Mobilizing Communities

This Research Brief describes the Communities That Care prevention system, the steps involved in implementing this system, and major findings from a community randomized controlled trial (considered the “gold standard of research”) of Communities That Care.2 That study followed a panel of students from fifth through tenth grade. By the end of eighth and tenth grades, those in Communities That Care sites were less likely to start smoking cigarettes, to start drinking, and to start engaging in delinquent behavior than were their counterparts in control communities that did not use the CTC system.
