确定关心社区（CTC）预防系统是否是一种成本效益干预措施。数据来自一个由4,407名青年组成的纵向小组，他们参加了一项随机对照试验，包括7个州的24个城镇，在州内配对，并随机分配到不同的条件。显着差异有利于干预青少年在持续禁欲从犯罪，酒精使用，烟草使用到12年级的货币化，并在CTC的经济投资相比。据估计，儿童基金会为每名青年提供了4 477美元的福利（按2011年美元折算）。执行儿童基金会5年的费用为每名青年556美元。目前净福利为3 920美元。收益成本比为每投资1美元8.22美元。内部收益率为21%。投资超过收益的风险很小。预计投资将在9年内收回。将效应减半的敏感性分析产生了积极的成本效益结果。CTC是一种具有成本效益的、基于社区的方法，用于预防犯罪、酗酒和吸烟。据估计，如果在社区中忠实地传播四氯化碳，所产生的经济效益将超过执行成本。
To determine whether the Communities That Care (CTC) prevention system is a cost-beneficial intervention. Data were from a longitudinal panel of 4,407 youth participating in a randomized controlled trial including 24 towns in 7 states, matched in pairs within state and randomly assigned to condition. Significant differences favoring intervention youth in sustained abstinence from delinquency, alcohol use, and tobacco use through Grade 12 were monetized and compared to economic investment in CTC. CTC was estimated to produce $4,477 in benefits per youth (discounted 2011 dollars). It cost $556 per youth to implement CTC for 5 years. The net present benefit was $3,920. The benefit-cost ratio was $8.22 per dollar invested. The internal rate of return was 21%. Risk that investment would exceed benefits was minimal. Investment was expected to be recouped within 9 years. Sensitivity analyses in which effects were halved yielded positive cost-beneficial results. CTC is a cost-beneficial, community-based approach to preventing initiation of delinquency, alcohol use, and tobacco use. CTC is estimated to generate economic benefits that exceed implementation costs when disseminated with fidelity in communities.
