Sexual minority (e.g., gay/lesbian, bisexual, and queer) students are more likely than their heterosexual peers to experience sexual violence (SV) during college. Interventions that prevent SV and improve SV care-seeking behaviors for sexual minority students are lacking. Giving Information for Trauma Support and Safety (GIFTSS) is an evidence-based universal SV intervention implemented by providers during college health and counseling visits. Compared to controls, GIFTSS participants reported greater self-efficacy to use SV harm reduction strategies and SV disclosure during clinical visits. However, GIFTSS’ effectiveness for sexual minority participants is unknown. The current study examines whether sexual orientation moderates GIFTSS’ effects on numerous SV-related outcomes (i.e., to test whether intervention effects at 4 and 12 months differed based on sexual orientation). Across 28 college campuses in Pennsylvania and West Virginia, 2,291 students participated in a two-arm cluster-randomized controlled trial. We used mixed models with two- and three-way interaction terms to test whether sexual orientation modified GIFTSS’ effects at 4- and 12-month follow-up on participants’: SV recognition; knowledge of and self-efficacy to enact SV harm reduction strategies; intentions to intervene; knowledge of and self-efficacy to use SV-related services; SV disclosure during visits; and recent SV exposure. Overall, 22.1% of participants were sexual minorities ( n = 507). Sexual orientation moderated GIFTSS effectiveness as indicated by significant three-way interaction ( p = .01) at 12-month follow-up, and knowledge of SV services decreased for heterosexual participants (β = −.23) but increased for sexual minority participants (β = .23). Our study indicates that universal provider-based education may promote greater knowledge of SV services among sexual minority than heterosexual participants, and population-specific interventions are needed that reduce sexual minority students’ SV exposure, service utilization, and other critical aspects of SV prevention on university campuses.Clinical Trial Registration: Registry name: College Health Center-based Alcohol and Sexual Violence Intervention (GIFTSS), Registration number: NCT02355470, Web link: https://clinicaltrials.gov/ct2/show/NCT02355470 , Deidentified individual participant data will not be made available.

整群随机试验中的普遍性暴力干预效果：通过性取向进行调节


性少数（例如同性恋、双性恋和酷儿）学生比异性恋同龄人在大学期间更有可能遭受性暴力 (SV)。缺乏预防 SV 和改善性少数学生 SV 寻求护理行为的干预措施。提供创伤支持和安全信息 (GIFTSS) 是一种基于证据的通用 SV 干预措施，由提供者在大学健康和咨询访问期间实施。与对照组相比，GIFTSS 参与者在临床就诊期间使用减少 SV 伤害策略和 SV 披露的自我效能感更高。然而，GIFTSS 对性少数参与者的有效性尚不清楚。目前的研究探讨性取向是否会调节 GIFTSS 对众多 SV 相关结果的影响（即测试 4 个月和 12 个月的干预效果是否因性取向而异）。宾夕法尼亚州和西弗吉尼亚州 28 个大学校园的 2,291 名学生参加了一项双臂整群随机对照试验。我们使用具有双向和三向交互项的混合模型来测试性取向是否改变了 GIFTSS 在 4 个月和 12 个月的参与者随访中的效果：SV 识别；制定 SV 伤害减少策略的知识和自我效能感；干预意图；使用 SV 相关服务的知识和自我效能感；访问期间披露 SV；以及最近的 SV 曝光。总体而言，22.1% 的参与者是性少数群体 ( n = 507)。 12 个月的随访中显着的三向交互作用 ( p = .01) 表明，性取向调节了 GIFTSS 的有效性，异性恋参与者对 SV 服务的了解有所减少 (β = −.23)，但性少数参与者的 SV 服务知识有所增加 ( β = .23)。 我们的研究表明，基于提供者的普及教育可能会促进性少数群体比异性恋参与者更多地了解 SV 服务，并且需要针对特定​​人群的干预措施来减少性少数学生的 SV 暴露、服务利用以及 SV 预防的其他关键方面。临床试验注册：注册名称：基于大学健康中心的酒精和性暴力干预（GIFTSS），注册号：NCT02355470，网页链接：https://clinicaltrials.gov/ct2/show/NCT02355470，去识别的个人参与者数据将不可用。
