An Online Bystander Intervention to Prevent Teen Relationship Violence

描述（由申请人提供）：青少年关系暴力（TRV）可能对青少年的身心健康构成直接和严重的威胁。许多高中提供暴力预防方案，但很少有经过严格评估的，在少数几个对减少暴力发生率产生积极影响的方案中，大多数方案都很冗长，并且/或者需要训练有素的调解人。简而言之，需要开发具有成本效益的方法来预防TRV。这项拟议的研究将评估一种创新的在线旁观者干预措施，这种干预措施有可能比目前旨在预防TRV的方案更具成本效益。我们将招募240名9-12年级的高中生，他们将被随机分配到在线旁观者干预条件或在线对照条件。将有3个主要评估点（基线、治疗后、6个月随访）。除了使用评估旁观者行为的标准方法外，拟议的研究还将使用虚拟现实对旁观者行为进行创新的观察评估。我们相信，这种新方法有可能提供比自我报告方法更强有力的证据。此外，拟议的研究旨在深入了解治疗效果的中介和调节因素。如果在线干预以阻止TRV的方式增加旁观者行为，或者如果它减少了青少年的TRV犯罪，这项研究将为大规模评估干预奠定基础。一个有效的在线计划将在减少TRV的努力中具有巨大的潜力，因为它可以广泛地和成本效益地实施。

DESCRIPTION (provided by applicant): Teen relationship violence (TRV) can pose immediate and serious threats to a teen's physical and mental health. Many high schools offer violence prevention programs, but few have been rigorously evaluated, and of the few that have demonstrated positive effects in reducing rates of violence, most are lengthy and/or require highly trained facilitators. In short, there is a need to develop cost-effective methods for preventing TRV. The proposed research will evaluate an innovative online bystander intervention, which has the potential to be much more cost-effective than current programs designed to prevent TRV. We will recruit 240 high-school students, grades 9-12, who will be randomly assigned to the online bystander intervention condition or to an online control condition. There will be 3 primary assessment points (baseline, post-treatment, 6-month follow-up). In addition to using standard methods of assessing bystander behavior, the proposed research will use an innovative observational assessment of bystander behavior that makes use of virtual reality. We believe this new method has the potential to offer stronger evidence of program efficacy than self-report methods alone. Furthermore, the proposed research is designed to gain insights into mediators and moderators of treatment effects. If the online intervention increases bystander behavior in a manner that deters TRV, or if it reduces teens' TRV perpetration, this research will lay the groundwork for a large-scale evaluation of the intervention. An effective online program would have enormous potential in efforts to reduce TRV, because it could be implemented broadly and cost-effectively.
