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

描述（由申请人提供）：这五年的竞争性更新将评估社区护理（CTC）预防系统的长期影响。预防犯罪中心系统是一项动员社区利用预防科学规划和实施战略性社区预防服务的战略。CTC的非实验性评估表明，它可以帮助社区发展更有效的预防服务系统，减少青少年健康和行为问题（亚瑟等人，2003; Feinberg等人，2005; Harachi等人，1996;詹森等人，1997年）。目前的研究是第一个CTC疗效的随机对照试验。在本研究的干预社区中，正在忠实地实施CTC系统。该研究目前显示，在实施CTC三年后，对风险暴露和开始违法行为的早期影响。拟议的更新将评估CTC对社区预防服务系统关键方面的影响，以及在启动后9年和研究提供的资源支持CTC结束后4年对青少年吸毒，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心社区（CTC）预防规划系统的实验性测试。它的目的是找出社区使用CTC系统可以通过减少青少年吸毒率，犯罪，暴力和危险的性行为时，与不使用这种方法的社区相比，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.
