联盟 (GSA) 与更高的性别多样性接受度和更低的欺凌受害率相关，但尚不清楚哪些个人和学校层面的属性强化了这些关联。使用了 139 所荷兰中学的全国代表性数据（N  = 1,567 名学生；M年龄 = 15.4，SD  = 0.16；倾向评分匹配后，男孩为 34%，女孩为 66%，异性恋为 51%，性别多样化为 49%）。多级回归分析显示，GSA 的存在与对性别多样性更具包容性的态度以及性别多样化学生更安全的披露氛围有关，并且当学校将 GSA 与学校实践相结合来解决欺凌问题时，一般欺凌受害率也会降低。建议学校专业人士和研究人员认识到影响 GSA 相关性的个人和学校层面因素的重要性。
