Sustained Effects of CTC after
Five Years
Compared to control communities, 10th graders in the
panel from CTC communities showed:
• Less rapidly increasing risk since grade 5,
• Lower mean levels of targeted risk,
• Lower incidence of delinquent behavior,
alcohol use, and cigarette use,
• Lower prevalence of past-month cigarette use,
• Lower prevalence of past-year delinquency,
• Lower prevalence of past-year violence
than their 10th grade counterparts from control
communities.
