Intimate partner violence (IPV) poses a major public health concern. To date there are few rigorous economic evaluations of interventions aimed at preventing IPV in low-income settings. This study provides a cost and cost effectiveness analysis of SASA!, a community mobilisation intervention to change social norms and prevent IPV.
An economic evaluation alongside a cluster randomised controlled trial. Both financial and economic costs were collected retrospectively from the provider's perspective to generate total and unit cost estimates over four years of intervention programming. Univariate sensitivity analysis is conducted to estimate the impact of uncertainty in cost and outcome measures on results.
The total cost of developing the SASA! Activist Kit is estimated as US$138,598. Total intervention costs over four years are estimated as US$553,252. The annual cost of supporting 351 activists to conduct SASA! activities was approximately US$389 per activist and the average cost per person reached in intervention communities was US$21 over the full course of the intervention, or US$5 annually. The primary trial outcome was past year experience of physical IPV with an estimated 1201 cases averted (90% CI: 97-2307 cases averted). The estimated cost per case of past year IPV averted was US$460.
This study provides the first economic evaluation of a community mobilisation intervention aimed at preventing IPV. SASA! unit costs compare favourably with gender transformative interventions and support services for survivors of IPV.

亲密伴侣暴力（IPV）是一个重大的公共卫生问题。迄今为止，针对低收入环境中预防IPV干预措施的严格经济评估很少。本研究对SASA!进行了成本和成本效益分析，这是一项旨在改变社会规范和预防IPV的社区动员干预措施。
在一项整群随机对照试验的同时进行经济评估。从提供者的角度回顾性收集财务和经济成本，以得出四年干预规划期间的总成本和单位成本估计值。进行单变量敏感性分析，以估计成本和结果测量中的不确定性对结果的影响。
开发SASA!活动家工具包的总成本估计为138,598美元。四年的总干预成本估计为553,252美元。支持351名活动家开展SASA!活动的年度成本约为每名活动家389美元，在干预社区中每人在整个干预过程中的平均成本为21美元，即每年5美元。主要试验结果是过去一年遭受身体IPV的经历，估计避免了1201例（90%CI：避免97 - 2307例）。过去一年避免的每例IPV估计成本为460美元。
本研究首次对旨在预防IPV的社区动员干预措施进行了经济评估。SASA!的单位成本与性别变革性干预措施以及IPV幸存者支持服务相比具有优势。
