This systematic review and meta-analysis evaluates the effectiveness of bystander programs that address sexual violence on college campuses. Program effects on student attitudes/beliefs and bystander behavior were examined. Durability of program outcomes and the influence of program-delivery methods (e.g., facilitator-led programs vs. video, online or poster campaign programs) and program-parameters (e.g., program length) were also evaluated.
Twenty-four studies met criteria for inclusion in the meta-analysis, and 207 separate results from these studies were coded.
Students who participated in a bystander program, compared to those who had not, had more pro-social attitudes/beliefs about sexual violence and intervening to prevent it, and engaged in more bystander behavior. Program effects diminished over time, but meaningful changes persisted for at least three months following program delivery. Longer programs had greater effects than shorter programs on attitudes/beliefs.
Bystander programs can be a valuable addition to colleges' violence prevention efforts.
本系统评价和荟萃分析评估了针对大学校园性暴力的旁观者干预项目的有效性。研究了项目对学生态度/信念和旁观者行为的影响。还评估了项目成果的持续性以及项目实施方式（例如，由主持人引导的项目与视频、在线或海报宣传项目）和项目参数（例如，项目时长）的影响。
24项研究符合纳入荟萃分析的标准，对这些研究的207个独立结果进行了编码。
与未参加旁观者干预项目的学生相比，参加该项目的学生对性暴力及干预以预防性暴力持有更多亲社会态度/信念，并表现出更多旁观者行为。随着时间推移，项目效果有所减弱，但在项目实施后的至少三个月内仍存在有意义的变化。较长的项目在态度/信念方面比较短的项目有更大影响。
旁观者干预项目可以成为高校预防暴力工作的一项有价值的补充。
