The Community Youth Development Study: A Test of Communities That Care

描述（由申请人提供）：这项为期五年的竞争性更新将评估关怀社区 (CTC) 预防系统的长期影响。 CTC 系统是一项动员社区利用预防科学来规划和实施战略性社区预防服务的战略。 CTC的非实验评估表明，它可以帮助社区建立更有效的预防服务系统，减少青少年的健康和行为问题（Arthur等，2003；Feinberg等，2005；Harachi等，1996；Jensen等，1997）。目前的研究是第一个关于 CTC 功效的随机对照试验。 CTC 系统正在本研究的干预社区中得到忠实实施。该研究目前显示了 CTC 实施三年后对风险暴露和犯罪行为开始的早期影响。拟议的更新将在 CTC 启动九年后以及研究提供支持 CTC 结束的资源四年后评估 CTC 对社区预防服务系统关键方面以及青少年吸毒、犯罪、暴力和危险性行为的影响。公共卫生相关性：社区青年发展研究是对关怀社区 (CTC) 预防规划系统的实验性测试。它的目的是找出与不使用这种方法的社区相比，使用 CTC 系统的社区是否可以通过降低青少年吸毒、犯罪、暴力和危险性行为的发生率来改善公共卫生。

DESCRIPTION (provided by applicant): This five-year competing renewal will assess the long-term effects of the Communities That Care (CTC) prevention system. The CTC system is a strategy for mobilizing communities to use prevention science to plan and implement strategic community prevention services. Non-experimental evaluations of CTC suggest that it can assist communities to develop more effective prevention service systems and reduce adolescent health and behavior problems (Arthur et al., 2003; Feinberg et al., 2005; Harachi et al., 1996; Jensen et al., 1997). The current study is the first randomized controlled trial of CTC's efficacy. The CTC system is being implemented with fidelity in the intervention communities of the current study. The study is currently showing early effects on risk exposure and the initiation of delinquent behavior after three years of CTC implementation. The proposed renewal will assess the effects of CTC on key aspects of community prevention service systems and on adolescent drug use, delinquency, violence and risky sexual behaviors nine years after its initiation and four years after study-provided resources supporting CTC end. PUBLIC HEALTH RELEVANCE: The Community Youth Development Study is an experimental test of the Communities That Care (CTC) prevention planning system. It is designed to find out if communities that use the CTC system can improve the public health by reducing rates of adolescent drug use, delinquency, violence, and risky sexual behavior when compared to communities that do not use this approach.
