Me & You: Building Healthy Relationships (Me & You) is a multilevel, technology-enhanced adolescent dating violence (DV) prevention program that aimed to reduce DV among ethnic-minority, early adolescent, urban youth. A group-randomized control trial of Me & You, conducted with 10 middle schools from a large urban school district in Southeast Texas in 2014–2015, found it to be effective in reducing DV perpetration and decreasing some forms of DV victimization. Economic evaluations of DV interventions are extremely limited, despite calls for more economic analyses to be incorporated in research. We help fill this gap by evaluating the cost-effectiveness from the payer and societal perspectives of implementing the Me & You program. Using cost data collected alongside the Me & You group-randomized trial, we computed incremental cost-effectiveness ratios. Our primary outcome was “any DV perpetrated” within 12 months of the intervention. We conducted a cost–benefit analysis beyond the intervention endpoint by using literature estimates of per-victim lifetime costs of DV. We performed sensitivity analyses to assess effects of uncertain parameters. Under the base-case scenario, the cost of the Me & You curriculum compared to the standard curriculum was $103.70 per-student from the societal perspective, and the effectiveness was 34.84 perpetrations averted, implying an incremental cost per perpetration averted of $2.98, which ranged from $0.48 to $73.24 in sensitivity analysis. Thus, we find the Me & You curriculum is cost-effective and cost-saving in most scenarios. Policymakers should carefully consider school-based DV prevention programs, and cost data should be regularly collected in adolescent prevention program evaluations.

我与你：建立健康的关系 (Me & You)是一项多层次、技术增强的青少年约会暴力 (DV) 预防计划，旨在减少少数族裔、早期青少年和城市青年的 DV。2014-2015 年对德克萨斯州东南部一个大型城市学区的 10 所中学进行的 Me & You 的小组随机对照试验发现，它可以有效减少 DV 犯罪和减少某些形式的 DV 受害。尽管呼吁将更多的经济分析纳入研究，但对 DV 干预措施的经济评估极为有限。我们通过从付款人和社会角度评估实施Me & You计划的成本效益来帮助填补这一空白。使用与Me &一起收集的成本数据组随机试验，我们计算了增量成本效益比。我们的主要结果是干预后 12 个月内“发生任何 DV”。我们使用文献估计 DV 的每位受害者终生成本，在干预终点之外进行了成本效益分析。我们进行了敏感性分析以评估不确定参数的影响。在基本情况下，从社会角度来看，与标准课程相比， Me & You课程的成本为每名学生 103.70 美元，有效避免了 34.84 次犯罪，这意味着每次避免犯罪的增量成本为 2.98 美元，范围不等敏感性分析从 0.48 美元到 73.24 美元。因此，我们找到了Me & You在大多数情况下，课程具有成本效益和成本节约。政策制定者应仔细考虑以学校为基础的 DV 预防计划，并在青少年预防计划评估中定期收集成本数据。
