Alcohol-involved sexual violence on college campuses is a complex public health challenge shaped by interacting individual, interpersonal, social, and institutional factors. This paper presents a systems science-based theory of change for addressing alcohol-involved sexual violence, developed through collaborative modeling with campus collaborators as part of the CAMPUS (Collaborative Model-building Project to Understand Sexual Violence) study.
This study presents a stock-and-flow diagram (SFD) theory of change developed by a research team through the synthesis of three causal loop diagrams co-produced by three cohorts of students and practitioners across five college campuses. The SFD formalizes key feedback structures shaping alcohol use, sexual violence, and campus responses.
The resulting SFD models the interplay of alcohol availability, drinking culture, peer norms, and consent communication. Key reinforcing loops highlight how alcohol use, consent, rape myths, and underreporting of sexual violence incidents mutually reinforce one another. Balancing loops underscore the potential of peer support and bystander interventions to interrupt these cycles. The model identifies multiple leverage points for systems-aligned interventions, including trauma-informed services and consent education.
This practice-based and collaborative model provides a systems theory of change to guide future simulation modeling and intervention design.
大学校园里与酒精相关的性暴力是一项复杂的公共卫生挑战，受到个体、人际、社会和制度等多种因素相互作用的影响。本文提出了一种基于系统科学的变革理论，用于应对与酒精相关的性暴力，该理论是通过与校园合作者进行协作建模而形成的，是“校园（理解性暴力协作建模项目）”研究的一部分。
本研究展示了一个由研究团队通过整合五个大学校园的三组学生和从业者共同制作的三个因果循环图而开发的存量-流量图（SFD）变革理论。SFD将影响酒精使用、性暴力和校园应对措施的关键反馈结构形式化。
最终的SFD对酒精供应、饮酒文化、同伴规范和同意沟通之间的相互作用进行了建模。关键的增强回路突出了酒精使用、同意、强奸谬论和性暴力事件报告不足如何相互强化。平衡回路强调了同伴支持和旁观者干预打断这些循环的潜力。该模型确定了多个与系统一致的干预杠杆点，包括创伤知情服务和同意教育。
这种基于实践的协作模型提供了一种变革系统理论，以指导未来的模拟建模和干预设计。
