Abstract

Purpose

In this cohort analyses, we sought to estimate the longer-term efficacy of a high-school based bystander intervention to reduce gender-based violence (GBV) into young adulthood.

Methods

Seniors were recruited from 23 of 26 high schools that participated in the original RCT (2010–2014) designed to test the effectiveness of a bystander intervention to reduce GBV. Of 3,389 high school seniors who completed an electronic survey in their last term, 1,986 complete at least one annual follow up survey through 2018 (58.6% retention). Receipt of bystander training was defined based on (1) the high school the participant attended (‘as randomized’ in the original RCT) and (2) participants’ report of additional bystander training received after high school (‘as reported’). The primary GBV outcomes were sexual violence perpetration and victimization rates (%) for the past 12 months.

Results

Only at the final follow up were significant reductions in sexual violence perpetration (SVP) noted for the ‘as randomized’ analyses. Self-reported SVP rates were 38% lower (adjusted rate ratio = 0.62; 95% Confidence Interval (CI): 0.48–0.81) among 1,107 participants who had attended schools randomized to the bystander intervention (SVP = 2.1%: 95% CI; 1.6–2.9) relative to 877 participants who had attended control schools (SVP = 3.4%; 95% CI: 3.0-3.9). Receipt of additional bystander training after high school was not associated with lower rates of any GBV form when compared with participants receiving no bystander training in or after high school.

Conclusions

Bystander training was not consistently associated with longer-term reductions in GBV perpetration nor victimization in this prospective cohort study based on a large school-based RCT.

后群组随机对照试验:旁观者计划在前瞻性队列中减少暴力实施和受害的长期效果
目的 在这项队列分析中,我们试图估算一项基于高中的旁观者干预措施的长期效果,以减少成年后的性别暴力(GBV)。方法 我们从参与原始 RCT(2010-2014 年)的 26 所高中中的 23 所招募了高三学生,该 RCT 的目的是测试旁观者干预措施对减少性别暴力的效果。在上一学期完成电子调查的 3,389 名高三学生中,有 1,986 人在 2018 年之前至少完成了一次年度跟踪调查(保留率为 58.6%)。接受旁观者培训的定义基于:(1)参与者就读的高中(原始 RCT 中的 "随机");(2)参与者对高中毕业后接受的额外旁观者培训的报告("报告")。主要的性别暴力结果是过去 12 个月的性暴力实施率和受害率(%)。结果只有在最后的随访中,"随机 "分析中的性暴力实施率(SVP)才显著下降。在随机接受旁观者干预的学校就读的 1107 名参与者中,自我报告的 SVP 发生率(SVP = 2.1%:95% CI;1.6-2.9)比在对照学校就读的 877 名参与者(SVP = 3.4%;95% CI:3.0-3.9)低 38%(调整后比率比 = 0.62;95% 置信区间 (CI):0.48-0.81)。结论 在这项基于大型校本 RCT 的前瞻性队列研究中,旁观者培训与性别暴力犯罪或受害的长期减少并不一致。

期刊介绍: The Journal of Family Violence (JOFV) is a peer-reviewed publication committed to the dissemination of rigorous research on preventing, ending, and ameliorating all forms of family violence.  JOFV welcomes scholarly articles related to the broad categories of child abuse and maltreatment, dating violence, domestic and partner violence, and elder abuse. Within these categories, JOFV emphasizes research on physical violence, psychological violence, sexual violence, and homicides that occur in families. Studies on families in all their various forms and diversities are welcome.  JOFV publishes studies using quantitative, qualitative, and/or mixed methods involving the collection of primary data. Rigorous systematic reviews, meta-analyses, and theoretical analyses are also welcome. To help advance scientific understandings of family violence, JOFV is especially interested in research using transdisciplinary perspectives and innovative research methods. Because family violence is a global problem requiring solutions from diverse disciplinary perspectives, JOFV strongly encourages submissions from scholars worldwide from all disciplines and backgrounds.
