The long-term success of child obesity prevention and control efforts depends not only on the efficacy of the approaches selected, but also on the strategies through which they are implemented and sustained. This study introduces the Multilevel Implementation Framework (MIF), a conceptual model of factors affecting the implementation of multilevel, multisector interventions, and describes its application to the evaluation of two of three state sites (CA and MA) participating in the Childhood Obesity Research Demonstration (CORD) project.
METHODS/DESIGN: A convergent mixed-methods design is used to document intervention activities and identify determinants of implementation effectiveness at the CA-CORD and MA-CORD sites. Data will be collected from multiple sectors and at multiple levels of influence (e.g., delivery system, academic-community partnership, and coalition). Quantitative surveys will be administered to coalition members and staff in participating delivery systems. Qualitative, semistructured interviews will be conducted with project leaders and key informants at multiple levels (e.g., leaders and frontline staff) within each delivery system. Document analysis of project-related materials and in vivo observations of training sessions will occur on an ongoing basis. Specific constructs assessed will be informed by the MIF. Results will be shared with project leaders and key stakeholders for the purposes of improving processes and informing sustainability discussions and will be used to test and refine the MIF.
Study findings will contribute to knowledge about how to coordinate and implement change strategies within and across sectors in ways that effectively engage diverse stakeholders, minimize policy resistance, and maximize desired intervention outcomes.
儿童肥胖预防与控制工作的长期成功不仅取决于所选方法的有效性,还取决于其实施和维持的策略。本研究引入了多层面实施框架(MIF),这是一个影响多层面、多部门干预措施实施的因素的概念模型,并描述了其在参与儿童肥胖研究示范(CORD)项目的三个州站点中的两个(加利福尼亚州和马萨诸塞州)评估中的应用。
方法/设计:采用收敛性混合方法设计来记录干预活动,并确定加利福尼亚州CORD和马萨诸塞州CORD站点实施效果的决定因素。将从多个部门和多个影响层面(例如,服务提供系统、学术-社区伙伴关系和联盟)收集数据。将对参与服务提供系统的联盟成员和工作人员进行定量调查。将对每个服务提供系统内多个层面(例如,领导人和一线工作人员)的项目负责人和关键信息提供者进行定性的半结构化访谈。将持续对与项目相关的材料进行文件分析,并对培训课程进行现场观察。所评估的具体结构将由多层面实施框架提供信息。研究结果将与项目负责人和关键利益相关者分享,以改进流程并为可持续性讨论提供信息,并将用于测试和完善多层面实施框架。
研究结果将有助于了解如何在各部门内部和部门之间协调和实施变革策略,以有效地吸引不同的利益相关者,最小化政策阻力,并最大化预期的干预效果。
