This paper describes the multisite, longitudinal cluster randomized controlled trial (RCT) design of the evaluation of the Dating Matters: Strategies to Promote Healthy Relationships initiative, and discusses challenges faced in conducting this evaluation.
Health departments in 4 communities are partnering with middle schools in high-risk, urban communities to implement 2 models of teen dating violence (TDV) prevention over 4 years. Schools were randomized to receive either the Dating Matters comprehensive strategy or the "standard of care" strategy (an existing, evidence-based TDV prevention curriculum). Our design permits comparison of the relative effectiveness of the comprehensive and standard of care strategies. Multiple cohorts of students from 46 middle schools are surveyed in middle school and high school, and parents and educators from participating schools are also surveyed.
Challenges discussed in conducting a multisite RCT include site variability, separation of implementation and evaluation responsibilities, school retention, parent engagement in research activities, and working within the context of high-risk urban schools and communities. We discuss the strengths and weaknesses of our approaches to these challenges in the hopes of informing future research.
Despite multiple challenges, the design of the Dating Matters evaluation remains strong. We hope this paper provides researchers who are conducting complex evaluations of behavioral interventions with thoughtful discussion of the challenges we have faced and potential solutions to such challenges.
本文描述了“约会很重要:促进健康关系的策略”倡议评估的多地点、纵向整群随机对照试验(RCT)设计,并讨论了进行该评估所面临的挑战。
4个社区的卫生部门正与高风险城市社区的中学合作,在4年内实施两种青少年约会暴力(TDV)预防模式。学校被随机分配接受“约会很重要”综合策略或“照护标准”策略(一种现有的、基于证据的TDV预防课程)。我们的设计允许比较综合策略和照护标准策略的相对有效性。对来自46所中学的多批学生在初中和高中阶段进行调查,同时也对参与学校的家长和教育工作者进行调查。
在进行多地点RCT过程中讨论的挑战包括地点差异、实施和评估职责的分离、学校留存率、家长参与研究活动,以及在高风险城市学校和社区的背景下开展工作。我们讨论了应对这些挑战的方法的优缺点,希望能为未来的研究提供参考。
尽管存在多重挑战,但“约会很重要”评估的设计仍然有力。我们希望本文能为正在对行为干预进行复杂评估的研究人员提供对我们所面临挑战的深入讨论以及应对这些挑战的潜在解决方案。
