This paper describes findings from the Community Youth Development Study (CYDS), a randomized controlled trial of the Communities That Care (CTC) prevention system, on the adoption and implementation fidelity of science-based prevention programming in 24 communities. Data were collected using the Community Resource Documentation (CRD), which entailed a multi-tiered sampling process and phone and web-based surveys with directors of community-based agencies and coalitions, school principals, service providers, and teachers. Four years after the initiation of the CTC prevention system, the results indicated increased use of tested, effective prevention programs in the 12 CTC intervention communities compared to the 12 control communities, and significant differences favoring the intervention communities in the numbers of children and families participating in these programs. Few significant differences were found regarding implementation quality; respondents from both intervention and control communities reported high rates of implementation fidelity across the services provided.
本文介绍了社区青年发展研究（CYDS）的研究结果，该研究是一项针对社区关怀（CTC）预防系统的随机对照试验，研究了 24 个社区采用和实施基于科学的预防方案的情况。数据是通过社区资源文档（CRD）收集的，该文档涉及多层次的抽样过程以及对社区机构和联盟、学校校长、服务提供商和教师的电话和网络调查。在启动 CTC 预防系统四年后，结果表明，与 12 个对照社区相比，12 个 CTC 干预社区更频繁地使用经过测试的、有效的预防方案，而且干预社区在参与这些方案的儿童和家庭数量上也有显著优势。在实施质量方面发现的差异很小；干预社区和对照社区的受访者都报告了提供的各项服务具有很高的实施一致性。
