这项研究考察了关怀社区(CTC)预防系统对八年级学生小组中的青少年问题行为的显著干预效果(Hawkins等人。《儿科和青少年医学档案》163：789-798 2009)是由社区层面的预防系统构建协调的，这些构建假定在CTC的变化理论中。潜在的预防系统结构包括社区在以下方面的程度：(A)采用以科学为基础的预防方法；(B)预防活动方面的协作；(C)对预防的支持；以及(D)24个社区的主要社区领导人报告的禁止青少年吸毒的规范。2004年，社区更多地采用以科学为基础的预防方法并支持预防，这预示着2007年青少年问题行为的水平将大大降低，而社区对青少年吸毒的规范水平更高，则预示着2007年青少年吸毒的水平将更低。CTC干预对八年级末青少年问题行为的影响完全是通过社区采用以科学为基础的预防方法来实现的。没有发现其他显著的中介效应。结果支持反恐委员会的变革理论，即鼓励社区采用以科学为基础的预防方法，将其作为改善青年成果的主要机制。
This study examined whether the significant intervention effects of the Communities That Care (CTC) prevention system on youth problem behaviors observed in a panel of eighth-grade students (Hawkins et al. Archives of Pediatrics and Adolescent Medicine 163: 789-798 2009) were mediated by community-level prevention system constructs posited in the CTC theory of change. Potential prevention system constructs included the community's degree of (a) adoption of a science-based approach to prevention, (b) collaboration on prevention activities, (c) support for prevention, and (d) norms against adolescent drug use as reported by key community leaders in 24 communities. Higher levels of community adoption of a science-based approach to prevention and support for prevention in 2004 predicted significantly lower levels of youth problem behaviors in 2007, and higher levels of community norms against adolescent drug use predicted lower levels of youth drug use in 2007. Effects of the CTC intervention on youth problem behaviors by the end of eighth grade were mediated fully by community adoption of a science-based approach to prevention. No other significant mediated effects were found. Results support CTC's theory of change that encourages communities to adopt a science-based approach to prevention as a primary mechanism for improving youth outcomes.
