目的：关爱社区 (CTC) 是一个预防系统，旨在通过选择和使用针对社区特定风险和保护情况量身定制的有效预防干预措施，减少青少年犯罪和药物滥用水平。本文介绍了 CTC 第一次分组随机试验的早期发现。方法：每年对 4407 名五年级学生进行调查，直至七年级。我们进行了分析，以评估在实施通过 CTC 流程选择的预防性干预措施 1.67 年后，CTC 对降低七年级目标风险因素水平以及减少犯罪行为和药物使用的影响。结果：与对照相比，CTC 社区中七年级学生的目标风险平均水平显着降低。 CTC 社区中在 5 年级和 7 年级之间开始犯罪行为的学生明显少于对照社区的学生。在七年级春季之前，没有观察到对物质使用开始的显着干预效果。结论：CTC 的变革理论假设，需要 2 到 5 年的时间来观察社区层面对风险因素的影响，并需要 5 年或更长的时间来观察对青少年犯罪或物质使用的影响。早期研究结果表明，CTC 对目标风险因素和犯罪行为引发的假设影响是有希望的。 (c) 2008 年青少年医学学会。版权所有。
Purpose: Communities That Care (CTC) is a prevention system designed to reduce levels of adolescent delinquency and substance use through the selection and use of effective preventive interventions tailored to a community's specific profile of risk and protection. This article describes early findings from the first group-randomized trial of CTC.Methods: A panel of 4407 fifth-grade students was surveyed annually through seventh grade. Analyses were conducted to assess the effects of CTC on reducing levels of targeted risk factors and reducing initiation of delinquent behavior and substance use in seventh grade, 1.67 years after implementing preventive interventions selected through the CTC process.Results: Mean levels of targeted risks for students in seventh grade were significantly lower in CTC communities compared with controls. Significantly fewer students in CTC communities than in control communities initiated delinquent behavior between grades 5 and 7. No significant intervention effect on substance use initiation by spring of seventh grade was observed.Conclusions: CTC's theory of change hypothesizes that it takes from 2 to 5 years to observe community-level effects on risk factors and 5 or more years to observe effects on adolescent delinquency or substance use. The early findings indicating hypothesized effects of CTC on targeted risk factors and initiation of delinquent behavior are promising. (c) 2008 Society for Adolescent Medicine. All rights reserved.
